Wiser vs Rebuy: Which Shopify Personalization App Is Right for You?

WISER VS Rebuy – The Two Apps That Dominate the Shopify Personalization App Space. So, which one actually fits your business better? 

Getting more traffic to your Shopify store is expensive. The smarter move is to make more revenue from the traffic you already have. That is exactly where personalization apps make the biggest difference.

When customers see the right product recommendations, smart upsells, relevant bundles, and timely post-purchase offers, they buy more, convert faster, and come back again. A well-placed “Frequently Bought Together” widget or checkout upsell can often drive more revenue than another paid ad campaign.

Two apps that dominate this space are WISER and Rebuy. If you have been searching for the best Shopify personalization app and kept landing on Wiser and Rebuy as your two strongest options, you are in the right place. Both are genuinely excellent and popular Shopify personalization apps built to increase average order value (AOV), improve conversions, and create personalized shopping journeys, but they do it in very different ways.

Rebuy is known for deep checkout personalization, Smart Cart experiences, and advanced automation built for larger brands.

WISER focuses on AI-powered recommendations, Frequently Bought Together bundles, upsells, post-purchase offers, and personalized product discovery with a more flexible and affordable setup for growing stores.

Both apps promise to grow your revenue through AI-powered product recommendations. The difference is who they are built for, what they cost, and what happens when your store scales. So which one actually fits your business better? 

Choosing between them on features alone misses the point. This guide compares WISER vs Rebuy based on features, pricing, ease of use, personalization depth, and which type of Shopify store each app is best for.

WISER VS Rebuy – Quick Overview Of Both The Apps

Wiser AI — Full-Funnel Personalization at an Accessible Price

WISER is an AI-powered product recommendation and upsell app built for Shopify, developed by Expert Village Media Technologies. WISER Shopify personalization app covers the complete purchase funnel right from the search bar to product pages, cart, checkout, post-purchase, and email, all from a single dashboard. WISER is a rebuy alternative that uses item-to-item collaborative filtering to personalize recommendations for each shopper based on their real-time behaviour and purchase history.

Global brands, including BBC Shop, Philips, Decathlon, Victoria Beckham, and more, use Wiser to power their recommendation and upsell strategy. With 4.9 stars from 500+ reviews, the pricing of this app starts at $9/month, including a free plan for stores under 50 orders/month. WISER is designed to be accessible to growing stores and powerful enough for established brands.

Rebuy Engine — Enterprise Personalization for Scaling Shopify Brands

Rebuy is a comprehensive e-commerce personalization platform trusted by Shopify brands, including Momofuku, Liquid Death, Magic Spoon, Patagonia, and Olly.

The plans start at $99/month with a 21-day free trial, scale to $999/month for enterprise stores, and operate on a revenue-based model in which pricing increases as Rebuy drives more incremental revenue for your store.

Here is the list of the Best Upsell Apps for Shopify to Increase Sales and AOV.

WISER vs Rebuy – Breakdown on Pricing

Pricing is where the two apps rebuy and rebuy alternative – WISER diverge most dramatically, and where choosing the wrong one can either leave money on the table or create a monthly bill that does not match your store’s current stage. 

Important note on Rebuy Pricing

Rebuy uses a Rebuy-Generated Revenue (RGR) model.The pricing automatically escalates as Rebuy drives more revenue for your store.Once you exceed the revenue threshold of your current plan, you move to the next tier automatically. While this aligns Rebuy’s incentive with yours, it means your monthly cost is variable and can increase significantly during high-traffic periods like BFCM. (Always model your costs at your peak order volume, not average.)

The gap between the WISER pricing and the Rebuy app pricing is significant and real. A store getting 20 to 50 orders pays $0 per month; anything more than 50 orders starts at only with $9/month with Wiser, but $99/month with Rebuy, before factoring in which package features you need. For a growing store where every dollar of app spend needs to be justified, this difference matters enormously.

WISER vs Rebuy – Where WISER Takes Over?

1. Price-to-value ratio for growing stores

Wiser’s most significant advantage is delivering full-funnel AI personalization, from search through the IntelliSearch feature to the product page, cart drawer and cart page recommendation, checkout, post-purchase upsells, and email. All at a price point that growing stores can actually afford. At $9/month to start and a genuinely free plan for new stores, WISER AI removes the financial barrier that prevents many merchants from using AI personalization at all. The features you get at $9/month with WISER would cost at least $99/month with Rebuy.

2. AI Frequently Bought Together — Smarter Bundles Without the Complexity

Rebuy offers a Frequently Bought Together widget. So does Wiser. But here is where the difference matters – WISER’s AI FBT is powered by item-to-item collaborative filtering that analyses your store’s real purchase history, browsing behaviour, products viewed but not purchased, and customer preference signals. This automatically identifies which products are most commonly bought together and surfaces them as a one-click bundle on your product page.

No manual product grouping. No guessing which items pair well. The AI finds the patterns in your actual order data and does the work for you.

What makes this a direct advantage over Rebuy is simplicity at the merchant level. Rebuy’s Dynamic Bundles and Bundle Builder are powerful, but they require configuration, design choices, and ongoing management. WISER’s AI Frequently Bought Together starts working from the moment it has order data to learn from, surfacing relevant combinations automatically, and that is exactly what Wooden Ships, one of WISER’s featured merchants, used to generate $46,000 in additional revenue. 

For a store with hundreds of SKUs, that is the difference between a bundle strategy that runs itself and one that requires constant maintenance. 

3. IntelliSearch — Personalized AI Search That Rebuy Cannot Match

Rebuy has a Smart Search feature. Wiser has IntelliSearch, and both offer AI-powered search with fast results, typo correction, and the ability to handle vague queries. However, their core focus is different and meaningful. Wiser IntelliSearch is designed to drive more sales, not just help users find products. It shows personalized results based on each shopper’s behaviour and adds recommendations, trending products, and upsell suggestions directly within the search experience. This turns every search into an opportunity to increase conversions and average order value.

Rebuy Smart Search is more focused on product discovery and merchandising, helping shoppers find the right products quickly while giving store owners strong control over search results and detailed insights to improve merchandising decisions. While it does offer personalization, it is not as deeply tailored to individual user behaviour as Wiser.

Another key difference is in filters and pricing. Wiser automatically creates smart filters from your product catalogue without manual setup, whereas Rebuy manages this through separate features. At Rebuy’s starting price of $99/month, Smart Search is part of a broader package. With Wiser, IntelliSearch is available from $9/month, making enterprise-quality personalized search accessible to stores at every stage.

In simple terms, Rebuy helps customers find products more efficiently, while Wiser goes a step further by using search as a tool to increase sales through personalization and upsell opportunities.

4. WISER Cart Drawer and Cart page recommendations

Rebuy Smart Cart and Wiser Cart Drawer work in very different ways. Rebuy completely replaces your Shopify cart with its own advanced cart system, while WISER simply adds AI recommendations inside your cart drawer or existing cart. This means with Wiser, your current cart design stays the same, and you just get smart upsell and cross-sell suggestions. 

With Rebuy, you are building a new cart from scratch, while Wiser focuses on easy upsells and personalization. It shows products like frequently bought together, related items, trending products, and personalized suggestions based on customer behaviour. It’s simple to set up, works with your current theme, and is much more affordable, starting from $9/month. It’s ideal if you want to increase order value without changing your cart setup.

Rebuy Smart Cart is built for advanced cart optimization. Its features include free shipping progress bars, “buy more save more” offers, free gifts, subscription upsells, countdown timers, and deep integrations with other apps. You also get full design control with a drag-and-drop builder. However, all this comes at a higher price, starting from $99/month, and may require more setup.

In simple terms, Wiser enhances your existing cart with smart recommendations, while Rebuy rebuilds your cart with some advanced features, asking you to loosen your pockets in return.

5. Email recommendations are a unique differentiator

WISER includes personalized email product recommendations as a native feature, integrating with Klaviyo and other email platforms to inject AI-curated product suggestions into order confirmations, shipping updates, newsletters, and win-back campaigns. Rebuy does not offer Email product recommendations natively. For stores where email is a primary revenue channel (which it should be for every store), this is a meaningful gap in Rebuy’s offering that WISER fills.

3. Wiser Smart AI-triggered upsell pop-ups

WISER’s pop-up recommendation feature shows AI personalized upsell offers in smart, condition-triggered pop-ups. This adds a touchpoint for AOV growth that Rebuy does not cover with a dedicated feature. For stores that want to surface offers without the shopper having to reach the cart, this fills an important gap in the funnel. Check out the hacks for Higher AOV using WISER AI Upsell App.

4. Product quiz for guided discovery

WISER includes an interactive product quiz that guides shoppers to the right product through their own stated preferences. This is particularly valuable for beauty, health, skincare, and supplement stores where product-customer fit is crucial and the catalogue can feel overwhelming. Rebuy does not have an equivalent native feature.

5. Simpler setup, faster time to value

WISER is a fully no-code Shopify personalization app designed to be installed and running in minutes, with AI product recommendations that immediately learn from your existing order data. Rebuy offers significant flexibility, including low-code and custom code options — but that flexibility comes with setup complexity that requires more time, technical knowledge, or developer support to unlock fully.

WISER vs Rebuy – Where Rebuy Wins?

1. Smart Cart is the most advanced cart on Shopify

Rebuy’s Smart Cart is genuinely best-in-class. It is a fully customizable slide-out cart with 35+ pre-built integrations, tiered progress bars, buy-more-save-more mechanics, gift-with-purchase, switch-to-subscription, countdown timers, and AI-powered upsells, all built into the cart experience. If your store’s primary conversion challenge is cart abandonment and you want the most sophisticated cart available on Shopify, Rebuy wins this category clearly.

2. Dynamic Bundles and Bundle Builder

Rebuy’s Dynamic Bundles and Bundle Builder let shoppers build their own custom bundles from scratch with flexible bundling logic, multiple SKU combinations, related-product offers, and subscription bundle options. This is a dedicated bundling feature set that Wiser does not have natively. For stores where product bundles are a primary AOV strategy, this is a significant Rebuy advantage.

3. Smart Flows with advanced automation

Rebuy’s Smart Flows allow merchants to build complex, logic-based automation workflows that connect search, cart, checkout, and post-purchase experiences — reducing steps to checkout, driving conversions through conditional logic, and creating shareable pre-populated cart links. This level of automation sophistication is beyond what Wiser currently offers.

4. Rebuy Monetize post-purchase ad revenue

Rebuy Monetize, powered by Fluent, lets merchants earn additional revenue from their post-purchase thank-you and order status pages by displaying high-quality sponsored offers from partner brands, at zero additional cost to the merchant. This is a unique revenue stream that no competitor offers, and it lowers Rebuy’s effective cost below its headline price for stores with meaningful order volume.

5. Enterprise infrastructure and dedicated success management

Rebuy has powered over $3.8 billion in additional revenue and is trusted by enterprise brands including Patagonia, Olly, and Magic Spoon. Its Enterprise plan includes dedicated Customer Success Managers, private Slack channels, white-glove setup services, and an ROI guarantee. For Shopify Plus brands at scale that need enterprise-grade support and accountability, Rebuy’s infrastructure is genuinely superior.

Rebuy or Rebuy Alternative – Which one Should You Choose?

Choose WISER AI, If …

1. You are a growing Shopify store, at any order volume, and want full-funnel AI personalization without a $99–$499/month app bill. Wiser’s pricing is based on your monthly store orders, not a fixed enterprise tier. The free plan covers up to 50 orders/month. Paid plans scale affordably with your growth. You get the same AI engine used by global brands at a price that makes sense for where your store is right now. Follow these best practices for Shopify store growth.
2. You want every recommendation touchpoint covered from one app, not just five. Wiser covers the complete purchase funnel: AI-powered recommendations inspired by browsing behaviour, Frequently Bought Together bundles, cart page and cart drawer upsells, checkout page upsell, post-purchase upsell with funnels, thank-you page recommendations, order status page upsell, email recommendations, Wiser Pops (smart popup upsells), Wiser Quiz for guided discovery, and IntelliSearch — all from one dashboard, one subscription, one support team.
3. You want email recommendations integrated with Klaviyo and other email platforms as part of your personalization stack, not a separate tool. Wiser injects AI-curated product suggestions into order notifications, shipping updates, newsletters, and account emails. Every email your store sends becomes an additional revenue opportunity. Rebuy does not offer this natively at any price tier.

4. Your store is in fashion, beauty, health & wellness, electronics, pet, food & beverage, or any category where showing the right product to the right person drives the most value. Wiser’s item-to-item collaborative filtering learns from your real purchase patterns and adapts to each individual shopper’s behaviour — making it particularly powerful for stores where product-customer fit determines whether a sale happens.
5. You want to be live with AI recommendations in under 30 minutes without developer support. Wiser works with every Shopify theme via native theme blocks and app extensions — no code, no developer, no theme conflicts. The support team (real people, consistently praised across 400+ five-star reviews) is available to customize the app to your store’s specific design requirements at no extra cost.
6. You want a free plan to test AI recommendations before committing to a paid tier. Wiser’s free plan is available to stores with up to 100 orders/month, and includes AI-based recommendations, Frequently Bought Together, related products, manual recommendations, best sellers and new arrivals, and detailed analytics and reports. You can prove ROI before spending a single dollar.
7. You want A/B testing built in so you can optimize your recommendation strategy with real data. Wiser includes A/B testing for recommendation widgets, so you can test different widget types, placements, and product combinations and let the data tell you what converts best for your specific audience.
8. You want Wiser Pops AI-triggered smart pop-ups as part of your toolset without a separate app. Wiser Pops shows personalized upsell offers in beautifully designed popups triggered by smart conditions, catching shoppers at high-intent moments before they reach the cart. Rebuy has no native equivalent.

9. You want an interactive product quiz that guides shoppers to the right product. Wiser Quiz delivers personalized recommendations based on each shopper’s stated preferences — improving both engagement and conversion for stores in beauty, health, skincare, and supplements where shoppers need help finding the right product in a large catalogue.
10. You want pricing that scales with your order volume, not arbitrary feature locks. On Wiser, every plan includes the core feature set. You pay more as you grow — but you are not blocked from accessing key features at lower tiers. The enterprise plan adds post-purchase upsell with funnels, checkout page recommendations, advanced IntelliSearch, Wiser Cart advanced cart drawer, order status page upsell, FBT with bundle discounts, API access, fortnightly performance reports, and a dedicated account manager.
11. You are on Shopify or Shopify Plus and want a platform actively used by global brands at both ends of the spectrum. Wiser is a certified Shopify Plus app used by enterprise brands including Mamaearth, Philips, BBC Shop, Decathlon, Paramount Shop, and WB Shop, while remaining genuinely accessible to small and mid-size stores through its order-based pricing model and free plan.

Choose Rebuy … If …

1. You are an established Shopify or Shopify Plus brand doing 1,000+ orders/month with a dedicated budget for a premium personalization platform, and your primary goal is a heavily customized cart experience. Rebuy’s entry point starts at $99/month and scales to $999/month, a price level that is justified only when your store has the order volume and revenue to absorb it and the team to use the platform’s full depth. For stores at that scale who specifically want a cart-replacement solution with deep customization options, Rebuy’s Cart & Merchandising package delivers a feature set that goes beyond what a standard cart-layer approach offers.
2. Your absolute top priority is a fully rebuilt slide-out cart with tiered incentive mechanics built in — and you are willing to replace your existing cart entirely to get it. Rebuy Smart Cart is a complete cart replacement, not an add-on. It removes your existing Shopify cart and substitutes Rebuy’s own slide-out cart system — giving you drag-and-drop design control, tiered free shipping progress bars, Buy More Save More volume discount mechanics, countdown timers, and announcement banners inside the cart. These are cart incentive mechanics, not recommendation features, and they require rebuilding your cart from the ground up. If those specific mechanics are your primary AOV lever and you have the setup time and budget, Rebuy’s Smart Cart covers them in one place.
3. You sell subscription products and want a one-click “switch to subscribe” option embedded directly inside the cart — and you have the order volume to justify Rebuy’s pricing for that single feature. Rebuy Smart Cart includes a built-in subscribe-and-save conversion mechanic that lets shoppers switch from a one-time purchase to a recurring subscription with a single click at the cart stage, without leaving the cart experience. Brands using this feature report 25–30% subscription sign-up increases from the cart. Note that this requires Rebuy’s full platform — it is not available as a standalone feature.
4. You want 40+ third-party app integrations — loyalty programs, review platforms, subscription apps, shopping protection services — surfaced inside the cart experience itself, and your tech stack already includes Klaviyo, Yotpo, Recharge, Gorgias, Okendo, or Attentive. Rebuy Smart Cart connects to 40+ apps and can surface signals from those apps — a customer’s loyalty point balance, a review prompt, a protection upsell — directly inside the cart without additional page navigation. This integration depth is a genuine strength for brands already running a complex multi-app stack who want the cart to act as a hub for all of it.
5. Product bundling — specifically, customer-facing Bundle Builder or AI-powered Dynamic Bundles — is a central part of your AOV strategy that you cannot replicate with a standard Frequently Bought Together widget. Rebuy offers both Dynamic Bundles (AI-automated) and a customer-facing Bundle Builder where shoppers mix and match products to create their own bundles, often paired with volume discounts. This is a dedicated bundling feature set that goes beyond FBT-style suggestions. If bundles are your primary product and revenue mechanic — rather than a supplementary upsell — Rebuy’s bundle tools offer that depth. Note that Wiser’s AI Frequently Bought Together with bundle discounts covers the most common bundling use case for most stores at a significantly lower price point. Learn how to choose the right Shopify product bundles.
6. You want Smart Flows — a visual, logic-based automation builder that connects search, cart, checkout, and post-purchase into conditional workflows — and you have the time and technical familiarity to build and maintain those workflows. Rebuy’s Smart Flows allow merchants to create rule-based automation logic: if a shopper has purchased before, show X; if their cart contains product Y, trigger Z; if they came from a specific UTM source, route them differently. This kind of conditional, multi-step automation is genuinely powerful for brands with complex personalisation requirements that go beyond standard widget placement. It requires meaningful setup time and ongoing management to use well.
7. You are a Shopify Plus merchant with a team large enough to need a dedicated Customer Success Manager, a private Slack support channel, and white-glove onboarding — and your budget is at the Enterprise plan level ($999/month+). Rebuy’s Enterprise plan includes hands-on setup support, a dedicated CSM, direct Slack access, and activation services. This level of support is valuable for large brands that need someone accountable for their platform performance and do not want to rely on standard ticket-based support. For brands that do not need this level of managed support, paying for it at the Enterprise plan price point is not necessary — Wiser’s support team (consistently praised across 400+ reviews) handles setup, customisation, and ongoing issues for every merchant regardless of plan.
8. You want to leverage Rebuy’s formal positive ROI guarantee as a condition of committing to the platform. Rebuy offers a documented positive ROI guarantee — if the incremental revenue Rebuy generates for your store does not exceed what you pay for the platform within a defined window, Rebuy will work to make it right. This guarantee applies to merchants who make a genuine effort to use the product and submit a refund request within 60 days of billing. It is a meaningful commitment that reflects Rebuy’s confidence in their platform at high order volumes. Merchants who want that formal accountability structure before committing to a $99–$999/month subscription will find the guarantee reassuring.
9. You want to earn additional revenue from your post-purchase thank-you and order status pages through Rebuy Monetize — a feature that no competing personalization app offers. Rebuy Monetize, powered by Fluent, displays high-quality sponsored product offers from partner brands on your post-purchase pages — at zero additional cost to your customers and with revenue sharing back to your store. For high-volume brands, this can meaningfully offset the cost of the Rebuy subscription itself. It is a genuinely unique revenue stream with no direct equivalent in Wiser or any other Shopify personalization platform. If this post-purchase monetization mechanic is important to your revenue strategy, it is only available through Rebuy.
10. You have developer resources in-house or via an agency and want low-code or custom code control over your personalization experience — including API access, custom Smart Cart templates, and React or Hydrogen integration for headless builds. Rebuy is designed to accommodate both no-code merchants and technical teams who want deeper control. Its API, custom cart template documentation, and Hydrogen support make it one of the few personalization platforms that genuinely scale from drag-and-drop to fully custom implementations. If your store runs a headless Shopify build or your team wants to extend Rebuy’s functionality beyond standard configurations, this technical flexibility is a real advantage. For merchants without developer resources, this flexibility is irrelevant — and Wiser’s fully no-code setup delivers the core personalisation value without requiring it.

The Verdict on WISER vs Rebuy

Both Wiser AI and Rebuy are powerful Shopify personalization apps, but they are built for different types of stores.

Wiser AI — Best for Growing Shopify Stores

Wiser is a great choice for small and growing stores that want affordable AI personalization without spending hundreds of dollars every month. It includes AI recommendations, Frequently Bought Together, cart and checkout upsells, post-purchase offers, email recommendations, IntelliSearch, A/B testing, quizzes, and pop-ups — all in one platform. It is easy to set up, works without coding, and even offers a free plan to help stores get started risk-free.

6 Must-Do Actions, WISER AI Post Installation Steps.

Rebuy Engine — Best for Large Enterprise Stores

Rebuy is better suited for large Shopify Plus brands with bigger budgets and advanced customization needs. Features like Smart Cart, Dynamic Bundles, Smart Flows, and Rebuy Monetize are built for stores handling high order volumes and complex personalization strategies. It offers deep customization and enterprise-level tools, but comes with a much higher monthly cost.

WISER vs Rebuy: Which one to choose?

The comparison is not really “Wiser vs Rebuy.” It is “Which stage is your store at?” Wiser is built for the merchants who are growing and need powerful AI personalization at an accessible price. Rebuy is built for the brands that have already grown and can invest in an enterprise-grade platform. Both are excellent at what they do, for the store they are designed for. 

Here is the list of 17 Best Shopify Apps to Increase Sales in 2026.

Frequently Asked Questions – WISER vs Rebuy

1. Is WISER a good Rebuy alternative?

Yes — for most growing Shopify stores, Wiser is an excellent Rebuy alternative. It covers the same core personalization funnel (product recommendations, FBT, cart upsell, checkout upsell, post-purchase, and search) at a fraction of the price. Wiser delivers comparable AI personalization quality with a significantly lower cost of entry, including a free plan that Rebuy does not offer. 

2. Which Shopify personalization app is better for small stores?

Wiser is clearly better for small Shopify stores. Its free plan covers stores under 50 orders/month, and paid plans start from $9/month — compared to Rebuy’s minimum of $99/month. For a store doing under 500 orders/month, the pricing difference alone makes Wiser the rational choice.

3. Which Shopify personalization app, WISER or Rebuy, is better for Shopify Plus stores?

Both apps work on Shopify Plus, but they suit different Plus merchants. Rebuy is purpose-built for enterprise Shopify Plus brands — its Smart Cart, Smart Flows, dedicated Customer Success Managers, and ROI guarantee are specifically designed for large-scale operations. Wiser supports Shopify Plus fully and is the better choice for Plus merchants who want strong AI personalization, email recommendations, and quiz features without the overhead of Rebuy’s pricing and complexity. Brands like BBC Shop and Philips use Wiser on Shopify Plus. 

4. Does WISER have the same AI quality as Rebuy?

Both apps use AI-powered product recommendation engines based on collaborative filtering and machine learning. Wiser uses item-to-item collaborative filtering along with custom rules that analyze real purchase patterns and real-time browsing behaviour to personalize recommendations for each shopper. Rebuy uses a combination of AI and a custom rules engine that allows merchants to layer manual merchandising logic on top of AI suggestions. Both deliver strong recommendation quality.

5. Can I switch from Rebuy to WISER?

Yes. Wiser installs directly from the Shopify App Store and connects to your store’s existing product catalogue and order history. Setup takes under 30 minutes for most merchants, and Wiser’s support team can assist with the transition at no additional cost. Many merchants switching from Rebuy find that Wiser covers their core recommendation and upsell needs while significantly reducing their monthly app spend. If you specifically rely on Rebuy’s Smart Cart, Dynamic Bundles, or Smart Flows, those would need to be replaced with alternative tools before switching.  

6. Does WISER offer email product recommendations?

Yes, this is one of Wiser’s clearest advantages over Rebuy. Wiser integrates with Klaviyo and other email platforms to inject personalized, AI-curated product recommendations into order confirmation emails, shipping updates, newsletters, win-back campaigns, and back-in-stock alerts. Each recipient sees products personalized to their specific purchase history and browse behaviour. Rebuy does not offer native email recommendations, making Wiser the stronger choice for merchants who want their email channel and on-site personalization powered by the same AI engine. 

7. How long does it take to set up Rebuy and rebuy alternative WISER?

Wiser is designed for quick, no-code setup. Most merchants have their first recommendation widget live within 30 minutes of installation, with AI recommendations immediately drawing on existing order history. Rebuy also offers no-code setup for standard configurations, but the full feature depth Smart Flows, custom Smart Cart builds, and API integrations require significantly more setup time and often benefit from developer support or Rebuy’s paid activation services.
