Rebuy review and real cost

AI upsells across cart, checkout and post-purchase, plus search and A/B testing for Shopify.

Good, with caveats6/8 checks passed#2 of 3 in upsell and cross-sellBy Rebuy4.7 from 854 App Store reviews

Verdict

Rebuy suits growing stores that want cart, checkout and post-purchase upsells in one app and accept a bill that rises with orders. The catch: every package is priced on orders, and above 7,500 orders a month you need a sales quote.

Install it if

  • Stores of 500 to 7,500 orders a month that want cart and post-purchase upsells in one app
  • Brands that will use A/B testing and Smart Flows to tune offers
  • Teams that want a customer success manager and can pay for premium support

Skip it if

  • Stores that want a flat monthly price
  • Stores above 7,500 orders a month that do not want to negotiate a quote
  • Merchants who want a quick, hands-off setup

Good

  • Covers cart, checkout, post-purchase offers and search in one app1.
  • You pay only for the packages you use, with up to 30% off when you bundle1.
  • Names a SOC 2 Type II report in its trust centre3.
  • Documents a Shopify Flow trigger for post-purchase events6.

Not so good

  • Each package's price rises with orders: Checkout & Post-Purchase goes from $25 at 500 orders to $96 at 2,0002.
  • Above 7,500 orders a month, pricing is by quote only2.
  • No Built for Shopify badge on the listing1.
  • Recent low ratings cite billing disputes and setup trouble7.

How we worked out the bill

What it does

Rebuy is a personalization suite for Shopify stores: a slide-out Smart Cart, upsell widgets, checkout and post-purchase offers, search, and A/B testing1. You buy it as four packages that you mix and match, and each is priced on your orders a month2.

Rebuy Monetize is free. It shows other brands' offers on your thank-you page and pays you per order1.

  • Smart Cart: a slide-out cart with AI product recommendations1,2.
  • Post-purchase offers, plus checkout extensions on Shopify Plus2.
  • A/B testing, Smart Flows and reorder landing pages2.
  • Smart Search and Smart Collections for product discovery2.
  • Rebuy Monetize puts other brands' offers on your thank-you page and pays you per order1.
  • Shopify Flow trigger for post-purchase events, for tagging orders and automations6.

What merchants say

Rebuy holds 4.7 from 854 reviews, and 806 of them are five stars1. Recent reviews praise the account managers and the lift in order value from the Smart Cart and post-purchase offers1. The low ratings repeat a few themes: billing disputes, a hard setup, and one report of a Rebuy update that broke a store's cart until it was rolled back7.

Complaints worth knowing

  • A UK merchant reported that a Rebuy update stopped shoppers using the cart until Rebuy rolled it back7.
  • Several recent low ratings describe billing disputes and large unexpected charges7.
  • One merchant found the free plan's post-purchase offers were third-party ads, not their own products7.
  • Some new users found setup complex and the help docs out of date7.

What the developer claims

Numbers the developer publishes about itself. We have not verified them.

  • Rebuy Monetize earns $0.20–0.35+ per order1.
  • Rebuy guarantees a positive ROI; refund requests must be made within 60 days of billing2.
