I rarely leave negative reviews, but after our experience I feel other merchants should be aware of the risks.

A deployment made by Rebuy caused a critical issue on our Shopify store which prevented customers from accessing and using the cart. The issue effectively stopped customers from completing purchases and had a significant impact on our trading until it was identified and rolled back.

To Rebuy's credit, their support team eventually acknowledged that the issue was related to an update released from their side and subsequently reverted the change. However, the incident should never have happened in the first place, particularly given that Rebuy was not even responsible for our cart functionality.

What has been equally disappointing is the handling of the matter afterwards. The outage escalated internally to Board level due to the commercial impact on our business, yet resolving the issue required repeated chasing, long delays between responses, and multiple escalations to senior management.
After weeks of discussions regarding compensation, Rebuy ultimately agreed to release us from our 36-month contract but offered no financial compensation for the disruption caused by an outage that they themselves acknowledged originated from a Rebuy deployment.
The platform itself may work well for some merchants, but our experience exposed a concerning level of operational risk. Any third-party app capable of interfering with core checkout journeys should be subject to extremely rigorous testing before updates are pushed live.

Based on our experience, I would urge merchants to carefully consider both the technical risks and the level of accountability they can expect if something goes wrong.

As a CEO of a Shopify-based, mission-driven brand with razor-thin margins dedicated to philanthropy, I trusted Rebuy Engine to enhance our upselling and cart features without draining resources. Instead, I encountered a nightmare of misleading promises, inconsistent excuses, and outright disregard for agreed terms that not only wasted months of my time but also siphoned funds we could have used for our cause. This isn't isolated incompetence - it's a calculated approach that preys on busy merchants, and it could devastate your business too.

Installation started in March 2025, but the real issues emerged with billing. During onboarding, Nasik explicitly agreed to a fixed $99/month rate for V4 pricing on a 12-month commitment, excluding Monetize features we didn't need (confirmed in our call and referenced in emails on Nov 7, 2025). This was echoed by Nick Hein as a "win for all parties" if we continued.

Yet, from August onward, we were slammed with $499/month charges - three times the agreed rate: $499 on Aug 12, Sept 11, and Oct 11, totaling $1,497 in overcharges. When confronted in October, Cole Baines feigned ignorance, claiming "no record" of the $99 deal despite Nasik's clear confirmation (Nov 7: "we agreed to have them on v4 pricing at $99/month"). Cole twisted it further, arguing our generated revenue (around $14,000 in 30 days) justified the hike, ignoring our heavy investment in custom setups like a meal counter - assisted by their team under the false premise of the low fixed rate.Resolution attempts were a farce. Responses lagged for days (e.g., my Nov 7 billing renewal query was initially ignored), and offers flip-flopped: Oct 23 promised a $1,006.59 credit (but only in-app, not refunded), Nov 4 downgraded to one $499 "goodwill" refund tied to ROI, dismissing the original pact. By Nov 13, I demanded the full overcharge refund and transition time; Nick processed one refund but demanded immediate uninstallation. In December, I requested brief access to retrieve our custom cart code. Access was reactivated temporarily (Dec 29) but yanked abruptly on with a dismissive "good luck" sign-off.

This pattern screams bait-and-switch: lure with low rates, bill exorbitantly, deny agreements, and stonewall refunds. No proactive outreach on discrepancies; I chased every step, pulling focus from scaling our store during peak seasons. The financial hit? Over $1,000 lost, plus untold hours - resources that could fund real impact. Online searches reveal a chorus of similar horror stories: overbilling, ghosting support, and unkept promises, suggesting Rebuy prioritizes extraction over ethics.Fellow merchants: Steer clear of Rebuy Engine.

Their tactics erode trust in the Shopify ecosystem and could cripple your operations. We've switched to in-house tools. Don't let them exploit you - demand better from your partners.
