Tired of Rebuy Taking a Cut of Your Top-Line Revenue? Switch to Flat-Fee Supercart.
Rebuy charges hundreds to thousands of dollars every month PLUS a percentage of your gross merchandise value (GMV). Supercart gives you intelligent cross-sells, tiered rewards bars, and self-insurance at a flat, predictable monthly tier with strictly 0% commission.
The Guarantee: Slash your SaaS tech stack spend by $1,500 to $5,000+ every month—even if you run complex customer segmentation or multi-currency Shopify Plus stores.
The GMV Tax Trap: Penalizing Your Brand for Growing
Enterprise merchandising platforms like Rebuy employ a predatory 'revenue share' pricing model. When your marketing team executes a high-converting campaign, scales TikTok or Meta ad spend, or generates record BFCM sales, your Rebuy invoice skyrockets to $2,000, $4,000, or even $8,000+ per month. You took the inventory risk, paid the advertising CAC, and fulfilled the orders—why should a software app take a percentage of your gross sales?
Ballooning GMV Revenue Taxes
Paying 0.5% to 2.0% of your gross store revenue on top of expensive monthly base fees penalizes your store for scaling and compresses net operating margins.
Heavy Enterprise JavaScript Bloat
Rebuy's massive multi-purpose client bundle (often exceeding 500KB) drags down mobile PageSpeed scores, increases Interaction to Next Paint (INP), and causes visual stutter on mobile devices.
Missing Native Self-Insurance
Despite charging enterprise rates, Rebuy doesn't include native self-funded shipping protection or priority processing, forcing you to pay for yet another app to capture insurance margin.
Flat SaaS vs. GMV Revenue Share Arithmetic
Let's do the simple math: On $350,000 in monthly GMV, a store using Rebuy pays a $1,500 base tier plus GMV commission fees totaling $2,500 to $4,500 every month ($30,000 to $54,000/year). That same store on Supercart pays a flat monthly tier ($199–$299/mo) with zero commission—saving over $30,000/year. Furthermore, Supercart's built-in self-insurance engine adds another $6,000 to $15,000/mo in pure retained shipping protection margin.
"The 0% GMV Commission Rule: Software is an operational utility, not an equity partner. Never surrender a percentage of your top-line gross merchandise value."
5,000 orders / month ($350k GMV)
$2,850/mo ($34,200/yr) in SaaS fees
Extracted from your brand as fees, third-party cuts, or uncollected opportunities.
$249/mo flat (Save $31,212/yr in app fees alone)
Direct net profit retained inside your business after wholesale replacement COGS.
The Math in Detail: A store doing $250k/mo on Rebuy often pays $1,500–$3,500/month. The same store on Supercart pays $199/mo flat—saving $15,000 to $40,000 per year in pure SaaS app costs.

Frequently Asked Questions About Switching from Rebuy
Clear answers regarding theme compatibility, carrier claims, customer experience, and 0% GMV commission.
Can Supercart replicate Rebuy's AI recommendation rules?
Yes. Supercart supports both smart AI automated recommendations (based on Shopify's native recommendation engine and past purchasing patterns) and granular manual merchandising rules (e.g. 'If Cart contains Product X, recommend Accessory Y; If Cart > $100, show Tier 2 Gift'). You get all the conversion power of smart merchandising without paying Rebuy a percentage of your revenue.
Why does Rebuy charge a percentage of GMV and Supercart does not?
Many venture-backed SaaS apps adopt 'take-rate' or GMV revenue share pricing because it inflates their valuation metrics. At Supercart, we believe software should be priced as a fair, predictable operational utility. We never take a percentage of your revenue. Your growth belongs to you.
Does Supercart support multi-currency and Shopify Plus checkout?
Yes. Supercart natively supports Shopify Markets, multi-currency display, Shopify Plus checkout extensibility, and automated currency conversions for international storefronts.
Will our mobile PageSpeed scores improve after removing Rebuy?
Significantly. Rebuy's client script typically weighs over 450KB and triggers multiple external network requests to third-party endpoints. Supercart weighs ~60KB and runs entirely on native Shopify endpoints, typically improving mobile INP by 80–150ms and boosting Google PageSpeed scores.
Can Supercart help us migrate from Rebuy without downtime?
Yes. Our senior development team provides complimentary white-glove migration. We will configure your recommendation rules, style the drawer to match your exact brand typography, and test checkout on an unpublished theme before you flip the switch.
