For operators past the point where Shopify pays back — B2B pricing, vendor splits, custom checkout, real inventory rules. The margin Shopify charges per-app for, folded back into a codebase you own.
What you get
Custom attributes and variant logic modelled properly, not bolted onto a theme.
Stock holds, multi-warehouse, low-stock thresholds — built on signed webhooks, audited per attempt.
Single-page, multi-step, or B2B quote flow — whatever your buyers actually need.
Retry, dunning and webhook reconciliation. The billing event is the source of truth, not a polling job.
How it runs
The same stages run every engagement. The service decides the scale, not the method.

Shopify is right until your pricing logic is. B2B tiered pricing, configure-price-quote, bundled SKUs, custom checkout flow — custom builds the rules into the data model. You own the cart, the checkout, the customer record. App-store rent stops.
Yes. Products, variants, customers, order history, subscriptions, reviews — pulled via API, mapped into the new schema, reconciled before cutover. SEO redirects preserved. The migration runs in shadow until you're satisfied, then DNS flips.
Per-customer price lists, volume breaks, contract pricing, MOQ rules, region multipliers. Encoded in the data model, not hard-coded in checkout. Audit log on every price change.
Stripe Tax for automated VAT, sales tax and GST across jurisdictions. Multi-currency with daily rate refresh. Picked on the call against your jurisdictions, not assumed.
You. Your repo, your Stripe, your Supabase, your domain. No Canarlo SaaS, no licence fees, no app-store rent. The handover names every cron, every webhook, every environment variable.
