Shopify’s enterprise plan
Onyx vs Shopify Plus
Below Plus, the checkout is the one page Shopify will not let you change. That is not an oversight — it is what Plus is sold on.
Onyx solves the checkout half on its own: your page, your domain, your offers, on the plan you already pay for.
| Shopify Plus | Onyx Checkout | |
|---|---|---|
| Edit the checkout page | Plus only | Any Shopify plan |
| Entry price | From about $2,300 / month | $79 / month per store |
| Order bump inside the checkout | Custom development | Built in |
| Post-purchase offer on the same order | Apps or custom work | Built in |
| Server-side purchase events | Custom pixel work | Five platforms, built in |
| Contract | Usually annual | Monthly, cancel any time |
Figures from each provider’s published pricing, checked September 2026. Everything in the Onyx column is in the product today. Card processing is charged by your payments account in every case, including ours.
On your numbers, not on an example.
Drag your monthly revenue across. Every figure is the monthly cost of the checkout itself — what the card processor charges is separate, and you pay it either way.

When Shopify Plus is the right answer
Plus earns its price when you need B2B wholesale channels, dedicated infrastructure for flash sales, several storefronts on one contract or a named account team. Onyx does none of that — it does the checkout, on any plan.
