The checkout that takes over your Shopify store, pays out through your own Whop, and never touches a card number.
Built by an operator running real Shopify stores — I shipped Onyx for my own checkout first, because I was sick of processors freezing my money. Not a fintech that's never run ads.
Every scaling store hits the same wall: the sales work, but the cash is held hostage. Reserves, rolling holds, and surprise bans turn a growing business into a cash-flow emergency.
Your cash sits locked in a processor's "reserve" while your ad spend keeps draining. You can't scale on money you can't touch.
A 10–20% "rolling reserve" quietly chokes your cash flow — right when you're scaling and need every dollar working.
One sales spike or a few chargebacks and your account's gone — with nothing but a support ticket to show for it.
Legacy processors park your revenue in reserves and rolling holds. Onyx settles through your own Whop — in your account the same day.
Drag the sliders to your numbers. This is the cash regular processors keep sitting in holds and reserves — money Onyx puts back in your account the same day.
Three steps from frozen payouts to cash in your account. Your store never changes.
Connect Onyx to your Shopify store in a couple clicks — just like installing any app. No code, no theme edits, nothing on your storefront changes.
Your customers tap the same “Check out” button. It just opens your own faster, branded checkout — with upsells, a timer and trust badges built in.
The money lands in your own Whop account in minutes — not frozen for weeks. The paid order drops back into Shopify automatically, so shipping works like always.
Get set up in minutes with guided onboarding — connect Shopify, connect Whop, go live. Stuck on something? A real person helps you set it up — not a bot and a queue.
Conversion tools Shopify's checkout won't give you, wired to a processor that actually releases your money.
Drag-and-drop blocks — reviews, trust badges, a guarantee, a countdown timer. No code. Matches your store and goes live in minutes.
Add one-tap order bumps and upsells right on the checkout — extra profit on every order that Shopify's default checkout just can't do.
Subscribe & Save, free trials, and automatic retries when a card fails — so you keep the recurring money. Customers manage it themselves.
Send a slice of your buyers to your Onyx checkout and the rest to Shopify's. Watch the results side by side and flip it off any time.
Your Meta and TikTok tracking keeps firing accurately — even with iOS updates and ad-blockers — so your ads keep learning and scaling.
Refund an order once and it's handled everywhere — no jumping between tabs, no mess to clean up later.
Checkout runs on your own link with your logo — buyers never feel like they left your store, so trust stays high through the sale.
Live sales, conversion, recurring revenue and dispute alerts — the numbers that actually matter, all in one place.
The second someone pays, the order lands in Shopify and in Onyx — with upsells, your tracking and payouts, all in one place.
Every renewal runs through your own Whop, and if a card gets declined we retry it automatically — so one bad bank day doesn't cost you the customer. Watch your recurring revenue and cancels live.
Some "takeover checkouts" quietly grab card data. Onyx is built the opposite way — card details go straight into a secure, bank-level card box and never reach us at all.
Free for your first month. After that, a small slice of sales — no monthly fee, no lock-in, no hidden reserves. Card processing stays at your own Whop rate; Onyx just powers the checkout.
Everything you need to launch a faster checkout — on us for your first 30 days.
After your free month, you only pay when you actually get paid. No monthly fee.
Founding partners and high-volume stores — custom, better terms.
Nope. Your Shopify store, theme, products and apps stay exactly the same. Onyx just swaps the checkout step — you're basically adding an app. Nothing on your storefront changes.
Yours. Payments run through your own Whop account (that's your payout account, and it actually pays fast). You hold the money — not us. We can't touch it or freeze it.
Minutes to a day, through Whop — instead of the weeks-long holds and reserves normal processors hit you with right when you're scaling. You can even pull it to crypto the same day.
Totally safe. Card details go into a secure, bank-level card box — the same kind of tech Stripe uses. Card numbers never touch Onyx, so you're never holding risky data.
If you can install a Shopify app, you can set up Onyx. It's a few clicks and a short checklist — connect Shopify, connect your payout account, hit go. Most stores are live the same afternoon.
They tap the same “Check out” button and land on a clean, fast checkout with your logo and colors — usually it converts better, not worse. If anything ever fails to load, it quietly falls back to your normal Shopify checkout.
You never lose the sale. If our checkout can't load for any reason, the buyer goes straight to your normal Shopify checkout automatically. It's built to fail safe.
Swap your checkout, keep your store, and get paid in minutes through your own Whop. Set up in an afternoon.
