🧾 CheckoutWorks

Design the order bump and one-click upsell stack that bolts onto any store or funnel — and raise every order above its sticker price.

ThriveCart charges $495 one-time for this. CheckoutWorks is $149 once, yours forever, no meters, no monthly rent.

Honest note: CheckoutWorks designs and tracks your checkout stack. It does not take payments and never charges a card. The actual charge runs on your own checkout — Stripe, your cart, or your funnel tool — using the stack sheet you export from here. No fake checkout, no fake payment, ever.

Your stacks

Everything is saved on this device automatically. No account, no sign-in — just build. Pick a stack to work on it below.

1 · Your products

The products you sell. The builder pairs them by price: a good order bump costs about 30–50% of the main product, and a good one-click upsell costs about the same as the main product, up to 2× it.

New product name Price ($)

2 · Build the stack

Choose the main product a buyer came for. CheckoutWorks ranks every other product as a bump or upsell by price fit, writes the copy, and previews exactly what the buyer sees.

Main product — what the buyer clicked “buy” on

↓ then, on the checkout page ↓

🟡 Order bump — one checkbox on the checkout page, ~30–50% of main price

Bump product

Bump headline — editable; regenerate any time Bump copy

↓ after they pay, one click ↓

🟣 One-click upsell — offered right after payment, no re-entering the card, ~1×–2× main price

Upsell product

Upsell headline — editable; regenerate any time Upsell copy

3 · Buyer view — what they actually see

A plain preview of the stack, in order, with the total math shown every way a buyer can take it. This is a preview only — it takes no payment.

Your order

Total math — every path

4 · Take-rate log

After orders run on your own checkout, log the counts here (from your Stripe / cart reports). Take-rates and average order value update live — this is how you know if a pairing is earning its slot.

Export the stack sheet

One document with the whole stack — products, order, prices, the bump and upsell copy word-for-word, the total math, and your take-rate numbers. Hand it to your checkout tool (Stripe, cart, or funnel builder) and set the stack up exactly as written.
