Proof-of-payment QR codes

The receipt that proves it — and can't be used twice.

Every paid scan hands your customer a receipt QR. Scan it back at the door and you get one clear answer: PAID, or already redeemed. So a paid ticket, will-call pickup, or entry is verifiable on the spot — no list to check, no “did this one already come through?”

No credit card required to start. Proof of payment is on Starter and up.

How it works

Pay once. Prove it. Redeem once.

01 · Pay

They pay and get a receipt QR

The moment a scan is paid, your customer is handed a receipt QR they can keep on their phone or print — their proof they're good to go.

02 · Prove

You scan it at the door

Scan the receipt back and read a clear answer: PAID and valid, or already redeemed. No guest list, no spreadsheet, no doubt.

03 · Redeem

It marks itself used

Once you let someone in, that receipt reads as redeemed if it's scanned again — so one payment means one entry, every time.

Why proof of payment

No competing QR tool gives you this answer.

Verifiable at the door

A paid order, ticket, or pickup is checkable on the spot — perfect for will-call pickups and paid entry where “did they pay?” needs a real answer.

Can't be reused

Once a receipt is redeemed, scanning it again says so. No screenshots passed around, no double-entry on a single ticket.

No list to keep

You don't check names against a sheet — the receipt itself is the proof. Great for a door, a delivery handoff, or a busy pickup window.

Tied to the sale

Each receipt traces back to the exact payment that earned it, so your records line up end to end — track every scan and what it's worth.

It starts with a paid scan

Proof of payment builds on getting paid by scan: a customer pays, and the receipt QR follows automatically. See how the checkout works on get paid from a scan, or browse everything a code can do.

Proof of payment — questions, answered.

What is a proof-of-payment QR code?

It's a receipt QR your customer gets the moment they pay. Scan it back at the door and you get a clear answer — PAID and valid, or already redeemed — so a paid ticket, order, or pickup is verifiable on the spot.

How do I check that someone actually paid?

You scan their receipt QR with your phone. It reads as paid and valid the first time, and as already redeemed if it's scanned again — so one payment means one entry.

Does proof of payment cost extra?

Proof of payment builds on taking a payment first. Creating codes is free; taking payments and the receipt that comes with them is on the Starter plan and up, with a small per-transaction fee shown on the pricing page.

Where would I use this?

Ticketed events, paid entry, will-call pickups, and deliveries — anywhere you need to confirm a payment in person. See it at a merch table →
