The rule is one sentence: on the Pro plan, an order is charged $0.04 the first time we verify its shipping address, and never again. Everything below is that rule applied to the edge cases merchants actually ask about.
One order, one charge, always
An address can get checked more than once. The buyer revisits the order status page, edits their address, or an express checkout hits both surfaces. None of that bills twice. The ledger is keyed by order, not by check, so re-checks of the same order are free by construction.
This matters most for Shop Pay, Apple Pay, and Google Pay orders, which can trigger verification on the thank-you page and the Order Status page, and that’s still a single charge.
Yes, a correct address counts
If we verify an address and it comes back clean, that order is still charged. The verification is the work: a clean result is the lookup telling you the parcel will arrive, not the absence of a lookup. Every per-order validation app works this way. The difference we can offer is visibility, which is the next section.
What never gets charged
- Your first 100 orders. The lifetime free trial comes off the top before any billing starts.
- Orders with no shipping address. A buyer who abandons checkout before entering an address never creates a charge.
- Orders we couldn’t verify. If the verification service is ever unreachable, the order goes through untouched and tagged. It is not billed, and it doesn’t use up a free-trial slot either. You don’t pay for work that didn’t happen.
- Anything on Free. Free has no charges of any kind, because Free makes no verification lookups.
- Buyer corrections. When a buyer applies or edits a fix, that re-verification rides on the order’s original charge.
In-checkout correction changes the unit to the checkout (Shopify Plus)
Plus stores can turn on in-checkout correction on the app’s Verification page: the suggested fix appears inside checkout, before the order exists. Verification then happens the moment the buyer finishes entering an address, so the charge attaches to the checkout instead of the order. It’s still $0.04, charged once per checkout, however many times the buyer edits the address. When the checkout becomes an order, that’s the order’s charge; the thank-you page re-check rides on it.
The honest part: a buyer who enters a full address and then walks away was still verified, and that checkout is still charged. Your Billing page labels those rows “Abandoned checkout” so you can count them yourself, and they use free-trial slots like any other verification. With in-checkout correction off, none of this applies and abandoned checkouts never bill.
Where you see the charges
You see them in two places. The Plan card on your Address Verifier home screen shows “N orders charged · $X” for the last 30 days, so the running cost is visible inside the app, not just on a bill weeks later. And the actual charge lands on your regular Shopify invoice, since all billing runs through Shopify. We never touch your payment details.
During plan approval, Shopify will show a $500 monthly maximum on the Pro plan. That’s a required safety ceiling on usage billing, not a fee. Switching plans explains it.
