Yeah one more demand for this feature. When you manually accept a payment outside Shopify (eg someone sends a wire transfer, as many of our international customers do for big orders) there’s nothing forcing it to be the exact same amount that’s outstanding. If a customer accidentally over or under pays, that needs to be able to be fixed in Shopify by specifying not just that “payment was collected” but by specifying the amount of payment that was collected.
Not “it should be able to”, it NEEDS to be able to because there isn’t another way to fix it that actually reconciles with a bank account.
