Pre-fill the invoice number and amount

You can fill in the invoice number and amount on the payment page for your customer. Each invoice has its own number and amount, so you do this for each link you send.

Add this to the end of your payment link:

?id=1002&amount=1.00

So a link ending in /invoice becomes:

<your payment link>/invoice?id=1002&amount=1.00

1. Replace 1002 with the invoice number.
2. Replace 1.00 with the amount.
3. Open the link to check it, then send it to your customer by email or any other way.

You can fill in just one of them. For example, for the invoice number only:

<your payment link>/invoice?id=1002
