Invoices

An Invoice is a bill you send a customer, made of line items (usually referencing a Product/Price), that gets finalized and then paid.

How it works

Create a draft Invoice for a customer and add line items — each can reference a product/price, and the invoice can carry a coupon, tax rates, and fees.
Finalize it once the line items are correct — this locks the amount and makes it payable.
The customer pays it (directly, via Checkout, or via a Payment Link), which creates a Charge.
If something needs correcting afterward — a partial refund, a pricing mistake — issue a Credit Note rather than editing the paid invoice.
Retrieve an Invoice, or list every Invoice.

A draft invoice can still be edited or deleted. A finalized one can't be changed — only voided (before payment) or credited (after payment).
