Invoices are structured payment requests you send to customers. Each invoice generates a unique checkout link where the customer can pay using any active gateway. Invoices differ from payment links because they carry line items, a due date, and a formal invoice number.
How invoices relate to payment links
When you create an invoice, OwnPay generates a payment link behind the scenes. The customer clicks the invoice link, sees the itemized total, and completes payment through the checkout. You can also create standalone payment links without line items - see Payment links.
Create an invoice
- Go to Payments → Invoices.
- Click + Create Invoice.
- Fill in the invoice details (see table below).
- Add one or more line items with a description, quantity, and unit price.
- Click Create Invoice.
Invoice statuses
Generate invoice PDFs
Open an invoice and click Download PDF to get a formatted receipt. The PDF includes your brand logo, the customer’s details, all line items, the total amount, and the payment status. Use this for accounting records or to email to the customer as a receipt.
Send invoices via email
Click Send via Email on any invoice in Sent or Draft status. OwnPay sends the customer an email with the invoice details and the payment link. The email uses your brand’s SMTP configuration and support email as the sender.
Invoice numbering
OwnPay does not auto-increment invoice numbers. You set the number manually when you create each invoice. This gives you flexibility to match your existing accounting system (for example INV-2025-0042, REC-0042, or any format you prefer).
Every invoice must have at least one line item with a quantity and unit price greater than zero. An invoice with no line items or a total of 0.00 cannot be paid.
