How to pay an invoice

By Diljit Ramachandran, founder of The Invoice Generator. Published Oct 26, 2026.

To pay an invoice, check that it is correct and matches what you ordered, use the payment details on it, pay by the due date, and keep a record of the payment. Ask the seller for a receipt if you need proof.

What are the steps?

Paying an invoice means settling a seller's bill: confirming it is correct, then sending the exact amount by the due date to the account on it.

  1. Check the amount, the items and the invoice number.
  2. Match it to the order, quote or PO number.
  3. Look at the payment terms for the due date.
  4. Pay by the method shown: bank transfer, payment link, card or paper check.
  5. Keep the confirmation, and ask for a receipt if you need one.

What if something is wrong?

Contact the seller before the due date. They may issue a credit note or a corrected invoice. Query the error before you pay. If only part is wrong, ask whether you can pay the undisputed amount now. Paying a wrong amount and fixing it later can leave you out of pocket.

Questions

How do I pay an invoice online?
Use the link or bank details on the invoice. Check them against earlier invoices from the same seller. If the account has changed, confirm it with the seller by phone, using a number you already have, before paying.
Do I need to keep invoices I have paid?
Yes, with the proof of payment, for as long as the rules for your records say.
