Get help with an invoice or payment

Questions about the work or amount

Contact the business that sent your invoice if you need to correct the work description, amount, due date, or customer details. That business can explain the invoice and arrange any changes.

Trouble opening an invoice

Open the full link from the original message. If it no longer works, ask the sender for the current invoice link.

Trouble completing a payment

Note the exact message shown on the payment page. If you aren't sure whether a payment completed, check for a confirmation and contact the invoice sender before trying again.
