Why was my invoice rejected?

You can review the reason your invoice was rejected in the email notification from your customer. If you need further clarification, contact your customer.

After your invoice is rejected, you need to submit a corrected invoice so your customer can process it for payment. Depending on your customer's invoicing rules, you might be able to reuse the invoice number from your rejected invoice. If not, you'll need to choose a unique invoice number when submitting the corrected invoice.
