Find the invoice in QuickBooks Online and open it to view its current details.

02Update invoice details

Adjust customer information, line items, or dates as needed to reflect the correct billing details.

03Adjust item quantities and pricing

Change quantities, rates, or add discounts so the invoice total accurately reflects what's owed.

Confirm your edits and save the invoice so the changes are reflected in your records and any linked reports.

If the invoice was already sent, resend the corrected version so the customer has the accurate copy.

FAQ

Frequently asked questions

Can I edit an invoice after it's been sent to a customer?

Yes, you can still edit it in QuickBooks Online, but you should resend the updated version so the customer has accurate information.

What happens if I edit an invoice that's already been paid?

Editing a paid invoice can create mismatches between the payment and the new total, so it's best to review payments before making changes.

Can I add a discount to an existing invoice?

Yes, QuickBooks Online lets you add discounts directly to invoice line items or the total when editing.

Does editing an invoice affect my inventory records?

If the invoice includes tracked inventory items, changing quantities can affect your inventory counts, so it's worth double-checking those numbers.
