# Why can't I change a sent invoice's amount?

Financial edits are available on drafts; posted invoices have a limited details form.

Only drafts allow changes to customer, dates, lines and amounts. Opening full edit for a paid or otherwise noneditable invoice returns to its details with a message. With Edit invoices permission, **Edit Details** on a posted invoice changes nonfinancial details such as reference, addresses and wording. A void invoice cannot use that form. Correcting financial amounts requires reviewing the appropriate void or payment correction, rather than editing the posted lines. Follow [Edit, void or delete an invoice](https://demo.qixcount.com/help/invoicing/edit-void-or-delete-an-invoice) before changing a record with payments.
