Hi all,how do i ammend an existing sales invoice?

Hello Pjbrownefc, Thanks for getting in touch with the Community! You can go to sales>customers>select customer and then click on the line of the invoice and it will take you into it and then you can edit any information and save and close in the bottom right. You can also use the magnifying glass symbol in the top right of QuickBooks to search the amount or customer name as a quick search to find the invoice.
