How to make a copy of your draft invoice before sending it

This copy is very useful if your invoice generates an error or if the invoice is for certifications and contains the same items each month. In the event of an error or if the invoice is rejected, just select the saved draft and select “edit”.

Once you are in the totals, you must return to drafts before sending.
Your invoice line will be displayed, and you will have to click on the magnifying glass
Then click “copy” to display a screen where you have to enter the invoice number (add-copy) and date, and click on “copy invoice”
Finally, go back to drafts where both are displayed. Click on the magnifying glass in the original, select edit and next on all the screens until sending at the end.
