How do I change the income account on a paid invoice? Is there an easy way to do change multiple invoices?

Hello @adoriable ,

The income account used on your invoices is associated to the product or service item that has been used on the invoice.  So you would have to go in to the product/service item and edit the income account linked to each item you have invoiced someone for.

Unfortunately, that will only affect future invoice transactions.  All your existing invoice transactions will remain in the old income account.  The only way to fix this is to edit each, individual invoice; delete the product/service item line you used originally, and re-enter the product/service so that it will pick up the new income account you associated with it.  If you are going to go this route, I would suggest that you add the new lines before deleting the old lines, to make sure that all of the details (item, description, amount & taxes) are identical to what you originally entered.  Once your duplicate lines are good, then delete the old lines.

Another option would be to make the necessary change to your product/service items and use the new account on all invoices going forward; then simply make a lump sum journal entry to move the $ amount of sales from the undesirable income account to the new income account.  That way, although the details in the old invoices won't be linked to the correct income account, your P & L will be correct.  In fact, if you run regular financial reporting on a monthly basis, you might want to calculate the amount of sales in the wrong account for each month, and make a monthly JE to transfer sales from old to new account, dated the last day of each month.
