Ok so I have an idea so it doesnt affect my prior year numbers... redo the invoice with the new customer name and print it without posting ... that way when they pay I can apply the payment against the old customer (original invoice) with a note stating who paid.  This way the client is happy as he has an Invoice with his name on it and I'm happy as it's not affecting my prior years income... do you see a problem in this idea?

If you have check for duplicates on invoice numbers turned on then you will get a message.  If you print using a different invoice number, you will lose that number and have to reset it (might only happen in multi-user mode).

Personally I would consider reversing the original in this year, then posting the new one under the new name.

The easiest way to do this is

1. lookup the old invoice
2. store it as a recurring transaction
3. recall the recurring transaction
4. change the quantities to a negative without affecting anything else - just put a negative sign in front
5. if the original invoice was numbered 2500 then I would use Rev2500 as the new invoice number and today's date
6. make sure the journal entry is the same but in reverse (all debits now credits etc. when compared to the original invoice)
7. add a comment on the last line in the description column that explains what is going on
8. post
9. recall the recurring transaction again
10. use today's date and the next invoice number in sequence or the old invoice number if you like
11. change the customer
12. make sure the journal entry is the same as the original invoice
13. print and post
14. remove the recurring transaction
15. open Receipts and select the old customer
16. pay the positive invoice against the negative invoice using a receipt number like Rev2500 and today's date
17. post

easy as 1, 2, 3.....17!

There should be no affect on the books this year in any account if the above goes smoothly.

the client now wants me to resubmit it to a different client name

Another way to do this is:

Change the company name in the Customer ledger

Print the invoice with the different client name.

Change the company name back again, if this is not a permanent change.

Apply the payment to the 'old' company name.

Or,

Print invoice to PDF / Email to yourself,

Edit in Adobe Acrobat or some other PDF editor
