We have an issue where some of our invoices are subject to retention and I don't find out the details until after a short payment has been made. I need to be able to do two things"
1. Record internal notes, however if I use the Comments field and don't print on invoice templates, I have read that it is a sticky field so next time I raise an invoice, the previous comment will be there, which has nothing to do with a new sale.
2. Record the new due date for the balance. Is the only way to do that so it doesn't show up as overdue in the ageing reports, or disappear off my outstanding invoice list altogether, by changing the terms on the invoice to reflect the balance due date? I looked at the recommended approach of creating a liability account, entering the retention on the invoice as a negative posted to the new account etc. but that means I need a whole new due date tracking mechanism.
