Anyone know if it's possible to add comments to either an invoice or the slips that make up the invoice after it's been created? I'd like to go back and add some information to a couple of invoices for my own future reference.

Hi Mark

It appears as though you can double-click the invoice in the Account Status tab and add more comments in the window that opens. Initially, those comments reflect the comments on the PDF invoice but can be altered.

HTH,
