Odd one - and it may not be a Quickfile issue, but I cannot easily create PDF invoices within Quickfile. It might be a Firefox/Windows issue - but I thought I would just put it out there to see if anyone else has the same issue.
The way around it is to use the Windows Printing/Save to PDF - so when I select Print on the invoice creation page, I then have to select Print from within Firefox to bring up the Windows print page, and Print to PDF that way. Not a disaster, but an extra step I didn’t have until last week.
