Thanks for your reply.
Yes I can see that, however it doesn't tell you 'at a glance' the number of days that an invoice is overdue (as it used to) in the invoice tab.
It was really useful as the oldest invoices and most overdue were at the top. I'm currently seeing that an invoice is overdue and having to count the days on my fingers before emailing customers to remind them!!
Thanks for that Hads76, we have taken this feedback on board and will pass it onto the development team, you can also leave feedback in the main cogwheel which also gets sent straight to the developers.
