I have one supplier that has over 100 invoices each month. Firstly it takes forever to find all the invoices due to the date order in Batch Payments, and then when I have ticked all the invoices, to then find I have selected over 100 and have to start all over again is extremely infuriating. A flag or notification to let the user know they have chosen 100 invoices and can't select any more would be much appreciated.
I couldn't believe this restriction when it first happened to me - I had spent for-f***ng-ever paging down through a years worth of invoices to get back to April-16, then about another half an hour ticking 256 invoices for payment (with a single cheque) to then be greeted with this diabolical message. It's like the software is not designed for medium sized businesses. This area of Kashflow needs some serious attention.
