Allday Consulting's Peachtree and QuickBooks Support Boards

Can anyone tell me how I can create a report in QB Premier 2007 that shows me, on average, how many days it takes a client to pay an invoice?

I'm working from QBES 8, but the reports should be similar. Reports under Customers & Receivables should have what you're looking for. The A/R graph shows an aggregate of totals owed by aging group; you should be able to filter that for specific clients, but I'm not sure if there are any which show an average across all clients per se. You may need to look into external reporting options, whether it's something as simple as exporting a report to Excel and fiddling with formulae or something as complex as using Crystal Reports.
