Individual customer activity report with payment history
When customers are querying whether they have overpaid you, you need to be able to print off an activity report for that customer to show them all paid invoices and dates/amounts of payments received. With large, ongoing projects, some clients make random payments on account and it can get confusing. Seems a basic requirement and I don't how how to get around this. It doesn't sound very professional to say that our accounts software cannot generate such a report.
