The operational reality
A growing accountancy practice can carry hundreds of clients on fixed monthly fees. Each one has its own agreed fee, payment day, renewal date and a running list of ad hoc work: a VAT query, a payroll correction, a meeting with HMRC, a set of management accounts done at short notice.
None of that lived in one place. Agreed fees sat in a spreadsheet, engagement letters in a shared drive, ad hoc requests in email threads and the actual invoices in QuickBooks. To answer a simple question such as “has every client been billed correctly this month?”, someone had to open all four and check each client by hand.
