Picture a three-person bookkeeping practice looking after roughly 120 small-business clients, with the same bottleneck every month. Before anything can be reconciled, the records have to come in: bank statements, receipts, the odd invoice. Most clients send them eventually. Getting there is the problem.
One team member spent the better part of a day each week working a spreadsheet of who still owed what, writing individual reminder emails, remembering who had already been asked twice, and deciding who needed a phone call. The reminders were easy to forget when the week got busy, so month-end always ran late, and the same handful of slow clients held everything up.
