Invoices that chase themselves

Overdue invoices chase themselves. Every invoice that falls due is read, a reminder is written and sent, and the chase repeats on the schedule you set until the money arrives. Paid invoices file themselves away, and anything still unpaid after your limit goes to a person rather than another email.

You set the rules

How long to wait between chases, and how many days of silence before a person is brought in, are yours to set. The wording is yours too.

What changes

Three things it changes.

Nobody keeps a chase list

Due dates and amounts are read from the invoices themselves, so there is no spreadsheet of who to nudge and when.

The reminder goes out on time

The first one the day an invoice falls due, then again on your schedule, in the same words every time.

It stops when it should

A paid invoice files itself and the chasing ends. Anything still unpaid after your limit goes to a person, not another email.

90%*Less time spent chasing
Day 1*First reminder, every time
3 weeks*Of work back each year

* Estimated from a conservative model of 100 invoices a month, 40 of them paid late, not measured results. The percentage covers chasing and logging, not the rest of the bookkeeping, and the first reminder goes out on day one of the schedule you set. The assumptions behind these figures are available on request.
