What the template tracks

Customer details

Name, reminder email, and phone number stay together.

Next due date

Sort by date to see overdue tests and the next month of work.

Repeat value

Estimate the revenue represented by upcoming renewals.

A spreadsheet is a good starting point

The City of Raleigh, for example, requires testable assemblies in higher-risk services to be tested by a certified tester and publishes both a testing schedule and a certified-tester directory. Requirements vary by water authority, so verify every due date locally. The hard part for a service business is following up reliably once the customer list grows.
