- 01
Stand up recurring invoicing
Run the first month in parallel with manual. Validate every invoice against the manual ledger before cutover.
- 02
Automate dunning
Define grace periods, reminder cadences, and suspension rules. Document the operator escalation path before flipping the switch.
- 03
Wire multi-jurisdiction tax compliance
Telecom tax is its own discipline. Use a system that handles US states + Canadian provinces if you operate in both.
- 04
Embed payments and self-service
Subscribers pay through your portal, not by calling the office. Reduces ticket volume and lifts NPS in the same release.
Manual billing breaks at 1,500 subscribers. The phone rings during invoice runs, proration disputes eat the help desk, and the monthly close drags into week two. The fix is not faster spreadsheets. The fix is automation that runs in the background while operations runs in the foreground.
This playbook walks the migration. What to automate first, what to automate last, and what to leave manual on purpose.
Questions, answered.
When should I automate billing?+
When manual close pushes past day 7 of the month, or when one billing person is doing the work that should be split across two roles. Most ISPs hit this between 1,200 and 1,800 subscribers.
Will this break my CSR workflow?+
Run automation in parallel for one full billing cycle before cutover. Validate every invoice. The CSR team gains hours back once the migration completes.
