- The end date for the contract—For all phases, regardless of the start date for services, the end date for the contract should be the same (or “coterminous”), as depicted below:
If you plan on a phased transition, you must track the date and quantity (by license or service type) of users that move during each phase. You will need this information to verify the accuracy of the billing. It’s much easier to collect this information when you’re already working with it as you prepare to port your numbers. It’s more difficult to go back and recreate the information later.
- Billing should begin when numbers are ported.
- End dates should be coterminous.
- Maintain a record of port dates and quantities (by license or service type) so you can reconcile your bill later.
