Closing a Customer Account Cleanly Across Four Teams

The Starting Point

A cancelled account touches several teams. Engineering has the service, accounting has the billing, the number is in the inventory, and the number has an emergency address registered to it. If one team is missed, the account is only partly closed.

What I Did

I worked through the company's cancellation checklist across engineering, accounting, number inventory and E911, and checked each step was done before moving on.

Billing was stopped without a final invoice going out. The number was released from the inventory, and the records were closed.

I documented every step, so anyone looking at the account later can see what was done and when.

What the Checklist Covered

Why It Matters

If one team is missed, a customer who has left can still get an invoice, the number cannot be given to anyone else, or an emergency address stays registered to a number that is no longer in use.

I ran one checklist across all four teams and wrote each step down, so nothing about the account needs to be closed again later.

Tools and Skills Used

Customer offboarding, cross-team coordination, billing records, number management and documentation.

Who This Is For

This case study is worth reading if you are:

• ●A business where cancellations are handled by several teams and something often gets missed.
• ●A telecom or subscription business that still bills customers after they have left.
• ●Looking for someone who works from a checklist and leaves a clear record behind.
