WHAT TO ESTABLISH FIRST
What data exists How to export it, and in what format What it costs to move out What depends on the service
WHAT TO DO IN ORDER

WHY IN THAT ORDER
Cancelling first loses access and frequently loses the data.
THE RETENTION POINT
Data is typically deleted after a period once you cancel.
Establish that period before cancelling.
WHAT TO CHECK BEFORE CANCELLING
That you have everything That it opens and is usable That nothing still depends on the service
WHAT TO REMOVE
Integrations pointing at it Credentials and keys References in documentation
WHAT TO KEEP
Your exported data and your final invoices.
