Closing your company

Winding down a business: the data steps for your checklist

Your wind-down checklist already covers the final tax return, last payroll, customer notices and the dissolution filing. It almost certainly skips the company's data.

AI companies pay closing businesses to license their email, Slack and files. Here is where those data tasks belong in the shutdown plan.

01

At the start: inventory beside the dissolution filing

In SimpleClosure's experience, asset value falls quickly once a shutdown starts, so it suggests approaching buyers in parallel with the dissolution paperwork. That puts listing the data high on the checklist.

For every workspace, mailbox, shared drive and code repo, record the owner, the years covered, the approximate number of users and any material that must stay inside the company.

02

The data checklist

  • Keep Slack, email, drives and code accounts paid
  • Secure one admin login that outlives the last employee
  • Record peak headcount and the years of records you hold
  • Read vendor contracts, NDAs and privacy policies for limits
  • Flag sensitive files: HR, health, payment data
  • Get two buyer assessments and compare written offers
  • Agree who receives the proceeds under your documents
  • Only then cancel accounts and destroy what is not needed

03

Where it fits with everything else

  • Board approves dissolution

    Approve exploring a data license

  • Notify staff

    Ask key staff to map systems before they leave

  • Cancel vendors

    Keep data-holding tools until a buyer has looked

  • Final tax return

    Confirm record retention with your accountant

  • Distribute remaining assets

    Include data proceeds in the waterfall

Take the match quiz early, while accounts are live. It asks your peak size and what records survive.

FAQ

Questions, answered

When should I start selling data during a wind-down?

At the start, alongside the dissolution filing, while the systems and the people who know them are still around.

What if my board has not decided to close yet?

You can still have a buyer assess the archive. Licensing a copy works for operating companies too.
