How to Write a Vendor Exit Plan with AI (2026): The Data, the Date, the Owner

A vendor exit plan written with AI is a page that says what data comes back, by which date, who owns each step, and what happens if the export fails. The model may format rows you paste. It may not invent a contract clause, a retention promise, or a migration date. The risk note that should exist before you decide to leave is how to write a dependency risk note with AI. The cutover itself is how to write a migration runbook with AI.

How long the vendor may keep prompts and files after you leave is what an AI data retention policy is. The backout if the new tool fails in the first week is how to create a rollback plan with AI.

What belongs on the plan

Row	Who owns it	The model may
The data	The system owner	List the exports you named. It may not add a dataset
The date	The contract or the notice you already sent	Copy it. It may not pick a “safe” date
The owner	A person you named	Copy the name. If the name is missing, stop
The access	Who loses a login, and when	Format it. It may not leave a shared admin “for later”
The failure	What you do if the export is incomplete	Copy the fallback you wrote

A plan that says “export everything and move on” is not a plan. Name the objects: prompts and logs, customer records, files, billing history, SSO apps, and the admin who can still sign in on the last day. If counsel has not read the termination clause, the date cell says Counsel missing.

Where the plan is written

The draft. Claude Pro is $20 a month, or $17 billed annually, when the plan is long and should sit beside the contract notes you are allowed to paste. Paste clause text you are allowed to share. Do not paste a full agreement into a personal account your company forbids. The review is Claude review.

The page procurement already uses. Notion AI Business is $20 a seat a month if that is the system of record. The chat is not the plan.

The checklist in the repo. Cursor Plus is $8 a month, or $80 a year, when the exit includes scripts that pull an export. You review the diff. A generated script that prints secrets into a log is a defect. The ladder is Cursor pricing explained.

A one-page version. ChatGPT Plus at $20 a month can format a short plan. Discard any row it adds because every exit “should include a press release.”

A prompt that holds the line:

“Format an exit plan from the data sets, dates, owners, and fallback I pasted. Do not add a data set. Do not invent a notice period. If an owner is missing, write Owner missing and stop.”

What not to delegate

Do not ask the model whether you are allowed to leave. That is the contract and counsel. Do not announce the exit to customers from this page. Customer language is a separate note, after the plan has owners. Do not delete the only admin on the vendor side before the export is checked by a person.

FAQ

How is an exit plan different from a migration runbook?

The exit plan is what you must retrieve and who turns access off. The runbook is how the new system gets the data and how you back out. The runbook should point at this plan. If they name different dates, one of them is wrong.

Can the model read the contract?

Only the clauses you paste and are allowed to paste. A summary that adds a termination right you cannot find in the paste is the sentence you delete. Counsel reads the real agreement.

What if the vendor will not export?

That case is the fallback row, written before you give notice, not a surprise on the last day. The plan says who calls, what you can still download from the product, and what you will tell customers if a copy does not exist.

Who signs the plan?

The owner of the vendor relationship and the owner of the data. A model does not sign. A page with no names is a draft.
