How to fire your marketing agency without losing everything

This post is against our interest, which is the point

We sell marketing services. Writing a guide to leaving a marketing agency is not an obvious business decision. We’re doing it because the same conversation keeps happening, and it goes like this: someone wants to move their work to us, and halfway through the handover we find they don’t own their own advertising account, or their website, or in one case their domain name.

At that point the leverage has already been lost. The old vendor holds something the client needs, and the client discovers it in the worst week to discover it.

So here is the version we would want a friend to read — including the parts that make leaving us straightforward, because a client who can leave easily and stays anyway is the only kind worth having.

Do this before you send the email

The single biggest mistake is telling the agency you’re leaving before you’ve confirmed what you control. Notice changes the relationship. Access requests that took an hour to fulfill last month can take three weeks after the notice email, and nobody is technically doing anything wrong.

Spend an evening auditing access first. Log in to everything yourself. Where you can’t log in, find out whose name is on the account. Then give notice.

The domain is the one that ends careers

Your domain name is the foundation of everything else — your website, your email, every link anyone has ever shared. If it’s registered in the agency’s name, or in the personal account of a developer you used in 2019, you do not own your business’s address.

Check it today. Look up your domain in a public WHOIS lookup, then confirm you can actually sign in to the registrar account it lives in. Being listed as the contact is not the same as controlling the account. If it’s not yours, ask for a transfer while everyone is still friendly. That request is normal, it’s cheap, and it costs you nothing to make it now.

Ad accounts and the Business Profile are what people discover too late

Here is the specific warning, because these two catch more owners than everything else combined.

If your agency created your Google Ads or Meta ads account inside their own business manager, the account belongs to them, not to you. You can be removed from it. And what leaves with it is not just the ability to run ads — it’s the conversion history, the audiences you built, the years of learning that make an account cheaper to run than a fresh one. Starting over on a new account is a real, measurable setback, and it’s invisible until the day it happens.

The Google Business Profile is the other one. It’s the listing that shows your hours, your photos, and every review a customer ever left you. If the agency holds the primary ownership on that profile, they hold your reviews. Reviews are not portable. You cannot rebuild seven years of them, and no amount of goodwill gets them back if the relationship ends badly.

The fix in both cases is ownership, not access. You want to be the owner of the account, with the agency added as a user. Not the other way round.

• Google Ads — you own the account; the agency is linked as a manager and can be unlinked.
• Meta Business Manager — your business owns the ad account and the page; the agency has partner access.
• Google Business Profile — you hold primary ownership; the agency is a manager.
• Google Analytics and Search Console — the property lives in your account, with the agency granted access.

Your CRM data and your list are yours — get them out anyway

Contracts usually say the data is yours. That’s true and it’s not the point. The question is whether you can get it out in a usable form after the account is switched off, and whether you know what "all of it" includes.

Export the contact records with every custom field, not just names and emails. Export the notes and the activity history, because that’s where the context lives — who called, what they asked, why the deal stalled. Export the pipeline stages. And export the unsubscribe and bounce lists, because mailing someone who opted out after you switch platforms is how a good sender reputation dies in one send.

Do the export yourself, open the file, and check it has rows in it. A zero-byte CSV that arrived on time is still nothing.

The creative files, not just the finished PDFs

A finished PDF is a photograph of your marketing. The source file is the thing you can edit next year.

Ask for the working files: the layout documents, the logo in vector format, the fonts you’re licensed to use, the raw photography, the email templates, and the copy in an editable document. Whether the agency is contractually obliged to hand these over depends on your agreement, so read it — but ask regardless, because most will say yes when asked politely and no when asked angrily.

The vector logo is the one to check first. If the only version of your logo anywhere is a low-resolution image lifted from your own website, the next person you hire has to redraw it before they can print anything.

The website is usually more tangled than you think

Three separate things get confused here: who owns the code or the content, who controls the hosting account, and who controls the platform login. You can own one and not the others.

Find out where the site is hosted and whose card pays for it. Get an admin login you created yourself, not one shared with you. Take a full backup — files and database — and keep a copy somewhere that isn’t the hosting account. If the site was built on a proprietary platform the agency licenses, understand now that you may not be able to take it with you at all, and price a rebuild into your decision rather than finding out in week two.

The checklist

Work through this before giving notice. It’s an evening of clicking, and it’s the cheapest insurance in this article.

1. Domain — confirm you can sign in to the registrar and that the account is in your business name.
2. Business email — confirm you are a super administrator, not just a mailbox user.
3. Website — admin login you created, hosting account access, full backup downloaded and stored elsewhere.
4. Google Business Profile — confirm you hold primary ownership.
5. Google Ads and Meta — confirm the accounts sit in your business, not the agency’s, and note the account IDs.
6. Analytics and Search Console — confirm the property is in your account.
7. CRM — export contacts with custom fields, notes, pipeline stages, and unsubscribe and bounce lists. Open the files.
8. Email platform — export subscribers, segments, suppression lists and the templates.
9. Creative — vector logo, layout source files, photography, editable copy.
10. Billing — find every subscription paid by the agency on your behalf, and move them to your card before, not after.
11. Read the contract for the notice period and any clause about work in progress.
12. Only now: send the notice, in writing, with a clear last day.

How to give the notice

In writing, brief, no autopsy. You don’t owe a detailed explanation and offering one usually starts a negotiation you didn’t want. State the last day of service, ask for a handover of the specific items on your list by that date, and thank them.

Honor the notice period and pay the final invoice on time. It costs nothing and it keeps the handover cooperative, which is worth more than the last month’s fee.

And schedule the overlap. Do not switch off the old vendor on the thirty-first and start the new one on the first. Give yourself two weeks where both exist, so that the thing nobody documented gets discovered while someone still knows the answer.

What good looks like on the way in

Everything above is also a specification for your next hire. Before you sign with anyone, agree in writing that every account is created in your name, that you get an export of your data on request without a fee, and that leaving takes a defined and short notice period.

It’s the arrangement we work under. Accounts are yours, data is yours, and the notice period is short on purpose — retention that depends on holding your logins isn’t retention, it’s a hostage situation with an invoice attached.
