You’ve decided to leave. The old relationship is ending, a replacement has been chosen, and your first impulse may be to remove the former agency from every account you can find.

Pause before you do that. When you’re switching marketing agencies, the first job is to confirm who can keep your accounts and inquiry paths working after the change. Access removal comes later.

This is not another test for deciding whether the agency should be fired. If that decision is still open, read when to fire your marketing agency. It is also not a guide to comparing replacements. The home service marketing agency selection guide covers that decision.

This is the handoff itself. The basic idea is simple: do not remove the old route until your business has a confirmed way in and the next person can take responsibility. Check the calls, forms, pages, and accounts that matter before the cutoff, then check them again afterward.

Access Removal Comes Late in a Marketing Agency Transition

An outgoing agency may still be the person or team currently authorized to act inside an account. It may be able to confirm where a campaign sends traffic, identify the active landing page, or answer a question about a setting. Its role will vary by system and by business, but the dependency matters until someone else has been verified and assigned.

If you remove that access first, you can create an awkward gap. The old team can no longer act, the new team may not yet have the permission or context it needs, and you are left deciding who is responsible while the marketing is still live.

The order should be deliberate. First, identify the accounts and inquiry paths your business actually uses. Confirm a business-controlled access or recovery route and make sure the next responsible person can act. Check what is working now. Only then should you remove the outgoing agency under the current platform process and applicable agreement. Afterward, check the same paths again.

That order does not promise an interruption-free transition. It gives you a way to find obvious dependencies while the people who understand the current setup can still respond.

Inventory the Marketing System You Actually Use

A generic agency handoff checklist can create false confidence because it assumes every company has the same setup. Start with the route a real inquiry takes through your business, then look at the few accounts and responsibilities that keep that route working.

Start with calls. Identify the public number a customer uses and the business destination that should receive the call. If your advertising uses a tracking number, make sure you understand where it sends the call and who can confirm that route.

Do the same for forms. Know where the form appears, where the submission should arrive, and who is expected to see it. If a form feeds a separate inbox or system, do not assume it will transfer with the website or ad account.

A landing page used by an ad campaign may sit outside your main website. Confirm which live page the campaign uses and who can currently administer it. Control of the main website does not automatically answer the landing-page question.

For ad accounts, confirm who can sign in directly, what level of access the relevant users have, and which manager relationships exist. The replacement team should also be able to see the analytics or tracking context it needs. Access to an ad account does not automatically provide access to every connected reporting or tracking property.

If an advertising platform bills your business directly, confirm who can see the billing information needed for the handoff and who will respond if a question appears. This is a responsibility check, not an instruction to alter payment details during the transition.

Google Ads Account Access Is Not the Same as Business Ownership

This distinction is easy to blur because Google Ads uses several terms that sound broader than they are.

Your business records and agreements are what you use to address business ownership of an account or asset. Google Ads shows permissions and relationships inside its platform. Those platform records can tell you who can act in Google Ads. They do not settle every wider ownership question.

According to Google’s current explanation of Google Ads account access levels, every user receives an access level that controls which features that user can affect. An Admin user can give account access, change another user’s access level, cancel invitations, accept or reject manager link requests, and unlink manager accounts.

Admin access is still a permission level. It does not make the user the legal or business owner of every account, campaign, file, phone number, or data set connected to the marketing.

A manager link is another platform relationship. Google also uses an “ownership” label for a manager-account setting. When that setting applies, admins of the manager account receive added abilities in the client account, including the ability to edit user access, managers, and product links. That label describes what a linked manager can do inside Google Ads. It should not be used to decide who owns an asset outside Google’s permission model.

For the handoff, keep those distinctions clear. Confirm that your business has a working direct sign-in or recovery route, that the right user can administer the account, that you understand which manager relationships are linked, and that someone is responsible after the change. This prevents a platform label from answering a question it was not built to answer.

Record the Current State Before Anyone Changes Access

Once you know who can act, capture a baseline. The point is not to document every screen in the marketing stack. It is to give the next responsible person enough context to recognize what was live before the cutoff and to see what changed afterward.

Make a short written note of the current landing destinations, active campaign status, material settings the replacement team needs to recognize, tracking references, and billing responsibility. Name the person responsible for anything that still needs attention. “New agency” is not specific enough if no one knows who is expected to respond.

Inside Google Ads, change history can add useful context. Google says it lists account, campaign, and ad-group changes from the past two years. You can filter it by date range, change type, campaign, or ad group, and it can show who made certain changes when each person uses an individual login.

Treat it as one source, not the entire handoff record. Google notes that some account-level setting changes and changes made by a Google representative during a consultation may not appear. It also says nothing about a form destination, a call path, a page outside the ad account, or another system your business uses.

Check Operating Continuity Before the Cutoff

Now you can check the paths that matter to your business. This is a bounded observation, not a live reconfiguration project and not proof that every dependency has been found.

Confirm that an intended landing page loads. Use the normal business process to make sure calls and forms reach the expected destination. Make sure the replacement team can view the ad account and the reporting or tracking context it needs, and that the person responsible for billing can see the information needed for the handoff.

Do not turn this check into a round of campaign, call-routing, billing, tracking, or website changes. Do not click your own ads to test them. If an item does not match the baseline, record the mismatch and assign it to the person responsible for that system.

The limits matter. One successful form submission does not prove that every form works. One call does not prove every tracking route is correct. A visible account does not prove the new team can administer it. Note what you actually checked without stretching that result into a promise.

Keep the old agency’s access in place until the business-controlled access or recovery route is confirmed, the next person can carry the responsibility, and this bounded check has passed for the items your business depends on.

Remove the Old Agency After the Replacement Path Is Confirmed

The cutoff point arrives after your business has a confirmed access or recovery route, the next responsible person can act, and the important paths have produced the expected result in your check.

Then use the current procedure for each platform and follow the applicable agreement. The procedure and available relationship types will differ across the systems you use, so a Google Ads instruction should not be treated as a universal removal method.

Google Ads is a good example of why precise language matters. A user with Admin access, another user with a lower access level, a linked manager account, and a manager account with Google’s ownership setting are not interchangeable concepts. Removing a user is not the same action as unlinking a manager account. Neither action, by itself, resolves wider questions about who owns business assets.

You do not need to rush past those distinctions just because the relationship has ended. Move decisively, but make the removal the final dependency step instead of the opening move.

Recheck Calls, Forms, Accounts, and Responsibility

After the access changes are complete, repeat the bounded check against your baseline. Look at the same call and form paths, intended pages, ad-account access, analytics or tracking context, and billing responsibility that you recorded before the cutoff.

For Google Ads, change history may help you compare the account state and identify certain recorded changes. Keep its limitations in view. It is not a record of the rest of your marketing system, and Google does not claim that every account-level or representative change will appear.

If something no longer matches, give the issue to a named person with a clear question: which page differs, which destination did not receive the inquiry, which permission is missing, or which responsibility remains unassigned. That person can then work with the appropriate platform, provider, or party under the applicable agreement.

A careful handoff reduces avoidable gaps. It cannot guarantee zero downtime, prove that every dependency was discovered, or guarantee that every asset will transfer. The marketing agency transition is complete only when the new responsibilities are clear and the critical paths in your record have been checked after the change.

Keep the Sequence Disciplined

You can end an agency relationship firmly without treating the access screen as the whole transition. Understand what must keep working, confirm the business-controlled replacement route, and make sure someone is ready to take responsibility. Check that route before you remove the old one, then check it again.

That sequence respects two separate questions. Your records and agreements address business ownership. Platform permissions show who can currently act inside a specific system. Keeping those questions separate gives the new team a clearer starting point and gives you a more useful record if something does not match after the cutoff.
