Verify the handoff before removing routine access
For a planned agency change, confirm business administrator access, save usable exports, name one transition owner and record the dependencies behind live campaigns. Give the incoming team a dated inventory, then test access, billing, inquiry delivery and measurement before retiring the outgoing team’s routine permissions.
A switch cannot guarantee zero disruption. The sequence below is for a cooperative handoff. If an account is compromised or someone is spending without authorization, contain the incident promptly with your administrator and platform support; do not preserve unsafe access merely to finish a checklist.
01 · Ownership and access
Know what the business controls
Confirm a working business-controlled administrator for the domain, website, advertising, analytics, tag manager, commerce, CRM, email and business profiles. Record the account identifier and the level at which access is granted. Test the login and relevant permissions; an invitation or dashboard screenshot alone does not establish control.
Account access, billing responsibility and rights to files are separate questions. List each explicitly. Agree which creative source files, research, reporting exports and licenses transfer under the actual agreement. Agency software, licensed images or fonts, shared audiences and third-party tools may have limits.
Use named users or appropriate manager access, with the permissions each task requires. Keep recovery contacts under business control and use a backup administrator where the platform supports it. Do not put passwords, recovery codes, payment details or customer records in the handoff sheet.
If ownership or exports are disputed, record the exact missing asset and resolve the issue through the contract and platform processes. Set the notice and transition dates from the agreement and the actual dependencies; there is no universal 30-day rule.
02 · The handoff sequence
Seven steps for a planned switch
Inventory the live work
List accounts, account IDs, websites, integrations, domains, feeds, audiences, files, subscriptions and renewal dates. Name the business administrator, outgoing access, incoming owner and billing contact for each. Mark an unverified item as unknown.
Export and check what can be preserved
Save available reports, campaign settings, change history, tracking definitions, tag versions, agreed source files and a website backup. Open the files and confirm their date, scope and usability. An export may not include everything needed to recreate an account or its history.
Keep working campaigns stable
Pause nonessential experiments during the handoff. Record budgets, audiences, exclusions, landing pages and active tests, including the hypothesis, start date, evidence and stop condition. Avoid adding a migration, measurement redesign and campaign rebuild to the same release unless required.
Name the decisions and dependencies
Record unfinished work, known defects, upcoming renewals, who may approve changes and who responds to an incident. Identify anything supplied by the outgoing agency: billing, conversion actions, feeds, automation, call tracking, creative licenses or shared audiences.
Add and test the incoming team
Use individual permissions or a manager relationship. Confirm the incoming person can do the agreed work with the business administrator still in control. Test critical access directly; do not share a master login or assume that accepting an invitation completes the transfer.
Verify continuity before rebuilding
Check the website, landing pages, forms, call delivery, campaign status and billing. Run an authorized, clearly labeled test inquiry and confirm receipt in the intended inbox or CRM; then check the expected measurement event. Keep test records out of qualified-lead reporting. Record the result and responsible person.
Remove outgoing access and recheck
After the agreed routine handoff checks pass, remove the outgoing users, manager links and integrations that are no longer needed. Confirm inherited permissions and recovery contacts too. Retest the live workflow and save the final access list. Replace agency-owned dependencies before disconnecting them.
03 · A common missed dependency
A working login does not prove a complete transfer
In Google Ads, unlinking a manager does not delete the client account’s campaign history. But manager-owned services can change: shared remarketing lists may become unavailable and cross-account conversion tracking can stop recording new clicks after unlinking. Check the Google Ads unlinking guidance against the actual setup.
Monthly invoicing needs a separate check. If the outgoing account is the paying manager, unlinking can stop ads from serving. Arrange and verify the replacement billing setup before unlinking, following Google’s paying-manager documentation.
For other platforms, use the same question: what stops working when this agency’s access or subscription ends? Verify the answer in that platform’s current documentation. Do not assume that Google’s account behavior applies to Meta, a CRM or a storefront.

What is ready, and what still needs work
A fictional service company is switching its advertising and website support. The incoming team can sign in, but the conversion setup still depends on the outgoing manager. This is an illustrative review, not a client result.
| Asset | Verified evidence | Status and next action |
|---|---|---|
| Website and inquiry form | Business admin and incoming editor tested. Backup opened. Labeled test reaches the intended inbox and CRM. | Ready for the planned handoff. Keep the existing form and landing pages; save test evidence privately. |
| Google Ads | Client admin and campaign exports confirmed. Conversion actions still supplied by the outgoing manager. | Hold routine unlinking. The incoming ads owner must confirm the replacement tracking setup and campaign goals, then test it. |
| Creative files | Final exports received. One licensed font is not covered for the incoming team. | Open item. Confirm a transferable license or approved substitute before editing that source file. |
Decision: preserve current campaigns and resolve the tracking dependency before routine unlinking. Log the approved change, test result and access-removal time. A login, an export and a working conversion are three different checks.

04 · Before committing to a switch
Is the problem repairable?
Missed targets alone do not establish that changing agencies will help. The offer, measurement, budget, sales follow-up, approval delays or channel fit may be part of the problem. Compare agreed work, delivered work and qualified outcomes with our agency performance review.
Consider a defined repair
The evidence and access are available, the team can explain the gap and there is an agreed corrective action, owner and review date. Choose a period that fits the work and available evidence.
Prepare a change
The required capability is missing, material mistakes keep repeating, agreed corrections fail or the relationship cannot support the work. Separate the business decision from contract notice, payment and transfer obligations.
For an active security or unauthorized-spend problem, use the incident exception above. A routine transition schedule should not delay containment. For a broader comparison, read when to change agencies.
Questions before the handoff
Who should own accounts and creative files?
The business should retain direct administrative control of its durable accounts. Agree access, billing and file rights separately. Source files, agency tools and third-party licenses depend on the agreement; do not assume every asset transfers automatically.
When should you fire a marketing agency?
Use evidence of the problem, the required capability and whether an agreed correction is credible. Check contract obligations before setting dates. Deal promptly with compromised access or unauthorized activity; deciding how to end the engagement is a separate step.
How do you switch marketing agencies without losing data or momentum?
No handoff can guarantee zero disruption. Confirm business access, preserve usable exports and current settings, assign a transition owner, and test billing, tracking and inquiry delivery before routine access removal. Set the schedule from the actual dependencies; a fixed number of days does not prove readiness.
What should an RFP include for the incoming agency?
State the business problem, current evidence, required work, budget range, constraints, responsibilities, access needs, timing and how proposals will be evaluated. Include the transition inventory and what should remain stable. Use the dedicated agency RFP guide for the full selection process.
