Google Ads Account Ownership and Agency Handoff Checklist

Changing PPC agencies is routine. Losing conversion history, breaking billing, or having ads stop mid-campaign during the switch is not — and it is almost always caused by doing the steps in the wrong order.

The rule that prevents most of it: nothing is removed until everything is verified. Below is the sequence we use for Vancouver clients moving accounts between agencies.

Phase 1 — Establish business ownership

Before touching agency access, make sure the account can survive without any agency at all.

• Two internal admins. At least two people at the business hold admin access, on business email addresses that outlast any single employee. One admin is a single point of failure.
• Business-owned account. The Google Ads account itself should have been created by the business. If the agency created it, request admin access for a business address now, while the relationship is still cooperative.
• Agency access via manager link. Agencies work through their Google Ads manager account, linked to yours. That link can be added and removed cleanly; a personal login shared around cannot.

Phase 2 — Map the roles before you change them

Three separate concepts get confused constantly, and confusing them is how ads stop serving:

• Account owner — who created the account and controls admin access.
• Manager account link — the agency's manager account attached to yours, with a defined access level.
• Paying manager — the manager account whose billing setup pays for the account.

Keep this warning front of mind: if the outgoing agency's manager account is set as the paying manager, unlinking it can deactivate the billing setup and stop your ads immediately. Establish a business-owned payment profile and confirm it is active before any manager link is removed.

Phase 3 — Inventory everything before it moves

Document the account as it stands today. This is the record you will test against later.

• Billing: payment profile, billing setup, who is the paying manager, invoice contacts, any credit or promotional balance.
• Conversion tracking: every conversion action, its source (tag, Analytics import, offline import, phone call), its counting and attribution settings, and which ones are set as primary.
• Linked systems: Analytics property, Search Console, Merchant Center, Business Profile, call tracking, CRM and offline conversion imports, and any third-party bid or reporting tools.
• Assets and audiences: remarketing and customer-match lists, asset groups, uploaded creative, and where the source files live.
• Access list: every user and manager link with its access level, exported before changes begin.

Phase 4 — Preserve a baseline

Export the account's recent performance before anything changes: campaign, ad group and conversion-level data for a period long enough to cover a normal cycle, plus the change history. Without a baseline, nobody can tell later whether a dip came from the handoff, a bidding change, or seasonality — and that argument sours more agency transitions than any technical failure.

Store the export somewhere the business controls, not in an agency drive.

Phase 5 — Onboard in parallel, then remove access

Add the incoming agency's manager account while the outgoing one still has access. During the overlap:

1. Confirm the new team can see the full account, including conversion actions and linked accounts.
2. Move billing to the business-owned payment profile and confirm a successful charge.
3. Fire test conversions for every primary conversion action and confirm they record correctly.
4. Re-verify each linked system independently, since links can survive in the interface while no longer passing data.
5. Reconcile a week of reporting against the baseline export.
6. Only then remove the outgoing agency's manager link and user access.

For most Vancouver service businesses this overlap runs two to four weeks — a full conversion cycle plus a billing cycle. The cost of the overlap is trivial next to the cost of rebuilding conversion history.

The one-page checklist

• Two business admins on business email addresses.
• Account owned by the business, agency access via manager link.
• Paying manager identified; billing moved to a business payment profile first.
• Conversions, linked systems, audiences and access levels documented.
• Performance and change history exported to business-controlled storage.
• New agency onboarded in parallel; conversion and billing tests passed.
• Old access removed last.

Google's help documentation on manager accounts, paying managers and billing transfers changes periodically — re-read the current pages on the day you execute the transfer rather than relying on a saved procedure.

If you are mid-transition and want a second pair of eyes, our Vancouver PPC team runs this audit as a standalone engagement, and our reporting service rebuilds the measurement layer once access is settled.
