How to Onboard a Marketing Agency in the First 30 Days
Use the first month of an agency relationship to establish a shared understanding of the assignment, secure the necessary access, confirm responsibilities and agree on the first work to be delivered. Treat the timetable as a planning aid. Complex transitions can take longer, and urgent campaigns may require some activity to continue during onboarding.

Both sides have work to do. The client supplies business context and makes decisions. The agency should organize discovery, explain its information needs and turn what it learns into a practical plan.
Carry the sales discussion into delivery.
Ask the agency to hold an internal handoff before your first delivery meeting. Its account lead should arrive with a summary of the problem, promised scope, important constraints and unresolved questions.
Correct that summary together. Review what was agreed in the proposal and contract, including any assumptions that helped the agency estimate the work.
Tim's discussion of client context describes how information gathered during sales can be lost at handoff. The buyer should expect continuity while allowing the delivery team to investigate questions that need more depth.
Confirm the people and their authority.
Identify the agency's delivery lead, the relevant specialists and an escalation contact. On the client side, name the working contact, final approver and people responsible for technical or commercial input.
Explain how decisions are made inside the business. If a founder or legal reviewer has final approval, involve that person at the appropriate stage rather than surprising the agency after production.
Agree on coverage when key people are away. A project should not rely on an approver who cannot be reached before the agreed deadline.
Set up access and protect continuity.
Create an account inventory and confirm administrative control, billing responsibility and necessary permissions. Use the organization's security process to grant access.
CISA's multifactor-authentication guidance provides a useful security baseline. Named access and appropriate permissions also make it easier to remove a departing team member without disrupting everyone else.
If you are replacing an agency, establish who maintains live campaigns during the transition. Confirm that the new team can use the required systems before revoking the outgoing team's ordinary access. Suspected compromise or other serious risks require a security-led response instead.
Establish the starting position.
Ask the agency to document the relevant baseline, data quality and existing commitments. Review the business measures alongside the systems used to report them.
The initial assessment should distinguish confirmed facts from working hypotheses. For example, an apparent fall in leads may reflect a genuine demand change, a form problem or a change in counting. The plan should identify what needs investigation.
Avoid requiring a complete strategic answer before the agency has had access to the evidence. Equally, discovery should produce decisions and priorities within the scope you have bought.
Agree on the first work and the client's contribution.
Ask the agency to propose the initial priorities, explain their order and identify what it needs from you. Include delivery and acceptance criteria.
A first-month plan might include repairing a tracking issue, preparing a campaign brief and reviewing an existing landing page. That is an illustrative sequence, not a standard package every agency should deliver.
Confirm the time needed from your team. A plan that depends on interviews, approvals and internal development will stall if those commitments have not been scheduled.
Review readiness as well as early performance.
At the end of the initial period, review what is operational, what has been learned and which assumptions have changed. Ask whether each party has met its commitments.
Some assignments can produce useful commercial results quickly. Others involve long sales cycles, technical work or brand development. Evaluate early performance in relation to the agreed work and the time needed to observe its effects.
Discuss how the working process feels in specific terms. Repeated information requests, unclear decisions and missed handoffs deserve attention before they become normal.
