A marketing engagement should leave your business with more capability, more understanding and a clearer path forward.
Ask what will remain available to your team when the campaign ends. That conversation belongs at the beginning, while everyone is deciding how the work will run—not during an awkward offboarding call six months later.
1. Which accounts can our team access?
List the advertising accounts, analytics tools, landing pages, email systems, CRM workflows, creative files and other infrastructure involved. Identify who administers each one and what your team can actually see.
A screenshot of a dashboard is different from access to the account behind it. A report is different from owning the history that produced the report.
2. What can we export?
Ask for an example export before you need one. Can you retrieve campaign history, source labels, creative versions, audience or lead records that belong to your company, and the other records relevant to the engagement? What format will they arrive in? Who is responsible for the handoff?
3. What does each reported result mean?
Agree on the definitions of a lead, qualified inquiry, conversion and sale. Ask how duplicates, refunds, repeat customers and assisted conversions are handled when they matter to the campaign.
A precise definition makes the report useful to the people making the next decision. It also prevents the largest available number from quietly becoming the success metric.
That distinction is central to what to measure beyond reach and impressions.
4. What can the report actually establish?
Ask the partner to separate observed actions from assumptions. Where does tracking stop? Which results depend on another company’s records? What attribution model is being used? Which outcomes are plausible contributions rather than cleanly attributable conversions?
A clear limitation is more useful than a confident number nobody can explain.
5. What knowledge is being transferred?
A good partner should not need to teach your team every specialized skill they possess. But the business should understand what was learned: which audiences responded, which messages failed, what the funnel revealed, which operating assumptions changed and what should happen next.
If all of the useful learning remains trapped inside the vendor, the company may be renting more than execution.
6. What happens when we change direction?
Document the handover process: files, account access, reporting history, unfinished work, documentation, dependencies and named owners. Discuss what the team will need to continue operating if the engagement changes or ends.
This is the practical side of building owned continuity instead of unnecessary dependency. You are evaluating the infrastructure behind the campaign alongside the creative and distribution.
7. Who owns the next decision?
Reporting without a decision loop creates recurring theater. Decide who reviews the evidence, what thresholds matter and who has authority to continue, increase, change or stop the work.
The partner can recommend. The business still needs somebody accountable for the choice. That is the same operating problem behind Strategy vs. Execution.
The healthiest vendor relationship creates value now without creating avoidable dependence later.
A simple pre-hire test
Imagine the relationship ends twelve months from now on perfectly good terms. Can your team still access its accounts, understand the performance history, find the files, explain what was learned and decide what to do next?
If the answer is unclear before the engagement begins, make it clear before signing.
