Find hidden assumptions in a marketing proposal
Review a marketing proposal for hidden media, production, revision, ownership and reporting assumptions before comparing fees or approving work.
What must be explicit before approval?
List what the provider will do, what the client must supply and what evidence will establish completion. Hidden assumptions often sit between those categories. A campaign setup can depend on missing creative, account access or an approved offer. If nobody owns the dependency, the proposal can be accepted while the work remains unable to start.
A performance promise also needs a measurement boundary. Google Ads explains ROAS in terms of reported conversion value relative to ad cost; that is not company profit. A proposal should not move between ROAS, revenue and contribution as if they were interchangeable outcomes. [About Target ROAS bidding]
An annotated proposal review checklist
| Area | Question | Evidence to request |
|---|---|---|
| Ad spend | Is media paid separately from service work? | Explicit budget boundary and payer |
| Production | Who writes, designs and supplies source assets? | Deliverable list and input owner |
| Revisions | What triggers another review or a scope change? | Defined revision process |
| Ownership | Who can access and retain accounts, files and assets? | Approved access and handoff terms |
| Reporting | Which outcomes, sources and definitions are used? | Sample report with measurement boundaries |
| Acceptance | What public or durable evidence proves completion? | Task-specific acceptance criteria |
| Dependencies | What blocks launch and who resolves it? | Input checklist with responsible roles |
The checklist is operational guidance, not legal advice or a substitute for reviewing the actual agreement. Do not assume a provider’s standard terms answer these questions in the way your team expects. Record the answer and its source so later handoffs do not rely on a sales-call memory.
A small ambiguity that changes the comparison
Illustrative example: Proposal A says “campaign management and reporting.” Proposal B says “campaign setup, ongoing management, two approved creative variants and a monthly source-level report.” Neither is automatically better. Ask what A includes and whether B’s variants cover the formats and review process you actually need.
If A excludes production, compare its fee plus the required production scope rather than its fee alone. If B includes work you do not need, identify whether the scope can change. Keep vendor prices fictional in teaching examples or verify current quoted amounts before publishing a real comparison.
Which results can the provider actually establish?
Separate configuration, event delivery and business outcomes. A tag being installed does not establish a delivered event. A delivered inquiry event does not establish a qualified opportunity. A report should state the source, dates, attribution rule and unresolved coverage rather than filling every unknown with zero.
- Define the conversion action and duplicate-counting rule.
- Identify which CRM or product state supplies qualification.
- Keep technical tests separate from real visitor behavior.
- State which costs and revenue types the return calculation includes.
- Avoid universal performance guarantees without substantiation.
Finish with a resolved scope record
Mark each checklist item accepted, clarified, excluded or unresolved. Link consequential changes back to the final proposal version. If an essential input is missing, record the dependency and what independent work may proceed. Approval should apply to a concrete scope rather than an evolving conversation.
I would compare proposals only after this pass. The result is a more honest choice between actual obligations, costs and delivery evidence. A cheaper headline can still represent a larger unfinished job, while a broader package may include work that does not support the intended decision.
