A common pattern in agency pitches: a business comes in wanting help running media buys — placing and optimizing paid ads — and leaves the pitch meeting with a proposal that includes a full brand refresh, a new website, and a "positioning workshop" before any ads even launch. Agencies aren't necessarily acting in bad faith when this happens; many genuinely believe brand foundations need fixing before performance work can succeed. But it's worth knowing upfront whether you're hiring for execution on a defined problem or opening the door to a much larger, more expensive engagement.
| Model | How it works | Watch for |
|---|---|---|
| Retainer | Flat monthly fee for a defined scope of work | Scope creep — what's included can quietly narrow over time without a renegotiation |
| Commission (% of ad spend) | Agency earns a percentage, typically 10–20%, of managed media budget | Incentive to recommend spending more, not necessarily spending better |
| Project fee | Fixed price for a defined deliverable (a campaign launch, a rebrand) | Change requests outside original scope often bill separately and add up fast |
| Performance-based | Fee tied to results (cost per lead, revenue share) | Rare and usually reserved for agencies with strong data access and trust built over time |
A request for proposal doesn't need to be a 20-page document — a focused RFP that specifies your actual budget range, the specific problem you're trying to solve, and two or three required deliverables gets more useful, comparable responses than a vague "tell us what you'd do for our brand" ask. Sending the same specific brief to three or four agencies lets you compare apples to apples; an open-ended ask invites wildly different scopes and prices that are hard to evaluate against each other.
An Agency of Record (AOR) relationship gives one agency ongoing, exclusive responsibility for a defined scope — typically all paid media, or all creative, or the full marketing function — usually under a longer-term retainer. Project-based engagements are scoped to a single deliverable: a campaign launch, a rebrand, a one-time video production. AOR relationships make sense once a business has enough steady marketing volume to justify an agency building deep institutional knowledge of the brand, since that knowledge compounds — the agency stops re-explaining the basics every engagement and starts making faster, better-informed decisions. Project-based engagements make more sense for one-off needs or for testing an agency's quality before committing to a longer AOR relationship, which is a common and reasonable way to de-risk a bigger commitment.
Most agency contracts specify a defined number of revision rounds per deliverable, commonly two or three, with additional rounds billed separately. This isn't usually a sign of a stingy agency — unlimited revisions as a standard offering tends to produce worse outcomes for both sides, since it removes the pressure to give clear, complete feedback early and can drag a simple deliverable through weeks of incremental tweaks. Clarifying the revision structure upfront, and giving thorough feedback in the first round rather than trickling in changes over many rounds, is one of the more effective ways clients can speed up agency turnaround without paying for extra rounds.
Many agency proposals bundle in an expensive website rebuild you may not need. UIXDraft's 180+ templates cover landing pages and full marketing sites you can launch yourself, keeping the agency relationship focused on media and strategy.

Similarly, pressure to sign quickly with a "limited spots this quarter" framing is a sales tactic more than a reflection of real capacity constraints, and it's worth being just as skeptical of it in an agency pitch as you would be anywhere else it shows up.
Who owns the creative brief — the document defining objectives, audience, and key messages before creative work begins — is also worth clarifying early. Agencies that skip a written brief and move straight to concepts often produce work that looks polished but misses the actual strategic target, since there was no agreed-upon reference point to hold the work against. A strong agency insists on a collaborative brief process before any creative starts, even if it adds a few days to the front end of the engagement.
Internal alignment before the search even starts prevents a common failure mode: different stakeholders on the client side quietly holding different goals for the engagement, which surfaces mid-project as conflicting feedback the agency can't reconcile. A short internal document agreeing on the primary objective and who has final sign-off authority, written before the first agency conversation, saves significant friction later.
It creates a structural incentive to recommend more spend rather than necessarily better-optimized spend, which is worth being aware of, though it doesn't automatically mean the agency is acting against your interests. Asking directly how they'd advise you if the right answer were to spend less is a reasonable way to test this in a pitch conversation.
For paid media specifically, 60–90 days is usually enough to judge whether an agency's approach is working, since most channels need at least a few weeks to exit early testing and stabilize. Anything requiring a full year commitment before any performance checkpoint is worth negotiating down.
Full-service is simpler to manage but usually costs more and can be less current on any single channel than a specialist. Multiple specialists often perform better per channel but require someone internally to coordinate strategy across them — worth the tradeoff mainly once you have the internal bandwidth to manage multiple vendor relationships.
