How do you hire a marketing agency, from shortlist to signed contract?

Most bad agency relationships are decided before anyone signs. Usually it's the order of the hire that fails, not the talent. Here are seven written gates, from the first brief to day-0 access.

Most operators hire an agency the way they would hire a sub they met at a trade show: a couple of calls, a proposal, a gut check, a signature. The sequence is the problem. Scope gets agreed before anyone names the constraint, references come only from the agency's list, and account ownership gets settled after the ads are already running under someone else's login.

This guide is for $1M–$10M service operators who have decided to get outside help and want a repeatable hiring process. If you are replacing a current partner, confirm the signs your current agency isn't working first, then come back here.

This is operator education, not legal advice. Have your attorney review any agreement before you sign, amend, or terminate it.

What does "hiring a marketing agency" actually involve?

It is a procurement sequence with seven gates. Each gate produces a written artifact, and you do not move on until it exists. It is faster than it sounds, because you stop re-explaining your business on calls and start comparing like with like.

Skipping a gate does not save time. It moves the cost to month four, with ad spend already running.

Step 1: What should you write down before you contact any agency?

One page. If you don't write it, an agency will, and their version will fit what they sell.

• The revenue constraint. Pick the one that binds: lead volume, lead quality, close rate, delivery capacity, or speed-to-lead. "We need more leads" is often a follow-up problem in disguise.
• Your qualified-lead definition. Service line, geography, job size, timeline, in your words. If you are unsure what to count, start with the metrics that predict revenue.
• Service lines and geography. What you want to grow, what is at capacity, and where.
• Budget ceiling, split into media and management. Ad spend and agency fees are separate decisions. No number yet? Work through how much to budget for marketing first.
• The 12-month outcome in plain language. "Fill the install calendar in our second market" beats "grow brand awareness."
• One internal owner with decision rights. One person owns the brief, the scores, and the signature. Everyone else advises.

Do you need one agency or several specialists?

Decide this before you build the shortlist, because it changes who belongs on it. The trade-offs are covered in one agency vs multiple vendors.

Step 2: How do you build a shortlist worth evaluating?

Start where the signal is strongest:

• Operator peers in adjacent, non-competing markets. A roofer in another state will tell you who actually moved their numbers.
• Firms whose own marketing shows the discipline they sell. Do they publish how they charge? Does their site answer questions, or only ask for a call?
• Case studies in business models like yours. Calls, estimates, and booked jobs behave differently from ecommerce checkouts.

Then filter out firms without service-business evidence, firms that will not state their commercial model in writing, and firms that will share nothing in writing until you get on a call. Google's own guidance on hiring an SEO adds two more filters: be wary of firms that email you out of the blue, and walk away from anyone who guarantees a #1 ranking (Google Search Central: Do you need an SEO?).

Keep the list short. How many firms to put through a formal RFP is answered in the marketing agency RFP scorecard; the goal here is fewer, better-qualified firms.

Step 3: How do you run the evaluation in writing?

Send every firm the same brief and questions, with a due date, and require written answers. What to judge is covered in how to evaluate a marketing agency. Weights and copy-paste questions are in the marketing agency RFP scorecard.

Three things those posts do not cover:

• When a firm insists on a call first. Treat it as a data point, not a disqualifier. Say you are glad to talk after you have written answers. A firm that will not write anything down is showing you how its reporting will feel.
• Score before you talk. After a friendly call you will read that firm's answers more generously. Score first, then use any conversation to test the scores.
• "Who actually does the work" gets answered in writing. Names or roles, what the founder touches, what is subcontracted.

Keep every brief, answer, and score in one folder. It becomes the record you reconcile at Step 6.

Commercial model is a gate, not a footnote. Before you compare proposals, see how fixed-fee engagements are structured and compare models in retainer vs fixed-fee marketing.

Step 4: What should you ask references, and which references count?

Every agency has three happy clients. Ask for references in your business model, then find at least one yourself, ideally a former client the agency did not hand-pick. Google's hiring guidance says the same: check business references and ask past clients whether the service was useful, easy to work with, and produced results (Google Search Central).

Ask about operating rhythm, not bragging numbers:

• Did the standard report tie to revenue and qualified leads, or did you have to ask every month?
• When numbers dipped, who owned the diagnosis?
• Who did the day-to-day work, compared with who sold it?
• What did the exit or handoff look like?
• Would you buy the same scope again at the same price?

Step 5: Should you buy a paid first deliverable before a long commitment?

Usually, yes. A scoped, paid, keepable first deliverable (an audit, a roadmap, a diagnostic) de-risks both sides. You see how the firm thinks, whether it ships when promised, and whether its diagnosis matches yours. The firm sees your real data before committing to a scope.

Be careful with free audits; most are sales decks built to reach a predetermined recommendation. And limit access while anyone is only diagnosing. Google advises that if an SEO offers an audit, you grant read access to Search Console at that stage, not write access (Google Search Central). Read access to diagnose; working access at signature, on accounts you own.

How Prime handles this step

Every Prime engagement begins with the Growth Blueprint: a $5,000 one-time fee, delivered in 4 weeks as a detailed PDF audit, a 12-month roadmap, and a 15-minute Loom walkthrough. It is a finished deliverable, not a trial. You keep it whether or not you continue, and it is not refundable because the work is already done. Details are on Growth Blueprint pricing.

Step 6: How do you check a proposal against your brief?

Put the proposal and your brief side by side and mark it up:

• Is your constraint restated, and does the plan address it first?
• Is scope explicit about what is in and out?
• Are media and management separated? Is ad spend paid directly to the platform, or passed through with a markup?
• Is reporting defined? Which metrics, what cadence, tied to your lead definition.
• Who owns the accounts the work will run in?
• What changes the price, and how is a change approved?

Anything missing goes back in writing before the contract stage. If the gaps are about the commercial model itself, retainer vs fixed-fee marketing covers how each model shapes incentives.

Step 7: What has to be true before you sign?

This is a signature checklist, not a clause review. For the clause-by-clause list, read the contract red flags to review with your attorney.

• Accounts exist, or will be created, under your business, with you as admin. Google Ads, GA4, Search Console, Business Profile, Tag Manager, CRM, call tracking. In Google Ads, when a manager account creates a new client account, that manager automatically becomes the owner; the client account keeps its data and can unlink an owner, but you need admin access on your side to do it (Google Ads Help: ownership of client accounts). Google's Tag Manager docs recommend at least two administrators and accounts managed by someone in your organization, not an outside agency (Tag Manager Help: managing users and permissions). Make sure your agency agrees to this in writing before any account is created.
• Scope, reporting cadence, and your qualified-lead definition are attached to the agreement.
• Minimum term, notice window, and renewal mechanics are understood and calendared. Runway to install a system is reasonable. Asymmetry is the flag: a long lock for you, easy outs for them, exit fees. For comparison, Prime publishes its own terms: the Growth Engine is $5,000+/month with a 6-month minimum, then month-to-month with 30 days' written notice on either side, and no auto-renewal trap or exit fee (pricing).
• Exit mechanics are on paper. Confirm in writing what comes back to you if the relationship ends: admin confirmations, data exports, creative source files, and documentation of what is running.
• Your attorney has reviewed the agreement.

What happens the week after you sign?

Day zero is an access handoff: role-based access on accounts you own, and a baseline before anything changes. Then read what the first 30 days should look like.

How does a written hiring process fit an async firm like Prime?

Prime's buying process is the written version of this post. The application takes about five minutes and is reviewed personally, with a response within 48 hours. No sales calls, demos, or live presentations. Approved applicants receive a Blueprint checkout link plus an intake form that replaces the kickoff call.

To see what an installed system looks like, browse the service-business case studies. Read them as patterns, not as a promise about your market.

Decide with a clear next step

Run the seven gates with any firm you are considering, including us. Write the brief, keep the shortlist short, get everything in writing, and do not sign until access, scope, and exit are on paper and your attorney has read the agreement.

If you want Prime on your shortlist, the application is the written first step: apply. Enrollment is selective (four new clients per month). If you are earlier in the decision, take the Revenue System Scorecard first to name the constraint your brief should lead with.
