#Why the published ranges are useless
Search for what a marketing consultant charges per hour and you will find ranges spanning an order of magnitude. That is not because anybody is being evasive. It is because the term covers a solo practitioner working from home and a senior partner at a firm with a research department, and both accurately describe themselves as marketing consultants.
The same applies to agency retainers. A monthly fee means nothing without knowing how many people are on the account, how senior they are, how much of their time you have, and what is included versus billed separately.
So the useful move is to stop asking what it costs and start asking how it is structured and who does the work. Those two answers tell you more about what you will receive than any number.
#The five structures and what each pushes toward
Hourly billing is transparent and it rewards hours. It suits defined, bounded work and it suits a buyer who wants to control scope tightly. It is a poor fit for anything ongoing, because the incentive to be efficient works against the provider.
Monthly retainers buy availability and continuity. They are the most common arrangement and the least specific, which is why the question that matters is what the retainer actually includes — hours, deliverables, people, or simply access.
Percentage of media spend is the automotive default for paid media and it rewards spending more. Project pricing rewards finishing, which is good, and rewards scoping conservatively, which cuts both ways. Performance or commission pricing rewards whatever the metric is, which is excellent when the metric is a booked appointment and dangerous when it is a lead the vendor defines.
TABLE
Marketing pricing structures and the behaviour each one produces
No structure is wrong. Each one applies a predictable pressure, and a buyer should know which one they have bought before they are surprised by it.
| Structure | Suits | Pushes toward | The question to ask |
|---|---|---|---|
| Hourly | Defined, bounded pieces of work | More hours; poor fit for ongoing work | What is your estimate, and what happens when it is exceeded? |
| Monthly retainer | Continuity and availability | Stability; vagueness about what is included | What exactly does the retainer include — hours, deliverables, or access? |
| Percentage of media spend | Paid media management at scale | Higher spend; reluctance to cut a plateauing channel | Does the percentage apply to third-party listing invoices too? |
| Project / fixed fee | A defined outcome with a clear end | Finishing, and conservative scoping | What is explicitly out of scope, in writing? |
| Performance / per lead | Outcomes both sides can measure identically | Volume of whatever counts, as defined by the vendor | Who defines the outcome, and can two vendors count the same one? |
| Fractional leadership | A store with spend but nobody senior owning it | Advice, including advice to spend less | Do you sell any of the channels you would be reviewing? |

#The three questions that reveal the most
What would you tell us to stop doing? An agency that has never recommended reducing anything is either running a flawless account or is not looking. The answer also tells you whether their structure allows them to say it — a percentage-of-spend agency recommending a spend reduction is recommending its own pay cut, which is worth noticing when they do it.
What happens if we halve the budget? This distinguishes a provider whose value is proportional to spend from one whose value is the thinking. Both exist and both are legitimate; you should know which you are hiring.
Who exactly does the work? The gap between the people in the pitch and the people on the account is the oldest problem in agency buying, and it is entirely answerable in advance by asking for names and time allocations rather than for an org chart.
#Why the conflict is structural rather than moral
Any provider who both recommends and executes is being asked to evaluate their own work. That is not a character problem and it does not resolve by hiring nicer people; it is the shape of the arrangement.
It has two practical consequences. A vendor's diagnosis will tend to name a constraint their service addresses, and a vendor's report will tend to use the metrics their service moves. Neither requires bad faith. Both are inevitable.
The available responses are to separate advice from execution, or to accept the conflict and compensate for it with independent measurement. The first is what the marketing consulting and virtual marketing manager models exist to provide; the second requires a definition of a lead that every vendor uses, which most stores do not have.
#What to do before asking anyone for a price
Write down the constraint. A store that cannot say whether its problem is visibility, conversion or follow-up will receive proposals aimed at whatever each provider sells, and will have no basis for comparing them.
Write down what a lead is, in one sentence, and require every proposal to use it. This single requirement makes otherwise incomparable proposals comparable, and it exposes providers whose economics depend on a looser definition.
Then ask for the fee structure in writing, with what is out of scope stated explicitly. Nearly every dispute between a store and an agency is a scope dispute wearing a performance argument as a costume, and it is settled cheaply at the start.
