Hiring a B2B marketing firm: engagement models, real cost, and contract terms

Engagement models compared

Five structures cover almost every way software companies buy marketing. The pitch varies more than the structure, so compare structures first and vendors second.

Read the last column carefully. Every model works when its conditions hold, and each fails in a specific, predictable way when they do not.

What a firm actually costs against building it internally

Compare total cost of ownership, not retainer against salary. An internal build that covers the same surface as a mid-tier retainer usually needs a senior generalist, a content producer or contractor budget, a paid media specialist or contractor, plus tooling for analytics, SEO and AI search visibility, and creative. Add employer taxes, benefits, and equipment on top of every salary, then add the months you are paying before anything ships.

Use your own numbers rather than ours. Take the loaded cost of the two roles you would hire, add your realistic contractor spend for the specialisms those two cannot cover, add annual tooling divided by twelve, then divide by the number of channels you need running. That per-channel number is the honest comparison against a retainer line.

The two costs people leave out of the internal case are hiring time and single-point risk. Three to six months of a vacant funnel is a real number, and a one-person marketing team means the program stops when that person takes a vacation or leaves.

• In-house wins when channel needs are narrow and you can hire and manage senior talent
• A firm wins when you need several specialisms at once and cannot justify several hires
• A firm also wins when work front-loads then drops to maintenance, which is the shape of a rebuild plus organic
• The durable hybrid is one internal owner holding strategy with an outside firm running execution

How to structure the contract

Most disputes are scope disputes wearing a performance costume. The way to avoid them is to make the boring parts explicit before signature, while you still have leverage and goodwill.

Ask for each item below in the agreement itself, not the proposal deck. If a firm resists putting the out-of-scope list in writing, you have learned the thing you needed to learn.

• Term: six months minimum for anything involving search, content, or a rebuild, because the work front-loads and the return back-loads
• Scope: a dated deliverable list for the first 90 days, plus a written list of what is out of scope
• Named team: the strategist and executors by name and role, not a capability roster
• Measurement: the single metric the engagement is judged on, plus the leading indicators reviewed at day 90
• Pass-through costs: media spend, licenses, and third-party fees itemized outside the retainer
• IP and exit: you own the site, content, accounts, and data, with a documented 30-day handover
• Change control: how added scope gets priced, so it does not become a monthly negotiation

Why we run a 6-month minimum

Our own term is six months on every tier, and that is a constraint on you, so it deserves a reason. The first 30 to 60 days of an integrated program is build: site architecture, technical fixes, entity and schema work, content system, tracking, and paid structure. Those produce almost nothing on their own. The return arrives when the build starts compounding, which for organic and AI search visibility is typically months three through nine.

A three-month term means you pay for the build and leave before it earns. We would rather turn down an engagement than sell that shape, and we say so on the first call when the timeline does not fit.

Where a firm like ours is the right call, and where it is not

We are a search-and-AI-search-led integrated firm for B2B and B2C software companies: website, SEO, AEO, GEO, content, and paid under one strategist, one plan, one measurement layer. That is the correct purchase when your constraint is fragmentation across vendors, or a site that cannot support the content you want to publish, and when you do not have a senior marketing leader you are ready to hire.

It is the wrong purchase in three cases we regularly turn down. If you can hire and manage a strong senior generalist and your needs are narrow, build in-house. If you need positioning, naming, or category work as the main deliverable, a product marketing consultancy will do it better. If you need outbound conversations this quarter, an ABM or outbound firm is the right structure, and we refer software companies to Managed Outbound.

We are obviously biased toward the retainer model, since that is what we sell. The cost math above is written so you can run it with your own numbers and reach a different conclusion.

A four-week process that does not burn a quarter

Week one, write the constraint in one sentence and pick the engagement model that fixes it. Week two, shortlist three firms inside that model only, so the proposals are comparable. Week three, run the diligence conversations and ask for the dated 90-day list and the out-of-scope list. Week four, decide on the out-of-scope list rather than the capability list.

If you cannot score a candidate on the same dimensions as the others, that is the answer about that candidate.

Pricing, in public

Every engagement is published pricing on a 6-month minimum: Ignite at $7.5K/mo plus a one-time $4,500 implementation fee, Momentum at $15K/mo, Dominate at $30K/mo, and Custom starting at $50K/mo for a fractional multidisciplinary pod. You will know what this costs before you ever get on a call.
