MarTech Consulting Pricing Models Compared, After Trying Four of Them

I've billed the same kind of work under all four major pricing models over the years, and each one has a specific way it goes wrong that nobody mentions until you've already lost money to it.

Hourly

Hourly is the easiest to explain and the hardest to profit from on efficient work. The faster and better I got at a task, the less I earned doing it, which is a genuinely bad incentive structure for anyone trying to improve. It's still the right model for genuinely unscoped diagnostic work, where nobody — including me — knows how long the problem will take to find.

Fixed-price

Fixed-price rewards efficiency, which is the appeal, but only works when the scope is genuinely knowable in advance. I underpriced two migration projects badly early on because "migrate this GTM container" sounded like a fixed-size task and turned out to depend entirely on the state of the thing being migrated, which I hadn't audited before quoting.

Fixed-price only works when you've actually looked at what you're fixing. Quoting from a description instead of an inspection is how fixed-price becomes unpaid hourly.

Retainer

Retainers smooth income and build the deepest client knowledge, at the cost of permanent background attention, as I've written about elsewhere. The failure mode specific to pricing is scope drift — a retainer's hours tend to get renegotiated upward informally over time as the client discovers more things to ask for, without the rate ever being revisited to match.

Value-based

Value-based pricing — charging against the dollar impact of the work rather than the hours it takes — is the most lucrative when it works and the hardest to defend when a result is genuinely ambiguous. It also requires a client sophisticated enough to agree on how impact gets measured before the work starts, which fewer clients than you'd expect are actually willing to commit to in writing.

• Hourly: best for genuinely unscoped diagnostic or exploratory work.
• Fixed-price: best after an inspection phase, never from a one-paragraph description.
• Retainer: best for ongoing relationships, needs a scheduled rate and scope review, not an informal one.
• Value-based: best with a sophisticated client and an agreed measurement method locked in before work starts.

The mistake I made for years was picking a pricing model based on habit rather than matching it to the actual shape of the engagement. Now the first thing I ask about any new project is which of these four it actually resembles, before I decide how to price it.
