A go-to-market strategy is a plan for who you sell to, what you say to them, where you reach them and how you will know it is working. If a document does not answer all four, it is a positioning exercise rather than a plan, and the first week of execution will expose that.
A buyer definition specific enough to build a list from
The test is simple: can somebody who has never met you build a list of five hundred companies from this definition without asking a question? "Mid-market SaaS companies" fails that test. Sector, headcount band, region, the technology they already run and a trigger that makes now the moment passes it.
The trigger is the part most strategies omit and the part that does most of the work. A company that has just opened an office, taken funding, lost a vendor or hired for a role is a different prospect from the same company six months either side of that.
Positioning written as a sentence somebody would repeat
Positioning is not a paragraph about values. It is the sentence a buyer uses when they explain you to a colleague who was not in the room, and if you have not written it they will write it for you, usually less favourably.
It has to name the alternative. Every purchase is a comparison, and a positioning line that does not say what you are instead of leaves the buyer to supply that themselves. Being chosen over doing nothing is a different argument from being chosen over a competitor.
Pricing logic, not a price list
A plan does not need a published price, but it does need the logic: what the price is anchored to, what changes it, and what the floor is. Without that, every deal is negotiated from scratch and the first large prospect sets a precedent nobody agreed to.
Scoped work in particular needs a stated basis. If the answer to "what does this cost" is always "it depends", the thing it depends on should be written down and the same every time.
Channels chosen against the buyer, not against fashion
Channel choice follows from where the buyer already is and how they prefer to be approached, which is often not where the marketing team is most comfortable. Technical buyers who ignore LinkedIn posts will read a detailed email. Procurement teams who ignore email answer a phone call from a name they recognise.
Two channels run properly beat five run thinly. The common failure is not picking the wrong channel, it is picking four and giving none of them enough attention to produce a readable result.
A target list and a measurement plan, both written before launch
The list is the strategy made concrete. Companies, named contacts, tier, and why each tier matters. A plan without a list is a point of view.
Measurement has to be agreed before anything goes live, because afterwards every number becomes an argument. Decide now what counts as a qualified lead, who grades it, and what you will do if the first month underperforms. That last question is the one that separates a plan from a hope.
