How to write a marketing plan that survives contact with the team

We start with the question that comes up in most first meetings: we have a budget, we have a team, but we don't know where to begin. This is exactly the moment when most marketing plans are created that later sit in a drawer. The reason is different: the document describes the world, not the team's work.

Below you'll find a practical answer to the question of how to write a marketing plan that can actually be implemented in a B2B company. No academic definitions, but concrete steps and questions you need to ask yourself before the first paragraph.

How to write a marketing plan: where to start when you have no data

The first instinct is usually this: we sit down and write goals. That's a mistake. A marketing plan starts with an audit, because without it goals are just guessing. In the classic approach to marketing planning (e.g. Kotler, Keller, Marketing Management) the situational audit is the starting point of the active part of planning¹. Marketing goals only make sense when they are based on real customer behavior in the markets where we actually operate.

The audit doesn't have to be a hundred-page report. It's enough to answer five questions:

• Where did the customers who bought from us in the last twelve months come from? Channel, person, reason.
• How many customers did we lose and why? This is often more important than acquisition.
• What is the competition doing that our customers actually compare us to? Not the whole industry, just two or three names.
• What data do we have about the market we serve? If we don't have it, we need to collect it before the plan is written.
• What has changed in the last year in the way customers make decisions?

This last question is underrated. In B2B, the purchasing decision rarely belongs to one person. If in your company sales only talks to the purchasing department, but the decision is made by the technical director, the marketing plan must take this into account. Otherwise you'll generate leads that never reach the stage of a conversation about implementation.

If the audit shows that you don't know where customers come from, that's not a problem with the plan. It's a data problem that needs to be solved before planning. It's worth reaching for an external perspective at that point, for example as part of a B2B marketing strategy, because the internal team often can't see its own assumptions.

A marketing plan structure that fits on a few pages

A marketing plan structure does not have to be elaborate. In practice, a document with six sections that fits on eight to twelve pages works well. Longer plans are rarely read in full, and people outside the marketing department return to them even less often.

A proven layout looks like this:

1. Starting situation. Three paragraphs: what we know about the market, what we know about ourselves, what we know about the competition. With numbers, not opinions.
2. Marketing objectives. A separate section, because this is the most commonly confused element. Marketing objectives concern matching products to markets, that is, what we sell, where, and to whom. Objectives around price, distribution, or advertising sit at a lower level and should not be confused with marketing objectives, even though they are part of the strategy needed to achieve them.
3. Target groups. Not personas with a name and a photo, but a description of the buying situation: who decides, who blocks, who pays.
4. Activities. Channels, topics, formats. With an owner and a deadline assigned.
5. Budget. Divided by activities, not by accounting categories.
6. Measurement. What we check, when, and what we will treat as a signal that something is not working.

This order matters. If you start with activities, the plan will be a wish list. If you start with objectives without an audit, the objectives will be wishful. The measurement section at the end is not accidental: only once you know what you are doing can you sensibly say how you will check it.

Why objectives must be measurable, but do not have to be ambitious

Textbooks repeat that goals should be measurable. That is true, but in B2B something else fails more often: the goals are measurable, yet nobody believes they will actually happen. The team sees the number, nods, and goes back to daily work. If that is what happens, the goal is poorly set, even if it meets every SMART criterion.

It is better to set a goal that is slightly uncomfortable but understandable than one that requires faith. A goal is understandable when the team can point to the action on Monday that moves it one step forward. Forty percent of leads fail this test, because they do not say where they come from. Example: instead of "increase the number of leads by 40 percent", better to say "win twelve clients from the machine manufacturers segment, half of whom will move to the quote stage". The second version tells the team what to do on Monday.

A marketing plan step by step: from goal to accountability

A marketing plan step by step looks different from its structure. The structure is a table of contents, the steps are the order in which you work on the document. It is worth keeping them separate, otherwise planning turns into writing chapters.

The order that works in B2B companies:

1. Gather data. Sales, marketing, customer service. An hour of conversation with each of these teams gives you more than a week of analysis on your own.
2. Name the problem. One sentence that everyone understands. If you cannot formulate it, you do not have a plan yet.
3. Set one main goal and two or three supporting goals. More goals mean none of them is a priority.
4. Choose channels. Not the ones that are trendy, only the ones where your clients actually make decisions.
5. Break activities down by quarter. With an owner and a deadline.
6. Assign a budget. To activities, not to categories.
7. Set a review rhythm. Who checks what, and when.

Point seven is the one that most often decides whether the plan survives. A plan without a review rhythm is a document that will age within a month. In practice, a monthly thirty-minute meeting and one longer quarterly meeting, where you can change direction, are enough.

Who is responsible for the marketing plan in B2B? In companies of up to twenty people, the plan is usually written by the owner or the person responsible for sales. In larger organizations, the plan is created in marketing, but it is approved by the board together with the head of sales. If sales does not take part in creating the plan, it will treat it as a document imposed from above. This is the most common cause of misalignment between departments.

In the interim marketing model, where a manager comes in for a set period and is accountable for the result, the plan is the first document that gets created. Without it, there is nothing to be accountable for. We write more about this approach in the context of marketing strategy for B2B companies.

How to measure a plan without measuring everything

The biggest enemy of measurement in B2B marketing is too many metrics. Teams measure everything because everything can be measured, and then nobody knows which metric matters. In practice, three levels of measurement are enough.

Activity level is necessary, but it cannot be the goal. If the team reports only the number of publications, it will produce content that nobody reads. Progress level matters most, because it shows whether the activities translate into client conversations. Result level is the final test, but it appears too rarely to steer day-to-day work.

It is also worth remembering that measurement is not always simple. In marketing analytics, the effect of one action often depends on another. For example, the impact of advertising on sales changes with price. This means a channel cannot be evaluated in isolation. In practice, you have to look at combinations, not single indicators.

The most common mistakes in B2B marketing plans

At one manufacturing company, the 2023 plan assumed 30 percent growth in LinkedIn leads. After a quarter, it turned out that the purchasing department did not use that channel at all, and purchasing decisions were made in conversations at industry trade shows. The plan was measurable, but it described a different world than the one the team worked in.

• A plan without an owner. The document gets created, but nobody is responsible for executing it. In practice, this means that after two months nobody remembers what was supposed to be done.
• Goals without context. A number without an explanation of where it came from is ignored by the team.
• Channels chosen out of habit. "We have always done trade shows" is not an argument. The argument is how many clients from trade shows actually bought in the last two years.
• No plan B. The plan assumes everything will go according to assumptions. In B2B, that is almost never the case.
• Measurement at the end. If measurement is not part of the plan from the start, it will be an add-on after the fact and will convince no one.

Another problem is plans that are too vague. "Increase brand awareness" sounds good, but says nothing about what to do on Monday. A marketing plan works like an operating manual for the team. A board presentation is a secondary function.

How long it takes to write a marketing plan

A realistic timeline is two to four weeks if the data is available. The first week is for the audit and conversations. The second is for working on the objective and structure. The third and fourth are for refining the actions, budget, and measurement. If the data has to be collected from scratch, add another two weeks.

It is worth publishing a draft after two weeks and giving the team a week for comments. A plan written in a closed room will have just as many mistakes as one written in a hurry, you will just discover them later.

Finally, something rarely mentioned: a marketing plan does not have to be perfect. It has to be good enough to start and flexible enough to change when the market responds. The best plans we have seen were ugly, short, and full of handwritten notes. The worst were beautiful and nobody used them. A plan created this way has a chance to survive longer than two weeks.
