Marketing Without an Agency: What a Small Business Can Do Itself

Can a small business do marketing without an agency?

For many owners, marketing has only two states. Either an agency takes care of it, or nothing happens. The agency is expensive, so usually little happens. The website stays unchanged for three years, the business profile is not maintained, and the most recent testimonial dates from the year the company was founded.

This guide therefore answers the question: Which marketing tasks can a small business take on itself, which should it buy in, and how much time does that take per month? We first clarify the terms and transfer a model from economics to marketing. Then we look at what studies show about small businesses, weigh two views and finally build a monthly program with hours.

The most valuable part of a small business’s marketing is something no agency can supply: knowing why customers buy.

Terms: in-house work, buying in and the hybrid

In-house work in marketing means that the owner or employees plan and carry out a task themselves, such as writing an expert article or answering reviews. Buying in means an external provider takes it on: an agency, a freelancer or a photographer. In between is a hybrid, which is what works most often in small businesses: the business supplies content and decisions, the external party supplies craft, such as technical setup or copyediting.

The question is the same as for any other service in the business, as the article on make or buy describes. You do not compare two prices but two total costs. In-house work includes the working time that is missing elsewhere. Buying in includes, besides the fee, the costs of searching, coordinating and checking.

The thinking model: transaction cost theory in three questions

Transaction cost theory goes back to Ronald Coase and was elaborated by Oliver Williamson. Its basic idea: every exchange in the market causes costs beyond the price, namely for finding the partner, for negotiating and for checking whether delivery is as agreed. Three questions follow from this. How specific is the task to the business, how uncertain is it, and how often does it occur? The higher the answers, the more doing it in-house pays off.

Applied to marketing, this means: a task is specific if it requires knowledge about your own customers, services and cases that an outsider would first have to acquire with effort. It is uncertain if it is hard to define in advance what exactly should come out and hard to check the result. It is frequent if it occurs every week or every month. An expert article on a typical customer question is specific and frequent; it belongs in-house. Setting up web analytics is not very specific and rare; it can easily be bought in.

I call this classification the marketing task grid. It does not replace a calculation, but it organizes the discussion. Anyone who goes through each row once with their team usually sees that more than half of the ongoing work is specific and frequent.

What studies show about marketing in small businesses

There is little research on how small businesses decide between in-house work and buying in for digital marketing. McCartan (2026) conducted more than 30 semi-structured interviews in small businesses from various industries in one region of the United Kingdom. The businesses were selected so that all combinations occurred, from doing everything in-house to outsourcing everything. The author describes the decisions using two logics from research on entrepreneurs: effectual logic, which starts from the means at hand, and causal logic, which plans from a goal. More on this is in the article on effectuation.

The finding is instructive for owners. Effectual logic usually dominated: you start with what you have and can do. But for a business to actually make a change, such as bringing a task back in-house or outsourcing it, causal thinking was needed. And only where businesses explicitly connected their marketing goals to their business goals did the measures serve those goals better. Triggers for change were common, but they were also overlooked. The study is qualitative and regional; it shows patterns, not frequencies.

An interview study of owners of small accommodation businesses in South Africa adds to the picture (Thwala and Slabbert 2026). Almost all respondents lacked marketing training, dedicated staff and a planned strategy. They used inexpensive digital platforms but hardly made use of their measurement options. The most effective advertising remained word of mouth. This, too, is a small, industry-specific sample. But both studies point in the same direction: what is missing is rarely willingness, but rather goals, time and measurement.

There is also quantitative evidence for the core of the model, though from accounting. Everaert, Sarens and Rommel (2010) found among Belgian small and medium-sized enterprises that frequent and specific tasks were outsourced less often, and that the owner’s trust in the external partner played a role.

Do it yourself or hire an agency? Two views

The first view argues for the agency. Professionals know the tools, know what has worked in other industries and work faster. An owner who learns their way around ad accounts and analytics tools spends hours on things a professional does in minutes. Then there is reliability: the agency delivers even when the business is at peak workload.

The second view argues for in-house work. What convinces in a small business’s marketing is expertise, real cases and recognizable people. These raw materials are in the business. An agency first has to ask for them, and that costs coordination, in other words transaction costs. Anyone who does not supply them gets generic copy that would fit any competitor just as well.

I consider the hybrid the sounder answer, with a clear rule: content in-house, craft from outside. What is specific and frequent, the business does itself. What is rare and technical, it buys in, as a bounded project with a handover. Anyone hiring an agency should ask the questions from the article on choosing an agency and start with a good agency brief.

How much time does marketing without an agency take?

The most common concern is time. But a basic program for a small B2B business can be expressed in hours. The following worked example adopts the guide values from other articles: 15 minutes a week for the business profile, 20 minutes a day for LinkedIn and 30 minutes for the monthly review.

Just under 20 hours a month is about one hour per working day. That is not little, but it is plannable. The costs lie in working time, not in fees. Anyone who values these hours at their hourly rate can compare them honestly with an agency proposal.

The monthly program: how to organize it

For the program to hold, it needs structure. The article on the one-page quarterly marketing plan describes it with at most three measures and fixed if-then appointments. Five steps are enough to get started.

1. Set a goal in orders

   How many inquiries and orders should marketing bring in this quarter? Without a goal, no task can be chosen sensibly.

2. Place tasks in the grid

   Rate each task by the three questions and decide: in-house, hybrid or bought in.

3. Assign responsibilities

   For each task, one person by name, not “the team.” The owner takes on what only they can do.

4. Put appointments in the calendar

   Fixed blocks, such as two hours every Tuesday for the expert article and 15 minutes every Friday for reviews.

5. Measure monthly

   Inquiries per source and what became of them, following the measurement chain from the article on measuring marketing success.

Success is measured in orders, not reach. The measurement chain with the links visit, inquiry, conversation and order is described in the article on measuring marketing success. After a quarter it shows which tasks pay off and which only keep people busy.

What follows beyond the individual case

The decision between agency and in-house work is often treated as a question of budget. It is more a question of responsibility. A business that outsources its marketing completely also gives away the knowledge of what works. A business that does everything itself forgoes outside experience. Anyone who keeps the specific tasks in-house keeps control over what convinces their customers and can use outside help specifically where it brings more than it costs.

The limits of this guide lie in the evidence. The studies on small businesses’ marketing decisions are qualitative and regional; the quantitative evidence for the model comes from accounting. The hours in the worked example are guide values, not measurements. The logic is robust: specific and frequent tasks tend to belong in-house.

Conclusion and next steps

The question was
marketing tasks a small business can take on itself, which it should buy in and how much time that takes. It can take on everything that requires knowledge of its own customers and occurs regularly: expert articles, testimonials, business profile, reviews and the owner’s personal visibility. It should buy in rare and technical tasks, as a bounded project. In the worked example, the basic program needs just under 20 hours a month. Without an agency, much is possible; without a calendar, nothing is.

• List all marketing tasks of the last three months, including those left undone.
• Classify each task by the three questions: specific, uncertain, frequent.
• For each task that stays in-house, enter a responsible person.
• Create two fixed appointments in the calendar: one for content, one for profile and reviews.
• Check whether every inquiry keeps its source.
