Small and mid-sized B2B companies usually turn to outsourced marketing at one of two moments. The first is when the company is already running marketing - paying for ads and publishing content - but the leads coming in do not turn into new sales conversations. The second is when the company grows faster than its communication, and the website, sales materials and ways of winning clients are a few years behind.
In a company of twenty to one hundred and fifty people the picture is often similar. Marketing is handled by the CEO after hours, by a salesperson between meetings, or by one person who on the same day writes a LinkedIn post, orders trade fair materials, fixes the website and puts together a client presentation. On top of that there are several external providers - an agency running Google Ads, a freelance designer, the software house that once built the website. Everyone does their part, but nobody is responsible for the whole. The problem is rarely a lack of activity - more often it is a lack of direction and coordination across all communication.
In this article I explain what outsourced B2B marketing involves, from a perspective I know from both sides: for ten years I looked after clients as an Account Manager in agencies, and for four years I was responsible for lead-focused marketing as a Marketing Manager on the client side. I cover the scope of the service, cooperation models, costs, how to measure results and the questions worth asking along the way.
Outsourced B2B marketing in a nutshell
Outsourced marketing means an external specialist or team runs a company's marketing on an ongoing basis - from the audit and strategy, through the website, content and campaigns, to lead generation and reporting. In a small or mid-sized B2B company it replaces or supports an in-house marketing team. The key point is that one person or one team is responsible for the whole and for marketing's impact on sales.
Well-run outsourced marketing always has five elements:
Diagnosis. An audit of current activities, data and materials before any proposal is made.
Strategy. Who we talk to, what we say, in which channels, on what budget and how we will know it works.
Execution. Website, content, campaigns, sales materials and tools, delivered according to the plan.
Measurement. Metrics linked to sales, not just reach.
Regular review. Adjusting activities based on results, not gut feeling.
What is outsourced B2B marketing and how is it different from buying individual services?
Outsourced marketing means that an external specialist or team takes responsibility for a company's marketing as a whole: sets priorities, plans activities, runs them directly or with providers, and is accountable for results. It is often described as an external marketing department.
The difference from buying individual services is fundamental. When a company orders "social media management" or "a Google Ads campaign", the provider is responsible for one channel and reports on that channel's metrics: number of posts, reach, clicks. Nobody asks whether the channel is right at all for a company that sells, for example, automation systems for manufacturing plants. With outsourced marketing the starting point is the business goal, and channels are chosen to serve it.
Full-service or partial outsourcing?
Full-service outsourced marketing covers every area: strategy, website, content, campaigns, tools, sales materials and reporting. Partial outsourcing focuses on the area that is holding the company back most today, for example lead generation or a website rebuild. Small B2B companies often start with a partial scope and expand it once the first activities deliver results. That is more sensible than launching eight channels at once on a budget that is enough for two.
Why do small and mid-sized B2B companies outsource marketing?
B2B marketing works differently from consumer marketing. Purchasing decisions are usually made by several people: management, the technical team, procurement, finance. The process takes weeks, and for large implementations even several months or more than a year. The number of companies that could ever become clients is sometimes limited to a few hundred in a whole country. In these conditions, tactics built for mass reach do not work. What is needed is strategy, patience and consistency.
Outsourced marketing is most often used by companies where:
marketing is done "on the side", by the CEO, salespeople or an executive assistant, in whatever time is left after other duties;
one person is responsible for everything, from strategy to ordering branded merchandise, and has neither the time nor the experience to set priorities;
activities are spread across several providers who do not talk to each other, and the company pays for channels without knowing what it gets from them;
a big change is coming: a new product, entry into a new segment, a website rebuild, a rebrand;
there is nobody who talks to the board in terms of results, rather than likes.
There is also a purely organisational argument. Full B2B marketing requires several different skill sets: strategy, content creation, paid campaigns, SEO, analytics, design and marketing automation tools. A small company will not hire five specialists, and one in-house employee rarely masters all of these at a high level. Outsourcing gives access to these skills at the scale the company actually needs.
What does outsourced B2B marketing include?
The scope depends on the company's starting point, but most projects cover the same areas. More important than the list is the order: there is no point launching a campaign that drives traffic to a website without a clear offer and a working contact form.
Marketing audit
Every engagement should start with an audit of what the company is already doing and with what results. This covers the website (where visitors come from, which pages lead to enquiries, whether the forms work at all), active channels and campaigns, CRM and analytics data, existing sales materials and competitors' offers.
One source of knowledge is often overlooked, yet it is invaluable: talking to the people who sell. Salespeople know what clients ask about, what objections they raise and at which stage they most often drop out. The result of the audit is a written diagnosis with priorities: what works and should continue, what to stop, what to change and where to start.
B2B marketing strategy
The strategy turns the diagnosis into a plan. It is built on target groups and personas: the industry, size and situation of the companies that are ideal clients, and the people involved in the buying decision and their motivations. Then come the value proposition, messaging, channels, timeline, budget and KPIs.
A good strategy for a small or mid-sized company does not need to run to eighty pages. It should be a decision-making tool: when someone proposes a trade fair or a new campaign, the team should be able to check whether it fits the strategy or not.
The website as your best salesperson
In B2B, buyers usually get to know a company on their own before they get in touch: they read the website, compare offers, look for reviews and examples of past work. The website therefore works like a salesperson available around the clock. Within seconds it has to answer: what the company does, for whom, what makes it different and how to get in touch.
With outsourced marketing the website is developed continuously: new service pages answer specific client queries, case studies are added, forms and contact paths are improved. One example of this approach is the Reequest Events website project described in my portfolio: I started with an audit and communication strategy, wrote the content, prepared the SEO strategy and led creative oversight of the design and the Webflow build.
Content marketing, SEO, GEO and AEO
Content marketing that answers clients' real questions is one of the most effective ways to build trust in B2B before the first conversation. This means expert articles, guides, solution comparisons, case studies and downloadable materials. Each piece of content should have a clear job: attract search traffic, answer an objection or help a salesperson in a conversation.
In B2B, SEO is best started with keywords that show purchase intent, such as a service name combined with an industry or city, rather than the most popular informational queries. Alongside SEO, companies now need GEO (Generative Engine Optimization) and AEO (Answer Engine Optimization), which means making sure the company appears in AI-generated answers: in Google's AI Overviews, ChatGPT, Perplexity or Gemini. Some decision-makers now start looking for a provider by asking an AI assistant rather than scanning a list of search results. Visibility in these answers comes from content with clear, self-contained answers to specific questions, FAQ sections, structured data, a consistent company description across many sources and mentions in industry media. In practice, SEO, GEO and AEO are one content strategy, not three separate projects.
Lead generation and advertising campaigns
Lead generation is usually the most important goal of outsourced B2B marketing. What counts, however, is not the number of contacts but how many of them move through the stages of the sales funnel all the way to a signed contract.
In B2B paid advertising, two channels usually work best. Google Ads reaches people who are already looking for a solution and typing specific queries. LinkedIn Ads targets people precisely by job title, industry and company size, which matters a great deal with a narrow audience, although the cost per click is noticeably higher than in other channels. These are often complemented by retargeting people who have already visited the website, and by lead magnets: checklists, e-books or webinars offered in exchange for contact details.
At Medidesk, a healthcare software company where I led B2B marketing from 2019 to 2023, the combination of Google and LinkedIn campaigns with webinars and expert content was the foundation of lead generation for the sales team.
Marketing automation and CRM
Marketing automation makes it possible to nurture a potential client without manual work on every email: after downloading a resource, the client receives a series of messages tailored to their interests, and the salesperson gets a signal when the contact is ready to talk. This requires a well-maintained CRM (small and mid-sized companies often use Pipedrive or HubSpot).
The most important work in this area is not technical, though. Marketing and sales have to agree on what counts as a lead. A split into MQLs and SQLs helps, together with clear criteria for when a contact is handed over from marketing to sales. Without this definition, marketing reports hundreds of leads, sales says it gets no valuable contacts, and both are right.
Sales materials
Outsourced marketing also covers the tools salespeople use: the company presentation, the proposal template, case studies, a one-pager summarising the offer, and materials for trade fairs and meetings. In many companies these materials are the weakest link: the website has been refreshed, but salespeople still send a five-year-old presentation with the old visual identity and an outdated offer.
Events, webinars and conferences
In B2B, events are one of the most effective ways to build client relationships and an expert position. A webinar reaches several hundred people from an industry at low cost and collects contacts. Your own conference or a meeting for key clients gives you several hours of decision-makers' attention in one place. At Medidesk I ran, among other things, industry conferences for healthcare managers that combined brand building with lead generation.
Events make sense when they follow from the strategy and are connected with other activities: invitations, campaigns and follow-up with attendees after the event. I write more about types of events and how they are produced in my article on B2B event marketing.
Reporting and optimisation
The last, ongoing element is regular reporting and adjustment. A report should answer simple questions: how many enquiries there were, where they came from, what sales did with them, how much they cost and what we change next month. A report that shows only reach and impressions does not let the board judge whether the money spent on marketing is working.
What an external partner will not do for you
An honest conversation about outsourced marketing should also cover its limits. An external specialist can put marketing in order, but cannot replace a few things that remain on the company's side:
A competitive offer. Marketing will not sell a product that loses to competitors on price, quality or terms, but it can quickly show that the problem lies in the offer rather than the communication.
An effective sales process. A lead that a salesperson calls back a week later is effectively lost, so a good rule is to respond within one business day.
Management's time and knowledge. Expert content requires knowledge that the company has, not the provider. It is worth assuming that a decision-maker will spend one to two hours a week on the cooperation: meetings, approvals and supplying materials.
Time for results. Paid campaigns can bring the first enquiries within a few weeks, but SEO, GEO and content marketing in B2B usually need six to twelve months to work at full strength.
Outsourced marketing models: agency, freelancers, fractional marketing manager or in-house hire?
Outsourced marketing can be organised in several ways. Each model has its strengths and limits, and the choice depends on the size of the company, the budget and whether the company mainly needs direction or execution capacity.
Marketing agency
A full-service agency gives access to a team: a strategist, copywriters, designers, campaign and SEO specialists. That means strong production capacity and a wide range of skills under one roof.
I know the limits from experience, because I spent ten years on the agency side. The client usually deals with an account manager who passes tasks on and is not always a strategist. An agency naturally recommends the services it delivers itself. Team turnover also means that the people who know the client's business change every year or so. For a small company with a modest budget this is often the most expensive option, and the company may be one of dozens of clients.
Freelancers and specialist providers
Outsourcing individual tasks to freelancers (a designer, a copywriter, a Google Ads specialist) is flexible and usually cheaper. The problem is coordination: someone has to decide what should be created, in what order and why, and then check the results. In practice this role falls to the CEO or sales director, which brings us back to marketing done "on the side".
Fractional marketing manager
A fractional (external) marketing manager is one experienced person who acts as the company's head of marketing without a full-time contract. They diagnose, build the strategy, set priorities, manage providers or the client's team and report results to the board. Because they do not sell their own production, they can objectively assess agency proposals, write briefs for them and check the results of their work.
This is the model I work in as part of my marketing consulting: I take responsibility for direction and coordination, and delegate execution to trusted specialists or to the client's own team. The limit of this model is obvious: one person cannot deliver all production tasks alone, so you need providers or someone in the company to implement the plan.
In-house marketing team
Hiring a full-time marketer gives you someone who knows the company from the inside and is available on site. On top of the salary, however, there are employer costs, tools, training, recruitment and onboarding time.
The biggest limitation is not financial, though. A single in-house specialist rarely combines strategic and hands-on skills across all channels, and in a small company there is no manager to guide their marketing work.
Hybrid model
In many companies with thirty to two hundred employees, a combination works best: an in-house specialist or junior specialist handles day-to-day execution, while a fractional marketing manager spends a few days a month setting direction, planning, running the more complex projects and reviewing results. The company gets both continuity and strategic experience without paying for a full-time director.
Marketing agency: priorities set by the agency's account manager and strategist, fixed cost: high. Works best when the company needs strong production capacity across many channels.
Freelancers: priorities set by the company (usually management), fixed cost: low. Works best when the company has someone who can coordinate providers.
Fractional marketing manager: priorities set by the marketing manager together with management, fixed cost: medium. Works best when the company needs direction, strategy and coordination.
In-house marketing team: priorities set by the employee or management, fixed cost: salaries that grow with the team. Works best when the company is big enough for a small team with a leader.
Hybrid model: priorities set by the fractional marketing manager, fixed cost: medium. Works best when the company has someone to execute but lacks a leader.
How much does outsourced B2B marketing cost?
The cost depends on the scope, the number of channels and the intensity of activities, so a reliable quote is only possible after an initial conversation or audit. It is still worth knowing what the budget consists of, because offers on the market combine these elements in very different ways.
A B2B marketing budget usually has three layers:
Fees for the work. Most often a fixed monthly retainer for a defined scope, or hourly billing. The audit and strategy are usually priced as separate, one-off projects.
Media budget. Money spent directly in advertising platforms: Google, LinkedIn, Meta. It should be clearly separated from the provider's fee, so the company knows how much it pays for advertising and how much for managing it.
Production and tools. Photo shoots, video, website design or rebuild, CRM licences, an email marketing platform, analytics tools.
One rule is non-negotiable for me: ad accounts, analytics, the domain and the CRM are registered to the client's company, and the provider is given access. If the cooperation ends, the company keeps its full campaign history and data instead of starting from scratch.
A good way to start working together is an audit and strategy as a separate project. The company receives a concrete document with priorities that it can implement on its own or with the same provider, and both sides see how well they work together before committing to ongoing support.
How does outsourced marketing work, step by step?
Cooperation usually runs in six stages. This is how it looks in my projects:
Initial call. A short, free 15-20 minute conversation about the company, its clients, sales goals and what is not working today. We agree on the scope and form of cooperation.
Audit and materials. A review of the website, channels, campaigns, CRM and analytics data and existing materials, plus conversations with the people who sell.
Diagnosis and recommendations. A written summary: what works, what to stop, what to change, with clear priorities.
Strategy and action plan. Channels, messaging, timeline, budget and the KPIs we will use to assess results.
Execution or oversight. Either the company's team implements the plan while I keep it on course, or I run the implementation with providers.
Results review. After an agreed period we compare results with the plan and adjust activities.
Over time it looks roughly like this. The first one to three months are the audit, strategy and putting the foundations in order: the website, analytics, CRM and sales materials. Between the third and sixth month activities become regular, and ongoing tests show which channels and messages bring the best enquiries. From around the sixth month you can scale what works and drop what does not.
It is worth agreeing the rhythm of cooperation at the start: a short working meeting every week or two, a monthly report and a quarterly strategy review with management.
How do you measure the results of outsourced B2B marketing?
Results in B2B are measured with metrics linked to sales, not just visibility. Followers or impressions can be a useful signal, but they do not tell you whether marketing is contributing to the company's results.
The most important metrics are:
the number of qualified enquiries and their sources, meaning which channels bring contacts that match the client profile;
cost per lead in each channel;
conversion at each stage: from enquiry to meeting, from meeting to proposal, from proposal to contract;
the value of sales opportunities in the CRM, meaning the pipeline generated by marketing;
search traffic to service pages and rankings for keywords with purchase intent;
meetings and conversations booked after events and webinars.
Companies with well-organised CRM data can also calculate the ROI of their marketing. In a small company, however, a simple report in which marketing and sales look at the same numbers is enough to start with.
How do you choose an outsourced marketing provider?
Before signing a contract, it is worth asking a few questions that quickly show whether a provider sees marketing as a sales tool or as a list of services to tick off:
Who exactly will run our project, and what B2B experience do they have?
Where will you start, and what will we have after the first month?
Which metrics will we use to judge results, and how often will you report?
Will you talk to our salespeople and clients?
Whose name will the ad accounts, analytics and tools be registered in?
What do you need from us: how much time, which approvals, which materials?
What is the notice period, and what happens to the materials when the cooperation ends?
Warning signs matter just as much. Be careful when a provider guarantees a specific number of leads or the top position in Google, offers a package of "X posts a month" before seeing any data, runs campaigns on its own accounts without handing over access, reports only reach, or proposes a one- or two-year contract with no option to end the cooperation earlier.
The most common mistakes when outsourcing marketing
Starting with channels instead of goals. The decision that "we have to be on TikTok" is made before answering where the decision-makers the company wants to reach actually are.
No shared definition of a lead. Marketing and sales judge results by different criteria and cannot agree.
Expecting results after one month. In B2B the first three months are usually spent putting the foundations in order, and full results come later.
Marketing cut off from company knowledge. A provider without access to the company's experts and salespeople produces generic content that any company in the industry could publish.
Too many channels at once. It is better to run two channels well than six badly.
Summary
Outsourced B2B marketing makes sense when it starts with a diagnosis and a sales goal, and channels, content and campaigns are chosen to fit the strategy rather than the other way round. For a small or mid-sized company, the key is that one person or one team is responsible for the whole, reports results in the language of sales and adjusts activities based on data. The cooperation model - agency, freelancers, a fractional marketing manager, an in-house hire or a combination - should match what the company lacks more: direction or execution capacity.
After years of working on both sides of the table, I am convinced of one thing: B2B marketing does not need more activities, it needs better decisions about which of them really support sales.
FAQ: frequently asked questions
What is outsourced B2B marketing?
Outsourced B2B marketing means an external specialist or team runs a company's marketing on an ongoing basis. It covers the audit, strategy, website, content, campaigns, lead generation and reporting. In small and mid-sized companies it replaces or supports an in-house marketing team.
What does full-service outsourced marketing include?
Full-service outsourced marketing covers every area of marketing: audit and strategy, the website, content marketing, SEO, GEO and AEO, advertising campaigns, marketing automation and CRM, sales materials, events and webinars, and regular reporting. Partial outsourcing focuses on one or a few of these areas, usually the one that is holding sales back most.
How much does outsourced marketing cost for a small business?
The cost depends on the scope, the number of channels and the intensity of activities. The budget consists of fees for the work (usually a monthly retainer), the media budget spent in advertising platforms, and production and tool costs. A reliable quote can be prepared after an initial call or audit, and a good way to start is an audit and strategy priced as a separate project.
Is it better to hire an in-house marketer or outsource marketing?
An in-house hire gives you someone on site, but one specialist rarely combines strategic and hands-on skills across all channels, and employer costs, tools and training come on top of the salary. Outsourcing gives access to broader expertise at a scale that fits the company. In many companies a hybrid model works best: an in-house specialist plus a fractional marketing manager who sets the direction.
How long does it take to see results from outsourced B2B marketing?
Paid campaigns can bring the first enquiries within a few weeks of launch. The first three months, however, are usually spent on the audit, strategy and putting the foundations in order, and SEO and content marketing in B2B need six to twelve months to work at full strength. Clear improvements in the number and quality of enquiries usually appear after about six months of consistent work.
What is the difference between outsourced marketing and marketing consulting?
Marketing consulting focuses on direction: diagnosis, strategy and recommendations that the company implements on its own or with chosen providers. Outsourced marketing also includes running activities on an ongoing basis and taking responsibility for their delivery. In practice the two often go together: cooperation starts with an audit and strategy and then moves into ongoing implementation support.
