How to Build a Marketing Function in an Established Business.

Building marketing in an established business is different from building marketing in a start-up. The company already has customers, a reputation, salespeople, suppliers, documents, a website, historical ways of doing things and people who have taken on marketing tasks informally.

The job is therefore not to start from zero. It is to turn scattered activity into a deliberate function without disrupting what already works.

The best starting point is governance and clarity, not hiring a social media person or buying another marketing service.

Established business

Do not start from zero.

The task is to turn scattered activity into a deliberate function without disrupting what already works.

10-step build

Build the operating system before buying more channels.

The sequence moves from visibility and ownership to customer journey, foundations, channels, budget and reporting.

Step 1: Audit what already exists

Start by mapping the current state. List the customer-facing assets, channels, suppliers, events, templates, internal owners, recurring requests and marketing spend already in the business. Review the website, company profile, sales deck, proposal templates, social channels, paid media, SEO, newsletters, email signatures, event material, customer communications and any brand standards.

Also identify the less obvious activity: who updates PowerPoints, who briefs the stand builder, who manages the web developer, who creates customer notices and who reports marketing to management. The audit usually reveals that the business already has a marketing function in practice; it is simply not organised as one.

Step 2: Define the business and sales priorities

Marketing should not begin with channels. It should begin with the company’s commercial priorities. What does the business need to grow?

Which services or products matter most? Which sectors or customer types are strategic? Is the priority new-logo acquisition, retention, cross-sell, geographic expansion, reputation, recruitment or stronger sales conversion?

These priorities determine what marketing should focus on. A company trying to grow existing enterprise accounts needs a different plan from one trying to enter a new region.

Step 3: Assign ownership

Someone must own the function. That may be an internal marketing leader, an executive sponsor plus an external department, or another clearly defined structure. The owner needs authority to set priorities, coordinate suppliers, request input from sales and operations, manage the budget and report to management.

Without that authority, marketing remains a service desk that reacts to the loudest request. Decision rights should also be clear. Sales owns commercial negotiation.

Technical teams own technical accuracy. Finance owns payment controls. Marketing owns the marketing plan and the presentation of the business.

Step 4: Map the customer journey

Look at how a prospect moves from first awareness to becoming and remaining a customer. Reburn uses Awareness, Interest, Onboarding, Action and Resell as a simple framework. At each stage, ask what the customer sees, what questions they ask, what proof they need, what friction exists and which team owns the next step.

This often exposes the most useful marketing priorities. The website may be fine, but proposals may be weak. Lead generation may be healthy, but onboarding communication may be poor.

Existing customers may receive almost no structured communication about additional services.

Step 5: Fix the foundations

Before scaling campaigns, fix the basics that affect everything else. This may include brand standards, approved logo files, company profile, pitch deck, proposal template, website structure, service descriptions, case studies, email signatures, presentation templates and a central asset library. These assets reduce rework and make every future campaign easier.

They also improve sales confidence and customer perception immediately.

Step 6: Decide which channels and capabilities matter

Only after the business objectives and customer journey are clear should the company decide how much emphasis to place on SEO, Google Ads, social media, email, events, content, PR or other channels. The answer may be different for each service line. A highly specialised B2B service may benefit from a small number of high-intent Google Ads campaigns and strong technical content.

Another business may get more value from executive events, partner marketing and account-based outreach. Channels are tools, not the strategy.

Step 7: Choose the operating model

Decide which capabilities should sit internally, which should be outsourced and who will coordinate the whole system. A simple structure might be an internal marketing coordinator supported by Reburn and specialist vendors. Another company may use Reburn as the primary marketing function.

A larger business may build an internal team and retain agencies for technical depth. The operating model should match workload and economics, not fashion.

Step 8: Build the budget

Create a budget that separates baseline marketing operations from variable spend. Baseline costs may include department or staff costs, software, design capacity, website maintenance, SEO and recurring content. Variable costs may include paid media, expos, photography, video, major print runs, sponsorships and one-off projects.

This gives management a clearer view than one large “marketing” number and makes trade-offs easier during the year.

Step 9: Create a reporting rhythm

Decide what marketing will report monthly or quarterly. Keep the management view focused on objectives, spend, pipeline contribution where measurable, sales-support work, major projects, events, risks, supplier performance and next decisions. Specialists can still provide detailed reports, but the marketing function should translate them into one coherent management view.

Step 10: Build a 90-day roadmap

The first 90 days should focus on a small number of high-impact priorities rather than trying to fix everything at once. A practical first quarter may include: completing the audit, assigning owners, fixing the most urgent brand or sales assets, creating a budget, agreeing the reporting format, improving one or two major customer touchpoints and setting the next campaign or event plan. The goal is visible progress plus a repeatable operating rhythm.

Year one

A first-year roadmap.

The first year should usually move through three broad phases. Foundation: audit, standards, ownership, sales assets, website gaps, reporting and budget. Build: campaigns, channel development, events, content, case studies, customer communications and supplier optimisation.

Improve: review performance, improve conversion and customer experience, strengthen account growth and remove recurring operational friction. The exact sequence should remain flexible. A major expo, tender season or website rebuild may change priorities.

When everything feels urgent

How to sequence the work when everything feels urgent

Established businesses often discover dozens of gaps during the first audit. The temptation is to create a very large marketing plan and start everything at once. That usually produces slow progress and internal fatigue.

A better approach is to rank work using four questions. Commercial impact: does this directly affect sales, customer trust or a major strategic objective? Urgency: is there a fixed deadline such as an expo, tender or launch?

Dependency: does other work rely on this being completed first? Effort: can the business deliver it with the people, budget and information currently available? A proposal template that affects every new opportunity may outrank a brand video.

Fixing website architecture may need to happen before a major SEO content programme. Building an approved servicedescription library may need to happen before several sales sheets can be created. This sequencing prevents the marketing function from becoming a backlog of disconnected requests.

First quarter

A realistic first 90 days.

In the first month, focus on visibility and control: supplier map, asset inventory, budget baseline, priority customer journeys, sales interviews and the most obvious brand or website risks. In month two, fix the foundational items that create leverage: core messaging, sales templates, brand standards, reporting and the first priority content or website changes.

In month three, move into a repeatable rhythm: campaigns, events, channel optimisation, case-study production and a forward calendar. The point of the first 90 days is not to “finish marketing”.

It is to prove that the new function can make decisions, close obvious gaps and establish a rhythm that the business can sustain.

Avoidable mistakes

Common mistakes

The first mistake is hiring for one channel before deciding who owns the function. The second is creating a long strategy document with no owners or budget. The third is trying to launch every channel at once.

The fourth is ignoring sales input. The fifth is assuming the existing website and collateral are “good enough” without testing them against the current business. The final mistake is over-engineering governance.

The system should make marketing easier to manage, not create another layer of bureaucracy.

What to avoid in year one

Do not let the first year become a permanent rebrand project. Do not spend the entire budget on one visible campaign while basic sales tools remain weak. Do not appoint several new suppliers before deciding who will manage them.

And do not measure progress only through digital dashboards. A first-year marketing function should become more useful to sales, more visible to management and easier to operate across the business.

FAQs

Frequently asked questions.

Should we hire first or plan first?

Plan and define ownership first. Otherwise the first hire is likely to become a generalist who inherits every marketing task without clear priorities or enough specialist support.

What should happen in the first 90 days?

Audit the current state, define commercial priorities, assign ownership, fix urgent foundations, establish the budget and reporting rhythm, then begin the highest-priority execution work.

Do we need every marketing channel?

No. Use the channels that support the commercial strategy and customer journey. A smaller number of well-managed channels is usually better than broad activity with no ownership.

Can we build the function gradually?

Yes. In fact, established businesses often benefit from phased implementation because the audit reveals which foundations need to be fixed before more spend is added.

Practical starting point

Start with five questions, not a shopping list of services.

If you are building the function now, do not begin by asking which marketing service to buy. Begin by answering five questions: What are our commercial priorities?

Who owns marketing? What already exists?

Where is the customer journey weak? What should we fix in the next 90 days?
