What’s the difference between a marketing plan and a business development plan?
It’s one of those questions that comes up time and time again in professional services firms: where does marketing end and business development begin?
You’re not alone if you’ve found yourself wondering whether you need two separate plans, one combined document, or if it even matters. But understanding the difference between these two approaches is absolutely essential if you want both to work effectively for your firm.
When firms blur the lines between marketing and business development, marketing activity can end up feeling completely disconnected from revenue goals. And when BD efforts don’t draw on marketing support, opportunities slip through the cracks.
In this blog, I’m going to break down the key differences between these two types of planning and show you exactly how they should work together to support your firm’s growth.
Marketing plan vs business development plan: the simple version
At a high level, here’s how it breaks down:
Marketing creates awareness, builds visibility and positions your firm in front of the right audiences. It’s about getting noticed and remembered for the right reasons.
Business development focuses on building relationships and converting that awareness into new instructions or retained work. It’s about turning interest into action.
But that’s only the beginning of the story.
What a marketing plan includes
A marketing plan is designed to support firmwide visibility, reputation and positioning. It creates the conditions that make it easier for your firm to be found, trusted and remembered when potential clients need your services.
A strong marketing plan will cover:
Target audience clarity – You need to know exactly who you want to reach and influence. This means going beyond ‘businesses in our area’ to understand the specific types of clients who are most likely to need your services and can afford to pay for them.
Positioning and messaging – What do you want to be known for? This is about defining what makes your firm different and why clients should choose you over your competitors. It’s not just about what you do, but how you do it differently.
Channels – How will you reach people? This might include LinkedIn, email marketing, search engine optimisation, events, speaking opportunities, or industry publications. The key is choosing channels where your target audience actually spends their time.
Content and campaigns – What will you say and when will you say it? This involves creating a content calendar that addresses the questions your prospects are asking and demonstrates your expertise in a way that builds trust.
Brand assets – This includes things like your website, marketing collateral, email templates, and tone of voice. All of these need to work together to create a consistent impression of your firm.
Measurement – How will you know if it’s working? This might include tracking engagement rates, reach, brand recall surveys, website visits, and enquiries generated.
The goal is to create structured, sustained visibility that opens the door for business development conversations to happen naturally.
What a business development plan includes
A business development plan is more focused and is often built around individual partners, service lines or sectors. It’s about proactively pursuing opportunities and turning conversations into revenue.
It typically includes:
Targets and objectives – What are your specific revenue goals or new client acquisition aims? These need to be realistic but ambitious enough to drive growth.
Client and prospect lists – Who are you actively pursuing? This should include both new prospects and existing clients where there are opportunities to expand your relationship.
Relationship mapping – Who knows who, and where does influence lie? Understanding the decision making process and key influencers in your target organisations is crucial for effective business development.
Tactics – What specific activities will you undertake? This might include meetings, follow up calls, networking events, introductions, and proposal presentations.
Proposal support – How will you present your firm when opportunities arise? This includes having ready access to case studies, service descriptions, fee structures, and differentiators that set you apart.
Cross selling opportunities – How can you deepen existing relationships? Often the easiest new business to win is additional work from clients who already trust you.
Measurement – How will you track progress? This might include pipeline movement, instructions won, conversion rates, and the value of new business generated.
It’s about turning visibility into concrete action that leads to new instructions.
Where things go wrong
Many firms create a marketing plan but neglect to build a proper BD plan, relying instead on ad hoc partner activity with no real structure or accountability.
Others treat marketing and BD as completely separate functions with little communication between them, which inevitably leads to misalignment and missed opportunities.
This disconnect can show up in several ways:
Marketing might be successfully building awareness, but no one is following up on the enquiries or interest that’s being generated. Potential clients slip away because there’s no system for converting interest into conversations.
Alternatively, partners might be actively chasing leads and trying to build relationships, but they’re doing so without proper brand or messaging support. This makes it harder to stand out and can result in inconsistent messages being delivered to the market.
You might find that your firm has poor visibility in key sectors because marketing efforts aren’t aligned with the areas where business development is most focused.
Referral opportunities and warm leads can go cold because there’s no proper handover process between marketing activity and business development follow up.
How marketing and business development should work together
The most effective firms align both functions around a shared goal: building trust with the right clients and generating quality work that’s profitable and enjoyable.
That means marketing sets the stage with strong positioning, compelling content and sustained visibility in the right places. This creates the foundation that makes business development conversations easier and more productive.
Business development then builds on this foundation by actively pursuing relationships, following up on interest, and nurturing leads through the decision making process.
But it’s not a one way street. Marketing should actively support business development efforts by providing assets, messaging, and market insight that makes BD activity more effective.
And business development should feed back intelligence from the market so that marketing stays relevant and continues to address the questions and concerns that prospects are actually expressing.
You don’t necessarily need two separate teams if you’re running a smaller firm, but you absolutely do need both types of planning to happen in a coordinated way.
Making it work in practice
Start by ensuring your marketing and business development plans are built around the same target clients and objectives. If marketing is focused on one type of client and BD is chasing completely different opportunities, you’re working against yourself.
Create clear handover processes so that enquiries generated through marketing activity are properly followed up. This might involve setting up systems for lead tracking and ensuring someone has clear responsibility for converting interest into conversations.
Make sure your business development team has easy access to marketing assets that support their conversations. This includes case studies, service descriptions, thought leadership content, and proposal templates that reflect your positioning and messaging.
Schedule regular communication between marketing and business development so that insights and feedback flow both ways. Marketing needs to understand what’s happening in the market, and BD needs to know what marketing activity is planned so they can capitalise on it.
Final thought
If you’re relying solely on a marketing plan, or expecting business development to happen without one, you’re likely missing out on significant opportunities. And if your plans aren’t properly aligned, your firm is essentially pulling in different directions.
The best approach is to create two focused plans that work together as part of one joined up strategy. When marketing and business development are properly aligned, each makes the other more effective, and the result is sustainable growth that feels manageable rather than chaotic.
The question isn’t whether you need both types of planning. You do. The real question is how well you’re going to make them work together.
