I wrote my first business plan when I was starting my agency. It was 22 pages long. It had a market analysis section, a competitive landscape section, a SWOT analysis, and financial projections going out five years. I spent two weeks on it.

I never looked at it again. Not once. It sat in a folder on my desktop gathering digital dust whilst I got on with the actual work of finding clients and delivering projects.

That 22-page document was a waste of time. Not because planning is useless. Planning is essential. But because the format was wrong. A 22-page document is a university assignment. It is not a tool for running a business.

The business plan that actually worked for me was two pages. One page for where we are going and one page for how we get there. I reviewed it every month, updated it every quarter, and used it to make real decisions. It took an afternoon to write and it ran my agency for 13 years.

Why Traditional Business Plans Fail for Agencies

Agency businesses are not like manufacturing businesses or retail businesses. They change fast. A new client can shift your revenue mix overnight. Losing a team member can reshape your capacity in a week. The market moves, client needs evolve, and what you are selling this quarter might look different from last quarter.

A 20-page plan with five-year projections does not work in that environment because it assumes stability that does not exist. By the time you finish writing it, half the assumptions are already outdated.

The other problem is that long business plans are designed to impress people who are not running the business. Banks. Investors. Grant bodies. They are written for an audience, not for the operator. If you are self-funding your agency (which most are), you do not need to impress anyone. You need a document that helps you make better decisions faster.

The Two-Page Agency Business Plan

Here is the format that works. Two sections. One page each. No padding.

Page 1: Where We Are Going (The Destination)

This page answers four questions:

1. What do we do, for whom, and why do they pay us?

Write this in one sentence. Not a mission statement. Not a vision statement. A plain English description of your business.

Mine was: “We design and build brands and websites for professional services firms in Northern Ireland who need to look established and credible.”

That sentence did more for my business than any mission statement because it told me who to sell to, what to sell them, and what mattered to them. Everything that did not fit that sentence was a distraction.

2. What is the revenue target for the next 12 months?

One number. Total revenue. Break it into monthly targets if that helps, but the headline is one annual figure.

When I was at £400K, my target was £600K. Not £1M. Not “double the business.” A number that was ambitious but credible based on what I could see in the pipeline and the market.

3. What does success look like at the end of 12 months?

Three to five specific outcomes. Not vague aspirations you might achieve one day. Measurable results we can track now.

For example:

Those five lines tell you exactly what you are building. They also tell you what to track.

4. What is the single biggest risk?

Every business has one thing that could derail it. Name it. For us, it was client concentration. For you, it might be founder dependency, cash flow, or reliance on a single service line. Writing it down forces you to face it and plan around it.

Page 2: How We Get There (The Route)

This page answers four more questions:

1. What are the three priorities for this quarter?

These are the three things that, if you do nothing else, will move the business closest to the 12-month targets.

When I was trying to build our revenue, my Q1 priorities were: (1) create a high value service offering with two tiers, (2) pitch these to our top 10 prospective clients weekly, (3) hire an account manager to service current clients.

Three priorities I focused on daily. Everything else was secondary.

2. What does the sales pipeline need to look like?

Work backwards from your revenue target. If the annual target is £600,000 and your average project value is £5,000 with a 25% close rate, you need 480 qualified opportunities over the year. That is 40 per month. That is 10 per week.

Now you know exactly how much sales activity is required. No guessing. No hoping.

Most agency owners have never done the maths around sales. They set a revenue target and then hope the phone rings. But it’s just a number with inputs and we control these.

3. What do we need to invest in?

People, tools, training, marketing. List the investments required to hit the targets, with costs. This is your budget for the year.

Keep it honest. If you need to hire someone at £30,000 and spend £5,000 on marketing, write that down. If the business cannot afford those investments from current cash flow, you either need to phase them differently or adjust your targets.

4. What will we stop doing?

This is the most important question on the entire plan. Every agency has things that drain time and money without contributing to growth. Services that are unprofitable. Clients that are not worth keeping. Activities that feel productive but generate no revenue.

Write them down. Commit to stopping them. The time and energy you free up is what funds your growth.

Reviewing and Updating the Plan

A business plan that sits in a drawer is worthless. Here is the review rhythm that makes it a living document.

Monthly (30 minutes): Check progress against the 12-month targets. Are you on track? Ahead? Behind? Update the pipeline numbers. Note any changes in the market or client base that affect the plan.

Quarterly (half a day): Review and reset the three quarterly priorities. Did you complete last quarter’s priorities? If not, why? Set new priorities for the next quarter based on where you are relative to the annual targets.

Annually (full day): Rewrite the plan. New 12-month targets. New success criteria. New quarterly priorities. Keep the format the same. Two pages. No bloat.

I did my annual plan in December every year. Booked a day out of the office, went to a coffee shop, and spent the morning writing and the afternoon refining. That one day of planning shaped every decision for the following 12 months.

What Most Agency Business Plans Get Wrong

They are too long. If your business plan is longer than two pages, you are writing for someone else. The person who needs to use this document is you. Keep it short enough that you will actually read it every month.

They focus on what you want, not what the market wants. “We want to be a leading creative agency” is not a plan. “We will win 12 new clients in professional services because they are underserved by current agencies in our market” is a plan. The difference is specificity and market awareness.

They have no financial model. A business plan without numbers is a wish list. You need revenue targets, cost projections, and pipeline maths. These do not need to be complicated. A simple spreadsheet with monthly revenue, costs, and profit is enough.

They do not name what to stop. Every new priority requires capacity. If you add without removing, you end up overcommitted and underperforming. The best business plans are as clear about what you will not do as about what you will.

What to Do This Week

  1. Write your one-sentence business description. What you do, for whom, and why they pay you. Spend 15 minutes on it. If you cannot get it into one sentence, your positioning needs work.

  2. Set your 12-month revenue target. Be honest. Base it on current run rate, pipeline visibility, and market conditions.

  3. Name your three priorities for next quarter. The three things that will have the biggest impact on hitting that revenue target. Write them on a card and put it where you will see it every day.
