Start with the decision, not the document

Most small business owners write a plan because someone asks for one — a bank manager, an investor, a grant panel. That is a perfectly good reason to start, but it is a poor reason to finish. A plan that exists only to satisfy a lender will sit in a drawer and gather dust within a fortnight.

The plans that actually help a business grow are the ones built around decisions. Should you hire a second engineer or lease more space? Can you afford to drop your biggest client and chase better-paying work? Is the new product line going to pay for itself inside eighteen months? Write the plan to answer questions like these, and it will do double duty: it will give you clarity, and it will give a funder confidence.

Aim for something between eight and twenty pages. Long enough to cover the numbers properly, short enough that a busy reader gets through it on a train journey.

The executive summary earns the rest of the read

Write this section last, but put it first. Assume it is the only page that gets read properly — often it is.

In a single page, cover:

• What the business does and who it sells to, in plain language. No jargon about "solutions ecosystems".
• What you are asking for, precisely — £75,000 over three years, or a £40,000 equipment lease, or nothing at all if the plan is purely internal.
• What the money does. "Two new vans and a part-time installer, which takes us from 60 to 95 installations a year."
• The headline numbers: current turnover, projected turnover in year three, and the margin you expect to hold.
• Why you. Two or three sentences on the experience that makes this credible.

If a reader finishes your summary and cannot say what you want and why it will work, rewrite it before touching anything else.

Show that you understand your market, not just your product

Lenders see hundreds of plans claiming a growing market. Very few show evidence. Yours should.

Be specific about your customer. "SMEs in the Midlands" is not a customer segment; "independent dental practices with two to four chairs, buying sterilisation consumables monthly" is. Once you have that level of detail, the rest follows — where they are, what they currently buy, what they pay, and why they would switch to you.

Then deal honestly with competition. Every business has competitors, even if they are the incumbent supplier, a DIY approach, or simply doing nothing. Name the two or three that matter and say what you do better or cheaper. A plan that claims no competition reads as either naive or dishonest, and both lose funding.

Include the numbers you actually know: your customer count, average order value, retention rate, and where new enquiries came from last year. Real figures from your own trading history are worth more than any industry report.

Operations, people and the unglamorous detail

This is the section most owners rush, and it is where lenders find the holes. They want to know the business can physically deliver what the forecast promises.

• Capacity: how many jobs, units or clients can you handle per month with current staff and equipment? What breaks first when demand rises?
• Key people: who does what, and what happens if one of them is off for six weeks? If the business depends entirely on you, say so and explain your plan to reduce that.
• Suppliers: who your main ones are, lead times, and whether you have a backup. Recent disruption has made this a genuine concern for funders.
• Compliance: the licences, insurance, accreditations and health and safety obligations that apply to your trade, and confirmation that they are current.
• Systems: your accounting software, CRM and any processes that keep quality consistent as you grow.

Be candid about weaknesses here. A plan that acknowledges a single-supplier risk and explains the mitigation is far more convincing than one that pretends no risk exists.

The numbers a lender actually reads

You need three statements: profit and loss, cash flow, and balance sheet. The cash flow forecast is the one that decides most applications, because businesses rarely fail from lack of profit — they fail from running out of cash on a Tuesday.

Prepare monthly cash flow for the first twelve months, then quarterly to year three. Show money coming in as it actually arrives, allowing for your payment terms and the reality that customers pay late. Show VAT, PAYE and Corporation Tax as separate lines with realistic timing. Include your own drawings.

Add a break-even calculation: how much you must sell each month before you cover fixed costs. Then run a downside version. What happens if sales come in 20 per cent below plan — do you still service the loan? Funders almost always ask this, and having the answer ready marks you out as someone who thinks clearly.

State every assumption behind the figures. "Ten new clients a month at an average of £420" invites scrutiny, and that is exactly what you want.

Treat it as a working document

Review your plan quarterly against actual results. Note where you were wrong and why. That discipline is what separates a plan that helped a business grow from a document written once for a meeting. It also means that when you go back to your bank or an investor in two years, you have a track record of forecasting honestly — which is the single most valuable thing you can bring to that conversation.
