How to Write a Strong Business Case for a Small Business Grant

Writing a business case for a grant can feel daunting, but it's really just telling a compelling story backed by facts. Grant funders have heard hundreds of applications. Your job is to make yours stand out by being honest, clear, and specific about what you need and why.

What is a business case, anyway?

A business case is essentially a document that answers one question: Why should someone give you money?

It's not a formal, scary thing. It's proof that you've thought things through. It shows funders that their money will be used sensibly and will actually make a difference to your business.

The five things every business case needs

1. A clear problem you're trying to solve

Start by explaining what's holding your business back right now. This isn't about being negative — it's about being honest.

• Are you losing customers because you can't take online payments?
• Do you need a skilled employee but can't afford to train someone?
• Is your equipment so old it's costing you in lost productivity?

Be specific. Don't just say "I need to grow." Say "I'm losing about £500 a month in orders because customers can't find me online."

2. Your solution (and why it's the right one)

Explain exactly what you're going to do with the grant money. This should be specific enough that someone unfamiliar with your business could understand it.

For example:

• Vague: "I want to invest in marketing."
• Strong: "I'll invest £3,000 in a new website and Google Ads to reach customers in my local area. This is the right approach because 70% of my customers search for my services online."

If you've considered other options, mention them briefly and explain why you chose this one instead. This shows you've done your homework.

3. A realistic budget breakdown

Funders hate surprises. Tell them exactly where the money goes.

Create a simple table or list:

• New laptop: £800
• Accounting software (annual): £240
• Training course: £500
• Contingency (10%): £154
• Total: £1,694

Include a contingency fund of about 10% for unexpected costs. It shows you're thinking realistically.

Don't inflate costs to ask for more money. Funders can spot this, and it damages your credibility.

4. How you'll measure success

This is where many applicants fall short. Funders want to know what "better" looks like for your business.

For example:

• Current situation: 30 customers per month
• After the grant: 45 customers per month within 6 months
• How you'll measure it: Your customer database and monthly sales records

Make your targets achievable. Growth should be realistic based on your industry and market.

5. Evidence you can actually deliver

This is your credibility section. Show that you've successfully run a business before, or that you have the skills to do this.

Include:

• How long you've been trading
• Your relevant experience or qualifications
• Any previous projects you've completed successfully
• Customer testimonials or case studies (if you have them)
• Your team's skills and experience

If you're brand new, that's fine — but mention any training you've done, mentoring relationships, or advisory support you've got in place.

How to structure your business case

1. Executive summary (1 page max): A one-page overview of the whole thing. Write this last.
2. The problem: What's the issue? What does it cost you?
3. Your solution: What will you do? Why is this the right approach?
4. Budget: Itemised spending breakdown.
5. Impact: How will things improve? What are your targets?
6. About you: Why are you the right person to make this happen?
7. Timeline: When will you spend the money? When will you see results?

Writing tips that actually work

Use plain language. Write how you'd explain your business to a friend, not how a corporate document sounds. Avoid jargon. If you must use technical terms, explain them.

Be honest about risks. Every business has challenges. Acknowledge them and explain how you'll handle them. This builds trust.

Keep it focused. Don't try to solve every problem at once. One clear, well-defined project is stronger than five vague ones.

Proofread. Spelling mistakes and poor grammar make you look unprofessional. Ask a friend to read it before you submit.

Follow the funder's guidelines exactly. If they ask for 2 pages, don't send 5. If they want a specific format, use it. This shows you can follow instructions.

Common mistakes to avoid

• Being too vague: "I need funding to grow my business" tells them nothing.
• Unrealistic numbers: Don't promise to triple your revenue in three months. Funders see through this.
• Asking for more than you need: It's tempting, but it wastes money and damages your reputation.
• Forgetting about risk: Every project has risks. Show you've thought about them.
• Making it too long: Grant assessors read hundreds of applications. Respect their time.

Final thoughts

Writing a strong business case takes time — probably 4 to 6 weeks if you're doing it properly. You'll need to gather financial information, think through your strategy, and get feedback. That's normal.

The good news is that this document is useful beyond just grant applications. It helps you clarify your own thinking about what your business needs. That's valuable in itself.

Remember: funders want to say yes. They have money to distribute. Your job is to make it easy for them to say yes to you by being clear, honest, and realistic about what you need and why.
