You can write a solid business plan without a consultant by following a standard structure, answering each section with your own numbers and evidence, and getting one or two knowledgeable people to challenge it before you submit. You know your customers, costs and market better than anyone you could hire. What you need is a clear framework and the discipline to be honest with your figures.
Many owners put off their plan because it feels like a specialist job. Then a funder asks for one, a quote from a consultant comes back far bigger than expected, and the plan either gets rushed or written by someone who has never met your customers. Neither helps you.
Key takeaways
- Follow a standard structure and fill each section with your own numbers and evidence.
- Pick the format first: a one-page lean plan for your own use, or a full traditional plan for funders.
- Funders check viable financials, realistic forecasts and your ability to repay before they judge the writing.
- Avoid hockey-stick forecasts, leaving out your own salary and copying generic templates.
- Ask one or two knowledgeable people to challenge the plan before you submit it.
Why writing your own plan is usually better
A consultant can polish the words. They can’t know why your regulars choose you over the shop down the road, or which supplier always delivers late. Funders pick that up quickly when they ask follow-up questions.
There is also a practical reason. A plan you wrote yourself is a plan you can actually use. You will refer back to it, update it and measure yourself against it, instead of leaving it in a drawer. That is the difference between a document and a working plan, which we cover in more depth in our guide to business planning for SMEs.
A consultant still has a place, for example on a complex equity raise or a regulated industry. But for most small businesses applying for a loan, a supplier contract or an enterprise development programme, you can do it yourself.
Choose the right format first
Not every plan needs to be 40 pages. The US Small Business Administration describes two common formats: a traditional plan, which is detailed and can be dozens of pages long, and a lean startup plan, which is typically only one page and can take as little as an hour to make.
| Format | Best for | Length |
|---|---|---|
| Traditional plan | Bank loans, development finance, formal funding applications | Detailed, many pages |
| Lean or one-page plan | Testing an idea, internal direction, a simple business | Usually one page |
If a funder is involved, assume they want the traditional format. If it is for you and your team, start lean and add detail as you need it.
The sections to include (and what to put in each)
The SBA lists the core sections of a traditional plan. Here is what each one should answer, in plain terms.
- Executive summary. What the business does, who it serves, how it makes money and what you are asking for. Write this last.
- Company description. Your legal structure, CIPC registration, location, and the problem you solve.
- Market analysis. Who your customers are, how many of them there are in your area, and who else is serving them.
- Organisation and management. Who does what, including gaps you still need to fill.
- Products or services. What you sell, at what price, and why people buy it.
- Marketing and sales. How customers find you and how you turn interest into paid orders.
- Funding request. How much you need, what it will be spent on and how it will be repaid.
- Financial projections. Income, costs and cash flow for at least the next 12 months, with your assumptions written out.
- Appendix. Supporting documents: quotes, contracts, CVs, bank statements.
If you want a ready-made structure with prompts for each section, start with our business plan template for South Africa, which also shows what local funders tend to check.
A step-by-step way to write it yourself
Step 1: Gather your facts before you write
Pull together your last 6 to 12 months of bank statements, sales records, supplier quotes, price list and company documents. Writing is much faster when the numbers are in front of you.
Step 2: Draft the easy sections first
Start with the company description, products and team. These are things you already know. Getting words on the page builds momentum.
Step 3: Do real market research, not guesswork
Talk to ten customers. Visit or look up three competitors and note their prices. A Soweto spaza shop owner planning a second outlet, for instance, could count foot traffic at the new site for a week. That beats any generic industry report.
Step 4: Build the numbers from the bottom up
Estimate sales as units times price, month by month. List every cost, including your own salary. Then map when cash actually comes in and goes out, because a profitable plan can still run out of money if clients pay slowly. We explain why in why revenue grows while the bank balance doesn’t.
Step 5: Write the executive summary last
Once everything else is done, summarise it in one page. If you can’t, the plan isn’t clear yet.
Step 6: Get it challenged
Ask your accountant, a mentor or a business owner in a similar industry to read it and ask hard questions. You are not looking for praise. You are looking for the questions a funder will ask.
What funders actually look for
A beautifully written plan won’t save weak numbers. Finfind, which helps South African small businesses find finance, sums up what banks look for: financial statements that show a viable business, forecasts that are realistic and in line with the industry, and evidence that the business can afford to repay.
Finfind also points out that many applications fail not because the business is bad, but because the owner can’t provide the information the lender asks for. Having your bank statements, financials, cash flow forecast and company documents ready is half the battle.
Development funders care about the same basics. The Small Enterprise Development and Finance Agency (SEDFA), formed from the merger of sefa, Seda and the Cooperative Banks Development Agency, offers both finance and business development support, including a business needs assessment. For a wider list of programmes, see our overview of government funding options for small businesses.
Common mistakes when you go it alone
- Hockey-stick sales forecasts. Sales that triple in year two with no clear reason will be questioned. Show how each increase happens.
- Leaving out your own salary. If the plan only works because you work for free, it doesn’t work.
- Copying generic templates word for word. Funders read hundreds of plans. Borrowed phrases stand out.
- No link between the plan and the funding ask. Every rand requested should connect to a specific item in the plan.
- Treating it as finished. A plan is a working document. Review it at least every quarter.
Do you need software to write a business plan?
You can write a plan in a word processor and a spreadsheet. Software helps when it saves you from building financial formulas from scratch and keeps your plan connected to what actually happens afterwards. Our honest look at what business plan software should do covers what is worth paying for and what isn’t.
How B.E.T helps you write a plan without a consultant
B.E.T starts with a diagnostic of your business, so your plan is built on where you actually are, not a blank page. The plan builder walks you through each section with prompts, and the templates give you a structure funders recognise.
Once the plan is written, B.E.T turns it into tasks you can assign and track, with dashboards to see progress. That means the plan keeps working after the funding application is submitted. You can try the B.E.T plan builder free and see how far you get in an afternoon.
Frequently asked questions
Can I write my own business plan for a bank loan?
Yes. Banks care about realistic numbers, repayment ability and complete documents, not who typed the plan. If your figures are honest and your supporting documents are ready, a self-written plan is perfectly acceptable. Ask your accountant to check the financials before you submit.
How long does it take to write a business plan yourself?
A one-page lean plan can be done in an hour or two. A full traditional plan for a funding application usually takes a few days to a few weeks, mostly because gathering accurate numbers and market information takes time. Working in short daily blocks helps.
What is the most important part of a business plan?
For funders, the financial projections and the funding request carry the most weight, because they show whether the money can be repaid. For you as the owner, the market and sales sections matter just as much, because they show whether customers will actually buy.
Is a business plan template enough?
A template gives you structure, but the value comes from the thinking you put into each section. Use a template to make sure you cover everything, then fill it with your own evidence and numbers rather than generic wording.
Should I still pay someone to review my plan?
A review is much cheaper than a full write-up and often more useful. An accountant can check your financials, and a mentor or experienced owner can test your assumptions. Development agencies such as SEDFA also offer business development support worth asking about.
Your plan, in your words
You don’t need a consultant to write a plan that funders take seriously. You need a clear structure, honest numbers and someone to challenge your thinking.
