A business plan is a decision-making document. It explains the customer problem, the proposed offer, how the business will operate, the resources required and the assumptions that still need testing. Its depth should match the audience: an internal operating plan is different from a submission to a lender or investor.
A useful plan does not predict the future with certainty. It makes choices, numbers, risks and evidence visible so they can be challenged and improved.
Separate strategy from the written plan
Strategy is the set of choices about where the business will compete, whom it will serve, how it intends to create value and what it will not pursue. The business plan records those choices and connects them to market evidence, operations, people, milestones and finances.
If the underlying choices are unclear, more pages will not fix the problem. Start by defining the decision the plan must support.
Identify the reader and purpose
An owner may need a concise operating plan for the next 12 months. A management team may need responsibilities, dependencies and measures. A lender or investor may request a more formal package, supporting documents and a specific financial format.
Ask the intended reader what they require rather than relying on a generic minimum length or age for the business. Financing criteria differ by institution, program, sector and risk. Legal, accounting and financing advice should come from appropriately qualified professionals.
Answer the core business questions
- Customer: Who has the problem, what triggers action and what evidence shows demand?
- Offer: What is being sold, what is included and why might a suitable customer choose it?
- Market: What alternatives exist, how is the market changing and which assumptions are uncertain?
- Economics: How does the business earn revenue, what drives margin and cash, and what costs change with volume?
- Operations: How will the offer be sold, delivered, supported and improved?
- People: Which capabilities, responsibilities and external specialists are required?
- Risk: What could materially change the plan, and what early indicators would reveal it?
Build financial assumptions from operating drivers
Revenue projections should connect price, volume, timing and collection. Costs should distinguish fixed commitments from expenses that vary with activity. Include working-capital needs, tax considerations and the timing difference between a sale and cash receipt.
BDC’s guidance on financial projections recommends using research, building sales and expense forecasts, preparing cash-flow projections and testing scenarios. Forecasts remain estimates; document the assumptions and update them with actual results.
Turn the plan into milestones
Break the next period into decisions and evidence, not just activity. A milestone might be a defined number of qualified customer interviews, a tested delivery process, a supplier agreement, a target contribution margin or a financing decision.
Give each milestone an owner, deadline, measure and review rule. If a milestone is missed, identify whether the problem is the assumption, the execution, the resources or the timetable before changing direction.
Test downside and capacity
Create at least a base case and a downside case. Ask what happens if sales arrive later, conversion is lower, a key cost increases or the owner has less available time. Then examine the operational ceiling: staffing, delivery time, inventory, support and cash can constrain growth before demand does.
This is not pessimism. It helps the business decide which commitments are reversible and where a contingency is needed.
Review the plan as evidence changes
Choose a practical review cycle. Compare forecast with actual results, note why the variance occurred and update the next action. Preserve earlier assumptions so the team can learn instead of rewriting history.
BDC’s entrepreneur toolkit includes planning and financial resources for Canadian businesses. Templates can improve structure, but they do not replace market evidence, professional advice or judgment.
Frequently asked questions
How long should a business plan be?
There is no universal length. Use the shortest format that gives the intended reader enough evidence, operational detail and financial clarity to make the relevant decision.
Is a business plan only for a start-up or loan?
No. An established business can use one to evaluate an expansion, clarify priorities, prepare for financing or align a team. The content should match the decision.
How often should it be updated?
Update it when material evidence or assumptions change, and review operating measures on a regular cadence suited to the business. A plan that is never reviewed is unlikely to guide action.
