It’s easy to focus on sales, product, or funding when you’re running a startup — but without a financial model, you’re flying blind.

Whether you’re preparing for investor conversations, applying for a loan, or just trying to figure out how much you can spend on hiring, your budget and forecast are the roadmap that tells you where you’re headed — and what could get in your way.

At Fractional Accounting, we help startups across Montreal and Quebec build their first financial models. Here’s how to get started with a practical, no-fluff approach — even if you don’t have a finance background.

What’s the Difference Between a Budget and a Forecast?

• Budget = what you plan to spend and earn over a set period (usually 12 months).
• Forecast = a projection based on what’s already happening in the business — it changes over time.

You build a budget once a year (ideally before the fiscal year starts), and you update your forecast monthly or quarterly to reflect real results.

Think of your budget like Google Maps setting your route — and your forecast like Waze updating you on traffic.

Why Budgeting Matters for Startups

Startups operate in uncertain environments. Budgets give you guardrails. Forecasts give you warning signs. Together, they help you:

• Track your burn rate and runway
• Plan hires and major purchases
• Prepare for seasonality or slow periods
• Set revenue goals and monitor performance
• Communicate clearly with investors or banks

Without these tools, you’re likely making decisions emotionally — or reactively — instead of strategically.

Step-by-Step: Build Your First Startup Budget

1. Start with Revenue

List your income sources. Project sales month by month based on realistic assumptions — not wishful thinking. Be conservative on growth unless you have strong proof.

2. Map Out Your Expenses

Break these into categories like:

• Payroll (including yourself)
• Software & subscriptions
• Marketing & advertising
• Professional services (legal, accounting, etc.)
• Office or coworking space
• Cost of goods sold (COGS), if applicable

3. Add in One-Time Costs

Think: website builds, product development, branding, equipment, etc.

4. Build a Simple Spreadsheet

You don’t need complex tools. Start with a 12-month Excel or Google Sheet layout with rows for each revenue and expense line, and columns for each month. Include a column for “actuals” and one for “variance.”

5. Estimate Cash Flow

Include expected cash inflows and outflows. Make sure to include taxes, loan repayments, and delayed customer payments.

Forecasting: Keeping the Budget Alive

Your forecast is a living document. Every month or quarter, compare actual results to your budget. Adjust your projections based on:

• New hires or departures
• Delayed revenue
• Unexpected expenses
• Market conditions

Doing this regularly helps you course-correct early instead of dealing with a cash crunch later.

What Investors and Lenders Want to See

If you're fundraising or applying for a BDC loan, they’ll want:

• 12-month budget (minimum)
• 2–3 year forecast (ideally)
• Assumptions clearly stated (e.g., CAC, revenue growth %)
• Cash flow visibility
• Sensitivity analysis (what happens if revenue drops 20%?)

Pro tip: It’s not about perfect accuracy. It’s about showing that you understand your business and your risks.

When to Get Help

Don’t wait until a lender or investor asks for a financial model — by then, you’re already behind.

If you’re not sure how to start or want help building a model that actually aligns with your operations, working with a fractional controller can save you time, stress, and missed opportunities.
