Summary
A fractional CFO is an experienced chief financial officer who works with your company part-time, typically a few days a month, for a fraction of a full-time salary. For Ottawa founders juggling IRAP projects, SR&ED claims, government contracts and fundraising, a fractional CFO turns bookkeeping into forecasts, cash plans and investor-ready reporting. This guide explains what they do, how they differ from bookkeepers and accountants, when you need one and what it costs, with a quick self-check tool and notes on CRA business number (BN) setup.
Most founders don't start a company to manage finance. In Ottawa, many of them are engineers from Kanata North, researchers spinning technology out of a university lab, or consultants who turned government work into a product company. They know their product and their customers. What they often don't have is someone who can tell them, with confidence, how many months of cash they have left, whether they can afford the next three hires, or what investors will think of their numbers.
That is the gap a fractional CFO fills. The term sounds like jargon, but the idea is simple: you get a senior finance leader's experience for the part of the week you actually need, without paying for a full-time executive you're not ready for.
This guide explains the role in plain English. If you already know you need help, Ledgerive's fractional CFO services work with founders across Ottawa, Kanata and the rest of Ontario.

1. What Is a Fractional CFO?
A fractional CFO is a chief financial officer you share. Instead of one company paying a full-time salary, several companies each buy a "fraction" of an experienced CFO's time, often one to four days a month. They join your leadership meetings, own your financial plan, and speak for your numbers with investors, lenders and your board, just with fewer hours.
- Fractional means part-time and ongoing, not a one-off project.
- Senior means strategic: they help decide what to do, not just record what happened.
- Flexible means you can scale hours up for a fundraise and back down afterwards.
2. Bookkeeper, Accountant, Controller or CFO?
Founders often mix these roles up. Here's a simple way to tell them apart:
| Role | Main question they answer | Typical work |
|---|---|---|
| Bookkeeper | "What happened?" | Records transactions, reconciles accounts, runs payroll |
| Accountant (CPA) | "Is it reported correctly?" | Year-end financial statements, corporate tax, HST filings |
| Controller | "Are the numbers reliable every month?" | Monthly close, internal controls, management reports |
| CFO | "What should we do next?" | Forecasts, cash strategy, fundraising, pricing, board and investor relations |
A simple analogy: the bookkeeper keeps the logbook, the accountant files the official records, and the CFO plans the route. You need all three eventually, but the CFO only adds value once the logbook is accurate. If your books are behind, start with bookkeeping services.
3. What a Fractional CFO Actually Does
- Cash flow forecasting: a rolling 13-week and 12-month view of cash so you know your runway.
- Budgets and financial models: plans for revenue, hiring and spending, built with our financial modeling services approach.
- Fundraising: investor-ready model, data room, valuation support and term sheet review.
- Bank and government funding: loan applications, IRAP and other program reporting, and supporting SR&ED claims.
- Unit economics and pricing: gross margin, customer acquisition cost and payback, contract pricing.
- Board and investor reporting: a monthly or quarterly pack with KPIs and commentary.
- Team oversight: managing the bookkeeper and external accountant and improving systems.
Three common myths
- "We're too small for a CFO." You may be too small for a full-time CFO, but a few hours a month can prevent expensive mistakes on cash, pricing and funding.
- "Our accountant already does this." Most accountants focus on year-end statements and tax. Few build rolling forecasts or sit in on monthly leadership decisions.
- "A fractional CFO is just a consultant." Consultants usually deliver a project and leave. A fractional CFO stays involved month after month and is accountable for the plan.
4. Why Ottawa Founders Use Fractional CFOs
Ottawa's mix of deep tech, government and public-sector work creates finance needs that many other cities don't have:
| Situation | How a fractional CFO helps |
|---|---|
| NRC IRAP projects | Budgets eligible costs, tracks spending and prepares claims and reports |
| SR&ED tax credits | Tracks R&D labour and costs through the year and plans cash around refund timing |
| Government contracts | Prices bids, models long payment cycles and manages working capital |
| Seed and Series A rounds | Builds the model, runway plan and data room investors expect |
| Competing for tech talent | Models hiring plans, salaries and equity so growth stays funded |
Many Ottawa companies also sell to US customers or government buyers, which adds foreign exchange, longer payment terms and procurement rules to the mix. The point isn't the credits or contracts themselves; it's that each one adds deadlines, reporting and cash timing that a busy founder can easily get wrong.
5. What It Costs
| Level | Hours per month | Monthly fee | Best for |
|---|---|---|---|
| Advisory | 8–12 | $3,000 – $4,500 | Early-stage founders who need a monthly finance check-in |
| Core | 16–24 | $5,000 – $7,500 | Growing companies with forecasts, board reporting and funding needs |
| Strategic | 30–40 | $8,000 – $10,000+ | Companies raising capital or managing complex growth |

| Days 61–90 | Run the rhythm | First monthly finance review, board pack and funding plan |
8. BN Registration and the Finance Basics
One of the first things a fractional CFO checks is your CRA setup, because problems here show up in every funding application and due diligence.
- CRA business number: your nine-digit business number is the anchor for every CRA program account. A corporation receives one at incorporation.
- BN registration for program accounts: add GST/HST (RT) once taxable sales pass $30,000 in four consecutive calendar quarters, and payroll (RP) before paying your first employee.
- Corporate structure: SR&ED's enhanced refundable credits are generally available to Canadian-controlled private corporations, and IRAP generally works with incorporated businesses, so structure matters early.
- Filings in good standing: late HST, payroll or corporate returns can delay SR&ED refunds and worry investors.
- Records: keep your CRA business number details, incorporation documents and cap table in one place for the data room.
9. How to Choose a Fractional CFO
- Relevant experience: have they worked with companies at your stage and in your sector?
- Fundraising track record: can they describe rounds or loans they helped close?
- Accounting backing: do they work with CPAs who understand Canadian tax, SR&ED and HST?
- Clear scope: is it clear what's included each month, and what costs extra?
- Communication: will they explain numbers in plain English to you and your team?

10. Frequently Asked Questions
What does a fractional CFO do?
A fractional CFO is an experienced chief financial officer who works with your company part-time, usually for a set number of hours or days each month. They build budgets and forecasts, manage cash flow, prepare board and investor reporting, support fundraising and bank financing, improve pricing and margins, and oversee the bookkeeping and accounting team.
How much does a fractional CFO cost in Canada?
Fees vary by scope and experience. Many Canadian fractional CFO engagements fall roughly between $3,000 and $10,000 or more per month, depending on hours and complexity, compared with total compensation that can exceed $250,000 a year for a full-time CFO. Some firms also offer project pricing for fundraising or due diligence.
What is the difference between a fractional CFO and a bookkeeper?
A bookkeeper records transactions and keeps the books accurate. An accountant prepares financial statements and tax filings. A fractional CFO uses those numbers to plan ahead, building forecasts, managing cash, advising on pricing, hiring and funding, and representing the company with investors, lenders and the board.
When should a startup hire a fractional CFO?
Common triggers include preparing to raise a seed or Series A round, applying for significant bank or government funding, revenue of roughly $1 million to $20 million, rapid hiring, cash flow surprises, a board that wants better reporting, or a founder spending too much time on finance instead of the business.
Is a fractional CFO worth it for a small business?
It often is when the business is large enough that financial decisions carry real risk but too small to justify a full-time CFO. The value comes from better cash management, funding outcomes, pricing and decisions. Very early businesses usually benefit more from solid bookkeeping first.
Summary
A fractional CFO gives Ottawa founders senior finance leadership for a few days a month: cash forecasts, budgets, fundraising and funding support, and clear investor reporting, at a fraction of a full-time salary. Start with accurate books, check that BN registration and your CRA business number accounts are in order, and bring in a fractional CFO when funding, growth or complexity makes financial decisions too important to leave to guesswork.
