- A CFO’s job is to turn numbers into decisions and protect the cash, not to keep the books. That is the controller’s or accountant’s work.
- The core remit is seven things: FP&A, cash and runway, fundraising, the board pack, capital allocation, pricing and unit economics, and controls and compliance oversight.
- A CFO’s week is cash and decisions; the month is reporting and planning; a raise takes over the calendar for months at a time.
- The role changes by stage: at seed it is part-time runway watching, by Series B it is a full strategic function with a team.
- A CFO owns outcomes, not data entry. The most expensive mistake is hiring one to do bookkeeping.
| 7 Core areas a startup CFO owns, from FP&A to controls | The future The CFO’s time horizon: a controller owns the present, an accountant the past | 0% Of a good CFO’s day that should be spent on data entry or bookkeeping |
To keep this concrete we follow one company: Brewly, a D2C coffee brand growing from ₹3 crore to ₹60 crore in revenue, seed to Series B, and from 8 to 80 people. We use Brewly to show what its CFO actually does at each point along the way.
The One Job Behind the Title
If you strip away the org chart, what a CFO does comes down to one sentence: turn the numbers into good decisions, and make sure the company never runs out of cash at the wrong moment. Everything else, the model, the board pack, the raise, the controls, is in service of that.
This is why the CFO is a forward-looking role. An accountant tells you what happened last month. A controller tells you the books are right and the filings are done. A CFO tells you what is likely to happen next, what it means for cash and value, and what you should do about it. The CFO is the person in the room who can say “if we keep hiring at this pace, we run out of money in February, and here are the three levers that change that.”
For Brewly at seed, the founder was effectively acting as a part-time CFO: watching the bank balance, deciding what to spend on, and worrying about runway. The job existed long before the company could afford to fill it. That is normal. The question is never “do we have a CFO?” but “who is doing the CFO’s job, and are they doing it well enough?”
The CFO role is the work, not the title. Plenty of seed-stage founders do the CFO’s job themselves, or split it between a controller and a fractional CFO. You only need a full-time CFO when the work is too big for that arrangement, which we cover in our pillar guide on hiring a CFO.
The Seven Things a Startup CFO Owns
Drill into the role and the CFO responsibilities in a startup cluster into seven areas. The CFO owns the outcome of each, even when other people do the underlying work.
1. Financial planning and analysis (FP&A)
The CFO owns the financial model and the operating plan: the budget, the forecast, and the monthly comparison of plan versus actual. This is where the company decides how many people to hire, how much to spend on marketing, and what the next twelve months should look like in numbers. For Brewly, FP&A is what turned “let us grow fast” into a concrete ₹15 crore revenue target with a matching hiring and spend plan.
2. Cash flow and runway management
This is the part that keeps founders up at night, and it is squarely the CFO’s job. How much cash do we have, how fast are we burning it, how many months of runway remain, and what changes that? A CFO maintains a rolling cash forecast, manages working capital (collections, payables, inventory for a D2C brand like Brewly), and flags problems months before they bite.
3. Fundraising and investor relations
When a startup raises, the CFO owns the financial machinery of the deal: the model, the data room, the cap table and dilution math, term-sheet review, and the financial parts of due diligence. The founder leads the story; the CFO makes the numbers defensible. In India this also means handling CCPS, FEMA share-transfer rules, and valuation-related compliance so the round actually closes.
4. The board reporting pack
Every board meeting needs a credible pack: actuals versus plan, key metrics, cash and runway, and a clear narrative. The CFO builds and owns this, and increasingly fields the hard questions in the room. A clean, honest board pack is one of the biggest things that makes the next raise easier.
5. Capital allocation
Money is finite, so someone has to decide where it goes: which team gets the next ten hires, whether to spend on a new product line or double down on the proven one, build versus buy. The CFO brings the numbers and the discipline to those choices so they are made on evidence, not the loudest voice in the room.
6. Pricing and unit economics
A CFO protects the economics of the business: gross margin, contribution margin, customer acquisition cost versus lifetime value, and the price itself. For Brewly, this meant making sure that every ₹500 bag of coffee actually made money after discounts, shipping and returns, not just on paper.
7. Financial controls and compliance oversight
The CFO does not do the GST or TDS filing, but they own the system that ensures it happens correctly and on time, along with approval limits, segregation of duties, and the controls that prevent leakage and fraud. They make sure the company is clean for MCA, the tax authorities, and any future buyer or investor.
A simple way to remember the remit: a CFO answers three questions over and over. Where is the cash going? What is the plan worth? How do we fund and protect it? If a task does not serve one of those three, it is probably not the CFO’s job.
What a CFO Actually Does in a Typical Week and Month
The seven areas above sound abstract, so here is what they look like on a calendar. The CFO role has a clear rhythm: the week is about cash and decisions, the month is about reporting and planning, and a fundraise overrides everything for a few months.
| Cadence | What the CFO does |
|---|---|
| Every week | Review cash position and the rolling cash forecast, check collections and large payments, approve key spends, answer ad-hoc pricing and hiring questions |
| Every month | Sign off the management reporting pack (MIS) once the close is done, review runway and budget versus actual, update the forecast, prepare investor and team updates |
| Every quarter | Build the board pack and present it, re-plan for the rest of the year, review unit economics and capital allocation, check compliance status |
| During a raise | Own the model and data room, run financial due diligence, review the term sheet and SSA / SHA numbers, manage the cap table and dilution, close the round |
Notice what is missing from this list: no voucher entry, no reconciling individual bank lines, no preparing the GST return by hand. The CFO oversees that those are done, but their own hours go to cash, planning, the board and the raise.
When Brewly’s fractional CFO joined at Series A for a few days a month, the time went almost entirely into the model, the board pack and the raise. The day-to-day close and filings stayed with the controller. That split is exactly right: the CFO’s scarce hours buy judgement, not throughput.
What a CFO Does NOT Do
Knowing what the role excludes is just as useful as knowing what it includes, because most expensive hiring mistakes come from confusing the two. A CFO does not:
- Bookkeeping and data entry. Recording invoices, vouchers and bank transactions belongs to an accountant.
- Routine statutory filing. Preparing and filing GST returns, TDS, and MCA forms is the accountant’s and controller’s work; the CFO oversees that it happens.
- The month-end close itself. A controller runs the close. The CFO reviews the output and uses it to plan.
- Payroll processing. Running payroll is operational; the CFO sets policy and watches the cost.
- Being a one-person finance department. A CFO with no execution layer beneath them cannot deliver, because their time and seniority are wasted on tasks a junior can do.
The classic mistake is hiring a senior CFO and then handing them the bookkeeping because “they are good with numbers.” You end up paying CFO money for accountant work, the strategic job goes undone, and the CFO leaves. If your real need is clean books and timely filings, hire a controller or accountant first, not a CFO.
CFO vs Financial Controller vs Accountant
This is the comparison founders most often get wrong, so it is worth being precise. All three roles touch the numbers, but they own different things and look at different time horizons.
| Role | Owns | Time horizon |
|---|---|---|
| Accountant / Bookkeeper | Recording transactions, vouchers, GST and TDS filing support | The past |
| Financial Controller | Accuracy, compliance, payroll, month-end close, MIS production | The present |
| CFO | Planning, fundraising, board, capital allocation, controls, strategy | The future |
The simplest way to see it: the accountant and controller make sure the numbers are right; the CFO decides what to do with them. A controller produces the MIS; the CFO reads it, spots that gross margin slipped two points, and changes pricing. Most startups should hire from the bottom up: a reliable accountant, then a controller, then CFO-level help on top, often fractional before full-time.
Past, present, future. The accountant owns the past, the controller owns the present, the CFO owns the future. If the question starts with “what should we do,” it is a CFO question.
How the CFO Role Changes from Seed to Series B
The CFO’s job is not fixed; it grows with the company. The same seven areas exist at every stage, but the depth, the tools and who does the work all change. Here is how it plays out for Brewly.
| Seed | Series A | Series B | |
|---|---|---|---|
| Revenue / team | ~₹3 cr / 8 people | ~₹15 cr / ~30 people | ~₹60 cr / ~80 people |
| Who does the CFO job | Founder + outsourced accountant | Controller + fractional CFO | Full-time CFO + team |
| Main CFO focus | Watch runway, keep books clean, basic MIS | Build the model, run the raise, set up the board pack | Full FP&A, controls, capital allocation, team building |
| Hardest question | How long does our cash last? | Are our unit economics fundable? | Where do we deploy capital for the best return? |
The pattern is consistent: at seed the CFO job is mostly defence (do not run out of cash), by Series A it shifts to fundraising and planning, and by Series B it becomes a full strategic function with a team underneath. The seniority you need rises with the complexity of the question you are trying to answer.
What Good Looks Like: Signs the CFO Job Is Being Done Well
Whether the role is filled by a founder, a fractional CFO or a full-time hire, you can tell if the CFO job is being done well by a few simple signs.
| You always know your runway |
At any moment, someone can tell you how many months of cash you have and what would change it. If that answer is fuzzy, the CFO job is not being done.
| The board pack is calm and credible |
The numbers are ready on time, they reconcile, and they tell a consistent story quarter after quarter. Investors trust them, which makes the next raise easier and faster.
| Decisions get the numbers they deserve |
Pricing changes, big hires and new bets are made with a clear view of the economics, not on gut feel. That is the CFO turning numbers into decisions, which is the whole point of the role.
“A CFO is not the person who keeps the books. A CFO is the person who reads the books and decides what the company should do next. If your CFO is doing data entry, you have hired the wrong role for the wrong job.”
Ankit Sarawagi, CFOmatrixFrequently Asked Questions
What does a CFO do in a startup?
A startup CFO owns the forward-looking side of finance: financial planning and analysis (FP&A), cash-flow and runway management, fundraising and investor relations, the board reporting pack, capital allocation, pricing and unit economics, and oversight of financial controls and compliance. In short, the CFO turns numbers into decisions and makes sure the company does not run out of cash. This is different from an accountant or controller, who own the accuracy and timeliness of the numbers themselves.
What are the main responsibilities of a CFO?
The core responsibilities of a startup CFO are: building and owning the financial model and plan (FP&A), managing cash and runway, leading fundraising and investor relations, producing the board reporting pack, allocating capital across teams and bets, setting pricing and protecting unit economics, and overseeing financial controls and compliance such as GST, TDS and MCA filings. The CFO owns these outcomes even when other people do the underlying work.
What does a CFO NOT do?
A CFO does not do day-to-day bookkeeping, data entry, voucher-level accounting or routine statutory filing. Those belong to an accountant or financial controller. A CFO oversees that this work is accurate and on time, but their own job is planning, fundraising, capital allocation and board confidence. Hiring an expensive CFO to do bookkeeping is the most common and costly mismatch founders make.
What is the difference between a CFO and a financial controller?
A financial controller owns the accuracy of the numbers: bookkeeping, accounting, statutory compliance, payroll and the month-end close. A CFO owns what you do with the numbers: planning, fundraising, capital allocation, board and investor communication, and strategic decisions. The controller looks at the present and recent past; the CFO looks at the future. Many startups hire a controller first and add a fractional CFO on top.
What does a CFO do in a typical week or month?
In a typical week a startup CFO reviews cash and the rolling cash forecast, checks collections and large payments, and answers ad-hoc questions on pricing or hiring. The monthly rhythm adds the management reporting pack (MIS), a runway and budget-versus-actual review, and board or investor updates. Around a raise, fundraising work, the data room and the model dominate the calendar for several months.
Does a startup CFO own fundraising?
Yes, the CFO usually owns the financial side of fundraising: the model, the data room, the cap table and dilution math, term-sheet review and the financial parts of due diligence. The founder still leads the story and the investor relationships, but the CFO makes the numbers defensible and keeps the process organised. In India this also means handling CCPS, FEMA and valuation-related compliance.
When does a startup need a full-time CFO versus a fractional one?
Most Indian startups do not need a full-time CFO until finance becomes a daily strategic function, usually around or after Series B. Before that, the CFO responsibilities can be covered by a fractional or virtual CFO working a few days a month on top of a controller or accountant. The trigger to go full-time is an event such as a complex raise, a multi-entity or cross-border structure, or a board that needs constant financial leadership.
