What a Virtual CFO Does for a Startup: The First 90 Days
What a virtual CFO does in a startup's first 90 days: a books health check, a close calendar, the first MIS, a cash forecast, payment controls and compliance.
Most founders who sign up a virtual CFO know what they want at the end: clean numbers, a runway they trust and investor reporting that goes out on time. What they rarely see in advance is the order in which that gets built. The first 90 days decide whether the engagement becomes a real finance function or stays a monthly report nobody reads.
This piece sets out what a virtual CFO should do in a startup in the first three months, what the founder has to hand over, and how to judge the engagement at day 90. If you are still deciding whether you need one at all, start with my note on why growth-stage startups need a virtual CFO.
Days 1 to 15: access, handover and a health check
The first job is to see everything. That means read access to the accounting system and bank accounts, the GST, TDS and income tax portals, the company's MCA filings, payroll, the payment gateway and the cap table. A virtual CFO who works only from exported spreadsheets will miss what matters.
The output of the first two weeks is a written health check: what is reconciled and what is not, which statutory filings are pending, where cash is leaking, and which numbers the founder has been quoting that do not match the books. It should rank issues by risk, not by how easy they are to fix.
- Bank and payment gateway balances reconciled to the books, month by month
- Input tax credit in the books matched to GSTR-2B, since credit that does not appear there is generally not available
- TDS deducted and deposited matched to Form 26AS and the AIS
- Share capital, allotments and ROC forms matched to the cap table
- Open notices from GST, income tax or the MCA listed with their reply dates
Days 15 to 45: fix the base before building reports
Reports built on unreconciled books are expensive fiction. So the next month goes into the base: a chart of accounts that separates revenue streams and cost centres the way the business is actually run, a clean vendor and customer master, and catch-up entries for anything the health check found missing.
This is also when the close calendar is set. A workable target for a young company is to close the books within the first 7 to 10 working days of the next month, with a named owner for each step: bank entries, sales and GST, payroll, accruals and prepaid expenses, and a final review. The target is a choice, not a rule, but without one the close drifts later every month.
Two India-specific items belong here. Payments to micro and small enterprise suppliers that stay unpaid beyond the MSMED Act time limit, at most 45 days, can lose their income tax deduction for the year under section 43B(h), so supplier ageing needs an MSME flag. And once the company is profitable, advance tax falls due in June, September, December and March; missing it means interest. The section number above follows the Income-tax Act, 1961; the Income-tax Act, 2025 applies from 1 April 2026 and renumbers it.
Days 45 to 75: the first MIS, budget and cash forecast
With a clean base, the first proper MIS can go out: profit and loss by segment, balance sheet, cash and runway, unit economics and a short list of leading indicators. It should arrive on a fixed day each month and carry a few lines of commentary on what changed and why.
Alongside it, the virtual CFO builds a budget for the rest of the financial year and a rolling 13-week cash forecast. The budget says what the company plans to spend; the forecast says whether the bank balance survives the plan. Founders need both, and the two should reconcile.
Days 75 to 90: controls, compliance and an operating rhythm
By the third month the focus shifts from fixing to running. Payments move to a maker-checker process with an approval matrix: who can raise a payment, who approves it, and above what amount the founder must sign off. The compliance calendar goes live, with every GST, TDS, payroll, ROC and FEMA date owned by a named person.
The rhythm is then agreed in writing: a weekly cash call, a monthly MIS review and a quarterly board or investor pack. If the company has foreign investors, the calendar also tracks FEMA reporting such as Form FC-GPR after each allotment and the annual FLA return.
What the founder has to give
A virtual CFO cannot build a finance function around a founder who is never available. Expect to give about an hour a week in the first month, share bank and portal access promptly, and name one internal person, even a junior accountant, who owns daily entries. The virtual CFO designs, supervises and reviews; someone inside still has to record.
One structural point is easy to miss. Under section 144 of the Companies Act, 2013, a company's statutory auditor cannot provide it with accounting, bookkeeping or management services. Your virtual CFO and your statutory auditor should therefore be different firms, and the auditor will then test what the virtual CFO has built.
How to judge the engagement at day 90
Judge it by outputs, not effort. At day 90 you should have reconciled books, a close that finishes on schedule, an MIS you actually read, a cash forecast you trust, a live compliance calendar and at least one decision that the numbers changed. If you still have to ask your accountant what the monthly burn is, the engagement is not working yet, and that is worth saying plainly at the quarterly review.
It helps to write the day-90 review into the engagement letter from the start. Both sides then know the review will happen and what will be measured, and the scope can be reset once the clean-up phase is over and the monthly rhythm is running. A good virtual CFO will ask for that review rather than avoid it.
Frequently asked questions
What does a virtual CFO do that an accountant does not?
An accountant records transactions and files returns. A virtual CFO reviews that work, designs the close, the MIS and the cash forecast, and uses them to advise on pricing, hiring, spending and fundraising. Most startups need both, with the virtual CFO supervising the accountant.
How much time does a virtual CFO spend on a startup each month?
It depends on the scope. The first 90 days are the heaviest because the base is being cleaned up; after that the engagement settles into a fixed rhythm of reviews, calls and reports. Agree deliverables and dates in the engagement letter rather than counting hours.
Can my statutory auditor also be my virtual CFO?
Generally no. Section 144 of the Companies Act, 2013 bars a company's auditor from providing it with accounting, bookkeeping and management services. Use separate firms so the audit stays independent.
When will I see the first MIS from a virtual CFO?
Once the books are reconciled, which in the plan above is the second month. An MIS produced in week one from unreconciled data looks fast but is often wrong, and it teaches the founder to distrust the numbers.
