Scaling your business finances: what has to change at 10, 50 and 150 people

Scaling a company's finances means changing four things as it grows: the accounting basis (from cash toward accrual, with revenue recognized when earned), the controls (from the founder approving everything to written approval limits and separated duties), the tax footprint (from one state to payroll and sales tax in many), and the reporting cadence (from 'when we need it' to a monthly close in days, then audited annual statements). Each change is cheap to make a little early and expensive to make late, usually in the middle of a fundraise or a diligence request.

Headcount is a rough proxy for when each change bites. Here's what typically changes at each stage, and the signal that tells you it's time.

What should finance look like with fewer than 10 people?

At this stage the goal is clean, current books and not much more:

• Separate business accounts and cards, with nothing personal running through them.
• Every account connected and reconciled monthly to the statement.
• A monthly close within about a week of month-end, even if it's the founder and a part-time bookkeeper doing it.
• Investor money recorded correctly: SAFEs and priced rounds in liabilities or equity, never revenue. See how to account for SAFEs.
• A simple cash forecast and a monthly look at burn and runway.

Cash-basis books can be adequate here for internal use. The moment you sell annual contracts, raise a priced round, or take on a lender, you'll need accrual statements.

What changes between 10 and 50 people?

Revenue recognition gets real

Under ASC 606, the US GAAP revenue standard, revenue is recognized as you deliver the service, not when you bill or collect. For a subscription company with annual contracts that difference is large.

Worked example (hypothetical): a company with $3 million of annual recurring revenue bills most of its customers annually in January. In January it invoices $1.2 million of renewals and collects most of it by February.

• On a cash basis, January or February shows a $1.2 million revenue spike and the rest of the year looks weak.
• On an accrual basis, those renewals contribute $100,000 a month for twelve months, and the $1.2 million sits in deferred revenue on the balance sheet, falling by $100,000 each month.

Investors and acquirers will look at the accrual numbers. If your history is on a cash basis, someone will have to rebuild it, usually under deadline.

Controls replace trust

With three people, the founder sees every payment. With thirty, that isn't possible, and the controls that matter are simple:

• Approval limits in writing. For example: managers up to $2,500, a department head up to $25,000, the CEO above that.
• Separate duties. The person who adds a new vendor or changes bank details shouldn't be the person who approves payment to that vendor. Changed bank details should be confirmed by phone, using a number you already have.
• Two-person rule for wires above a threshold.
• Locked periods after the monthly close, so reported numbers can't change silently.

The tax footprint spreads

Remote hiring creates payroll registration, withholding and often income or franchise tax obligations in every state where an employee works. Sales are similar: since the Supreme Court's 2018 decision in South Dakota v. Wayfair, states can require out-of-state sellers to collect sales tax once they pass an economic threshold, even with no physical presence. South Dakota's law at issue used $100,000 of sales or 200 transactions into the state. Many states adopted thresholds of their own, and whether software or services are taxable varies by state. Track sales by customer state from the start; finding out two years late means back taxes you didn't collect from customers.

Who should own finance?

Usually a strong bookkeeper plus a part-time or fractional controller or CFO. The controller owns the close, revenue recognition and controls; the CFO role at this size is mostly forecasting, fundraising support and board reporting.

What changes between 50 and 150 people?

• Audited financial statements. Later-stage investors, lenders and acquirers commonly ask for them. A first audit is much easier if the prior year's balance sheet is already reconciled and supported, account by account.
• A faster close. Five to ten business days is a reasonable target. Each extra day delays every decision that depends on last month's numbers.
• Real budgeting and forecasting. Department owners get budgets, and a monthly variance review explains differences. A driver-based forecast becomes a team process rather than a founder's spreadsheet.
• Equity administration. Option grants are typically priced off a current independent 409A valuation, and need accurate vesting records and a cap table that agrees with the legal documents.
• A full-time finance lead, and usually a dedicated accounts payable and payroll function.

What are the warning signs that your systems are behind?

• The close takes more than three weeks, or doesn't happen at all some months.
• Cash in the books doesn't match the bank, and nobody is sure why.
• Revenue reported to the board differs from revenue in the books.
• You can't produce a list of every contractor paid more than $2,000 this year in under an hour.
• Investors' diligence questions take days to answer because the answer requires reconstructing old transactions.
• One person is the only one who knows how payroll, bill pay or the bank logins work.

What is the right order to fix things?

If several of those signs apply, fix them in this order, because each step depends on the one before:

1. Reconcile cash in every account to the bank, back to the last point you trust. Everything else rests on this.
2. Fix classification: investor money, loans, transfers between your own accounts, and capitalized assets.
3. Move to accrual, at least for revenue and major expenses, and set up deferred revenue.
4. Write down controls and turn on period locking.
5. Register for state taxes where you have employees or have crossed sales thresholds.
6. Then add budgeting, forecasting and audit preparation.

Does growing mean switching accounting software?

Not necessarily, but the software must support accrual reporting, period locking, user roles, and an audit trail of who changed what. It also helps a great deal if the cap table and investor reporting live near the books, so a fundraise doesn't mean reconciling three systems.
