Accounting for startups: What to set up, when to outsource, and what investors need to see

What accounting to set up before your first hire, when to switch to accrual basis, and what Series A investors check before they sign. A practical guide for founders at every stage.

34.7 percent of business establishments born in 2013 were still operating ten years later, according to BLS Business Employment Dynamics data. 1.3 million new establishments opened in the United States in 2023. The ones that make it are rarely better at the product than the ones that do not. They are better at the financial infrastructure underneath it.

This guide covers what accounting means for a startup at each stage, what to set up before you hire your first employee, and what investors check in a data room. For the question of when an accountant becomes a CFO, see CPA vs CFO.

What does startup accounting actually cover

Accounting is not bookkeeping, though founders often use the terms interchangeably. Bookkeeping records what happened: transactions coded, bank accounts reconciled, invoices logged. Accounting uses those records to produce financial statements, file tax returns, and tell the story of the business in numbers. A CFO uses those statements to make decisions about the future. The three functions are distinct, and a startup needs all three at different points in its growth.

The other foundational choice is the accounting method. Cash basis accounting records revenue when cash arrives and expenses when cash leaves. Accrual basis accounting records revenue when it is earned and expenses when they are incurred, regardless of when cash moves. Most startups begin on a cash basis because it is simpler. Most Series A investors require accrual-basis books because cash basis financials do not give an accurate picture of a SaaS company's true performance.

What to set up before you hire your first employee

Three things should be in place before a startup takes on its first payroll or signs its first customer contract.

A business bank account, separate from any personal accounts, is the first. Businesses must keep records to support the items reported on their tax returns, and commingling personal and business funds makes that requirement impossible to meet cleanly.

A chart of accounts is the second. This is the master list of categories the accounting system uses to record every transaction. Getting it right at the start takes half a day. Rebuilding it eighteen months later, when an investor asks for three years of reclassified financials, takes weeks.

Accounting software is the third. The specific platform matters less than the discipline of using one consistently. The books need to be reconciled monthly, not quarterly, and the accounting software is what makes that possible.

When should you move from DIY to outsourced accounting

Three signals consistently mark the point where founder-managed accounting creates more risk than it saves in cost.

The first is when the monthly close takes more than two days. A close that drags into the second week means either the volume of transactions has outgrown the founder's bandwidth or the chart of accounts needs restructuring. Either way, the books are not reliable enough for investor reporting.

The second is when the company sells on annual contracts or has more than one revenue stream. Revenue recognition under FASB ASC 606 requires matching revenue to the period it is earned. Getting this wrong does not produce just inaccurate financial statements, it creates a restatement risk that surfaces at the worst possible time, typically mid-fundraise.

The third is twelve months before a fundraise opens. Investors check the books before they sign a term sheet, not after. For a detailed breakdown of what they look at and in what order, see how to prepare your financials for a Series A raise.

What investors need to see before they sign

Three things come up in every data room review that founders consistently underestimate.

Accrual-basis financials are the first. Cash basis books do not show deferred revenue, accounts receivable, or the true gross margin of a SaaS business. Investors model on accrual figures. If the books are on a cash basis, the CFO converts them before the process opens.

Clean revenue recognition is the second. A company that has been recognising annual contract revenue upfront rather than ratably will need to restate under FASB ASC 606. Investors see this immediately and it delays the process by weeks.

Audit-ready financials are the third. Series B investors frequently require two years of audited financial statements. The audit is not the work, the work is building the financial close process clean enough that an audit does not require significant rework. That takes time to build, not weeks but quarters.

The cost of getting accounting wrong

Getting the accounting function right from the start costs a fraction of what it costs to rebuild it under time pressure eighteen months later, when an investor is waiting for clean books.
