Accounting for Startups,
Handled End to End

What accounting for startups actually is

Accounting for startups is the practice of recording, classifying and reporting a company's finances around the events that define an early venture-backed business: raising money, spending it before revenue exists, and proving to investors and tax authorities that the numbers are right. It differs from small-business accounting in what it has to explain.

A restaurant's books answer one question: did we make money this month. A startup's books answer a harder one, which is how long the company survives at its current spend, and whether the money that arrived was revenue or financing. Getting that second distinction wrong is the most common and most expensive mistake we see in books we take over.

Never kept books before? Start with basic accounting for startups: how an entry works, the five kinds of account, and the monthly routine. For the recurring work itself and what it costs, see bookkeeping for startups.

Your first deadline arrives before your first customer

Most founders assume accounting starts when money starts moving. It starts at incorporation. If you take founder stock subject to vesting and want to file an 83(b) election, you have 30 days from the grant date, and the IRS does not grant extensions for missing it. That single form, filed or missed in your first month, can be the difference between paying tax on stock at a fraction of a cent and paying it at a later valuation.

Delaware corporations then owe franchise tax and an annual report by 1 March every year, whether or not the company has revenue. The notice Delaware sends uses the authorized shares method, and for the standard 10,000,000-share startup that produces a bill of $85,165 in tax plus the $50 annual report fee, or $85,215. Almost nobody owes it. Recalculated on the assumed par value capital method, which the Delaware Division of Corporations permits, a company with $500,000 of gross assets and 8,000,000 issued shares owes the $400 minimum plus the same $50 fee. That is $450 against $85,215, and the only thing standing between the two numbers is knowing the second method exists.

What to track from day one

The list is shorter than most guides make it. You need every bank and card account feeding in automatically, so nothing is reconstructed from memory later. You need receipts and invoices attached to the transactions they belong to, because a deduction you cannot evidence is a deduction you lose under examination. You need payroll, including contractor payments that will become 1099s in January. You need your cap table and every financing document, because those determine how the largest inflows are recorded. And you need a record of which state you have employees in, since that creates registration and filing obligations most founders discover late.

What you do not need in year one is a general ledger you maintain by hand, a month-end close checklist copied from a mid-market finance team, or a chart of accounts with 200 lines in it.

The three statements, and the one investors read

The income statement shows revenue and expenses over a period, and answers whether the business made money. The balance sheet shows what you own and owe at a single moment, and is where your SAFEs, notes and equity live. The cash flow statement reconciles the two by showing where cash actually moved.

For a pre-profit company the income statement is the least interesting of the three. Your board and your next lead investor are reading for burn and runway, which come out of cash flow, and for the balance sheet treatment of your financing instruments, which is where diligence tends to find problems. A startup that reports a tidy profit because a SAFE landed in revenue has not produced good news. It has produced a correction and, potentially, a tax bill on money it did not earn.

The burn rate and runway calculator turns those numbers into the month your cash runs out.

Cash or accrual

Cash basis records a transaction when money moves. Accrual basis records it when it is earned or incurred, regardless of when it settles. Cash is simpler and is where most startups reasonably begin.

Two things end that. Investors and lenders generally expect accrual-basis financials by the time you raise a priced round, because accrual is the only basis that shows a subscription business honestly: twelve months of prepaid annual contracts is not twelve months of revenue. And the tax code eventually requires it. Companies with inventory, and those above the IRS gross receipts test (a threshold indexed for inflation each year), must use accrual. The practical answer is to keep books that can produce either view, and to treat the switch as a reporting change rather than a rebuild.

A chart of accounts that survives diligence

A chart of accounts is the list of categories every transaction gets filed into. The failure mode is not having too few, it is having categories that mean different things in different months. Consistency matters more than granularity, because the value of the ledger is comparison over time.

A startup chart needs a few things a generic template will not have: separate accounts for each financing instrument rather than one lump "investment" line, research and development expense split finely enough to support an R&D credit claim, deferred revenue if you invoice annually, and contractor spend separated from employee payroll so 1099 season is a report rather than an investigation.

Fundraising is not revenue

This is the error worth repeating. A SAFE, a convertible note and a priced round are financing events. They increase cash and they increase a liability or equity line. None of them is income, and none belongs on the income statement.

Recording a $2,000,000 SAFE as revenue makes a pre-revenue company look profitable, invites a corporate tax bill on money that was never earned, and guarantees that the first serious diligence process starts with restating prior years. It happens because generic bookkeeping software sees a large deposit and the person categorising it has never seen a SAFE. The fix is structural: the financing documents have to be part of the bookkeeping process, not filed separately in a data room.

The same logic covers the credits founders leave unclaimed. Qualified small businesses can apply up to $500,000 of federal R&D credit against payroll taxes each year, which is cash back while still unprofitable. Claiming it requires payroll and vendor data classified correctly during the year, not reconstructed the following March.

What startup accounting costs

Four realistic options, and the honest trade-off in each.

The number that matters is not the monthly fee. It is the monthly fee plus the returns plus whatever a missed credit or a restated year costs you during a raise.

When to bring someone in

Before your first tax season, and ideally in the month you incorporate. The reason is not bookkeeping volume, which is trivial at the start. It is that the decisions with the longest tails, 83(b) timing, entity type and state, how your first financing is recorded, whether you are set up to claim R&D, all happen in the first few months and are expensive to unwind later.

Cleaning up a year of neglected books always costs more than keeping them clean, and the cleanup always seems to land in the same fortnight as your term sheet.
