StartupsStartup Accounting: The First-Year Setup Founders Usually Skip

Ask a founder for their priorities in month one and you'll get a list like this: ship the product, talk to users, hire an engineer, raise a round, figure out why the staging server is on fire. Accounting is in there somewhere. Around item 47, just after "buy a better office chair."

Fair enough. Nobody starts a company to reconcile a credit card. But startup accounting has a funny property: the setup takes a few hours in month one, and skipping it takes weeks to undo in month eighteen, usually right when an investor's diligence team asks for clean financials.

Here's the first-year setup founders usually skip, in the order that saves the most pain later.

Step one: separate everything, immediately

Open a business bank account and a business credit card in the company's name the moment the entity exists. Run every company expense through them and nothing personal.

If you paid for things personally before the account was open (incorporation fees, a domain, the first laptop), keep the receipts and record those as either a reimbursement to you or a founder contribution. Your accountant can help pick the right treatment. What you want to avoid is a year of company expenses scattered across three personal cards, because untangling that later is like sorting a junk drawer while someone times you.

Step two: set up the software properly

Choose accounting software, connect the bank feeds, and build a chart of accounts (the list of categories every transaction gets sorted into) that fits a startup. That usually means separating:

• Revenue by type (subscriptions, services, one-time fees).
• Cost of revenue, such as hosting and payment processing, from operating expenses.
• Operating expenses into research and development, sales and marketing, and general and administrative.

That last split is what investors and boards expect to see, and building it in from day one avoids reclassifying a year of transactions later. The setup order matters more than people expect; our guide to QuickBooks Online setup for small business walks through it step by step.

Step three: pick accrual accounting early

Cash basis records income when money arrives and expenses when money leaves. Accrual basis records income when it's earned and expenses when they're incurred, regardless of when cash moves.

Many startups begin on cash because it's simpler. Then they raise money, and investors (and any future auditors) want accrual-based financials. Switching later means restating history. Your CPA decides which method you use for tax purposes; for your management books, accrual is usually the better starting point if you plan to raise money or sell annual contracts.

A worked example: the December that looked amazing

Say you run a hypothetical B2B software startup. In December you sign ten customers to annual contracts at $12,000 each, all paid upfront. That's $120,000 in the bank.

On a cash basis, December revenue is $120,000. Your P&L looks like you just had the best month in company history, and every month after it looks like a collapse.

On an accrual basis, you record the $120,000 as deferred revenue (a liability that represents service you still owe customers) and recognize $10,000 a month for twelve months as the service is delivered. December revenue is $10,000. So is January. Your monthly recurring revenue chart now tells the truth.

Same cash, two very different stories. Investors will want the accrual version.

Step four: keep fundraising and equity records clean

Every financing document has an accounting entry behind it. Common first-year items:

1. Founder stock purchases and any founder loans to the company.
2. SAFEs or convertible notes, recorded on the books when the cash comes in.
3. Option grants, which may require stock compensation accounting later on.
4. Legal and filing fees tied to the raise.

Keep signed copies of every agreement in one folder, and make sure the amounts in the books match the documents and the cap table. How some instruments are classified is a technical accounting question; your accountant and CPA should weigh in.

Founders also have tax and legal deadlines of their own, and those belong with your CPA and attorney. Ask them early which ones apply to you. ABFI doesn't do tax work; we make sure the books give your CPA accurate numbers.

Step five: close the books every month

This is the step that turns startup bookkeeping into something you can actually use. A monthly close means reconciling every account, recording accruals and deferred revenue, reviewing the results and locking the month.

With a closed month, you can calculate burn rate (how much cash you spend per month) and runway (how many months that cash lasts). Our guide to calculating burn rate and runway shows the formulas and what to do with them. A closed month is also the raw material for investor reporting for startups, which goes out a lot faster when the numbers are already reviewed.

Accounting for startups: who does what in year one

Most first-year startups don't need a full-time finance hire. A practical setup for accounting for startups looks like this:

• Bookkeeping: transactions, bills, payroll and reconciliations.
• Controller review: a monthly close, accruals and deferred revenue, and someone checking the work.
• CFO-level help: a budget, a runway model and fundraising support when you raise.
• An independent CPA: tax returns and tax advice.

ABFI's startup accounting service covers the first three layers as one department, with a Client Accounting Manager coordinating, and hands organized records to your CPA.
