Bookkeeping for startups has one main job: produce a monthly burn figure that founders and investors can trust. That means recording funding as equity or debt rather than revenue, coding software and card spend consistently, booking payroll from the provider's register, and closing every month on time so cash, burn and runway agree with the bank.
Recording a startup funding round in the books
A startup funding round is never income. Money from a priced equity round goes to equity accounts. Money raised on a SAFE or a convertible note goes to its own clearly named account, because its final classification depends on the instrument's terms and is a decision for the startup's accountant. Coding a raise as revenue makes every later report wrong.
The bank line for a raise is usually one large incoming wire, sometimes several from different investors over a few days. Record each wire against the investor's name, then tie the total to the closing documents: the stock purchase agreement, the SAFE agreements or the note documents. Keep copies with the month's records.
A clean set of accounts for funding:
- Common stock and additional paid-in capital, for founder purchases and priced rounds.
- Preferred stock, for priced rounds that issue preferred shares.
- SAFE proceeds, one account, with a list of holders and amounts kept outside the ledger.
- Convertible notes payable, with accrued interest if the notes carry it.
Investor wires sometimes arrive net of a bank's incoming wire fee. Record the full amount the investor sent as funding and the bank fee as an expense, so the funding total matches the legal documents exactly.
Grants and startup competition prizes are different again. They are not equity, and their tax treatment varies. Give them their own income or other income account and flag them for the accountant.
Software subscriptions on a startup's card statements
Software subscriptions are the most frequent line on most startup card statements. Hosting, code tools, design tools, analytics, email and team chat each bill monthly, often to several cards held by different founders. The bookkeeping goal is consistency: the same vendor, the same account, every month, with annual prepayments spread across the year they cover.
Group software into accounts that a founder can act on:
- Hosting and infrastructure, for cloud servers, databases and content delivery.
- Software tools, for per-seat productivity and engineering tools.
- Sales and marketing software, for CRM, email marketing and ad tools.
Cloud hosting deserves its own line because it grows with usage, and founders watch it closely. Some startups go further and split hosting into production and development, which helps if the company later wants to calculate gross margin.
Annual plans and prepaid software
An annual plan paid in January covers twelve months. On cash basis the whole charge lands in January. On accrual basis it goes to prepaid expenses and is spread monthly. Either way, note large annual charges in the month they hit, because they make a single month's burn look worse than the trend.
Card statements also carry refunds, foreign currency charges and the occasional duplicate trial charge. Convert every company card statement each month, not just the main one. AutoBankConvert takes checking and card statements from different banks in one upload and codes recurring vendors from rules the startup's coding history has already taught it.
Payroll and contractor payments in startup bookkeeping
Payroll reaches a startup's bank statement as a few large provider withdrawals: net pay, taxes, sometimes benefits. The statement does not show who was paid or what was withheld. Book payroll from the provider's payroll register, splitting each run into gross wages, employer taxes, benefits and the cash that left the account.
A typical semi-monthly run, as an example:
| Register line | Amount | Account |
|---|---|---|
| Gross wages, engineering | 38,000.00 | Salaries, engineering |
| Gross wages, sales | 12,000.00 | Salaries, sales and marketing |
| Employer payroll taxes | 3,825.00 | Payroll taxes |
| Employer health contribution | 4,100.00 | Employee benefits |
| Total cash withdrawn by provider | 57,925.00 | Matches the statement lines |
Splitting wages by team is a small extra step that investors often ask for later. It is easier to set up in the first month than to rebuild after a year.
Contractors are paid differently. A developer abroad paid through a contractor platform, or a designer paid by bank transfer, shows as a single line. Code these to contract labor, by team if you split wages by team, and keep the contractor's invoice. If equity is granted to employees or advisors, the accounting for stock compensation is a job for the accountant, but the bookkeeper should keep the grant list on file.
How do you calculate a startup's monthly burn from the books?
A startup's monthly burn is the cash the company spends in a month. Gross burn is total cash out from operations. Net burn is gross burn minus cash in from customers. Runway is the cash balance divided by net burn, expressed in months. All three come straight from reconciled bank and card statements.
A worked burn calculation
Here is an example for one month. All figures are illustrative.
| Line | Amount |
|---|---|
| Payroll and benefits | 115,850.00 |
| Contract labor | 14,200.00 |
| Hosting and infrastructure | 9,640.00 |
| Software tools | 3,310.00 |
| Rent and coworking | 4,500.00 |
| Other operating costs | 6,500.00 |
| Gross burn | 154,000.00 |
| Customer receipts | 38,000.00 |
| Net burn | 116,000.00 |
| Cash at month end (all accounts) | 1,740,000.00 |
| Runway at this net burn | 15 months |
Keep funding wires, loan proceeds and transfers between the startup's own accounts out of the burn. They change cash, but they are not operating spending or customer revenue. A transfer from checking to a high-yield savings account is the classic error: coded as an expense, it inflates burn for the month.
Checks before a startup's burn figure goes out
Run four checks before sending burn to founders or a board. Every bank and card account is reconciled to its statement for the month. Funding wires and inter-account transfers are coded outside operating accounts. Each payroll run is booked from its register, not as one lump. Annual charges over a set size, say 5,000.00, are noted so a spike has an explanation. A burn figure that passes these is one an investor can compare month to month without asking how it was built.
Customer receipts also need care. A startup that sells annual contracts may collect a full year's payment in one month, which flatters that month's net burn. Report it, but show founders the trend over several months too. Startups that sell physical products face inventory timing as well, which retail store bookkeeping covers in more detail.
Founder-paid expenses from before the startup's bank account
Founder-paid expenses are costs a founder covered personally, often before the company was formed or before it had its own card: incorporation fees, a domain, early hosting, a first laptop. They belong in the company's books only once there is a record of the cost and a decision on how the founder is repaid.
There are two common ways to record them:
- Reimbursement. The founder submits receipts, the company pays them back from its account, and each cost goes to the right expense or asset account.
- Contribution. The company records the costs as expenses and the founder's payment as a capital contribution, with no cash paid back.
The mistake is to do neither. Costs paid personally and never recorded leave the startup's early spending understated. Costs reimbursed as a round-number transfer with no receipts leave an unexplained payment to a founder, which a due diligence review will ask about.
Founders who run a side business, such as a short-term rental, sometimes pay startup costs from that account too. Keep those lines out of the other business's books; short-term rental bookkeeping covers that kind of property income on its own.
Is cash-basis bookkeeping enough for a startup?
Cash-basis bookkeeping is enough for many very early startups, when there is no revenue, no prepaid contracts and no outside investors asking for financial statements. It stops being enough once the company sells annual plans, owes significant bills at month end or raises a priced round whose investors want accrual reports.
Signs it is time to move to accrual:
- Customers pay upfront for service delivered over months, so cash receipts no longer match what was earned.
- Large bills, such as annual software or legal fees, distort single months.
- Investors, a board or a lender ask for monthly financial statements prepared on an accrual basis.
- An audit or review is likely within the next year or two.
Moving to accrual adds a few recurring entries each month: deferred revenue for prepaid customer contracts, prepaid expenses for annual software, and accrued bills for work received but not yet invoiced. None of these come from the bank statement directly. They come from contracts and invoices, which is why a startup that plans to switch should start filing those documents by month now.
The switch is easier with clean cash books underneath. Bank and card lines coded the same way each month give the accrual entries a reliable base.
Many startups hand bookkeeping to an outside team from the start, and working with a remote bookkeeping team covers how to share statements and questions with one. If you are that team, AutoBankConvert can turn each startup's monthly pile of bank and card statements into categorized export files, so your time goes to funding entries, payroll splits and the burn report.
