Accounting

Accounting for startups

Short answer

Accounting for startups from Finbryn sets up the chart of accounts and accounting policy at formation, not after a raise forces the issue, so a US startup's books are accrual-ready under GAAP from month one. Burn rate and runway track alongside standard statements, staying consistent with the cap table in Carta.

Illustrative. An example of the document, not a client's figures.

Most startups do not build their books wrong on purpose. They build them fast, because the first eighteen months are about the product and the first customers, and accounting is whatever gets the bills paid and the founder's own sanity intact. The problem shows up later, usually right when it is most expensive to fix: a raise is underway, a diligence request lands, and eighteen months of transactions need to be reconstructed and explained under a deadline that has nothing to do with accounting.

The fix is not more effort later, it is starting correctly at formation. A chart of accounts built for how the business actually spends money (not a generic template pulled from whatever software the founder signed up for), a written policy on when the books move from cash to accrual, and a bookkeeping cadence that runs every month from day one. None of this is expensive to set up early. All of it is expensive to reconstruct.

Investors, and eventually an auditor if the company gets large enough to need one, expect books that were built correctly, not patched together the week before a term sheet. Keeping the books accrual-ready from month one, even before an accrual basis is strictly required for tax purposes, means a future raise or review starts from a working file instead of a scramble. This matters more than founders expect: a data room with clean historical financials moves faster through diligence than one where every number needs a follow-up question.

Standard financial statements matter, but they are not the numbers a venture-backed founder actually watches week to week. Burn rate, how much cash the company is spending net of revenue each month, and runway, how many months of cash remain at the current burn rate, are the numbers that drive real decisions: when to raise, how much to raise, and how long a delay the company can actually absorb. We track both alongside the standard profit and loss, balance sheet, and cash flow statement, so the accounting function speaks the language investors and board members actually use in an update.

Equity gets messy fast in a startup: option grants, SAFE or convertible note conversions, a new priced round, sometimes a secondary sale. We do not manage the cap table itself, that sits with legal counsel or a dedicated cap table platform, but we keep every related accounting entry consistent with what the cap table shows, so the two do not quietly diverge from each other the way they often do when nobody is watching both sides.

R&D tax credit documentation is worth flagging early rather than reconstructing at filing time. A qualified small business can apply the federal research credit against payroll tax rather than income tax, against payroll tax rather than income tax under current law, which matters directly to a pre-revenue or early-revenue startup with real income tax liability but real payroll costs. We track the underlying qualified research expenses as part of normal bookkeeping so the documentation exists when your tax preparer files Form 6765, rather than being assembled retroactively.

As the business grows, this connects into full-service outsourced accounting for the broader ongoing function, and into fundraising financial models once the immediate need shifts from clean historical books to forward-looking numbers for a raise.

What is included

A chart of accounts built for a startup's actual spending pattern, engineering payroll, cloud infrastructure, customer acquisition cost, rather than a generic small-business template. A written accounting policy covering basis (cash versus accrual), revenue recognition, and how equity-related transactions get recorded. Monthly bookkeeping and close from formation forward, so there is no backlog to reconstruct later. Burn rate and runway tracked and reported alongside standard financial statements. Equity-related entries, option grants, note conversions, new round proceeds, kept consistent with the cap table your legal counsel or platform maintains. Underlying documentation for qualified research expenses tracked as part of normal bookkeeping, ready for your tax preparer at filing time.

How the process works

We start at formation, or as close to it as we are engaged: setting up the chart of accounts, the accounting policy, and the software stack before the first transaction is recorded, so nothing needs retrofitting. Each month runs the same close: bank and card reconciliation, revenue and expense categorization against the chart, burn rate and runway calculated from the actuals, and a standard financial statement set delivered on schedule. Equity events, an option grant, a SAFE conversion, a new round closing, get their own review pass to confirm the accounting matches what the cap table now shows. Once the company approaches a raise or a diligence process, we prepare the historical financials into a data-room-ready format ahead of the request rather than in response to it.

Who this is for

Any US startup that has raised outside money, plans to raise within the next year, or has hired beyond the founders. Pre-revenue is not a reason to wait; the moment a company has taken investor capital or brought on its first hires, the books need to hold up to a level of scrutiny that a founder's own spreadsheet was never built for. This fits venture-backed software and SaaS companies most often, but applies equally to any startup structure, a Delaware C corp, an LLC taxed as a partnership, that expects to raise or exit.

Common problems we fix

The most frequent issue is books that were kept accurately enough for the founder's own purposes but were never built to survive an outside reviewer, missing supporting documentation, inconsistent categorization month to month, or a chart of accounts that does not map cleanly to how investors expect a SaaS or product company to report. The second is equity accounting that has quietly diverged from the cap table, usually after a note conversion or a new round where the accounting entry was made months after the legal paperwork closed. The third is burn rate and runway calculated informally in a spreadsheet that does not tie back to the actual bank balance and monthly actuals, which erodes trust with the board the first time the numbers do not match.

Burn rate, runway, and the board update

A profit and loss statement tells you whether the company is profitable. For a venture-backed startup that is usually not the point yet. Burn rate, net cash spent per month, and runway, months of cash remaining at that rate, are the numbers a board actually wants in every update, because they answer the question that matters: how much time does the company have, and does that timeline match the plan discussed at the last raise. We calculate both from actual bank activity, not a projection, and present them in the same board-ready format investors expect to see across their portfolio, so an update does not require translation.

Software and integrations

QuickBooks Online and Xero cover most early-stage startups well, with Ramp, Brex, or Mercury handling card spend and syncing directly into the ledger. As transaction volume and headcount grow, NetSuite becomes the more common landing point, particularly once multi-entity structures or more complex revenue recognition enter the picture. We set up whichever stack fits the company's current stage rather than over-building tooling a five-person company does not need yet.

What it costs

Pricing depends on transaction volume, entity structure, and how much investor-facing reporting (burn, runway, board packs) is included alongside standard bookkeeping and close. Startup engagements often start smaller and scale with headcount and funding stage. Current tiers and the point at which a company moves into a higher plan are published on the pricing page, with your exact scope confirmed in writing before work begins.

How we work

The process

  1. 1

    Formation-stage setup

    Chart of accounts, accounting policy, and software stack are built before the first transaction, so there is nothing to retrofit later.

  2. 2

    Monthly bookkeeping and close

    Bank and card activity is reconciled and categorized every month from day one, keeping the books current rather than accumulating a backlog.

  3. 3

    Burn rate and runway reporting

    Net cash burn and months of remaining runway are calculated from actuals and delivered alongside standard financial statements.

  4. 4

    Equity and cap table consistency check

    Option grants, conversions, and new round proceeds are reviewed against the cap table each time an equity event occurs.

  5. 5

    R&D expense tracking

    Qualified research expenses are tagged during normal bookkeeping so the documentation exists when your preparer files for the credit.

  6. 6

    Pre-raise or pre-diligence readiness

    Historical financials are packaged into a data-room-ready format ahead of a raise or review, not scrambled together once the request lands.

Accounting for startups

Common problems we fix

  • Books were kept for the founder's own tracking but were never built to survive an outside reviewer
    We rebuild the chart of accounts and reconstruct supporting documentation to a standard that holds up in investor or auditor review.
  • Equity accounting has drifted from what the cap table actually shows after a note conversion or new round
    We review every equity event against the cap table and correct the accounting entries so the two are consistent again.
  • Burn rate and runway are tracked informally and do not tie to the actual bank balance
    We calculate both directly from bank and card activity each month, so the number in the board update matches reality.
  • A raise is underway and historical financials are not ready for a data room
    We package the historical statements and supporting schedules into a format investors and their counsel can review quickly.

Pricing

Startup accounting is priced on transaction volume, entity structure, and how much investor-facing reporting is included alongside standard bookkeeping. Early-stage engagements typically start on a lower tier and scale with headcount and funding stage. Current tiers are published on the pricing page, and exact scope is confirmed in writing before work begins.

Questions

Frequently asked questions: Accounting for startups

We are pre-revenue. Do we need real accounting yet?

Once you have raised outside money, hired anyone, or plan to within the next year, yes. Investors and future auditors expect books that were built correctly from the start, not reconstructed under deadline pressure.

Do you set up our cap table?

No. Cap table management is typically handled by your legal counsel or a dedicated cap table platform. We keep the accounting side, including any related equity transactions, consistent with what the cap table shows.

How early is too early to start?

Rarely too early. The cost of setting up correctly at formation is far lower than the cost of a catch-up and cleanup engagement right before a raise or a diligence review.

Do you help with R&D tax credit documentation?

We track the underlying qualified research expenses during normal bookkeeping so the documentation exists when your tax preparer files Form 6765. The credit itself is calculated and filed by your credentialed tax preparer.

Do you calculate burn rate and runway for us?

Yes. We calculate both from actual bank and card activity each month and deliver them alongside your standard financial statements, formatted for a board update.

What happens to our books once we close a priced round?

We review the round's accounting entries against what your legal documents and cap table show, confirm they are consistent, and typically that is the point where a company scales into a higher service tier as headcount and complexity grow.

Can you help prepare financials for investor due diligence?

Yes. We package historical financials, reconciliations, and supporting schedules into a format that moves faster through an investor's or their counsel's review, ideally prepared ahead of the request rather than in response to it.

Do you work with both Delaware C corps and LLCs?

Yes. Most venture-backed startups incorporate as a Delaware C corp, but we also work with LLC structures, including the different tax and equity treatment each structure requires.
