How to keep your books investor-ready for due diligence: a 12-check list and the data room export

Your books are investor-ready when every month is reconciled to the bank, the income statement, balance sheet and cash flow agree with each other, and you can hand over the ledger and supporting documents in one package. Mercury's checklist lists statements, monthly and quarterly history, bank records, revenue detail and a cap table, then tax filings, payroll and contracts later. Accountable builds that package as one data room zip.

The short version

Mercury's investor-ready checklist (September 24, 2026) names the income statement, balance sheet, cash flow, monthly and quarterly history, bank and card records, revenue detail and a cap table.
Later in diligence investors may also ask for tax filings, payroll records, contracts, debt agreements and equity documents.
Diligence goes faster when each month is reconciled to the bank and records are accurate, current, consistent and easy to explain.
Accountable's data room export builds one zip with statements, general ledger, trial balances, reconciliations, documents, change log and chart of accounts, free on every plan.
AI keeps the books current; your CPA still prepares tax filings and your lawyer keeps the cap table and contracts.

Investors ask for seven things first and five more as diligence goes on

The first list below comes from Mercury's investor-ready guide. The second is what Mercury says investors may request as diligence progresses. The last column says where each item lives in Accountable.

What investors ask for in financial due diligence, and where it comes from in Accountable
Item	What the investor wants to see	Where it comes from
Income statement	Revenue, expenses and profit or loss over a period	Reports › Profit and loss, on cash, accrual or both
Balance sheet	Assets, liabilities and equity at a date	Reports › Balance sheet
Cash flow	How cash moves and how long it lasts	Reports › Cash flow, plus burn and runway on Home
Monthly and quarterly history	Trends, not only annual totals	Every month from your first one, locked when finished
Bank and card records	Balances and transactions that match the statements	Reconciliations in the data room export
Revenue detail	Revenue by customer or contract	Revenue accounts and customers in the general ledger
Cap table	Founders, investors, employees and equity holders	Not in your books: your lawyer or cap table tool
Tax filings	Federal and state returns	Your CPA; the ledger and statements are what they work from
Payroll records	Payroll by month	Payroll reports from Gusto or Rippling, posted to the ledger
Contracts and debt agreements	The paper behind revenue, loans and equity	Documents attached to entries, and your lawyer's files

Twelve checks to pass before you send anything

Step 1: Every bank and card account is reconciled for every month, with a difference of $0.00 (see how to reconcile a bank account).
Step 2: No transaction is left uncategorized or sitting in a suspense account.
Step 3: Finished months are locked, so the numbers you send today are the numbers you send next week.
Step 4: The P&L and balance sheet are on the accrual basis, and your cash view agrees with the bank (see cash and accrual side by side).
Step 5: Annual prepayments are in deferred revenue, not revenue (see deferred revenue for SaaS).
Step 6: Each payroll run matches the payroll report, including taxes and benefits.
Step 7: Contractor payments are tracked for Form 1099-NEC (see the 1099-NEC guide).
Step 8: Receipts and contracts are attached to the entries they support.
Step 9: Loans, SAFEs and equity entries match the signed documents.
Step 10: Balances between your own companies are matched and eliminated (see intercompany transactions).
Step 11: The change log shows who changed what, so any number can be explained.
Step 12: Your CPA has read the statements before an investor does.

Mercury's own summary of the standard is that records should be accurate, current, consistent and easy to explain. Twelve checks are one way to test each of those four words.

AI keeps the records current; people still own the legal and tax paper

AI does: categorizing every transaction, checking each account against the bank, posting recurring entries and preparing each month's statements.
You do: approve what the AI cannot decide, and keep the cap table and signed documents current.
Your CPA does: prepares and signs tax filings and advises on elections; read what AI replaces and what your CPA still does.

Questions founders ask

What financial documents do investors ask for in due diligence?

Mercury lists the income statement, balance sheet, cash flow, monthly and quarterly history, bank and card records, revenue detail and a cap table. Later requests add tax filings, payroll records, contracts, debt agreements and equity documents.

How many months of history do investors want?

Mercury does not give a number. It says to show monthly and quarterly statements so trends are visible, so start from your first month and keep every month reconciled.

Should my books be on the accrual basis for investors?

Usually yes: US GAAP statements are prepared on the accrual basis. Keep a cash view too, because burn and runway are cash numbers.

What is a data room export?

One zip with the statements, ledger, reconciliations and documents for the months you choose. Accountable builds it from ⌘K › Export data room, and it is free on every plan.

Can AI make my books investor-ready?

AI keeps the records current and reconciled, which is most of the work. Tax filings, the cap table and legal documents still come from your CPA and lawyer.
