Opening Balance Sheet After an Acquisition: 6 Things to Settle First
Sam's List Editorial | 2026-10-27
An opening balance sheet after an acquisition is the first set of books you own, and every report after it is built on it. If it starts wrong, the error follows you into every month, every tax return and every lender package.
The six items below are a checklist, not a ranking. The one firm written up is System Six, a Seattle bookkeeping and fractional CFO firm that helps organizations modernize a finance function after an acquisition. System Six is a vetted Sam's List member and a paying member of our featured program; payment does not buy the language we use or its reviews. You can read how we picked this firm at the end.
1. Pick the Closing Figures for Your Opening Balance Sheet After an Acquisition
Start from the closing statement or settlement statement and the final purchase agreement, not from the seller's last monthly report. The closing date is the line: balances on that date are what you bought, and anything before it was the seller's.
Ask which version of the closing balances is final. Many deals have a post-close adjustment, such as a working capital true-up, that changes the numbers weeks or months after closing. Record the opening balances as provisional if an adjustment is pending, and note which accounts it can touch.
The limitation: a closing statement is a deal document, not a set of books, and its categories may not match an accounting framework. Treat it as the source for amounts and your accountant as the source for how they are recorded.
2. Settle Acquisition Accounting for a Small Business: Which Assets and Debts You Actually Bought
Not every deal is the purchase of a company with all its balance sheet. In an asset purchase you buy listed items, such as equipment, inventory and customer contracts, and the seller keeps the rest. In a stock or equity purchase you generally take the company with its assets and its liabilities.
That difference decides what goes on your opening balance sheet. Read the schedules of the purchase agreement and list each asset, each liability assumed and each item excluded. Acquisition accounting for a small business starts as a list-making exercise, before it becomes a journal entry.
The limitation: deal structure also drives tax treatment, and the choice is usually made with counsel before closing. Your accountant can record what the agreement says; changing it afterward is generally not possible.
3. Handle Purchase Price Allocation Bookkeeping Before the First Close
The price you paid is generally spread across what you bought: equipment, inventory, receivables, any identifiable intangible items and what is left, usually called goodwill. How the price is split affects depreciation and amortization, and in some deals it is reported to the IRS on a form filed with the return.
Purchase price allocation bookkeeping means making sure the allocation in the agreement or in a later schedule is the one in your ledger. If the contract has an allocation, start there. If it does not, decide who prepares one, and whether a valuation professional is needed for larger or more complicated items.
The limitation: an allocation has tax and accounting consequences that differ, and the books should follow the final agreed schedule. Do not guess at percentages. Ask your CPA and, where it matters, your attorney.
4. Record Acquired Receivables, Payables and Deferred Revenue Carefully
Receivables you bought are only worth what you can collect, so ask for an aging report at closing and a view on old balances. Payables you assumed should be matched to invoices, since an unpaid bill the seller forgot will arrive in your name. Customer deposits and prepaid work you now owe are obligations you took on, even when you did not receive the cash.
Deferred revenue is the item people miss most. If customers paid the seller for service you will deliver, you inherit the work without the revenue. Record it so the work you do next quarter is not counted as new sales.
The limitation: which of these balances transfer depends on the structure in item 2. Confirm each one against the agreement instead of assuming.
5. Set Up Debt and the Seller Note, and Map the Seller's Chart of Accounts: Where System Six Fits
Two jobs sit at the back end of an opening balance sheet. The first is debt: a bank loan, a seller note, earnout terms and any guarantees each need an account, a schedule and the dates payments are due. The second is mapping the seller's chart of accounts to yours, so history and new transactions land in the same categories.
This is finance-function work, which is what System Six describes. It is a bookkeeping and fractional CFO firm based in Seattle, founded in 2009, with about 41 employees and serving clients nationwide. Its live profile lists Non-Profit Organizations, Professional Service Firms and Real Estate Investors as specialties. It says it serves small businesses generating between $1 million and $10 million of revenue and helps organizations modernize a finance function after an acquisition.
System Six does not yet have enough reviews on Sam's List for us to cite a count, so we describe the firm by what its profile says instead. The profile has no review history we can cite, so ask for client references from owners who bought a business.
The limitation, plainly: the profile does not name opening balance sheets or purchase price allocation, so ask what is included and how the firm works with your CPA and attorney. It lists a $1 million revenue minimum, so a smaller business may fall outside it. A bookkeeping and fractional CFO firm does not replace legal counsel or a valuation professional.
6. Name Who Signs Off on the Opening Balance Sheet After an Acquisition
An opening balance sheet needs an owner. Decide who approves it, what documents they review and the date by which it is final. In many small deals that is the buyer plus an outside accountant, and sometimes the lender if there is a loan.
Set a date to revisit it once post-close adjustments are settled, and record what changed and why. A short note that explains each difference from the closing statement is worth more than a perfect spreadsheet with no explanation.
The limitation: sign-off confirms the numbers match the documents. It does not make the deal terms good or bad, and it does not replace a review of the agreement by counsel.
Frequently Asked Questions
What is an opening balance sheet after an acquisition?
It is the balance sheet your books start from on the closing date, showing the assets you acquired, the liabilities you assumed and the debt or equity you used to pay. It is built from the closing statement and purchase agreement and may change after post-close adjustments.
How is the purchase price allocated after an acquisition?
Generally the price is spread across the assets acquired, with what remains recorded as goodwill. The allocation often follows the purchase agreement or a schedule prepared afterward, and it affects depreciation and amortization. Ask your CPA how it applies to your deal and tax filings.
Should I record deferred revenue in my opening balances?
If customers paid the seller for work you now have to deliver, it is generally an obligation to record. Whether it transfers depends on how the deal is structured. Check the agreement and ask your accountant how to book it so later revenue is not overstated.
Who should prepare the opening balances?
Often your accountant, bookkeeper or a fractional CFO, working from the closing documents and with your attorney's input on the agreement. Ask any firm how it documents each opening figure, and what it needs from you and the seller.
Before your first close, collect the final purchase agreement, the closing statement, the debt documents and the seller's last trial balance, and mark every item that still has an adjustment pending. You can browse fractional CFOs on Sam's List and accountants, including the firm above, and ask each how it builds opening balances.
How We Picked This Firm
You should be able to check our work, so here is how this post was built.
The pool. The pool is the firm written up here, a vetted Sam's List member in our featured program. This is not a survey of every firm that supports buyers after an acquisition, and many Sam's List members and other firms not written up here could fit.
How it is organized. The six items are things to settle, not a ranking. System Six is the only firm written up, so there is no order of firms.
What review counts mean here. System Six has too few verified reviews on Sam's List for us to cite a count, so we describe it by its profile and do not rely on reviews. A count shows how many clients wrote something down. It does not measure technical quality.
What payment does and does not buy. Listing on Sam's List is free, and so is being named in this article. The firm written up here is a paying member of our featured program, which is why it gets a write-up. What payment does not buy is the language we use about a firm, its review count, or a promise that it fits you.
