How to Prepare Your Books for an Acquisition

Acquisitions move fast once they start. A buyer expresses interest, an LOI gets signed, and suddenly you have 30 to 60 days to produce three years of clean financials, a data room full of organized documentation, and answers to questions you've never been asked before.

Most small businesses aren't ready for that. And the ones that aren't ready either lose the deal, leave money on the table, or spend a frantic few weeks trying to clean up years of accounting shortcuts.

Here's what acquirers actually look at — and how to be ready before they ask.

When a buyer or their accountants dig into your financials, they're trying to answer a few core questions:

• Is the revenue real and recurring?
• Are the margins sustainable?
• Are there any hidden liabilities or off-balance-sheet obligations?
• Can this business run without the current owner?

Every document request, every question, every line item they scrutinize is in service of those four questions. Understanding that makes the process less overwhelming.

Buyers want to see three years of P&L, ideally reviewed or compiled by a CPA. They'll look for revenue trends, margin consistency, and any unusual spikes or drops that need explanation.

One-time items — a large non-recurring expense, a lawsuit settlement, a one-time customer — should be clearly identified and explained. Buyers will adjust for them in their valuation model, but only if they understand what they are.

The balance sheet tells buyers what they're actually buying. They'll scrutinize accounts receivable (how old is it? is any of it uncollectible?), inventory (is it valued correctly?), and any debt or obligations that will transfer with the business.

Unreconciled accounts are a red flag. If your bank accounts haven't been reconciled in months — or years — that's the first thing to fix.

Cash flow tells the story that the P&L sometimes hides. A business can look profitable on paper while hemorrhaging cash. Buyers know this, and they'll build their own cash flow model. The cleaner your records, the more confidence they'll have in the numbers.

A data room is a secure, organized repository of everything a buyer needs to complete due diligence. For a small business acquisition, a typical data room includes:

• Financial statements: Three years of P&L, balance sheet, and cash flow
• Tax returns: Three years of business tax returns
• Bank statements: Matching the financial statements, reconciled
• Customer contracts: Especially any recurring revenue agreements
• Vendor contracts: Key supplier relationships and terms
• Employee information: Org chart, compensation, any employment agreements
• Legal documents: Entity formation, any litigation history, IP ownership
• Leases: Real estate, equipment, vehicles

The goal is to answer questions before they're asked. A well-organized data room signals that the business is well-run — which directly affects buyer confidence and valuation.

This is the most common issue, and it's fixable — but it takes time. I worked with a business that hadn't reconciled a bank statement in three years when an acquirer came calling. We got it done in a week, but it was an intense week that could have been avoided entirely.

If your books aren't reconciled monthly, start now. Don't wait for a buyer to find it.

Personal expenses running through the business are common in small businesses. Buyers expect some of it, but they need to understand the full picture. Every personal expense needs to be identified, quantified, and added back in the quality of earnings analysis.

The more clearly this is documented, the less friction it creates.

If 40% of your revenue comes from one customer, buyers will discount the valuation — or walk away. This isn't something you can fix in 30 days, but it's worth knowing about years before you sell.

Gaps in documentation — missing contracts, undocumented verbal agreements, inconsistent record-keeping — create uncertainty. Uncertainty kills deals or reduces valuations. Consistent, organized records do the opposite.

The best time to prepare for an acquisition is two to three years before you plan to sell. That gives you time to:

1. Clean up the books: Reconcile everything, fix any classification errors, and establish consistent accounting practices going forward.
2. Build a track record: Three years of clean, consistent financials is the gold standard. Start building that track record now.
3. Reduce owner dependence: Document processes, build a management team, and make sure the business can run without you in the room.
4. Identify and address red flags: Revenue concentration, aging receivables, deferred maintenance — find them yourself before a buyer does.

If a buyer comes calling before you're ready, don't panic. A good financial partner can accelerate the cleanup significantly. But the businesses that get the best outcomes are the ones that were ready before the conversation started.
