The Due Diligence Checklist: What Buyers Will Ask For When You Sell Your Massachusetts Business

You've found a buyer. The letter of intent is signed. You're feeling good — maybe even relieved. Then your phone pings with an email containing a 47-item document request list, and your stomach drops. This is due diligence, and it's where deals go to die if you're not prepared. Understanding the due diligence checklist — what buyers will ask for when you sell your Massachusetts business — is the single most important thing you can do to protect your deal timeline, your valuation, and your sanity.

Due diligence isn't a formality. It's the buyer's opportunity to verify every claim you've made, stress-test your financials, and find reasons to renegotiate the price downward. The owners who navigate it smoothly are the ones who started preparing 12 to 18 months before going to market.

The Core Due Diligence Checklist: What Every Buyer Requests

While every deal is different, the due diligence request list for a $1M to $10M business acquisition in Massachusetts follows a remarkably consistent pattern. Here's what you should expect to produce:

• Three to five years of tax returns — federal, state, and any entity-level Massachusetts returns
• Profit and loss statements and balance sheets — monthly, for at least three years
• Accounts receivable and accounts payable aging reports — current and trailing 12 months
• Customer concentration data — revenue breakdown by client, with contract terms
• Employee roster and compensation details — including benefits, non-competes, and key-person dependencies
• Lease agreements — commercial real estate, equipment, vehicles
• Licenses and permits — especially Massachusetts-specific ones (contractor licenses, liquor licenses, health permits)
• Intellectual property documentation — trademarks, patents, proprietary software, domain registrations
• Pending or historical litigation — including any Massachusetts Attorney General inquiries or regulatory actions
• Insurance policies — general liability, professional liability, workers' comp, key-person life
• Vendor and supplier agreements — particularly any with exclusivity clauses or volume commitments

That's not the full list. It's a starting point. Sophisticated buyers — especially private equity groups actively acquiring in the Route 128 corridor and Greater Boston — will go deeper. They'll want to understand your tech stack, your Google reviews, your employee turnover rate, and whether your QuickBooks file matches your tax returns.

Massachusetts-Specific Due Diligence Issues That Catch Sellers Off Guard

Selling a business in Massachusetts comes with state-specific wrinkles that sellers in other markets don't face. Here are the ones that trip up owners most often:

The Massachusetts Paid Family and Medical Leave Act (PFML). Buyers will verify you're compliant. If you've been misclassifying workers as 1099 contractors to avoid PFML contributions, that's a liability the buyer inherits — and they'll either walk or demand a price reduction.

Non-compete enforceability. Since the Massachusetts Noncompetition Agreement Act took effect in 2018, non-competes here have specific enforceability requirements — garden leave provisions, 12-month maximum duration, and more. If your key employees signed non-competes before 2018 that don't comply, a buyer's attorney will flag that immediately. It changes the risk profile of the deal.

Sales tax nexus. If you sell products or SaaS into other states from your Waltham or Newton office, buyers will want to confirm you've been collecting and remitting sales tax properly. Uncollected sales tax is a hidden liability that can amount to tens of thousands of dollars.

Environmental compliance. For businesses in older commercial spaces — common across Quincy, Worcester, and the inner suburbs — Phase I environmental assessments may be required, especially if the real estate is part of the transaction.

The Financial Documents That Make or Break Your Due Diligence Checklist

Here's the hard truth: roughly 30% of signed LOIs in the lower middle market never make it to closing. The number one reason? Financial discrepancies discovered during due diligence.

The buyer's CPA will compare your tax returns against your P&L statements against your bank statements. If those three sources don't tell the same story, you have a problem. It doesn't mean you did anything wrong — it often means your bookkeeping was sloppy, or your accountant made adjustments you weren't aware of.

This is exactly why we perform forensic financial recasting for every client at Nova Exit Partners before they go to market. We rebuild your financials from scratch, identify and document every owner add-back, and create a clean adjusted EBITDA presentation that can withstand buyer scrutiny. A business generating $400K in adjusted EBITDA at a 3.5x multiple is a $1.4M deal. But if a buyer's due diligence knocks that EBITDA down to $320K because of undocumented add-backs, you just lost $280,000. That's the cost of being unprepared.

Consider a real scenario: a professional services firm owner in Cambridge assumed his wife's $85,000 salary was an obvious add-back because she only worked part-time. But he had no documentation showing what a market-rate replacement would cost. The buyer's team argued the add-back should be $40,000, not $85,000. That $45,000 difference, multiplied by the deal multiple, moved the purchase price by over $150,000.

How to Prepare for Due Diligence 12 Months Before You Sell

If you're a business owner in Greater Boston thinking about selling in the next one to three years, start your due diligence preparation now. Here's the priority list:

• Clean up your books. Hire a bookkeeper or upgrade your current one. Make sure your P&L, balance sheet, and bank statements reconcile monthly.
• Document everything. If it's not written down, it doesn't exist in due diligence. Customer contracts, vendor agreements, employee handbooks, SOPs — get them in order.
• Resolve outstanding issues. That lingering sales tax question? The employee misclassification you've been meaning to fix? The unsigned lease renewal? Handle it now, when it's cheap to fix — not during a deal, when it's expensive.
• Separate personal from business. Stop running personal expenses through the company. Yes, the add-backs are legitimate, but every one creates friction in due diligence.
• Get a pre-sale assessment. Work with an advisor who will look at your business through a buyer's eyes and tell you what needs to be fixed before you go to market.

The owners who close at full asking price aren't necessarily running better businesses. They're running better-documented businesses.

Don't Let Due Diligence Derail Your Exit

Selling your Massachusetts business is likely the largest financial transaction of your life. The due diligence phase is where preparation meets reality — and where underprepared sellers leave hundreds of thousands of dollars on the table through renegotiations, delays, and failed deals.

At Nova Exit Partners, we've been on both sides of this process. Erik Kretschmar has sold four of his own businesses and knows exactly what buyers look for — because he's been the one looking. We help Boston-area business owners build a due diligence package that's airtight before the first buyer ever sees it.

If you're even beginning to think about selling, the best time to start preparing is now. Get your free business valuation and find out where you stand — and what you need to fix before you go to market.
