A business buyer and an attorney sit at a desk reviewing documents as part of the due diligence process

In the due diligence process, you’ll review the ins and outs of the business you intend to buy. You’ll gather the data you need to assess its financial strength, verify the owner’s claims, and ensure that you fully understand the business as it stands today.

You’ll need a good accountant and business attorney for the due diligence process. Here’s why:

  • The accountant you select will help you work through the financials, spot discrepancies, and find red flags.
  • The attorney you choose will help you understand the documents you’ll be asked to sign to ensure confidentiality, make sense of how your purchase should be structured, and help you negotiate the terms of your deal.


You’ll start the due diligence process by signing a non-disclosure agreement (NDA) that the seller’s attorney creates. This document assures the seller that you won’t share any of the confidential information you learn about the business with undisclosed outside parties.

After receiving your signed NDA, you can access the business’s financials, founding documents, operations manuals, and HR information you need to form a complete assessment of the business. You’ll be given time to review this information, which could take as little as a few weeks or several months depending on the complexity of the business and the questions you have about its operations.


Which documents will I need for my due diligence assessment?

At a minimum, you should ask the seller for the following items:

  • Founding paperwork, including the business’s articles of organization or articles of incorporation
  • Valid permits and business licenses
  • Proof of relevant trademarks, copyrights, and patents
  • Insurance declarations
  • Real estate documents or lease information that spells out terms and transferability
  • Contracts, including lease and purchase agreements, distribution agreements, vendor contracts, subcontractor agreements, sales contracts, union contracts, employment agreements, and other contracts the business is bound to fulfill
  • Three to five years’ worth of financial information, which should include tax returns, balance sheets, profit-and-loss statements, sales records, debt disclosures, payroll information, and marketing costs, as well as a 30-, 60-, 90-, and greater-than-90-day breakdown of accounts receivable and accounts payable information
  • Organizational charts
  • HR policies and benefit plans
  • Inventory records and valuations
  • Furniture, fixtures, and equipment records and valuation
  • Information regarding closed and outstanding legal concerns
  • A certificate of good standing, which the seller can attain from the Secretary of State in the business’s home state


How do I make sense of this information?

You’ll want to read all of the items you receive in their entirety and share them with your accountant and attorney. Together, you’ll study the business’s financial, legal, operational, and HR strengths and weaknesses. Use this due diligence checklist for buying a business to assign key tasks.


Your accountant’s role in the due diligence checklist for buying a business

Your accountant will play a key role in assessing the financial health of the business. This pro will look for consistencies among accounts, assets, and liabilities; identify trends; and form projections about the business.

Your role in the due diligence checklist for buying a business

You’ll play an important role in the due diligence process, too, and your checklist items for buying a business include other equally important items. Of course, you’ll work with your accountant and attorney and ask the seller for the information your team needs to make its assessments. But you’ll also analyze other parts of the business that are key to its success. Here, you’ll look into its operations practices, customer information, employee structure, and competitive positioning. Let’s look at a short list of the tasks you’ll take on:


Closed bookStudy the organization’s procedures and protocols.
HelpEnsure that the facilities meet safety and health requirements.
BoardroomReview the business’s insurance coverages and make sure the current coverages are sufficient.


Open bookStudy the practices the business uses to attract customers.

InternetStudy search results and social media reviews of the business.

What are some of the red flags we might find during due diligence?

Problems can exist in every facet of a business. Some of these problems may be relatively insignificant and easy to overcome. Others, including hefty business debts, the need for expensive upgrades, quality issues, or issues with the brand or owner’s affiliation to it, may turn you off from the purchase altogether.

It’s also possible that you’ll find problems in the market that’ll make you shy away from the purchase. Problems like a diminishing market, rising costs of inputs, and strengthening competitors could fall into this category.


What happens after our assessment?

Through the due diligence process, you’ll learn a great deal about the business you intend to buy. This will help you decide whether you should proceed with the purchase.

Be sure that you don’t rush the process. Take the time you need to review each part of the business thoroughly. Verify every claim and find answers to your outstanding questions.

Based on what you find, you may want to revisit the purchase price you offered the seller in your letter of intent (LOI). It’s not uncommon for buyers to lower an offer price. Many do it to account for lower valuations in inventory, disagreements about add-backs, or the discovery of unforeseen issues. This article can help you work through the most important steps:


Talk to the seller about any changes you make to your offer price. Then, after agreeing to a final purchase value, ask your attorney to draft a formal purchase (sales) agreement. Check out this article, which explains this important document.
