Due diligence is the investigation and analysis performed before completing a business transaction. In business financing, due diligence happens on both sides — lenders investigate borrowers before approving loans, and savvy borrowers should investigate lenders before accepting financing.

Lender Due Diligence

When you apply for a loan, lenders conduct due diligence to assess risk:

  • Financial review: Analyzing tax returns, financial statements, and bank statements
  • Credit analysis: Checking personal and business credit reports
  • Business verification: Confirming your business exists and operates as stated
  • Collateral assessment: Evaluating assets pledged as security
  • Legal review: Checking for liens, judgments, or legal issues
  • Industry analysis: Evaluating risks specific to your industry
  • Management evaluation: Assessing the experience and capability of owners

Documentation Typically Requested

Be prepared to provide:

  • Personal and business tax returns (2-3 years)
  • Profit and loss statements and balance sheets
  • Bank statements (3-6 months)
  • Accounts receivable and payable aging
  • Business licenses and legal documents
  • Lease agreements
  • Existing debt schedule
  • Business plan (for larger or SBA loans)

Borrower Due Diligence

You should also conduct due diligence on potential lenders:

  • Total cost: Calculate the true APR, including all fees
  • Terms review: Understand payment frequency, prepayment penalties, and covenants
  • Reputation: Research the lender through reviews, BBB, and industry sources
  • Hidden clauses: Look for confession of judgment, blanket liens, or other concerning terms
  • Customer service: Assess responsiveness and professionalism during the application

Compare Multiple Offers

Always compare at least 2-3 financing offers. Lenders know informed borrowers shop around, and competition often leads to better terms.

Due Diligence for Business Acquisitions

If you are buying a business with loan proceeds, additional due diligence is required:

  • Verify seller's financial claims with independent records
  • Review customer and vendor contracts
  • Assess employee and payroll obligations
  • Check for pending litigation or claims
  • Evaluate equipment condition and value
  • Confirm intellectual property ownership

Timeline Expectations

Due diligence takes time:

  • Online lenders: 1-7 days for simplified underwriting
  • Bank term loans: 2-6 weeks for full due diligence
  • SBA loans: 30-90 days including SBA review
  • Acquisition financing: 60-120 days with business due diligence

Prepare your documents before starting the application process. Having organized, complete documentation speeds up due diligence and demonstrates professionalism to lenders.
