What documents do I need to prepare to sell my business?

Published August 15, 2026

You typically need 3–5 years of historical financial statements, complete corporate records, current tax filings, material contracts, asset documentation, and regulatory compliance certificates. Most advisors recommend beginning document preparation 6–12 months before listing to address gaps and correct issues.

Core Financial Documents

Buyers commonly require 3–5 years of balance sheets, income statements, and cash flow statements. For businesses generating over $1 million in annual revenue, reviewed or audited financial statements are typically expected.

You must also provide:

  • Aging accounts receivable and accounts payable reports as of the most recent month-end
  • Asset lists with current book values and depreciation schedules for asset-based valuations
  • Customer concentration data showing the percentage of revenue from your top 5–10 customers

Legal and Corporate Records

Canadian business sales require current corporate documentation. Articles of incorporation and bylaws are mandatory. Minute books documenting all shareholder and director meetings and resolutions must be current and complete. A current corporate registry search showing ownership structure is required in all provinces.

Franchise agreements and franchisor consent letters are required when selling a franchised business under provincial franchise disclosure legislation.

Operations and Asset Documentation

Material contracts including supplier agreements, customer contracts, leases, and employment agreements must be disclosed during due diligence. You must compile intellectual property documentation including trademark registrations, patents, copyrights, and domain ownership records.

Operations documentation typically includes:

  • Organizational charts showing reporting structure and key personnel roles
  • Insurance policies including general liability, property, key person, and professional liability coverage with amounts and expiry dates
  • Trade licenses, permits, and regulatory compliance certificates specific to your business vertical — these must be documented and transferable

Tax and Compliance Records

Buyers and their lenders typically request 3–5 years of corporate tax returns including T2 returns and all schedules. GST/HST filings and remittance records are expected to be current with no outstanding balances or penalties. Payroll records including T4 summaries, source deductions, and workplace safety insurance compliance are typically required as part of a complete financial package.

Customer and Revenue Documentation

Buyers need visibility into revenue stability and customer relationships. Customer concentration analysis showing what percentage of revenue comes from your largest customers is a standard due diligence request. This helps buyers assess risk if one or more major customers were to leave after the transaction.

When to Prepare These Documents

Begin document preparation 6–12 months before listing to identify missing records, correct discrepancies, bring compliance current, and address issues that could derail negotiations.

For businesses with real property or manufacturing operations, environmental site assessments or Phase I ESAs are commonly required. Real property documentation including title searches, surveys, and zoning compliance certificates must be current.
