Getting ready to sell your small business in California? Due diligence is coming, whether you're ready or not. This intensive investigation process can make or break your deal. At Decipher Your Value, we've seen many business owners scramble at the last minute to pull together documents that should have been organized long before the business was up for sale.
Due diligence is when potential buyers dig deep into every aspect of your business to verify what you've told them is true. Think of it as a financial colonoscopy: uncomfortable, but necessary. The good news? With proper preparation, you can turn this scrutiny into a competitive advantage.
Financial Documentation: Your Foundation
The financial review is where most deals live or die. Buyers want to see three to five years of clean, audited financial statements. If you've been doing your own books in QuickBooks, now's the time to get professional help.
Essential Financial Documents
Audited financial statements (3-5 years)
Monthly financial statements (current year)
Tax returns (business and personal if guarantees exist)
Bank statements and reconciliations
Accounts receivable aging reports
Accounts payable schedules
Inventory reports with costing methods
Cash flow statements and projections
Pro tip: According to the SBA, businesses with clean, organized financials sell for 15-20% higher multiples than those with messy books.
Red Flags to Address Early
Personal expenses running through the business
Related party transactions without proper documentation
Inconsistencies between tax returns and financial statements
Large one-time adjustments or unusual entries
Legal and Compliance Documentation
California has some of the strictest business regulations in the country. Your legal house needs to be in perfect order for business sale preparation.
Corporate Structure Documents
Articles of incorporation or organization
Bylaws or operating agreements
Stock certificates and cap table
Board resolutions and meeting minutes
Shareholder or member agreements
Contracts and Agreements
Customer contracts and service agreements
Supplier and vendor contracts
Employment agreements and offer letters
Non-disclosure and non-compete agreements
Lease agreements for facilities and equipment
Insurance policies and claims history
Don't forget about intellectual property. If your business has trademarks, patents, or copyrights, make sure they're properly registered and assigned to the company, not to you personally.
Operational Records That Tell Your Story
Buyers want to understand how your business runs day-to-day. This operational due diligence helps them assess whether the business can survive without you.
Key Operational Documents
Standard operating procedures (SOPs)
Quality control and safety manuals
Vendor and supplier lists with contact information
Customer lists and relationship maps
Organizational chart with job descriptions
Key performance indicators (KPIs) and metrics
Equipment lists and maintenance records
According to SCORE, businesses with documented processes sell 25% faster than those relying on tribal knowledge.
Technology and Digital Assets Assessment
In today's digital world, your technology infrastructure is a critical asset—or liability.
Technology Documentation Needed
IT systems inventory and licenses
Software subscriptions and contracts
Website ownership and hosting details
Social media accounts and passwords
Customer databases and CRM systems
Cybersecurity policies and incident reports
Backup and disaster recovery procedures
Make sure all digital assets are owned by the company, not registered under personal accounts. Buyers hate discovering the company website is registered to "JohnSmith@gmail.com."
Human Resources Documentation
Your team is often your biggest asset. Proper HR documentation proves you've built a business that can operate independently.
HR Documents to Organize
Employee handbook and policies
Organizational chart and reporting structure
Compensation and benefits summaries
Performance reviews and disciplinary actions
Training programs and certifications
Workers' compensation claims history
Equal employment opportunity compliance records
California's employment laws are complex. According to the California Department of Industrial Relations, proper employment documentation is crucial for avoiding post-sale liabilities.

Tax Documentation Required
Federal and state tax returns (3-5 years)
Sales tax returns and permits
Payroll tax records and filings
Property tax assessments
Any tax audits or correspondence with agencies
1099s and other third-party reporting
Regulatory Compliance Records

Industry-specific regulatory filings
The California Secretary of State maintains records of business entities, so make sure your corporate status is current and in good standing.
Customer and Revenue Analysis
Buyers want to understand your revenue quality and customer relationships.
Customer Documentation
Customer contracts with terms and renewal dates
Customer concentration analysis
Pricing policies and discount structures
Sales pipeline and forecasting methods
Customer satisfaction surveys or testimonials
Account receivable aging and collection policies
If more than 20% of your revenue comes from a single customer, be prepared to explain the relationship and provide comfort about its stability.
