Buyer Due Diligence Checklist for Flooring Installation Businesses

Request 3 years of tax returns and reconcile to monthly P&L statements and bank deposits.

Owners sometimes underreport revenue or mix personal expenses into business costs, distorting SDE calculations.

Red flag: Tax returns show significantly lower revenue than P&L statements with no clear explanation.

Obtain a job costing report broken down by project type: residential, commercial, and multi-family.

Gross margins vary widely by segment; blended averages can hide unprofitable project categories.

Red flag: No job costing system exists and margins are estimated rather than tracked per project.

Review accounts receivable aging to identify slow-paying or delinquent commercial clients.

Commercial flooring clients often pay on 30–60 day terms; aged receivables signal collection problems.

Red flag: More than 20% of receivables are 90+ days past due with no documented collection effort.

Analyze material cost trends and confirm supplier pricing agreements are documented and transferable.

Rising material costs on fixed-price contracts compress margins; locked pricing protects post-close profitability.

Red flag: Gross margins have declined more than 5 points over 3 years with no explanation from the seller.

Map revenue by customer for each of the last 3 years and calculate top-client concentration percentages.

A single client exceeding 20% of revenue is a structural risk that directly impacts valuation and deal terms.

Red flag: One general contractor or property management company accounts for more than 30% of annual revenue.

Review all active contracts, preferred vendor agreements, and signed project proposals in the pipeline.

Backlog and contracted work determine how much revenue transfers to the buyer at close.

Red flag: Most revenue is verbal or handshake-based with no written contracts or preferred vendor documentation.

Interview the seller about how commercial relationships were established and who holds the key contact.

If the owner is the sole relationship holder, accounts may not survive the transition to new ownership.

Red flag: All major commercial clients call the owner directly and have no relationship with any other staff member.

Review Google reviews, Houzz profiles, and BBB standing to assess brand reputation in the local market.

Reputation drives referral volume; a strong review profile reduces post-acquisition marketing costs.

Red flag: Consistent negative reviews citing installation quality or warranty disputes with no documented resolution.

Obtain a full list of all 1099 subcontractors used in the last 3 years with payment amounts and roles.

Subcontractors classified incorrectly as independent contractors create significant IRS and state labor liability.

Red flag: High-volume subcontractors work exclusively for this business, follow its schedule, and use its equipment.

Assess whether key crew leads and project managers have agreed to continue post-acquisition.

Experienced installers are difficult to replace; losing key crews can derail projects and damage client relationships.

Red flag: The owner confirms that most subcontractors work for the business only because of their personal relationship.

Review workers' compensation insurance certificates for all subcontractors performing installation work.

Uninsured subcontractors expose the acquiring entity to on-site injury liability from day one of ownership.

Red flag: Multiple subcontractors lack current workers' comp coverage and the seller has not required certificates.

Confirm whether any employees are currently subject to non-solicitation or non-compete agreements.

Protecting key talent post-acquisition requires enforceable agreements; absent protections increase turnover risk.

Red flag: No employment agreements exist and the owner admits staff could freely work for competitors after the sale.

Verify all state and local contractor licenses are current, in good standing, and transferable to a new owner.

Some states require a new license application under the buyer's name, creating a gap in bidding eligibility.

Red flag: The primary license is held personally by the owner and cannot be transferred to a new legal entity.

Confirm general liability and commercial auto insurance policies are active with adequate coverage limits.

Flooring contractors face property damage liability; coverage gaps create uninsured exposure at close.

Red flag: Coverage lapses appear in the insurance history or current limits fall below industry standard minimums.

Review any outstanding warranty claims, customer disputes, or litigation involving installation defects.

Unresolved warranty obligations transfer to the buyer and can represent material undisclosed liabilities.

Red flag: Multiple unresolved warranty claims exist for hardwood cupping, tile cracking, or adhesive failures.

Confirm certified installer status with major flooring brands such as Shaw, Mohawk, or Armstrong.

Brand certifications unlock referral pipelines and manufacturer warranties that support premium pricing.

Red flag: Certifications are registered under the owner's personal credentials and lapse upon ownership transfer.

Request an organizational chart showing crew leads, project managers, and administrative roles.

A documented structure signals the business can operate independently; its absence signals key-man risk.

Red flag: The owner is the sole estimator, primary client contact, and field supervisor with no documented backup.

Evaluate the estimating and job scheduling system — software, templates, or manual processes used.

Standardized estimating protects margins; manual owner-driven quoting does not transfer reliably.

Red flag: All estimates are done from memory or informal spreadsheets with no repeatable pricing methodology.

Assess inventory management practices and confirm physical inventory matches the balance sheet value.

Flooring material inventory is often overstated; excess or obsolete stock reduces working capital quality.

Red flag: Inventory records are informal, physical counts have not been done recently, and slow-moving stock is aged.

Review vehicle and equipment schedules to confirm condition, ownership status, and replacement needs.

Trucks, vans, and installation equipment are core operating assets; deferred maintenance reduces net value.

Red flag: Multiple vehicles are in poor condition or are personally owned by the seller and not included in the deal.
