Due Diligence Guide for Acquiring a Janitorial Supply Distributor

Know exactly what to verify before buying a jan-san distribution business — from customer concentration and supplier exclusivity to inventory quality and driver retention.

Find Janitorial Supply Distributor Acquisition Targets

Acquiring a janitorial supply distributor in the $1M–$5M revenue range requires scrutiny of recurring commercial accounts, supplier rebate structures, route-based logistics, and inventory health. Deals typically close at 3–5x EBITDA using SBA 7(a) financing with a working capital peg tied to 90-day trailing inventory and receivables.

Janitorial Supply Distributor Due Diligence Phases

01

Phase 1: Commercial & Financial Validation

Verify normalized EBITDA, customer revenue concentration, and gross margin by product category before advancing to LOI or deeper operational review.

Normalize EBITDA with Owner Add-Backscritical

Request 3 years of tax returns and P&Ls. Identify personal vehicle expenses, owner compensation above market, and non-recurring costs to produce a clean EBITDA schedule.

Customer Concentration Analysiscritical

Obtain revenue by account for trailing 12 months. Flag any single account exceeding 20% of revenue and assess contract status, tenure, and renewal terms.

Gross Margin by Product Categoryimportant

Segment margins across commodity consumables, private-label products, and equipment. Identify where margin compression from Grainger or Amazon Business is most acute.

02

Phase 2: Supplier, Inventory & Operations Review

Assess the transferability of supplier agreements, inventory quality, and operational infrastructure including delivery routes and warehouse management systems.

Supplier Agreement Transferabilitycritical

Review all distribution agreements for change-of-control clauses, exclusivity provisions, and rebate structures. Confirm top vendors will honor terms post-acquisition.

Inventory Audit and Obsolescence Reviewimportant

Conduct a physical count and calculate SKU-level turnover rates. Identify slow-moving or obsolete stock inflating working capital and negotiate exclusion or write-down at close.

Route Density and Delivery Infrastructureimportant

Evaluate delivery route efficiency, vehicle fleet condition, and whether same-day or next-day delivery capabilities supporting customer retention are maintainable post-close.

03

Phase 3: People, Legal & Deal Structure

Confirm key-person risk is manageable, verify legal and licensing compliance, and finalize working capital peg and deal structure before closing.

Key-Person and Sales Staff Retention Riskcritical

Determine if the owner manages primary account relationships. Assess whether a sales rep or operations manager can assume responsibility and negotiate seller transition and non-compete terms.

Licenses, Leases, and Vehicle Registrationsimportant

Confirm all business licenses, commercial leases, and fleet registrations are current and transferable under an asset purchase structure without landlord or agency re-approval delays.

Working Capital Peg and Earnout Structurestandard

Set working capital target using 90-day trailing inventory and receivables average. Consider a 10–20% earnout tied to 12-month post-close retention of top commercial accounts.

04

Phase 4: SBA Financing and Deal Structure Validation

Verify the Janitorial Supply Distributor acquisition qualifies for SBA financing, the purchase price is supportable by the verified cash flow, and the deal structure protects the buyer's downside.

SBA Eligibility Confirmationcritical

Confirm the Janitorial Supply Distributor meets SBA 7(a) eligibility requirements: the business is for-profit, U.S.-based, within SBA size standards, and the buyer meets personal financial requirements. Some industries have specific SBA restrictions — verify before LOI.

Normalized EBITDA vs. SBA Debt Service Coveragecritical

Model verified normalized EBITDA against projected SBA loan payments at current rates. A $1M SBA 7(a) loan at 10.5% over 10 years costs approximately $13,000/month. The Janitorial Supply Distributor must generate at least 1.25x debt service coverage after a market-rate manager salary to pass underwriting.

Seller Note and Earnout Structure Reviewimportant

Confirm the seller note is properly subordinated to the SBA loan and goes on 24-month standby as required by SBA rules. If an earnout is included, define exact measurement metrics, time period, and dispute resolution process before signing the purchase agreement.

Janitorial Supply Distributor-Specific Due Diligence Items

  • Validate supplier rebate program eligibility post-close — many rebate tiers reset with ownership change and can materially reduce effective gross margins in year one.
  • Review auto-replenishment program contracts with commercial accounts, as these represent the highest-retention, most predictable revenue in the business.
  • Assess pricing agreements with school districts, healthcare facilities, or government accounts for contract duration, re-bid risk, and pricing escalation provisions.
  • Confirm private-label product sourcing agreements are assignable and that labeling rights transfer with the business under the asset purchase agreement.
  • Benchmark driver and warehouse compensation against regional logistics labor rates to identify post-close payroll risk from wage inflation or staffing gaps.
  • Verify that the purchase price divided by verified normalized EBITDA produces a multiple consistent with current market comparables for Janitorial Supply Distributor transactions — overpaying by 0.5x–1.0x EBITDA is the most common buyer error in this sector.
  • Confirm the lease terms are assignable to the buyer with the landlord's written consent, and that the remaining lease term extends at least through the SBA loan term — lenders require this before funding.
  • Request copies of all material vendor contracts, supplier agreements, and service relationships — confirm which are transferable, which require novation, and which may terminate on change of ownership.

Standard Document Request List

Before signing a Letter of Intent, request these documents from the seller. Missing or incomplete items are a red flag — not a reason to proceed without them.

  • 3 years of business tax returns (Schedule C or Form 1120)
  • Last 3 years profit & loss statements (monthly detail)
  • Current balance sheet and accounts receivable aging
  • Customer/client list with revenue by account (anonymized)
  • All active contracts, subscriptions, and recurring agreements
  • Equipment list with condition and estimated replacement cost
  • Employee roster with tenure, title, and compensation
  • Any pending or threatened litigation or regulatory complaints
  • Owner compensation and discretionary expense add-backs
  • Year-to-date financials vs. prior year same period

Frequently Asked Questions

What EBITDA multiple should I expect to pay for a janitorial supply distributor?

Expect 3–5x EBITDA. Businesses with diversified accounts, exclusive supplier agreements, and gross margins above 28% command the higher end. Heavy customer concentration or owner-dependent sales compress multiples.

Can I use an SBA loan to acquire a jan-san distribution business?

Yes. Most deals in the $1M–$5M revenue range are SBA 7(a) eligible. A typical structure includes 10–15% buyer equity, an SBA loan, and a 5–10% seller note held for two years post-close.

How do I evaluate whether supplier relationships will survive a change of ownership?

Request copies of all distribution agreements and look for change-of-control clauses. Contact top vendors directly during due diligence to confirm willingness to assign agreements and maintain rebate tiers.

What is the biggest risk in acquiring a janitorial supply distributor?

Customer concentration tied to the owner's personal relationships is the most common value destroyer. Verify that at least two staff members hold active relationships with top accounts before closing.
