How do you finance the purchase of a building supply company?

A retailer that is also a lender to its customers

A homeowner pays at the counter. A framing contractor, a remodeler or a roofer usually does not: most of a building supply dealer's sales go out on trade accounts, delivered to a job site and paid for on terms. That makes the business look more like a distributor than a store. It carries a large receivables balance, it takes credit risk on small contractors, and its cash is tied up in inventory and receivables in a way that a lender has to finance separately from the purchase price.

That is the first thing a lender works out when it reads a building supply file: how the dealer earns, and on what terms. The SBA lending data for building material dealers shows the shape of the trade. Acquisitions are roughly twice as large a share of approvals as across the SBA program, acquisition loans run far above the industry's typical loan, and SBA 504 is used often, because many dealers own a sizeable yard. Buyers are active here, and lenders know the business.

Earnings through a cycle, not at a peak

Wood is a commodity, and its price can swing sharply within a couple of years. When prices spike, a dealer's sales rise without selling a single extra board, and its margin often widens too, because inventory bought at the old price is sold at the new one. When prices fall, the opposite happens: sales shrink and the yard sells stock for less than it paid. A buyer looking at a strong recent year needs to know how much of it was the market.

Lenders look at several years of results and ask what gross profit in dollars looks like at ordinary prices. A simple case: a yard earned 900 in the year lumber prices peaked and around 600 in the years on either side. A lender sizing the loan will lean toward something nearer the 600, and a price built on the 900 will leave a gap that the buyer has to fill with equity or a seller note. Many dealers also account for inventory in ways that move taxable income when prices change, so the tax returns and the internal statements may tell different stories, and a lender will want them reconciled.

The cycle matters more from 1 October 2026. SBA requires debt service coverage of at least 1.15x, and from that date a change of ownership must show 1.25x on historical results, so the dealer's actual past earnings have to carry the new debt. From the same date, financial due diligence is required on every change of ownership, and a quality of earnings report on acquisitions of $3 million or more excluding real estate. For a dealer, that review will spend real time on inventory: how it is counted and valued, and whether a price move has flattered the margin.

Lenders also ask what drives demand in the trade area. A yard selling mostly to remodelers and repair contractors tends to hold up better in a construction slowdown than one framing subdivisions for a handful of builders.

Receivables, inventory and the working capital line

The acquisition loan pays the seller. It does not fund the next month of contractor receivables and restocking. A building supply dealer needs a revolving line of credit, and lenders usually expect it to be in place at closing, sized to the dealer's working capital through the busy building season. How lenders set that line is covered in how a borrowing base works and using a revolver in an acquisition.

Contractor receivables are good collateral when they are collected. Lenders will ask how the dealer sets credit limits, how old its receivables run, and what its bad debts have been in a slow year. A dealer that sends preliminary lien notices on job accounts, as the law in many states allows, has a second way to get paid when a contractor does not, and lenders like to see that discipline. See what lenders look for in an AR aging.

The purchase agreement has to say how much working capital comes with the business. Most deals are priced cash-free and debt-free with a working capital target, so the seller delivers a normal level of receivables and inventory, and the buyer's line funds growth from there. A target set too low hands the buyer a business that needs cash on day one; see the working capital peg.

Agree the line of credit with the acquisition loan, not after it. A yard that closes without one is short of cash by its first busy season.

What transfers to a new owner

Much of a dealer's value sits in relationships and agreements that belong to the seller, and a lender will want to know which of them the buyer actually gets.

• Contractor relationships. Pro customers buy from people: the outside salespeople, the yard manager, the counter staff who know their jobs. Lenders ask who holds the largest accounts and whether those people are staying. Retention agreements for key salespeople are common, and lenders read them as a sign the buyer has thought about it.
• Manufacturer dealer agreements. Window, door, roofing and millwork lines are often sold under dealer agreements that need the manufacturer's consent to a change of owner. Losing a major line can move margin. See change-of-control consents.
• Buying group membership. Many independent dealers buy through a cooperative or buying group that pays year-end rebates. Lenders want those rebates shown consistently in the figures and confirmation that membership continues under the buyer.
• The yard. If the seller owns the property and will lease it to the buyer, the lease needs a term, with options, at least as long as the loan, and a market rent. If the buyer is purchasing it, lenders will commission an appraisal and an environmental review, because yards can have fuel tanks, treated-wood storage and years of truck traffic. See acquisitions that include real estate.
• The seller. In a complete change of ownership financed by SBA, the seller may not stay on as an owner, officer or employee, but may consult for up to 12 months, and up to 24 months under SOP 50 10 8.1 from 1 October 2026. In a business where the seller has known the builders for decades, that transition period is worth planning carefully; see SBA seller transition.

How the deal is usually structured

The collateral makes this business more financeable than many service companies with the same earnings, and conventional asset-based lenders know the trade. What limits the loan is usually coverage: from 1 October 2026, change-of-ownership 7(a) loans amortize over no more than 10 years except the real estate share, so the payment on the goodwill is heavy, and the historical earnings have to cover it.

Two SBA rules shape the negotiation. SBA prohibits an earnout to the seller in a change of ownership it finances, so a price gap over a boom year has to be closed with a lower price or a seller note, not a payment tied to future results. And where the amount financed, less appraised real estate and equipment, exceeds $250,000, SBA requires an independent business valuation, and the loan for the purchase cannot exceed it; see the valuation requirement. Deals above the SBA ceiling are covered in acquisitions above the SBA limit.

The risks lenders price

• The building cycle. A slowdown in new construction hits volume and receivables at the same time.
• Builder concentration. A yard where a few production builders take a large share of sales carries their risk. See customer concentration.
• Bad debt. Small contractors fail in downturns, and a dealer with loose credit limits finds out all at once.
• Big-box and direct competition. Home centers compete for the do-it-yourself and small-contractor trade; lenders ask what keeps pros buying from this yard.
• Inventory quality. Dead stock, damaged material and special orders nobody collected sit on the balance sheet at cost and sell for much less.
• Fleet and yard capital needs. Aging trucks and forklifts need replacing; lenders treat that spending as a cost of staying in business. See maintenance capex.

What goes in the file

Start with the standard SBA acquisition documents in what lenders need to finance an acquisition: two to three years of business tax returns, the P&L and balance sheet, a year-to-date P&L, the debt schedule, personal returns and a personal financial statement for each owner of 20% or more, the signed letter of intent and the target's latest full year of figures, never an older year. The line of credit adds its own list. For a building supply dealer, lenders also want:

• An AR aging by customer, with days outstanding, and an AP aging.
• An inventory report by category, with the age of slow-moving stock.
• Sales and gross margin by product line and by customer, including the largest contractor accounts.
• Bad-debt write-offs by year.
• Dealer agreements and buying group terms, with rebate history.
• A fleet and equipment list with ages, and the lease or property details for the yard.
