The Working Capital Peg in a Business Acquisition: What It Is and Why It Matters at Closing

The short version

• Two buyers can agree on the exact same purchase price and still close $25,000 apart, because of working capital nobody negotiated.
• Working capital is the cash and near-cash the business needs to run, and in most deals it is delivered as part of the price, not on top of it.
• Set the target too low and you fund the first quarter out of your own pocket, on top of debt service.
• Below: what the peg is, how it settles at the table, and where it quietly costs the buyer cash.

Two buyers can sign at the same purchase price and still walk out of the closing tens of thousands of dollars apart. The reason is working capital, and most first-time buyers never put it on the negotiating table.

Working capital small business acquisition is the term that decides how much cash is actually in the business the morning after you own it. It is a transfer hidden inside the price, not a line item bolted on beside it.

A buyer who treats it as a back-office detail the lawyers will settle is the buyer who funds the first ninety days out of pocket. Get the number wrong and you are servicing acquisition debt with one hand while floating payroll and payables with the other.

This article walks what the working-capital peg is, how the adjustment settles at closing, and what it costs when it is set too low.

What working capital is in an acquisition

Working capital in a business acquisition is the cash and near-cash assets the business needs to operate day to day, minus its short-term obligations. It is current assets such as receivables and inventory, less current liabilities such as payables.

In most deals the seller delivers a normal level of it as part of the purchase price. The business can then run from day one without the buyer injecting more cash.

That last point is where buyers get hurt. The number is not a side agreement; it is part of what you are buying.

Working capital lives on the balance sheet, which is why reading the P&L alone will never show it to you. A profitable business can hand over an empty checking account and a stack of bills if nobody negotiated the level delivered.

The cleanest way to think about it: profit is what the business earned, working capital is the fuel left in the tank. This is the same gap between profit on paper and cash actually in the business that decides whether you can make payroll in week two.

Why the business needs the fuel at all is the cash conversion cycle. The company pays for labor and materials before customers pay their invoices, so it must always hold enough cash to fund that gap.

Working capital is the size of that gap, sitting on the balance sheet. Buy the business with the tank empty and you fund the gap yourself, starting the morning after close.

Why the peg is a negotiation, not a formula

The working-capital peg is the target level the seller agrees to deliver at close. It is usually set from a trailing twelve-month average of the business's normal working capital.

The formula looks objective. The inputs are not.

What the peg really decides is who funds the first quarter. It is a risk allocation dressed as an accounting line, and the dollars move in real life regardless of how neutral the spreadsheet looks.

Set it right and the business carries its own first quarter. Set it low and you have agreed, without noticing, to finance the seller's last quarter out of your own pocket.

Buyer and seller pull the peg in opposite directions, because every dollar of the target is a dollar of real money:

• The seller wants the peg low. A lower target means they keep more cash and collect more receivables on the way out.
• The buyer wants the peg adequate. A peg set to a thin month leaves the business undercapitalized the day you take over.
• Both argue over "normal." Seasonality, a recent slow quarter, or one large unpaid invoice can swing the trailing average by tens of thousands of dollars.

This is why the peg belongs in the same conversation as the rest of your deal terms with the seller, not in the closing binder as an afterthought. A seller financing part of the price has even more reason to push the peg down, because it frees up cash they would otherwise leave behind.

Set the peg off a trailing average without checking which months it covers and you have accepted the seller's framing. The number reads neutral and is anything but.

How the adjustment settles at closing

The adjustment is a true-up. You compare the working capital actually delivered at close against the agreed peg, and cash moves to settle the difference.

Hold one deal in mind. Say the peg is set at $120,000, and at close the business delivers $95,000 of net working capital.

The business is short of its target by $25,000. The buyer's purchase price drops by that $25,000, or the seller wires the difference, so the buyer is made whole for the fuel that was missing.

Run it the other way and it reverses. If the business delivers $140,000 against a $120,000 peg, the buyer owes the seller $20,000 for the extra working capital handed over.

That swing is why two buyers at an identical headline price close at different real prices. One negotiated a peg that protected their cash; the other inherited an empty tank and paid the same sticker.

This true-up is one of the cash needs that land at the closing table, alongside the down payment and fees. Budget for it, because it can move in either direction and you will not know which until the closing balance sheet is final.

What getting it wrong costs the buyer

A peg set too low does not announce itself at close. It shows up six weeks later, when receivables have not converted and the payables are due.

Walk the cash through. The buyer who financed the purchase, often through an SBA 7(a) loan, now services that debt out of the cash the business produces.

• Month one: payroll, rent, and supplier invoices come due on schedule.
• Weeks four to eight: the receivables you bought are still being collected, so cash in lags cash out.
• The gap: if the delivered working capital was thin, the buyer covers that gap from personal cash on top of the loan payment.

That is the survivability hit. The business can be truly profitable and still squeeze a new owner who funded the deal but not the float.

The damage is worst in month one, when the buyer has the least slack. The loan payment is fixed, the receivables you bought are still in transit, and a thin peg means there is no reserve standing between the two.

This is the buyer cash-flow conversion the seller's numbers never show you. Place working capital inside the larger question of what the business is actually worth to you, and a thin peg is a quiet markdown on the deal you thought you negotiated.

The risk compounds against an owner-dependent business, the kind that already transacts near 1.65x instead of 3.5x. An owner-dependent operation is fragile on its own; pair it with a starved cash position and the first slow quarter does not get absorbed, it gets felt.

That pairing is what ends new owners in their first year. The peg is not paperwork; it is the difference between a business that funds itself and one you keep alive out of pocket while it finds its feet.

How to protect yourself in diligence

You protect the cash position before you sign, not after. The work is verification, and it belongs in the same pass as the rest of your diligence on the balance sheet.

Run these in order:

1. Define the peg in writing. Pin the target, the trailing period it is built from, and the exact accounts included, before the purchase agreement is final.
2. Test the trailing months. Pull twelve months of balance sheets and check whether the average reflects a normal cycle or a flattering window the seller picked.
3. Age the receivables. Confirm the receivables in the target are collectible, not stale invoices that inflate the delivered number without producing cash.
4. Stress the first quarter. Model the business running for ninety days on the delivered working capital alone, with the loan payment included, and confirm it clears.

If the stress test does not clear, the peg is wrong or the price is. Either is a reason to renegotiate, and finding it in diligence is the entire point of diligence.

A buyer who walks through these four steps is the buyer who funds the business, not the buyer the business drains. The number was always going to matter; the only question is whether you set it or the seller did.

FAQ

What is working capital in a business acquisition?

Working capital in a business acquisition is the cash and near-cash assets a business needs to operate, minus its short-term liabilities, delivered to the buyer as part of the purchase price. It is the operating fuel that lets the business run from day one without the buyer injecting more cash.

What is a working capital peg?

A working capital peg is the target level of net working capital the seller agrees to deliver at closing, usually set from a trailing twelve-month average. If the business delivers less than the peg, the price adjusts down or the seller pays the shortfall; if it delivers more, the buyer pays the difference.

Who pays for working capital in an acquisition?

Working capital is paid for through the purchase price, not on top of it, because the seller delivers an agreed level as part of the deal. The closing true-up then settles any gap between the peg and the actual balance, so whoever delivered too little or too much owes the difference.
