For business owners preparing to sell, the net working capital (NWC) target is one of the most negotiated economic terms in a purchase agreement. It can potentially shift hundreds of thousands of dollars between you and the buyer at closing without a single change to the headline purchase price.
Definitions buried deep in the agreement, a poorly set NWC peg, or one mislabeled “debt-like” item can quietly erode the value you spent years building. The good news is this is preventable. With early financial modeling, clean legal agreement drafting, and a transaction team that understands where buyers attack the balance sheet, sellers can protect their economics and walk into closing with confidence that their closing economics will be as close to anticipated as possible.
This piece is the first in a two-part series. It breaks down what net working capital really means in a transaction, how the peg gets set, and how the methodology behind it holds up once diligence begins. Part two picks up where the buyer starts pushing on the number, covering the line-item battles, the closing statement, and dispute resolution.
At its core, net working capital equals current operating assets minus current operating liabilities. Think accounts receivable, inventory, prepaid expenses, accounts payable, and accrued operating liabilities. Cash, funded debt, income taxes, and debt-like items are typically excluded, but the specifics vary deal by deal.
The NWC you use to run your business on a day-to-day basis isn’t necessarily the NWC that shows up in your purchase agreement. Traditional working capital measures liquidity needed to operate, while transactional NWC is a negotiated construct used to calculate the purchase price true-up at closing. The two overlap, but they often diverge based on deal structure, diligence findings, and how the agreement gets drafted.
The purpose of the transactional version is simple in concept. The seller promises to deliver the business with a normalized level of working capital so the buyer can keep operating without injecting fresh cash into the business on day one. If actual NWC at closing falls short of the agreed target (the “peg”), the purchase price gets reduced dollar-for-dollar. If it comes in above, the seller benefits. That dollar-for-dollar mechanic is why getting the peg right matters so much.
The cash-free / debt-free framework: enterprise value gets adjusted by cash, debt, debt-like items, and the NWC true-up to arrive at what the seller actually receives.
The peg is your benchmark, and how it’s set determines a lot of the downstream economics of the transaction. Most pegs are based on a trailing average of NWC that is normalized for seasonality and one-time items, but the right approach depends on the business.
A simple historical average can mislead if the company is seasonal, project-based, or growing fast, and the right alternative depends on which of those situations applies. When recent performance better reflects how the business operates today, run-rate analysis often gives a cleaner read than a long-dated average. Seasonal businesses need monthly trend data to capture the working capital cycle accurately rather than a single point-in-time snapshot. Fast-growing businesses bring their own challenge: historical averages frequently understate the receivables and inventory needed to support continued growth, which is why setting the peg as a percentage of revenue may work better in those cases. Buyers tend to push back on growth-based methodology, so the commercial rationale needs to be documented clearly to hold up through diligence.
Whatever approach gets used, the peg methodology needs to be locked down in writing, typically defined as a formal calculation in the LOI or purchase agreement and supported by an illustrative example. The illustrative example walks through the calculation using recent balance sheet data, showing exactly which accounts are included, which are excluded, and how the math flows. Once both sides agree to it, the example becomes the reference point at closing and in any post-closing dispute.
That methodology work is also what lets your counsel draft the agreement properly. The attorney writes the Purchase Agreement, but it can only be as precise as the financial logic behind it. A well-built working capital peg methodology pulls the account-by-account schedule, the normalization adjustments, and the illustrative example into one defensible package, and that package is what counsel needs to write a tight definition of net working capital, attach the example calculation as a binding exhibit, and use “consistent with past practice” language that actually holds up. That handoff only works when your financial advisor and your counsel are in sync, both building from the same methodology. When the methodology is clear, counsel can draft language that closes the gaps. When it’s vague, the agreement ends up vague too, and that’s exactly where a buyer’s counsel goes looking for leverage.
One important note: locking in the peg before quality of earnings (QofE) work is complete creates real risk. Reserve shortfalls, revenue cut-off issues, or misclassifications discovered later can cause re-trades. Sellers should be cautious about hard-wiring a peg before they actually understand the normalized working capital need. Experienced bankers understand potential deficiencies and identify challenges early in the process.
QofE work almost always surfaces accounting items that affect the peg. Normalization adjustments, deferred revenue and revenue cut-off issues, reserve adequacy, and accrued liability treatment all spill into the NWC discussion. The purchase agreement needs to align with what diligence finds, otherwise you’ll have a methodology mismatch at closing.
Buyers often use QofE findings to push value in their direction. Common re-trade tactics include increasing the peg based on revised normalization views, reclassifying liabilities as debt-like, challenging A/R and inventory reserves, expanding transaction expenses, and exploiting GAAP ambiguity. Often they apply multiple pressure points at once, and it’s a deliberate leverage play. The more issues on the table, the more likely the seller concedes on at least some of them to keep the deal moving toward close.
Seller defenses are straightforward when set up early: lock peg methodology and tie it to an illustrative example, expressly define debt-like items with a no-double-counting clause, prepare aging and reserve support before diligence starts, define transaction expenses precisely, require GAAP consistent with past practices, and force issue-by-issue quantification so any double-dipping gets exposed.
Every common buyer tactic has a counter. The defenses work best when they’re built into the LOI and purchase agreement before diligence begins.
Net working capital should be treated as a core economic term, not a secondary legal mechanic addressed late in the process. The peg is where that economic term gets defined, so the methodology behind it deserves real attention long before a buyer is at the table.
Build the peg on a defensible, well-documented methodology and tie it to an illustrative example so it means the same thing to everyone. Use diligence to build a fact-based narrative for why your proposed peg is fair and sustainable, and get your financial advisor and your counsel working from the same analysis from the start.
The cost of getting this right is small relative to what’s at stake. Working with an experienced advisor early in the process, well before LOI signing, generally pays for itself many times over in preserved purchase price.

NWC doesn’t operate in a vacuum. Several adjacent issues shape how closing economics actually play out and deserve their own attention.
Pre-sale preparation matters more than most owners realize. The cleanest NWC outcomes come when the business’s accounting is as close to GAAP as possible 12-24 months before going to market.
EBITDA normalization runs in parallel during QofE, and the same accounting judgments often hit both. A peg set without a clean view of normalized EBITDA tends to create problems downstream.
Tax structure (asset vs. stock deal) affects which balance sheet items actually transfer, what stays behind, and how prepaid items, accruals, and tax balances get treated at closing.
Getting the peg right starts well before the LOI. We work with owners 12 to 24 months ahead of a transaction to clean up the balance sheet, normalize working capital trends, and pressure-test what the true operating need looks like across a full cycle. By the time a buyer’s QofE team shows up, the methodology is built, the seasonal swings are documented, and the supporting analysis tells your story instead of theirs.
That preparation only pays off if it carries into the agreement. We build the peg methodology, the account-by-account schedule, and the illustrative example into one package, then work alongside your counsel so the financial analysis and the legal drafting line up. Starting early gives you room to set the peg on your terms instead of reacting to the buyer’s once a process is already moving.
This kind of work sits at the core of every engagement we take on. NWC is one of several areas where the difference between a good banker and a great one shows up in real dollars at close. Owners who prepare the peg well before a buyer is at the table consistently keep more of what they’ve built. Putting our clients in that position is what we do.
