Deal Mechanics

Working Capital in a Business Acquisition

A profitable company can still fail immediately after closing if it arrives without enough working capital. The purchase agreement should define which current assets and liabilities transfer, establish a normalized target, and provide a clear closing adjustment.

Define the Operating Assets

Working capital usually focuses on operating current assets less operating current liabilities. Cash, debt, income taxes, and transaction expenses are often treated separately, but the exact definition must be written for the deal.

Map every account to included, excluded, debt-like, cash-like, or disputed. Account names alone are not enough. A liability labeled accrued expense may contain payroll, customer obligations, owner items, or transaction costs.

Calculate a Normalized Target

Review monthly balances across enough periods to capture seasonality and growth. A simple year-end snapshot can understate the amount required during a busy season or overstate it after a temporary build-up.

Adjust historical balances for unusual collections, delayed vendor payments, owner practices, discontinued lines, and changes in revenue scale. Explain the target in operating terms, such as the number of receivable days and payable days it represents.

Protect Against Closing Manipulation

A seller can temporarily collect receivables aggressively, delay purchases, postpone payments, or build inventory differently before closing. The agreement should require ordinary-course operation and consistent accounting.

Use a closing estimate followed by a post-closing true-up with defined documents, deadlines, and dispute procedures. Avoid vague language such as normal working capital without a formula.

Separate Working Capital From Cash Reserves

Receiving the agreed working-capital target does not eliminate the need for a buyer reserve. Unexpected repairs, customer losses, payroll timing, and integration expenses can still consume cash.

The acquisition model should show the contractual working-capital delivery and a separate post-closing liquidity reserve so neither is counted twice.

Buyer Checklist

  • Define included current accounts
  • Classify cash-like and debt-like items
  • Analyze monthly seasonality
  • Normalize unusual collection and payment patterns
  • Set an explicit peg or target
  • Create estimate and true-up procedures
  • Maintain a separate operating reserve

Frequently Asked Questions

What is a working-capital target?

It is the agreed level of normalized operating current assets minus operating current liabilities that the seller must deliver at closing.

Why not use the latest balance sheet?

A single date may be distorted by seasonality, growth, delayed payments, unusual collections, or seller behavior.

Is cash included in working capital?

Transaction definitions vary. Cash is often treated separately in a cash-free, debt-free deal, so the agreement must be explicit.
