    The choice between locked box and completion accounts
    decides millions.

    Locked box or closing accounts? Both purchase price mechanics have their merits, but the wrong choice costs money. Those who don't understand the mechanics negotiate blind.

    Battle-tested. Price-neutral advice. SME focus.

    Why pricing mechanics delay deals

    I don't know whether locked box or closing accounts is better suited for my transaction.

    The other side insists on closing accounts while I would prefer locked box, and vice versa.

    I don't understand the leakage provisions in a locked box and don't know what counts as permitted leakage.

    The completion accounts clauses are complex and I fear renegotiations over the final purchase price.

    Does this sound like your situation?

    Let's clarify in a free initial consultation whether and how we can help.

    Two pricing mechanics compared

    In a locked box, the purchase price is fixed based on a historical balance sheet date. The economic transfer takes place before the legal closing, and the price is fixed from that moment on. Leakage provisions protect the buyer from value outflows between the reference date and closing. With closing accounts, the final purchase price is calculated only after closing based on a balance sheet at the closing date. Adjustments for working capital, net debt and cash are standard. Both mechanics have advantages and disadvantages depending on transaction structure, sector and negotiation position.
    In Europe, the locked box dominates (approx. 60-70% of PE transactions). In North America, closing accounts are standard. In the German mid-market, both variants are used, with an increasing trend towards locked box.

    Our approach to pricing mechanics optimisation

    01

    Mechanics assessment

    Analysis of transaction parameters: Which mechanics suit the size, sector and timing of the deal?

    02

    Reference balance sheet review

    Review of the locked box reference balance sheet or definition of the working capital target for closing accounts.

    03

    Leakage / adjustment logic

    Design of leakage provisions (locked box) or working capital adjustment mechanics (closing accounts).

    What does the wrong pricing mechanics cost?

    • Purchase price difference: 2-5% purchase price difference through mechanics choice alone - on a EUR 20m deal, that's EUR 400,000 to EUR 1,000,000.
    • Post-closing disputes: Closing accounts adjustments lead to disputes over the final purchase price in 30-40% of cases.
    • Time loss: Closing accounts extend the transaction process by 4-8 weeks - a window in which deals can fail.
    • Leakage risk: Without cleanly defined leakage provisions in a locked box, the seller can extract value before closing.
