Escrow accounts and security deposits in B2B contracts: tied-up liquidity, accounting treatment, and release clauses in Switzerland

How to manage restricted deposits in construction contracts, M&A, and strategic supply agreements without compromising your SME's liquidity and accounting compliance.

Why escrow matters in Swiss B2B contracts

In commercial relationships between businesses in Switzerland, mutual trust is not always enough. Complex construction contracts, share acquisitions, bespoke supply agreements, or cross-border contracts often require the establishment of an escrow account or security deposit: a sum paid to a third party (usually a bank or trustee) and restricted until specific contractual conditions are met.

For an SME, the immediate effect is a reduction in available liquidity. CHF 50,000 or CHF 200,000 tied up for six months can jeopardise supplier payments, occupational pension (BVG/LPP) contributions, or simply the ability to respond to an opportunity. At the same time, escrow protects both parties: the client knows the funds are available if the supplier defaults, and the supplier knows payment is secured once the service is completed.

This guide explains how security deposits work in the context of Swiss contract law (CO), how to account for them correctly under Swiss accounting standards, and which release clauses to negotiate to limit the impact on cash flow.

Types of escrow and security deposits

Not all restricted deposits share the same legal structure or accounting treatment. Here is a concise comparison of the most common forms in B2B contracts:

Type Typical context Who holds the funds Liquidity risk
Tripartite bank escrow M&A, commercial property transfers, joint ventures Swiss bank with dedicated escrow agreement High — material amounts and extended duration
Security deposit (earnest money, Art. 158 CO) Construction contracts, industrial supply, operating leases Restricted account at the client's or supplier's bank Medium — often 5–15% of contract value
Retention money / guarantee fund Construction, IT projects, plant maintenance Withheld by the client or deposited with a third party Medium-low — residual percentage after delivery
Trustee escrow Transactions with suspensive conditions, earn-outs, ongoing disputes Independent trustee (Art. 394 et seq. and 472 et seq. CO) Variable — depends on duration of the suspension
Bank guarantee / surety Public procurement tenders, contracts with large clients Issuing bank — no transfer of liquidity Low — fee cost, not a cash tie-up

The distinction between true escrow and simple contractual retention is decisive: in the first case a third party ring-fences the funds; in the second the client retains control, with different implications for counterparty risk and accounting treatment.

Tied-up liquidity: operational and financial impact

Before signing an escrow clause, assess the effect on cash flow with the same rigour you would apply to a fixed-capital investment:

For the depositor (party paying in)

The payment immediately reduces available cash. If the funds come from bank credit, the cost of capital includes interest on the loan plus escrow fees (typically CHF 500–2,000 per year for standard accounts).

If the client becomes insolvent, a deposit paid directly to them generally forms part of the bankruptcy estate; with tripartite escrow, the funds remain segregated with the third party and the depositor can recover them according to the contractual conditions.

Monitor the ratio of tied-up liquidity to working capital: exceeding 15–20% signals a risk of strain on current payments, especially for SMEs with seasonal revenue.

For the beneficiary (party receiving the guarantee)

Escrow does not generate revenue until release conditions are met. It should not be confused with an invoice advance payment: until release, the counterparty holds a conditional right, not an enforceable receivable.

If the depositor becomes insolvent, the beneficiary can generally enforce the release conditions against funds segregated with the third-party agent (Art. 401 CO), without having to compete with ordinary creditors for the full guaranteed amount.

Numerical example — machinery supply contract

A Ticino-based manufacturer accepts an order of CHF 480,000 with a 10% escrow deposit (CHF 48,000) until commissioning and acceptance testing, estimated at 8 months. With a WACC of 6%, the opportunity cost of the tie-up amounts to approximately CHF 1,920. Annual bank fees must be added to this. By negotiating a partial release at 50% upon delivery, the manufacturer frees CHF 24,000 as early as month 4, reducing the opportunity cost by almost half.

Accounting under Swiss standards

Accounting treatment depends on the company's role in the contract and the legal nature of the deposit. SMEs subject to the Code of Obligations (CO) or applying Swiss GAAP FER must distinguish precisely:

Role Situation Typical accounting treatment Balance sheet note
Depositor Payment into bank escrow account Asset: "Restricted cash / escrow deposits" (reclassification from bank) Restricted assets — state amount and purpose
Depositor Earnest money or security deposit to client (no tripartite escrow) Asset: "Deposits and security paid" or "Other receivables from counterparty" Counterparty risk if client is insolvent
Beneficiary Escrow securing supplier performance Off-balance sheet until release — optional disclosure note Contingent commitments and guarantees received
Beneficiary Retention withheld on invoices issued Liability: "Liabilities for deposits received / retention" Obligation to repay when conditions are met
Depositor Escrow for acquisition (M&A) — suspensive condition Restricted asset; offset in "Advances on participations" or dedicated line item Subsequent event after year-end if condition is post-closing

Typical entries for the depositor. On payment: Debit "Escrow deposits" / Credit "Bank". On release to the beneficiary (default established): Debit "Losses on guarantees" or "Receivables from counterparty" / Credit "Escrow deposits". On release to the depositor (performance duly completed): Debit "Bank" / Credit "Escrow deposits".

VAT. The escrow amount is not in itself a taxable transaction. VAT arises at the time of the underlying supply (delivery, acceptance testing, closing). If escrow is used as a payment mechanism upon release, the invoice at the standard Swiss rate (8.1%) must be issued when the tax point arises, not at the initial payment into the restricted account.

Direct taxes. Interest accrued on the escrow account must be allocated for tax purposes to the economic owner of the deposit, as set out in the escrow agreement. Verify that the bank contract specifies the tax ownership of interest to avoid double reporting or omissions in the corporate income tax or personal income tax return.

Release clauses: negotiation and drafting

The quality of an escrow clause is measured by the clarity of release conditions and the predictability of timing. Essential elements to include or verify in the contract:

1. Objective release triggers

Define verifiable events: signed acceptance certificate, certificate of conformity, M&A closing memorandum, expiry of a warranty period without claims. Avoid vague wording ("client satisfaction") that leaves room for disputes and prolongs the tie-up.

2. Partial release and milestones

Negotiate progressive releases linked to work progress stages or partial deliveries. A release of 40% on delivery, 40% on acceptance testing, and 20% at the end of the warranty period balances client protection and supplier liquidity.

3. Dispute resolution mechanism

Provide for expedited arbitration (CAM or ad hoc arbitration) or an escrow release instruction procedure: if one party objects within X days, a jointly appointed expert or arbitrator issues binding instructions to the depositary bank.

4. Maximum duration and lapse

Set a final deadline: after 12 or 24 months without a written claim, funds automatically return to the depositor or are transferred to the beneficiary, depending on what was agreed. Without this limit, escrow can remain frozen indefinitely.

Operational setup and internal coordination

A well-managed escrow account requires coordination between finance, legal, and treasury. Recommended operational steps:

  • 1.Account opening: the Swiss bank requires the escrow agreement signed by all parties, a copy of the underlying contract, and up-to-date KYC. Opening takes 5–15 business days.
  • 2.Accounting tracking: create a dedicated analytical account or cost centre for each active escrow, with release deadlines and conditions in the subsidiary ledger.
  • 3.Treasury alerts: integrate escrow deadlines into the cash-flow forecast. An outgoing deposit should appear as a planned outflow; an expected release as an inflow.
  • 4.Audit trail documentation: retain release instructions, bank confirmations, and expert reports for at least ten years (Art. 958f CO; equivalent ten-year period for documents relevant for VAT purposes).
  • 5.Alternatives to cash: consider on-demand bank guarantees or insurance sureties if the liquidity tie-up is unsustainable — the annual cost (1–3% of the guaranteed amount) may be lower than the opportunity cost of immobilised capital.

Checklist before accepting an escrow deposit

Use this checklist to quickly assess an escrow proposal during contract negotiation:

Question Acceptable threshold Action if not met
Does the escrow amount exceed 10% of annual revenue? No, except for extraordinary transactions Negotiate a reduction or a bank guarantee
Are release conditions objective and verifiable? Yes, with clear milestones Redraft the clause with measurable criteria
Is a maximum duration provided? Yes, with automatic lapse Insert an auto-release clause
Is there a mechanism for rapid dispute resolution? Arbitration or expert determination within 60 days Avoid ordinary litigation as the only route
Have accounting treatment and VAT been defined? Yes, with an updated chart of accounts Consult your trustee or accountant before signing
Does projected cash flow support the tie-up? Minimum liquidity post-deposit > 3 months of fixed costs Renegotiate amount, duration, or funding source

With disciplined management — a clear contract, correct accounting, and treasury monitoring — escrow becomes a de-risking tool in Swiss B2B contracts, not an unexpected constraint on your company's liquidity.
