Why B2B goods exchange is not a «zero-cost» transaction
In business-to-business relationships, payment does not always take the form of cash or bank transfer. Two companies may agree to a direct exchange of goods or services — the so-called barter or B2B swap — for example, a furniture manufacturer supplying furnishings to a communications agency in return for an advertising campaign, or two retailers exchanging inventory to optimise their product range.
From a Swiss accounting and tax perspective, the absence of money does not exempt the transaction from the usual obligations. Each party provides a taxable supply and receives consideration in kind. The Value Added Tax Act (VAT Act) and the Code of Obligations (CO) treat barter as two separate and independent transactions, each to be valued, documented, and recorded separately.
This guide explains how to value exchanged supplies, manage VAT, make accounting entries, and retain the necessary documentation, with reference to current practice in 2026 for SMEs and self-employed professionals operating in Switzerland.
Legal framework: barter, VAT, and accounting obligations
B2B goods exchange falls under several provisions of federal law. Here are the essential references:
Code of Obligations (CO)
Barter (Art. 237 et seq. CO) is a contract by which the parties mutually undertake to transfer ownership of goods or rights. Unlike a sale, the consideration is not money but an equivalent supply in kind.
For accounting purposes, this means that both parties must recognise revenue (or a cost) corresponding to the value of the supply provided and the supply received, regardless of the absence of a monetary flow.
VAT Act (MWSTG) and Ordinance (MWSTV)
Under Art. 18 of the VAT Act, supplies made for consideration fall within the scope of the tax. Goods exchange falls within this definition: each supply constitutes a separate taxable transaction, even if the consideration consists of goods or services rather than money.
Art. 24 para. 3 of the VAT Act provides that, in the case of barter, the consideration corresponds to the market value of the supply provided in exchange (net of tax).
Swiss accounting standards (Swiss GAAP FER or, for companies required to keep accounts on a double-entry basis under Art. 957 CO, the principles of proper bookkeeping) require revenue and costs to be recorded at current market value, ensuring a true and fair presentation of the financial position.
Valuation of exchanged supplies
Correct valuation is the prerequisite for VAT, profit tax, and financial statements. In the absence of a cash price, the market value principle applies:
Ordinary market value
This corresponds to the price an independent buyer would pay an independent seller under comparable market conditions. For standardised goods, use the current price list or the average selling price to other customers. For services, use the hourly rate schedule or the market price for similar supplies.
Valuation of non-fungible goods
For unique goods, commissioned works, or customised services, it is advisable to draw up a written quote agreed by both parties before execution. The signed quote constitutes the contractual basis and the reference for accounting and tax valuation.
Exchanges with dissimilar values
If the supplies do not have the same market value, the difference must be settled with a cash payment (barter with balancing payment). In this case, each party invoices its own supply at full market value; the cash balancing payment follows the ordinary rules for receipt and payment.
VAT treatment in B2B goods exchange
In a barter between two VAT-registered businesses, each party issues an invoice for its own supply. There is no single «net invoice» that offsets the two transactions: the Federal Tax Administration (FTA) treats the exchange as two separate supplies.
| Scenario | Taxable base | VAT rate | Invoicing obligation |
|---|---|---|---|
| Exchange of taxed goods ↔ taxed goods | Market value of each supply | 8.1% (standard rate) or 2.6% (reduced rate) | Invoice from both parties |
| Taxed service ↔ taxed good | Market value of the service and the good | According to the nature of each supply | Invoice from both parties |
| Barter with cash balancing payment | Full value of both supplies; balancing payment separate | VAT on the full value of each invoice | Invoices + balancing payment document |
| Exchange with exempt supply (e.g. export) | Market value; verify exemption conditions | 0% if export requirements met | Invoice stating the reason for exemption |
| Exchange with non-VAT-registered party | Market value for the VAT-registered party | VAT only on the supply of the VAT-registered party | Invoice issued by the VAT-registered party |
Under the effective method, each company declares VAT on sales and deducts it on purchases, subject to exclusions. Under the flat-rate method (Art. 37 VAT Act, for businesses with turnover up to CHF 5'024'000 and net tax up to CHF 108'000), tax is calculated by applying a sector-specific flat rate to taxable turnover, without analytical deduction of input tax: goods exchange nonetheless contributes to the turnover calculation.
Accounting: typical entries
Entries follow the logic of two mirror transactions. Below is a simplified example for an SME that supplies products worth CHF 10'000 (8.1% VAT included) and receives consulting services of the same value.
Sales side (supply provided)
- Debit: Accounts receivable — CHF 10'810 (gross incl. VAT)
- Credit: Sales revenue — CHF 10'000
- Credit: VAT payable — CHF 810
The receivable is cleared by recording the barter purchase, with no cash movement.
Purchase side (supply received)
- Debit: Service costs — CHF 10'000
- Debit: Input VAT — CHF 810
- Credit: Accounts payable — CHF 10'810
The payable is cleared against the receivable. The net effect on VAT depends on the deductibility of input tax.
In cost accounting, it is advisable to open a clearing account or use explicit offsetting between receivables and payables with the same counterparty, noting «barter offset» in the description to ensure traceability during audit or tax review.
Documentation and traceability
A well-documented B2B goods exchange reduces the risk of challenges from the FTA or the auditor. Checklist of documents to retain for at least ten years:
- 1.Barter contract or agreement — describes the subject matter, agreed value, timelines, and delivery conditions for both supplies.
- 2.Invoice issued and invoice received — each showing amounts at market value, the correct VAT rate, and a reference to the barter contract.
- 3.Delivery documents — delivery notes, service reports, or completion certificates for both parties.
- 4.Offset note — if receivables and payables are mutually cleared, an internal document confirming the clearing transaction with date and amounts.
- 5.Market value justification — price lists, quotes, or appraisals, particularly useful for non-standard goods or complex services.
Practical examples for Swiss SMEs
Example 1 — Full exchange between two traders
An electrical supplies retailer (A) supplies components worth CHF 5'000 to an installer (B) and receives in return a wiring service of the same economic value. Both are VAT-registered.
A issues an invoice to B for CHF 5'405 (8.1% VAT). B issues an invoice to A for CHF 5'405. Each records revenue/cost net of tax and handles VAT normally. The reciprocal receivables and payables are offset with no cash flow.
Example 2 — Barter with partial balancing payment
A graphic design studio (C) creates a logo and website (value CHF 8'000) for a restaurateur (D), who offers in return a catering service for a corporate event (value CHF 5'000). The CHF 3'000 difference is settled in cash by D to C.
C invoices CHF 8'648 to D; D invoices CHF 5'405 to C. D pays the net balancing payment of CHF 3'243 (difference between the two gross amounts). Both invoices show full market value, not just the difference.
Example 3 — Exchange involving a reduced-rate good
A food producer (E) supplies basic food products (2.6% VAT rate) to a hotel (F), which offers overnight stays (3.8% accommodation rate or 8.1% depending on the service). Each invoice must show the correct rate for the respective supply, even if the net values match.
The differing rates make separate and precise valuation of each supply even more important, avoiding the application of a single «average» rate that would not correspond to the correct tax treatment.
Tax implications beyond VAT
Profit and income tax
Revenue from barter contributes to taxable profit at market value, exactly like a cash sale. Similarly, the cost of the supply received is deductible if it meets the usual deductibility requirements (connection with the business, documentation, correct valuation).
Withholding tax
If one of the supplies involves a foreign self-employed person or a supply subject to withholding tax, the ordinary rules apply. Goods exchange does not exempt from withholding tax obligations when the nature of the supply requires it.
Common mistakes and how to avoid them
Not issuing an invoice «because there is no payment»
The absence of money does not exempt from the VAT invoicing obligation. Both parties must issue an invoice at market value. Failure to invoice exposes you to adjustments, interest, and penalties.
Valuing at production cost rather than market value
Using internal cost understates revenue and the VAT taxable base if the ordinary selling price is higher. Valuation must reflect the consideration that would have been obtained in a sale to a third party.
Offsetting invoices in a single document
Issuing a single «offset invoice» on a net basis does not replace the two separate invoices required by the VAT Act. Offsetting takes place at accounting or payment level, not at tax document level.
Treating barter as a gift or promotional giveaway
If there is a reciprocal contractual obligation, this is not a promotional giveaway (treated separately) but barter. Confusing the two concepts leads to errors in both VAT and cost deductibility.
Managing barter with accounting software
Goods exchange transactions require careful management of cross-invoices, offsets, and VAT entries. Accounting software such as Accountex allows you to issue invoices with differentiated rates, record payments by offset, track receivables and payables by counterparty, and automatically generate data for quarterly or semi-annual VAT returns.
Centralising contracts, invoices, and offset notes in a single system simplifies year-end financial statement preparation and reduces the risk of forgetting to include non-monetary transactions in taxable turnover. For SMEs that occasionally engage in barter, it is sufficient to configure the counterparty correctly and use the clearing function; for recurring exchanges with the same companies, it is advisable to create a standardised entry template.
