How to recover an unpaid B2B invoice in Switzerland

To recover an unpaid B2B invoice in Switzerland, a creditor files a payment order with the debtor's cantonal enforcement office before any court gets involved. Most disputes are settled, paid, or abandoned at that stage – long before a judge ever opens the file.

When this route applies and when it does not

The Swiss enforcement route works when the debtor is a company or individual domiciled or registered in Switzerland, and the claim comes from a genuine commercial relationship: goods delivered, services rendered, an invoice past its due date with no serious dispute about the underlying contract. It is a state process open to any creditor holding a Swiss debtor, not a court action you have to build from scratch. Before you commit time to it, it helps to know the wider warning signs a Swiss counterparty is drifting toward insolvency, since those change which stage of the process is worth pursuing.

It applies badly when the debtor has already moved its operations, its bank accounts and its stock out of Switzerland, or when a bankruptcy proceeding against it is already open elsewhere. In that case the enforcement office can issue a payment order, but there is nothing left in the jurisdiction to seize once you reach the enforcement stage. If the debtor's assets sit in a different country, the more relevant question becomes how a Swiss or foreign judgment against that debtor actually gets enforced where the assets are, which is a separate and often slower exercise.

The sequence, as an ordered list of stages

The Swiss process is unusual among European systems because the first formal step is administrative, not judicial. It runs in a fixed order, and each stage gives the debtor a chance to stop it.

1. Formal reminder. The creditor sends a written demand stating the amount, the invoice reference, and the due date. You need the original contract or purchase order and proof of delivery ready at this point, because you will need them again later.
2. Payment order request. The creditor lodges a request with the enforcement office covering the debtor's registered domicile. The office issues the order and serves it on the debtor without assessing whether the claim is actually justified – that assessment comes later, only if the debtor contests it. The mechanics of this filing are covered separately for anyone handling their own first request.
3. Opposition. The debtor can lodge a formal opposition against the order without giving any reason. This single step is why the Swiss route surprises creditors used to other systems: an unjustified opposition stops enforcement just as effectively as a justified one, at least temporarily.
4. Removing the opposition. If the debtor opposes, the creditor must either apply to a court for authorisation to proceed, using documentary proof of the debt, or bring an ordinary claim on the underlying contract if no such proof exists. This is the point where the file either moves fast or stalls for a long period.
5. Continuation request. Once opposition is lifted or a judgment is obtained, the creditor asks the enforcement office to continue proceedings against the debtor's assets or, for companies, toward bankruptcy proceedings.

What drives the cost and the time

Two things decide whether this stays cheap and fast or turns into a real litigation file. The first is whether the debtor opposes at all – silence at that stage lets the creditor move straight to enforcement. The second is whether the creditor holds a signed acknowledgment of debt or an equivalent document. With one, removing an opposition is a summary procedure decided on paper. Without it, the creditor is pushed into an ordinary civil claim on the merits, with everything that involves: pleadings, evidence, and a court timetable set by the canton concerned.

Court fees, translation of foreign-language contracts, and the practical difficulty of describing a cross-border commercial relationship to a Swiss court add further weight. None of these figures is fixed nationally – procedure and fee schedules sit with each canton, and the continuation request itself sits inside a wider filing that assumes the reader already understands the sequence around it.

The decision point where the creditor chooses to continue or stop

The real decision arrives the moment the debtor opposes and no acknowledgment of debt exists. At that point the creditor is choosing between an ordinary court claim – slower, requiring full proof of the contract and the debt – and walking away. This is exactly where creditors who have not handled a Swiss debtor before tend to either overcommit on a weak claim or drop a claim that was actually straightforward to prove. Getting a clear read on which of those two situations you are in, before instructing anyone locally, is what separates a recovered invoice from a second loss on top of the first.

When to stop

Three situations make continuing the Swiss route cost more than it will ever recover.

• An earlier enforcement attempt against the same debtor already came back with no attachable assets. A second attempt on the same debtor, without new information about its position, usually repeats that result.
• The debtor disputes the underlying contract seriously, not just formally, and the invoice value does not justify a full ordinary claim once court costs and time are weighed against it.
• A bankruptcy proceeding against the debtor is already open. From that point, the claim belongs in the bankruptcy estate as a filed claim, not in a separate individual enforcement action.

Before deciding either way, it is worth running the numbers on your specific file through a structured assessment rather than a rough guess, since the cost of the wrong choice compounds quickly on a claim this size.

Common questions

Can a creditor start the Swiss enforcement process without a lawyer?

Yes, the initial payment order request is an administrative filing anyone can lodge. Court involvement, and the need for legal drafting, only arises once the debtor opposes and the matter has to move to a court decision.

Does an unpaid Swiss invoice stop being enforceable if the debtor ignores the payment order?

No. Silence from the debtor after service is treated as acceptance for enforcement purposes, and the creditor can move straight to the continuation request without further court involvement.

What happens if the Swiss debtor is a branch of a foreign company?

The enforcement office looks at where the debtor is actually registered and holds assets. A branch with no independent legal existence in Switzerland changes which entity the payment order should be issued against, and this needs checking before filing, not after.

An invoice that sits unpaid does not become easier to collect the longer it waits – other creditors of the same Swiss debtor are not waiting either, and whatever assets exist today are the ones actually available at the enforcement stage, not whatever is left once someone else has filed first. The choice in front of you is whether this file is still worth that race.
