Debt collection in Finland, what you can charge and when
Finland has a clear, structured process for getting an unpaid invoice paid, and it gives you more leverage than most freelancers use. Penalty interest starts the day after the due date, and on a business debt you can add a standard compensation without proving a thing.
What the law gives you before you do anything
Two things start working the day after the due date, whether or not you act.
Penalty interest. Under the Interest Act, a late payment accrues interest automatically. For 1 July to 31 December 2026 the reference rate is 2,5 per cent, which makes the penalty interest:
| 1.7.–31.12.2026 | |
|---|---|
| Commercial contracts (business to business) | 10,5 % a year |
| Otherwise, including consumers | 9,5 % a year |
The Bank of Finland resets these every six months. Check the period before you write a figure into a demand. This page names the period for that reason.
Standard compensation, on a business debt. Where the debtor is a business and a commercial contract payment is late, you are entitled to 40 euros as standard compensation for collection costs. You do not itemise it and you do not justify it. If your actual collection costs run higher, you can claim the excess above 40 euros on top.
Most freelancers never invoke either. They are both in the statute and neither needs permission.
Before you escalate: get the basics right
Collection works from documents. If the paperwork is thin, every later stage is harder.
- Clear invoices, sent promptly, with the payment term and reference stated.
- Agreed payment terms, in writing, before the work starts.
- A record of what was delivered and when: the thing a disputed claim turns on.
- A consistent follow-up routine rather than an ad hoc one.
The single most useful habit is boring: send the invoice the day the work is done. A large share of “the client is not paying” turns out to be “the invoice arrived three weeks late and went into the next payment run.”
The four stages
1. Payment reminder (maksumuistutus)
A polite notice that the due date has passed. Often that is the whole story: the invoice was missed, not refused.
Through an invoicing service the reminder goes out automatically, in the service’s name. That matters more than it sounds: it keeps the conversation between you and your client professional, because you are not the one asking.
2. Payment demand (maksuvaatimus)
A formal demand from a collection agency, stating the debt, the penalty interest and the collection costs, with a deadline.
This is the stage where most business debts settle, because it is the point at which ignoring the invoice starts to have consequences that show up elsewhere.
3. Tratta, business debtors only
A tratta is a public demand: if it goes unpaid, it can be protested and published, which reaches credit information. It is available only against businesses, not consumers, and it is effective for exactly that reason.
It is also not something to reach for lightly. It ends the client relationship.
4. Enforcement (ulosotto)
A court decision followed by enforcement. Slow and formal, and the route for a debt that is real, undisputed and simply unpaid.
A disputed debt does not go this way: it goes to court on the merits first, which is why the documentation in the first section matters.
What this looks like through an invoicing service
You do not run this process. It runs.
- The system tracks the due date.
- A reminder goes out automatically if payment does not arrive.
- Unpaid invoices move to collection, with established partners and processes.
- You are told where things stand.
Our own service is described on debt collection services.
Said plainly, because it matters: none of this guarantees you get paid. It is a process that pursues the debt properly and to the end. An insolvent client is not solved by any service, and the honest protection against that is a deposit or staged payments on large jobs, agreed before the work starts.
Five mistakes worth avoiding
Waiting. The longer a debt sits, the less likely it is recovered. The curve is steep after ninety days.
Not charging penalty interest. Waiving it is a choice you can make deliberately; not knowing you had it is not.
Chasing by feel. Three friendly emails at irregular intervals is not a process, and it reads as one you are not serious about.
Escalating a disputed invoice. If the client says the work was wrong, that is a dispute, not a collection matter, and collection will not resolve it.
Working on without a deposit for a client already late on the last invoice.

Frequently asked
- What penalty interest can I charge on a late invoice?
- On a commercial contract between businesses, 10,5 per cent a year for 1 July to 31 December 2026; otherwise 9,5 per cent. The Bank of Finland resets these every six months, so check the period before you put a figure on a demand.
- Can I charge for the trouble of chasing payment?
- On a business debt, yes: a 40 euro standard compensation for collection costs, with no need to itemise anything. Actual costs above 40 euros can be claimed on top, but only the excess.
- Do I have to chase the client myself?
- Not through an invoicing service. Payment monitoring and reminders run automatically, in the service's name rather than yours, and unpaid invoices move on to collection without you having to make the call.
