Inkassoloven §10: Your Inkassovarsel Guide
The inkassovarsel is the legally required 'last warning' before you can transfer a debtor case to inkasso. Get it wrong — miss a field, skip the deadline, or forget holiday adjustment — and the inkasso agency will refuse the case because it's legally unenforceable. This guide lists the exact 10 fields Inkassoloven §10 requires, how to calculate the deadline correctly, and the common mistakes we see every week.
What is an inkassovarsel and when is it required?
Inkassoloven §10 requires that before any Danish creditor transfers a debt to a professional inkasso agency (or a lawyer acting as an inkasso), they must send the debtor a formal notice with a minimum 10-day deadline. This applies to all B2B and B2C debts, all invoice sizes, and all overdue amounts — including if the debtor has ignored multiple rykkere already. The purpose is consumer protection: the debtor must have a final chance to pay before the case escalates and external collection costs start adding up. No inkassovarsel, no valid inkasso case.
The 10 mandatory fields
Inkassoloven §10 requires the inkassovarsel to contain: (1) creditor's name and address, (2) debtor's name and address, (3) invoice number or other clear identification of the debt, (4) total amount owed including any previously-added fees and interest, (5) original due date of the invoice, (6) legal basis for the claim, (7) clear payment instructions (account number, reference), (8) explicit statement that the case will be sent to inkasso if not paid, (9) the exact deadline date (not 'within 10 days' — an actual date), and (10) a brief description of the consequences of non-payment. Sitenyx's template generator populates all 10 fields automatically from the debtor and invoice records, so nothing is ever left blank.
The 10-day deadline: calendar days, holiday-adjusted
The 10-day deadline runs from the day the debtor receives the notice (or 1 business day after posting, for physical letters). The deadline MUST be calendar days, not business days — but if the 10th day falls on a weekend or Danish public holiday, the deadline extends to the next business day. Sitenyx uses an IDanishHolidayService that knows every Danish public holiday including Grundlovsdag, Store Bededag (abolished 2024), and regional holidays. If the 10th day is Easter Monday, the deadline automatically becomes Tuesday. This alone prevents one of the most common compliance mistakes we see.
Inkassogebyr: the one-time 100 DKK fee
When you send an inkassovarsel, you can add a one-time inkassogebyr of DKK 100. This is separate from the 3 rykkergebyrer you've already collected (max 300 DKK total) and from any morarente or kompensationsbeløb. The inkassogebyr applies once per invoice and is legally justified by Bekendtgørelse om udenretlige inddrivelsesomkostninger. Sitenyx adds it automatically when the inkassovarsel is generated, so you capture the full legal amount without extra admin. If the debtor pays within the 10-day deadline, you keep the fee — it doesn't refund.
Common mistakes we see every week
The three most common errors: (1) Missing the 'consequences of non-payment' field — most templates say 'will be sent to inkasso' but forget to spell out that the debtor will owe external collection costs on top. (2) Using a 'within 10 days' phrasing instead of an explicit date — this is technically compliant but inkasso agencies often reject it to be safe. (3) Sending via email without proof of delivery — for higher-value claims (> DKK 10,000), use registered mail or e-Boks so you can prove receipt. Sitenyx uses e-Boks integration by default for Danish debtors, which provides legal proof of delivery.
Conclusion
The inkassovarsel is your final compliance gate before inkasso. Every field, every day, every currency symbol matters. Automating it with Sitenyx removes the risk of human error and ensures every case that moves to inkasso is legally bulletproof. <a href="/business-tools/debtor-management">See how Sitenyx handles the full rykker-to-inkasso pipeline →</a>
Ofte stillede sporgsmol
Can I send the inkassovarsel by regular email?
For low-value consumer claims, yes — regular email is usually accepted. For B2B claims above DKK 10,000 or any claim where proof of receipt is critical, use e-Boks, registered mail, or a trackable delivery service so you can prove the debtor received the notice.
What if the debtor asks for an extension during the 10-day period?
You can grant an extension, but it extends the deadline for the same invoice — you don't restart the process. Document the extension in writing. Sitenyx's promise-to-pay module captures these extensions automatically and pauses the workflow.
Does the 10-day deadline apply to all invoice sizes?
Yes. Inkassoloven §10 applies regardless of invoice amount. Even a DKK 50 disputed invoice needs a valid inkassovarsel before inkasso can proceed. The 10-day deadline is non-negotiable.
