Put the agreement in writing while you still agree on it
You write the agreement on your own letterhead, the counterparty signs with MitID or with a single click, and it comes back timestamped and locked. From there you can invoice against it — and if the money has to be brought home later, the documentation is already in place.
Several hundred companies have automated their flow with Rieck.
What a signature is worth
How strong a claim stands is settled long before the due date
The terms are fixed from the start. Amounts, deadlines and parties get written down while everyone still agrees on them. The day somebody sees the matter differently, the paper is already there.
An accepted claim takes the short route. Once the debtor has signed for what is owed, the claim does not have to be proven first. It can go straight towards enforcement.
A debt instrument keeps a claim alive for ten years. The signature moves the limitation period from three years to ten, and the claim can be enforced without a fresh case having to be brought.
How it works
The road from draft to signature — and what the agreement does afterwards
Write
You write the agreement on your own letterhead
Begin with a template or a blank document, and fill in terms, amounts, parties and duration. It goes out with your logo and your name, so it looks like everything else the counterparty gets from you.

Sign
The counterparty signs with MitID or with one click
They get a link, read the document through and sign. Use MitID when the agreement has to carry a claim; the ordinary digital signature is enough when a documented acceptance will do.

Lock
The signature locks the document straight away
Both parties receive the same timestamped copy, and the content stands from then on. From there you can invoice on top of the agreement and lean on it if the money has to be brought home later.

The basis
Everything that comes afterwards stands on the same agreement
The invoice, the payments, the instalments and any collection case look like separate things. They all draw their basis from the agreement, and they are exactly as strong as it is.

In court
Where the claim stands if it reaches the bailiff’s court
An accepted, undisputed claim skips the dispute. And if it grows beyond the DKK 100,000 the simplified procedure covers (section 477 b of the Danish Administration of Justice Act), Rieck Advokater carries the case on — same case, same case number.
