Complete agreements faster, close more deals and increase sales. Automate the entire contract process and securely manage how and where you centralize your documents.

  2. Get contracts signed 70% faster than before.

What our partners say

The system is very straightforward; our programmer could easily work with it. The same goes for the end-users: they find Sign very simple, pleasant and intuitive to use. Actually, it is quite difficult not to understand Sign.

LIFT Software

Sign plays an important role in the placement of candidates. We use it for our recruitment and staffing software. We experience Sign as a very flexible product; it works extremely easily and intuitively.


Many people do not even have a printer in their home. The traditional printing, signing and sending of a contract is then not possible. The signing process with Sign is fast and accurate. The digital signing including sending takes less than two minutes.


The use of Sign is very transparent and simple. There are no hidden costs and the customer pays according to usage.


Digital signing fits in this time period and we want parents to sign the contract when and where they want. For us, it is important to keep track of the status of contracts and signing. Sign provides that well.
