Get documents signed in seconds - either from the construction site or the company car

If you need a signature from an employee, partner or perhaps a customer, it can be done easily and quickly with Addo Sign - regardless where they are physically.

Even if they are on the construction site or in the company car, far away from the computer and the printer, they can sign directly on the mobile phone. This will allow you to get your document signed in an instant.

All you have to do is send the document - Addo Sign takes care of the rest using a series of automated processes that also include proper archiving. And if someone forgets to answer, Addo Sign will send a reminder - completely automatically.
