Documenso

What Documenso is

An agreement needs to be signed. You print it, someone signs it, someone takes a photo with their phone, the image comes out crooked, and in the end there is a blurry photo in a chat that nobody can find in March. That is how it works at a great many companies.

Documenso does it digitally. You upload a PDF, mark where the recipient should write their name and add their signature, and send it off. The recipient gets a link, signs in the browser without having to create an account, and both of you get a finished PDF back. The system logs who opened the document and when it was signed.

On top of the handwritten signature, Documenso adds a digital signature to the PDF file itself. It works like a seal: if someone changes a single character in the document afterward, it can be detected.

Using Documenso on Windows and Linux Mint

Documenso runs in the browser, so there is no program to install and no difference between operating systems.

1. Go to documenso.com and create an account on the service they run themselves.
2. Confirm the email address. Use the company's shared address, not your private one; the agreements should be accessible even the week you are sick.
3. Draw your signature once in the settings. It is saved and reused.

The person signing does not need an account or an app. A link and a browser are enough, which is the whole point when the recipient is a store manager with five minutes to spare.

Three things to do first

1. Send a test agreement to yourselves. Upload any PDF, set yourselves as recipients and go through the whole chain. Then you know exactly what the customer sees before a real customer sees it. Expect the test to cost one document: the free plan holds five documents per month, and the test agreement is one of them.
2. Check the order of the recipients. If your advisor is to sign after the customer, set the order deliberately. Otherwise everything goes out at the same time and no one knows who is waiting for whom.
3. Decide where the finished files end up. Download the signed PDF and put it in the company's document folder with the date in the file name. An agreement that only exists inside a service is hard to bring along if you switch providers.

The most common trap

If someone in the company wants to run Documenso on your own server, this is what you need to read carefully. A self-hosted installation requires your own signing certificate, a so-called p12 file, and without it the system cannot complete the signing of a single document. You can create such a certificate yourself, for free, but the project's documentation is clear about the consequence: a recipient who opens the PDF file in Adobe's reader gets a warning that the signature cannot be verified instead of a green checkmark. A certificate from an approved issuer costs money.

Add to that the fact that the server also needs a working mail server to send the invitations, and a database that someone maintains. It is a real operations project, not an evening task.

The advice to a company: use the ready-made service, and put your energy into making sure the contracts are written correctly instead of keeping a server alive. If the question of the signature's legal weight comes up, take it to your advisor; that question is decided by what you have agreed on, not by which software you chose.
