What they say about us

No-brainer pricing for a small business - or even big business, I reckon : - )

Tried the product. Worked like a charm. Never had any problem + the clean UI got us. Wish there would be more features, but I believe in the team behind.
Harsh G.
Founder, CEO
SignHouse has been nothing short of convenient, efficient and fast. Oh and top notch customer support too...

Couldn't ask for more!
Julie M.
Executive Administrative Assistant
SignHouse has made a big difference in the workflow of my business. Sure there are other, more mature e-signing platforms out there, but they are all convoluted and too focused on big, enterprise companies. It feels like SignHouse is on our side.
Michael B.
Photography Consultant
Getting documents to parents is significantly simpler now. However, even more importantly, parents aren't getting lost in the signing process anymore. 👍
Sandy T
SignHouse was AMAZING for what we needed. "Do one thing and do it well" - they've nailed that, as everyone is very happy with the product here.

Looking forward to seeing how the product develops, as the team is super ambitious.
Kate Gross
Manager at
"Simpler, yet does the job better than most of the clunky eSignature software out there"
"SignHouse cut down on our signing processes by at least 50% - and we were using eSignature software before as well"
"I just never thought signing documents can ever become a pleasurable experience"

Frequently asked questions

Are your electronic signatures legal?

Our signatures are 100% legally binding, as SignHouse is built around US and International Laws concerning digital signatures. SignHouse eSignatures are on par with paper signatures, from a legal point of view!

Signing papers digitally started being equal to physical, handwritten signatures in the U.S. eSignature Act of 2000 (U.S. Federal Act) + the Uniform Electronic Transaction Act (UETA). As a consequence, laws in other countries have followed suit. SignHouse is built around these laws.

Are you adding an actual eSignature or just an image?

All signatures are a real, eSignature that is 100% legally binding.

We save important, relevant data (that can be used legally in all types of situations, including in courts) such as identifiable details of a person, IP addresses, etc, just so our electronic signatures can be as valid as digital signatures can get.

What about privacy and security?

SignHouse's signatures are secure for all kinds of businesses and companies. All our signatures happen on a secure, SSL-connected domain. Documents are not made public and unique keys are generated through SignHouse so that privacy and security are at the foundation of the documents on our platform.

How do my signees get to sign with SignHouse?

We've streamlined the signing process so that your signees can sign your documents with no hurdles at all — and with the smallest amount of steps required. It can take as little as 30 seconds! 

How do you compare to ______?

We have a generous free plan, so we highly encourage you to make the comparison yourself! It costs you nothing - and no hard feelings if you don't want to go with us.

We would really love to know what made you go with us or somebody else! If you could take a moment to write to us about that, we'd highly appreciate it.
