If you have to sign documents once in a while, are trying to save on printing paper, and are looking for a free alternative to DocuSign, here are a few you should check out, and how many documents you can sign per month on their freemium plan:
- SignRequest : unlimited
- ContractBook : unlimited signed, and you can send 3 per month. (UPDATE: ContractBook appears to just host signed docs, not sign them!)
- ConcordNow : unlimited signed documents for up to 4 people.
- EverSign : 5
- DocHub : 5
- eSignly : 3
If you're doing this professionally, DocuSign appears to be the leader, and there are platorm solutions I did not include, such as document signing tools that only work on iOS or Android.
