Funny, we've just replaced DocuSign with a custom-built solution that will achieve full ROI in less than one year, thanks to recent price hikes on the contract.
Can you share more about what it takes to build something that'll digitally sign documents that'll be recognized by most countries?
I wasn't involved in the legal side and am not a lawyer, but in my limited understanding of US contract law (where this is exclusively used) it is quite simple to create a binding contract that will stand up in court. Building it, if anything, showed how simple the process can actually be.
