Electronic signature firm DocuSign has been around since 2003. It allowed parties to contracts to sign from their computers, and later, from mobile devices. But users couldn’t pay at the time of signing — that required following up.

Today DocuSign introduced payment at signing, as well as partnerships with Android Pay, Apple Pay, Visa, Mastercard and (soon) PayPal. A step in the process that was manual and often involved paper checks can now be digital — provided the other party in the contract is able to accept the payment.

Payment at signing will be released in early 2017. DocuSign has $3 billion in funding, according to Crunchbase.
