Abstract: Techniques for electronic signature processes are described. Some embodiments provide an electronic signature service (“ESS”) configured to facilitate the creation, storage, and management of electronic signature documents. The ESS may facilitate payment processing via an electronic signature document that includes or is associated with a payment form. When the signature document is presented to a user for signature, the payment form collects payment data (e.g., card type, account number, name) that is used by the ESS to process payment upon completion of the signing process.
