eSignatures.com

eSignatures.com is electronic signature software and a REST API for businesses and developers sending contracts, priced per contract with no subscription.

eSignatures.com sends contracts for signature as responsive text pages that open cleanly on a phone, rather than as PDFs that need zooming. An independent company in Melbourne, Australia, has built and run it since 2017. Signed contracts are legally binding under the US ESIGN Act and UETA, eIDAS in the EU and UK, and the electronic transactions laws of Canada, Australia and New Zealand. Each completed contract arrives as one PDF recording who signed, when, from which IP address and after which checks. Contracts start from templates, and Placeholders personalize each one before it goes out, filled by hand, from a spreadsheet or through the API. Signer fields collect text, dates, dropdown choices, checkboxes and file uploads during signing. Bulk sending turns a pasted spreadsheet into separate contracts, each with its own signers and audit trail. Contract links publish one agreement as a link, a QR code or an embedded form, and every submission becomes a contract of its own. The eSignature API sends contracts, embeds signing in another product and reports each event through webhooks, while Branding puts the sender's logo, letterhead and fonts on pages and emails. The service suits developers and SaaS products that want signing inside their own app, and businesses whose contract volume rises and falls. Insurance and health enrolment teams, clinics, agencies and fintech firms are the high-volume senders it is built around, and health workflows can run under a signed BAA. It is bought per contract from prepaid credits rather than by seat or subscription, so a whole team can be invited at no extra cost. Permissions then decide who sends contracts, manages templates, handles billing or administers the API. Waivers, intake forms and event registrations go out as Contract links on a website or a printed QR code, and each signer confirms with a code, so no submission is anonymous. Teams on WordPress embed a signing page or a contract button in their own site. Zapier and Make start a contract from a form entry or an HR system and react when it is viewed, signed or declined. Because the contracts are structured text, Claude and other MCP-enabled assistants can draft, fill and send them, and the ChatGPT plugin reports who still has to sign. It fits teams that send routine agreements in quantity and expect most signers to open them on a phone.
