E-Signature & Digital Signing for ERPNext

ECOSIRE builds a proper Frappe app (its own module, not a pile of customizations) that closes that gap inside ERPNext. We add a Signature Request DocType that references the source document (Quotation, Sales Order, Contract, or any doctype you nominate) and renders the exact Print Format you already use. A drag-and-drop placement editor lets you drop signature, initials, date, and text fields onto the rendered PDF and bind each one to a specific signer. Recipients sign through a secure tokenized link — no ERPNext login required for external counterparties — and every event (viewed, signed, declined, IP address, timestamp, user agent) is written to an immutable Signature Audit Log child table. When the last required signer completes, a hooks.py doc event fires a server script that composes the flattened signed PDF, attaches it back to the source document via the Frappe File API, and updates status so downstream automation (converting a Quotation to a Sales Order, notifying the deal owner) can react.

Technically it is built the Frappe way, so it upgrades and audits like the rest of your instance. Signer routing supports both sequential (signer 2's link only activates after signer 1 completes) and parallel flows, driven by a Signing Template DocType that stores reusable field layouts and routing rules per document type. Whitelisted methods exposed over the Frappe REST API let you trigger sends programmatically or from a client script button on the Quotation form; scheduler events (scheduler_events in hooks.py) send reminder emails and expire stale requests. Role profiles and DocType permissions gate who can send, void, and download signed documents, and all signer PII and evidence stay inside your own ERPNext database and file store — nothing is farmed out to a third-party signing cloud unless you explicitly ask for a gateway integration. We target and test against Frappe/ERPNext v15 and v16.

Because this is build-to-order, you are not downloading a generic marketplace app and hoping it fits. We start with a short scoping call to confirm which document types you sign, your signer roles and routing, your print formats, and any e-signature compliance requirements in your jurisdiction. We then build against your actual ERPNext instance, prove it on a staging site with your real print formats during UAT, and only then install to production with a rollback plan. Typical delivery is 2–4 weeks from confirmed scope, and you receive the full app source and git repository so you are never locked in.
