Digital signatures, built into every document
Capture company and counterparty signatures on Sales Orders, Purchase Orders, Invoices, Bills and Deliveries — with a compliance-grade audit trail, a configurable enforcement gate, and passwordless email-to-sign for customers and vendors.
The problem
Signatures on sales orders, invoices, vendor bills, purchase orders and delivery slips still happen out-of-band — printed, signed by hand, scanned, and manually reattached to the record, or skipped entirely. That means confirmation delays waiting on a signature, no reliable proof of who signed what and when, and hours lost reconciling paperwork back to the right document.
The solution
Digital Signature Pro turns signing into a step inside the document lifecycle itself. Request a signature from any Sales Order, Purchase Order, Invoice, Bill or Delivery Order, capture the company sign-off and the customer or vendor signature on the same record, and optionally block confirmation until both are in place — all logged in a compliance-grade audit trail.
Everything you need to sign, enforce and track
Every capability below is implemented in the module.
Multi-Document Signing
Sign Sales Orders, Purchase Orders/RFQs, Customer Invoices, Vendor Bills and outgoing Delivery Orders from one unified app.
Dual Internal + External Signatures
Capture the company sign-off and the customer or vendor signature on the same record, each clearly labelled with signer and timestamp.
Compliance-Grade Audit Trail
Every signature event logs signer name, role, timestamp and IP address in an immutable, create-only audit log.
Configurable Enforcement Gate
Turn on a hard, per-document-type gate that blocks confirm, validate or post until the document is signed.
Passwordless Email-to-Sign
A direct secure link opens a minimal signing page for the customer or vendor — no portal login, no navigation required.
Signature Status Dashboard
One kanban and list view shows every document that is draft, sent, internally signed, or fully signed across all document types.
Automated Reminder Emails
A daily scheduled action nudges customers and vendors on unsigned documents, with a configurable delay and maximum reminder count.
Bulk Signing & Reminders
Select many documents from any list view and request signatures or send reminders across the whole batch in one action.
Signature Certificate PDF
Print a dedicated Signature Certificate with both signatures, timestamps, IP and the audit log — without altering your original report.
How it works

Sign Internally
The company signer captures their signature by freehand draw or file upload.

A passwordless email link lets the customer or vendor sign in one visit, no login required.
Track & Enforce
The dashboard shows signed, pending and overdue status; the enforcement gate blocks confirmation until signed.
