Digital Signature in TallyPrime: How to Secure Your Invoices and Reports

Introduction: Why Digital Signatures Matter in Modern Accounting

Imagine sending an invoice to a client worth ₹5,00,000.

The client receives the PDF and asks:

“How do I know this invoice is authentic?”

In traditional accounting, businesses used physical signatures and stamps.

But today most invoices are shared digitally through:

• Email

• WhatsApp

• Cloud systems

This is where digital signatures become essential.

With Digital Signature in TallyPrime, businesses can sign invoices electronically to ensure authenticity and prevent document tampering.

What Is a Digital Signature in TallyPrime?

A digital signature is an encrypted electronic signature that verifies:

• the identity of the signer

• the authenticity of the document

• whether the document was modified after signing

In TallyPrime, digital signatures can be added to:

• invoices

• accounting reports

• exported PDF documents

This feature ensures that documents shared with customers remain secure and verifiable.

Requirements to Use Digital Signature in TallyPrime

Before using digital signatures, you need the following.

1. Digital Signature Certificate (DSC)

A DSC token or dongle issued by a trusted certifying authority is required.

Examples include:

• eMudhra

• Capricorn

• Safescrypt

• Pantasign

• IDSign

These devices store your digital certificate securely.

2. Digital Signature PIN

When you purchase a DSC token, you receive a PIN code.

This PIN must be entered to authenticate the digital signature.

3. USB Token Connected to System

The DSC token must be connected to the computer running TallyPrime.

Without the token, the digital signature cannot be applied.
