Pick the range that matches the use case. We size the mix in the free 30-minute review.
Class 3 individual token
One certificate, one signatory, one FIPS-grade USB token. This is what directors, partners and authorised signatories carry for MCA, income tax, EPFO and GeM.
- Same-day issuance with PAN, Aadhaar and video KYC
- Works across MCA, IRP, ICEGATE, GeM and EPFO
- Supported tokens include HYP2003 and ProXKey
- From roughly ₹1,500 for two years*
Class 3 combo with encryption
Signing plus encryption on the same token. Government e-tender portals ask for the encryption key when bids carry sealed price envelopes. Buying signing only and upgrading later means a second KYC cycle.
- Mandatory for most e-procurement and e-auction portals
- The add-on typically runs about ₹1,000 over signing only
- One token carries both key pairs
- From roughly ₹2,400 for two years*
Document Signer Certificate
A server-side certificate that signs IRP e-invoices, MCA attachments and ICEGATE outputs automatically. Past about 600 signed events a year, the USB-token-in-a-drawer model starts costing real hours.
- No physical token to lose or pass around
- Wired into the finance workflow in days
- Suits e-invoicing mandates and bulk filings
- From roughly ₹4,500 per year*
Managed emSigner retainer
The issuance calendar, the renewal calendar and the lost-token workflow, run for you. Quarterly posture check with the finance head, 24-hour token replacement, one PO and one invoice for the whole signatory fleet.
- Every signatory’s expiry tracked in one place
- Renewals start 45 days before expiry, not after
- Lost USB tokens replaced in 24 hours
- From ₹24,500 per tenant per month*
eMudhra DSC vs Capricorn, Pantasign, Cloud
All four are honest choices. Most Indian buyers land on the first option for service depth and ecosystem fit.
| Brand | Where it wins | Best fit |
|---|---|---|
| eMudhra | The largest licensed CA in India, 60 million-plus certificates issued, same-day issuance when KYC is clean, and the emSigner workflow for teams that sign at volume. | Firms with several signatories, IRP e-invoice volume, or a compliance calendar that cannot slip. |
| Capricorn | Aggressive partner pricing and a very wide reseller network, so single tokens often land a few hundred rupees cheaper. | Price-first buyers who need one or two tokens and are happy to run their own renewal dates. |
| Pantasign / Vsign | Newer CAs with quick paperless flows and competitive rates through filing agents. | One-off purchases through a CA or CS who handles the paperwork anyway. |
| Cloud e-sign platforms | DocuSign, Adobe Acrobat Sign and Dropbox Sign are built for contract workflows, approvals and audit trails on commercial paper. | Sales contracts and HR letters. They do not replace a Class 3 DSC on MCA, IRP or tender portals. Most firms end up running both. |

eMudhra DSC India FAQ
Common questions about this brand for Indian buyers. Hover any underlined term for a plain-English definition.
What does an eMudhra digital signature cost in India?
An eMudhra Class 3 individual digital signature costs roughly ₹1,500 to ₹1,800 for two years including the USB token, the signing plus encryption combo runs about ₹1,000 more, and server-side Document Signer Certificates start near ₹4,500 per year. GST at 18 percent applies, and managed multi-signatory retainers start at ₹24,500 per tenant per month.*Is a Class 3 DSC mandatory, and what happened to Class 2?
Class 2 certificates stopped being issued from January 2021. Class 3 is now the single class for MCA, income tax, GST, EPFO, ICEGATE and tender portals, for individuals and organisations alike. Any old Class 2 token still in a drawer is decorative.How fast can a certificate be issued?
Same day, when documents are clean. Individual certificates need PAN, Aadhaar and a short recorded video. Organisation certificates add the company document set and a verification phone call, which usually adds a day.Do I need the encryption combo or is signing enough?
Signing alone covers MCA, income tax, EPFO and GeM registration. Most government e-tender and e-auction portals additionally require the encryption key for sealed bids. If anyone in the firm touches tenders, put the combo on their token from day one.What happens when a signatory loses the USB token?
Without a plan, a fresh application and fresh KYC, typically a week. Inside the managed retainer, a replacement certificate on a new token inside 24 hours, with revocation of the lost one handled the same day.Know your signatory count, or not sure who is carrying which token?
Send the list, or just the headcount. Sirius Star maps every certificate, expiry and portal in a free signing review, returned inside 24 working hours.
