How to Use Summa GoSign for Digital Signing

This section explains the two primary workflows: signing a document yourself and requesting signatures from others.

Signing a Local PDF (Self-Signing)

1. Open the software and click “Sign Document”.

2. Import your certificate – Select your smart card or a PFX file stored locally.

3. Place signature fields – Drag the “Visual Signature” block onto the PDF.

4. Configure appearance – Choose whether to show a handwritten image, text only, or a seal.

5. Click “Sign” – The software hashes the document and applies the digital signature.

Sending a Signature Request (Remote Workflow)

1. Click “Request Signatures” on the dashboard.

2. Add recipients – Enter email addresses and define signature order (sequential or parallel).

3. Define fields – Assign each recipient specific fields (e.g., “Client signs here”).

4. Send – Summa GoSign uploads the document to its secure relay server.

5. Track status – Monitor completion via the “Outbox” panel.

Best Use Cases for Summa GoSign Pro

The Pro version excels in regulated environments. Here are three real-world applications.

1. HR Onboarding Automation

HR teams can create a template pack (offer letter, tax forms, handbook acknowledgment). With bulk signing, they send 200+ packages simultaneously. The audit trail provides legal defense in case of disputes.

2. Procurement Contracts

A procurement manager signs NDAs with 15 vendors. Using sequential signing, the legal team reviews first, then the manager signs. The final document is sealed with a timestamp from a trusted authority.

3. Notary-Ready Documents

For real estate transfers, users combine a visual signature with a visible seal. The long-term validation (LTV) feature ensures signatures remain verifiable even if the original certificate expires.

Advantages and Limitations

Advantages

• Legally binding: Compliant with eIDAS Advanced and Qualified levels.

• Offline capability: Sign documents without an internet connection.

• High automation: CLI (Command Line Interface) for scripted signing in CI/CD pipelines.

• Transparent logging: Every action is recorded in a human-readable JSON audit trail.

Limitations

• No native Linux client: Requires a Windows VM or Wine (not officially supported).

• Learning curve for templates: Advanced field mapping requires studying the user manual.

• Price point: Pro starts at €29/user/month (billed annually), which exceeds basic tools like DocuSign’s personal plan.

Top Alternatives to Summa GoSign

Choosing the right software depends on your signing volume and compliance needs.

When to choose Summa GoSign: If you already use a physical smart card (e.g., Belgian eID, Estonian ID card) and need offline signing. For pure cloud-based workflows, Adobe or DocuSign offers simpler collaboration.

Frequently Asked Questions

1. Is Summa GoSign 4.0.0.401 legally compliant in the US and EU?

Yes. The software adheres to eIDAS Article 27 (Qualified Signatures) and the ESIGN Act. Signatures created with a valid certificate have the same legal weight as handwritten ones.

2. Can I use Summa GoSign Pro on multiple computers?

The Pro license allows activation on two devices simultaneously. To move to a third, deactivate one device via the license management portal.

3. Does Summa GoSign store my documents on its servers?

Only for remote signature requests. For local signing, documents never leave your machine. Cloud-stored documents are encrypted using TLS 1.3 in transit and AES-256 at rest.

4. What file formats does the software support beyond PDF?

It natively supports Microsoft Word (.docx) and Excel (.xlsx) by converting them to PDF/A internally. Image formats (JPEG, PNG, TIFF) are also convertible.

5. How do I renew my signature certificate?

The software notifies you 30 days before expiration. You must contact your certificate authority (CA) (e.g., GlobalSign, Swisscom) directly. Summa GoSign does not issue certificates; it only uses them.

6. Why does my smart card fail to work with Summa GoSign?

Ensure you installed the manufacturer’s PKCS#11 driver. Common cards (Gemalto, Feitian) require separate middleware. Go to Settings > Security Modules and manually load the .dll file.

7. Can I sign a document that already has digital signatures?

Yes. Summa GoSign supports incremental signing. It adds a new signature layer without invalidating previous ones.

Final Thoughts

For organizations regulated by eIDAS or those that rely on hardware security modules (HSMs) or smart cards, Summa GoSign 4.0.0.401 Pro is an excellent choice. It provides transparency, strong offline capabilities, and robust audit logging.

However, for casual users or small teams that only need basic click-to-sign functionality, the Pro version may be overkill. The free tier of Summa GoSign (limited to 5 documents/month) or a lower-cost cloud alternative like SignNow might serve you better.
