Choosing the right digital signature solution can make Salesforce document processes faster and easier. Instead of downloading documents, sending them manually, and tracking signatures through emails, businesses can manage the complete signing process directly from Salesforce. This post will compare top Salesforce AppExchange apps for digital signature and eSignature.
What is a digital signature?
A digital signature is a secure way to verify that a digital document, message, or transaction is authentic and has not been changed after signing.
It uses cryptographic technology to connect the signer with the document. A digital signature can help verify:
- Who signed the document
- Whether the document changed after signing
- When the document was signed
- Whether the signature is valid
For example, when a customer signs a contract digitally, the system can create a secure record of the signing activity. If someone changes the document later, the digital signature may become invalid or show that the document was modified.
Why Is a Digital Signature Required?
Businesses use digital signatures to make document signing faster, more secure, and easier to track.
- Faster Document Signing
- Better Security
- Verify the Signer
- Create an Audit Trail
- Reduce Paperwork
- Improve Business Automation
Digital Signature vs eSignature
These terms are often used together, but they are not always the same.
| eSignature | Digital Signature |
|---|---|
| Electronic method of showing agreement or intent to sign | Uses cryptographic technology to secure and verify a signature |
| Can include typed names, drawn signatures, or click-to-sign | Typically uses cryptographic keys and certificates |
| Focuses on the signing experience and consent | Focuses on authentication, integrity, and security |
| Common for everyday contracts and agreements | Often used when stronger identity and document integrity controls are required |

Our rating: ⭐⭐⭐⭐⭐ — Best Adobe/PDF ecosystem choice
3. PandaDoc for Salesforce — Best for Sales Documents
PandaDoc goes beyond pure eSignature. Its primary strength is combining document creation, proposals, quotes, approvals, and eSignature workflows.
The AppExchange marketplace currently shows PandaDoc among popular Salesforce applications with 175 ratings. G2’s Salesforce AppExchange eSignature category also identifies PandaDoc as a defining product in this space, showing a 4.7/5 rating from 3,611 reviews on G2 as of its July 2026 refresh.

Our rating: ⭐⭐⭐⭐⭐ — Best for sales proposals and quotes
4. S-Docs — Best Salesforce-Native Alternative
S-Docs is particularly interesting for Salesforce customers who want to minimize dependence on external document-generation infrastructure.
The AppExchange listing positions it as a native document generation and eSignature solution, supporting PDF, Word, Excel, email, and forms. It had 462 ratings in the indexed AppExchange results, with a February 2026 release listed.

Our rating: ⭐⭐⭐⭐½ — Best native-focused option
5. Dropbox Sign — Best for Simple Workflows
Dropbox Sign, formerly HelloSign, is positioned on AppExchange as a straightforward solution to create, send, track, eSign, and save contracts without leaving Salesforce. The indexed AppExchange result shows 27 ratings and Salesforce support from Essentials upward.
Best for
- SMBs
- Simple contracts
- Basic approval/signing workflows
- Teams prioritizing ease of use
Potential drawback
Its Salesforce ecosystem footprint appears significantly smaller than DocuSign and Adobe based on AppExchange review volume.
Our rating: ⭐⭐⭐⭐ — Best for straightforward eSignature needs
6. Conga Sign — Best for Conga Customers
Conga Sign should be strongly considered if an organization already uses the Conga ecosystem for document generation, CPQ, contracts, or CLM.
G2’s Salesforce AppExchange eSignature category identifies Conga Sign as a Salesforce-focused eSignature option and describes it as enterprise-grade, integrated, customizable, and compliant.
Best for
- Existing Conga customers
- Contract-heavy organizations
- CPQ + document generation + agreement processes
Important note
I would not automatically select Conga Sign solely because Conga is well known. Its strongest case is when there is already a Conga ecosystem investment.
Our rating: ⭐⭐⭐⭐ — Best ecosystem choice for Conga users
7. signNow — Strong Value Option
signNow is worth including in a competitive evaluation, especially for SMB and mid-market customers.
G2’s current Salesforce AppExchange eSignature category shows 4.6/5 from 1,765 reviews and positions signNow as an intuitive electronic signature solution with a strong value proposition for SMB and mid-market businesses.
Best for
- Cost-sensitive organizations
- SMB and mid-market
- Mobile and straightforward signing scenarios
What to validate
Before choosing it for a Salesforce implementation, I would specifically validate:
- Depth of the current AppExchange package

- Document lifecycle management
- Reporting and status synchronization
Our rating: ⭐⭐⭐⭐ — Strong value contender
8. Portwood DocGen — Interesting New Native Option
Portwood is a newer option visible on AppExchange. Its listing describes a solution for generating Word and PDF documents directly in Salesforce, using merge tags, bulk generation, Flow automation, QR codes, and a 100% native architecture with no external services. The indexed listing showed 7 ratings and a July 14, 2026 release.
Best for
- Organizations wanting a native approach
- Teams exploring lower-complexity or newer alternatives
- Flow-driven document automation
Caution
Because its AppExchange review volume is much smaller than established leaders, I would run a proof of concept before selecting it for a mission-critical enterprise implementation.

Summary
Salesforce AppExchange offers several strong digital signature and eSignature solutions. Each product targets different business needs, so there is no single solution that fits every organization.
DocuSign is the best overall choice for enterprise Salesforce implementations. Adobe Acrobat Sign works well for businesses that already use Adobe and rely heavily on PDF documents. PandaDoc is a strong option for sales teams that need proposals, CPQ, document generation, and eSignatures in one workflow.
For organizations that prefer a Salesforce-native approach, S-Docs and Portwood DocGen are worth considering. Conga Sign is a natural choice for existing Conga customers, especially those using Conga for CPQ or contract management. Dropbox Sign and signNow can be good options for simpler or more cost-conscious requirements.
When choosing an eSignature app, businesses should look beyond the signature feature. They should also consider Salesforce integration, document generation, Flow automation, APIs, templates, bulk sending, mobile support, document storage, CPQ, contract management, security, pricing, and AppExchange adoption.
The right solution depends on the organization’s business process, Salesforce architecture, security requirements, budget, and expected document volume. A proof of concept can help confirm which solution works best before making a final decision.
