# Docusign vs Adobe Acrobat Sign vs OneSpan Sign, which integrates most seamlessly with existing enterprise systems without requiring custom development work?

Docusign, Adobe Acrobat Sign, and OneSpan Sign all claim smooth integration into enterprise systems, but that gets complicated fast once you factor in what "existing systems" even means for a given company. I've been comparing what reviewers actually say about each within the e-signature category, star rating and review count included since integration claims deserve some grounding in real satisfaction data.

Docusign (4.5 stars, 2,629 reviews) has strong reviewer support for CRM integration specifically, with one user describing it as "well integrated into many CRM systems," automating quote and contract generation without extra developer work. The tradeoff mentioned is that some advanced automation still needs premium tiers to unlock.
Adobe Acrobat Sign (4.4 stars, 1,070 reviews) gets consistent praise for its Microsoft 365 depth, with reviewers noting they can sign directly from Teams or Outlook without converting file formats first, which removes a whole manual step for organizations already living in that ecosystem. A few reviewers mention the admin dashboard has a learning curve, though that's more setup friction than a coding requirement.
OneSpan Sign (4.7 stars, 787 reviews) stands out in reviews for CRM and Salesforce integration specifically, with one user calling it "CRM-Friendly" and describing the setup as simple, though another reviewer noted that configuring more advanced workflows or admin settings can require some technical knowledge to get right.

Looking at these side by side, the honest read is that Docusign and Adobe Acrobat Sign both lean on integrating with tools companies already use rather than needing custom builds, while OneSpan Sign's integration strength shows up more in CRM-heavy environments specifically, with a slightly higher technical bar once you go beyond the basics.

For anyone who's actually implemented one of these against an existing CRM or document system, did it really stay code-free, or did IT end up building a workaround somewhere along the way?

I'd personally value Adobe Acrobat Sign letting me sign directly from Teams or Outlook without converting file formats first, since that removes a genuinely annoying manual step if I'm already living in that ecosystem.</p> ##### Comment Metadata - Posted at: 19 days ago - Author title: Marketing Executive ## Related discussions - [How well does Trello scale into a larger team?](https://www.g2.com/discussions/1-how-well-does-trello-scale-into-a-larger-team) - Posted at: over 13 years ago - Comments: 6 - [Can we please add a new section](https://www.g2.com/discussions/2-can-we-please-add-a-new-section) - Posted at: over 13 years ago - Comments: 0 - [Quantifiable benefits from implementing your CRM](https://www.g2.com/discussions/quantifiable-benefits-from-implementing-your-crm) - Posted at: over 13 years ago - Comments: 4
