E-signature is the most commoditised category in this directory. Every vendor below captures a legally valid signature with an audit trail; none will fail at the core job. That makes selection unusually pragmatic — the differentiators are what you already own, how deeply the vendor integrates with Dynamics, and whether you need document generation alongside signature.
That last point is where the vendors genuinely diverge. Some are signature tools; others are proposal and document-generation platforms with signature included, which matters if your sales team assembles quotes from Dynamics data. Buying a proposal platform when you only need signature, or vice versa, is the recurring mismatch here.
Does Dynamics 365 include e-signature?
No. Dynamics 365 generates documents from records — quotes, order confirmations, purchase orders — through its own reporting and templates, and stores files against records via the SharePoint integration. What it does not provide is signature capture with the authentication, tamper-evident sealing and audit certificate that make an electronic signature legally defensible. E-signature vendors supply that layer and return the executed document to the Dynamics record, so the sales or procurement process completes without anyone handling files manually.
