Ready-made Sender UI, not just an API
Most e-sign APIs give you signing functionality, then leave your team to build the sender interface: signer forms, signing order, invitations, reminders and status tracking. That work is slow, expensive and easy to underestimate.
Docue ships the Sender UI as an embeddable module. Your customers can manage the full signing workflow out of the box, while your team keeps the integration focused and the user experience polished.
Faster time to market
Skip months of custom sender UI development. Embed, configure and launch with a proven workflow.
Customers in control
Let end customers add signers, set signing order, send invitations and track progress inside your platform.
Your brand first
Match the look and feel of your product so users do not feel pushed into a separate signing application.
Three ways to strengthen your business case
Launch e-signing as a focused feature, or make it part of a broader legal workflow that creates new value inside your platform.
Sign documents your platform creates
Any document your platform generates — leasing agreements, financing contracts, service agreements — is ready to send for signature without the customer ever leaving your product.
Sign your customers' own documents
Let end customers upload any document and manage signers, order and reminders from the same embedded workflow.
Pair with Embedded Legal Engine
Combine drafting, negotiation and signing into one in-platform legal journey when customers need more than signatures.
