Electronic signatures and agreement workflows built into Dropbox
Recipients can review and sign agreements securely without creating an account, which removes friction from external signing.
Prepare NDAs, offer letters and contracts once, then reuse them for future requests to save time on recurring paperwork.
Embed secure, branded eSignature flows directly into your website, app or customer experience with a dedicated API.
Completed agreements are saved automatically to your preferred storage account so nothing gets lost in inboxes.

AI agents that run document-heavy business processes end to end
Agents read invoices, POs, remittances, claims and forms, then act on them — matching, approving and posting rather than only extracting fields.
Clean, validated data is written directly into systems of record including SAP, Salesforce, NetSuite, QuickBooks and Gmail workflows.
Policies, SOPs, system data and conversation history are stored as a governed graph so every agent decision cites the rule and document behind it.
Prebuilt flows for accounts payable, reconciliation, order management, cash application, supplier onboarding and claims processing.
