Certyneo × Sellsy — eIDAS electronic signature directly in your French CRM
Signatories automatically added from your Sellsy contacts, documents generated from opportunities, eIDAS audit trail synchronized — without leaving Sellsy. Two sovereign solutions, hosted and edited in France.
Sign up for early access
Be among the first to test Certyneo's Sellsy integration. You'll be notified as soon as beta opens and can co-build workflows with our product team — two French actors side by side.
No commitment. You'll receive an email when beta opens.
What's coming in the Sellsy integration
Here are the features planned for the initial version of the native integration. They will be built in collaboration with early access members. The native integration is in preparation — in the meantime, Zapier, webhooks, and the REST API already work.
Signature events in Sellsy activities
Each Certyneo send, signature, and rejection will automatically create a Sellsy activity on the relevant contact or opportunity, for complete sales tracking without duplicate data entry.
Enriched opportunity timeline
You'll see the signature status (pending, signed, expired) directly in the Sellsy opportunity form, without changing tabs or leaving your sales pipeline.
Convert prospect → contract in one click
From a Sellsy opportunity, you'll generate and send a Certyneo document or contract pre-filled with CRM data in a single click, all the way to the invoice.
Sellsy custom fields
You'll map your Sellsy custom fields to variables in your Certyneo document templates, for contracts and quotes always up to date with CRM data.
The native integration is in preparation. In the meantime, connect Certyneo to Sellsy today via our REST API, webhooks, or Zapier.
