Electronic contract signing in the same deal flow
Nango Sign closes the loop: send the contract or annex, signers open the portal, you keep the signed PDF and evidence — native AES; QES via a QTSP partner on eligible plans.

AES and QES in short
The default path in Nango Sign is advanced electronic signature (AES), aligned with eIDAS Art. 26 — suitable for many private B2B contracts.
Where the subscription and platform enable the module, Nango can also orchestrate a QES flow via a qualified trust service provider (QTSP). Nango is not a QTSP — the qualified certificate stays with the partner.
Why “same flow” matters
Signing is not a separate tool you forget after exporting a PDF. The signed document stays tied to the client and contract in Nango, with audit events useful for control.

Eligibility and responsibility
Which signature form a given act requires is for your counsel to decide. Nango orchestrates the flow and evidence; it does not certify legal eligibility per document.
