Choose the relevant ecert service
ecert's Chilean product range separates online document signatures from certificates used for electronic invoicing through the Servicio de Impuestos Internos, or SII. That distinction matters when preparing a digital signature: the product needed for a contract is not automatically the product used for a tax filing.
The provider also offers a dedicated service for Tu Empresa en un Día. Its general online advanced-signature products exclude that business-formation process and SII invoicing, so check the purpose of your transaction before arranging a credential.
Prepare for online identity checks
For Firma Electrónica Avanzada Online, ecert describes an online application using ClaveÚnica and a valid identity card. The official site also identifies ecert Verify as part of identity verification for its online advanced-signature service. These preparations concern the provider's credential and identity process.
ecert has a separate single-use advanced-signature option, obtained through ClaveÚnica verification. Keep the distinction between a reusable online signing service and a signature for one use when following the method configured for your document.
Sign the document through Nota Sign
Open the document in Nota Sign, review it and complete the required fields. Continue with the configured ecert method and carry out the identity checks and signature authorization requested for that method. Then complete the signing workflow in Nota Sign.
The exact ecert service selected for the transaction determines which provider preparations apply. The document journey remains in Nota Sign, while ecert supplies the relevant certificate and signing process.
Understand the Chilean terminology
Firma Electrónica Avanzada is the provider's Chilean product terminology. It should retain that local context when discussing electronic signatures rather than being automatically relabeled as EU QES. ecert's official product information explains its online signatures, tax certificates and other transaction-specific services.
