Country deep dive
Chile was one of Latin America's earliest movers on e-invoicing — the system is mature enough that most of today's activity is about extending it (boleta, digital delivery) rather than building it.
Chile's Servicio de Impuestos Internos begins testing electronic tax documents on a voluntary basis with the country's largest taxpayers, ahead of any general mandate.
Structured electronic tax documents become a universal requirement across the Chilean economy — every VAT taxpayer must issue DTEs rather than paper equivalents.
The electronic consumer receipt (used for B2C retail transactions) becomes mandatory economy-wide, issued from point-of-sale systems with SII certification.
Businesses without point-of-sale printing capability must deliver the boleta electrónica digitally — by email, SMS, WhatsApp, QR code, or another equivalent electronic channel — rather than skipping delivery altogether.
Chile's DTE model rests on two pillars: the folio authorisation (CAF) that legitimises your invoice numbers, and the electronic stamp (TED) that makes each document verifiable.
Each DTE type is identified by its own numeric code — get this wrong and the document is processed as the wrong type entirely, not just flagged for review.
Unlike systems where invoice numbering is just an internal convention, Chile's folio numbers are a government-issued resource you draw down from — running out means requesting a new CAF before you can issue anything further.
Without both the TED and the XMLDSig signature, a DTE has no tax validity — these aren't optional integrity add-ons, they're what makes the document legally an invoice at all.
Every DTE must carry a valid RUT for both parties — validate the modulo-11 check digit before submission to catch typos that would otherwise cause rejection.
A DTE only becomes legally valid once SII has validated it — this is a genuine clearance model, not a self-certifying one.
The CAF request happens once per folio range, not per invoice — but every individual DTE still needs its own TED, signature, and SII submission before it's valid.
Because F29 draws directly from your DTE activity, discrepancies between what you've issued/received and what you declare tend to surface automatically — DTE data and VAT filing are tightly coupled in Chile.
Third-party gateways exist specifically to let invoicing software providers request, store, and track CAF folios programmatically rather than through manual SII portal logins.
Retail boletas follow a lighter submission process than full facturas — worth knowing if you're building for high-volume point-of-sale rather than B2B invoicing.
Accreditation as an authorised issuer is a genuine certification process with the SII, not a self-serve signup.
Undergo generation and reception testing with the SII before you're accredited to issue DTEs in production.
Get your firma electrónica from an SII-accredited provider — this is what authenticates every CAF request and signs every DTE.
Apply via the SII web portal or API for each DTE type you'll issue, authenticating with your digital certificate.
Embed the TED electronic stamp and apply the XMLDSig signature before every submission — both are non-negotiable for legal validity.
Validate your full issuance flow before switching to production — most gateways and integrations support a dedicated certification mode for exactly this purpose.
Build automated reconciliation against the SII's pre-populated RCV/F29 declaration, and archive both issued and received DTE XML files for the required retention period.
If you lack point-of-sale printing, set up a digital delivery channel (email, SMS, QR) now rather than after an audit flags the gap.
The sharpest practical risk in Chile isn't the fine itself — it's losing the ability to invoice at all.
