Chile has run mandatory electronic invoicing since 2014, longer than most of its neighbors. That maturity is an advantage, but it also means the SII's requirements have layered up over a decade — and companies rolling out Business Central Chile today inherit all of it at once.
Three acronyms carry most of the weight: DTE, CAF, and TED. Getting them straight is the fastest way to understand how the whole system fits together.
How Chile's DTE Model Works
Every invoice, credit note, debit note, or dispatch guide is issued as a Documento Tributario Electrónico (DTE) to the Servicio de Impuestos Internos (SII). Before issuing any DTE, a company requests a CAF (Código de Autorización de Folios) — a signed range of document numbers the SII authorizes in advance. Each DTE then carries a TED (Timbre Electrónico de Documento), a two-dimensional barcode generated from the document data and the CAF's private key, which lets anyone verify the document against the SII. Run out of folios, and invoicing stops cold until a new CAF is requested.
Resolution 154: New Rules for Dispatch Guides
Starting November 1, 2026, Resolution 154 requires more detailed transport data on invoices and dispatch guides tied to the movement of goods: carrier and vehicle identification, a classified transport type, and a dedicated Registro de Guías de Despacho. Companies moving physical inventory need to review this closely, since it touches sales, inventory, and shipping processes together, not just finance.
Where This Shows Up in Business Central Chile Projects
For implementation teams, a few things come up repeatedly:
- Requesting and monitoring CAF folio ranges before they run out
- Generating the TED correctly for every DTE type, not just invoices
- Certifying as an electronic issuer with the SII before go-live
- Capturing the new transport details Resolution 154 requires for dispatch guides
- Replacing the old physical Libros de Compras y Ventas with their electronic equivalents
- Submitting the monthly F29 declaration with figures that reconcile against the DTEs actually issued
Common Challenges in Chile Implementations
Most issues trace back to a few recurring gaps:
- Running out of CAF folios during a busy sales period, which halts invoicing outright
- Treating dispatch guides as an afterthought instead of part of the core sales-to-shipment flow
- Missing the eight-day window customers have to formally accept or dispute a DTE
- Falling behind on SII resolution updates that quietly change validation rules
- Storing the certificate and CAF private keys insecurely, which the SII treats as a compliance issue in its own right
None of these are unusual for a mature e-invoicing market — but Chile's penalties for non-compliance are unusually steep, up to 500% of the transaction value plus business closure for repeated failures.
Why a Dedicated Localization Matters for Business Central Chile
A proper Chile localization automates CAF folio management, generates the TED for every DTE type, and adapts to SII resolution changes like the new dispatch guide requirements. Built as an extension, it does this without altering Business Central's core — and it keeps folio monitoring running in the background, so nobody finds out about a shortage mid-sale.
How LLB Solutions Supports Business Central Chile
LLB Solutions' for Microsoft Dynamics 365 Business Central covers SII electronic invoicing, tax books, and fiscal reporting — including the transport data changes introduced by Resolution 154 — built as an AppSource-certified extension that tracks SII updates as they roll out.
Final Thoughts
Chile's e-invoicing framework is stable, but it keeps evolving — Resolution 154 is only the latest example. Companies that build folio management, TED generation, and dispatch guide compliance into their Business Central Chile environment from the start spend far less time reacting to SII updates after the fact.
For Microsoft partners, that also means checking existing Chile clients' readiness for Resolution 154 well before its November 2026 effective date, rather than waiting for a support ticket.
