MH — El Salvador e-invoicing

Invoicerr does not support El Salvador

No El Salvador data file exists anywhere in this repository — no country policy, no identifiers, no tax system, no transmission channel. Nothing on this page is implemented. It is here so that someone who wants El Salvador support knows what adding it would involve. The countries Invoicerr does cover are listed in the country directory.

El Salvador's e-invoicing (factura electrónica) runs through the Ministerio de Hacienda, which pre-authorizes every DTE document before it can be delivered to the buyer.

What supporting El Salvador would involve​

SystemDTE — Documento Tributario Electrónico (Ministerio de Hacienda)
AuthorityMH — Ministerio de Hacienda
FormatA national XML schema (the MH DTE schema). No provider in backend/src/modules/documents/formats/ builds it today.
TransmissionSubmission to the Ministerio de Hacienda platform for authorization. No transport in backend/src/modules/documents/transports/ talks to it today.
Inherited, unverified

Carried over from an earlier research pass in this repository's own history, and never checked against a primary source. Leads, not facts — confirm every line before writing it into a data file.

  • Progressive rollout, mandatory for all businesses.
  • Digital certificate and sequential numbering required.

Which catalogues a contributor would add​

Adding a country is data, not code. Adding a country is the procedure and the contract each file has to satisfy; this is only the shopping list for El Salvador.

  • country-policy/data/sv.json — which document actions El Salvador allows. Start here: without this file every action is refused with a 403, naming the country.
  • country-identifiers/data/sv.json — which national identifier a party must carry.
  • tax/tax-systems/data/sv.json and vat-rates/data/sv.json — the tax kind, and the rate ladder offered on an invoice line.
  • correction-routes/data/sv.json — all eleven canonical correction routes, unverified where unresearched, never omitted.
  • b2g-routing/data/sv.json — the channel and format a Salvadoran public buyer requires.
  • transports/channel-policy/data/sv.json — whether a channel is legally required of a seller established in El Salvador, and from what date.
  • archive/retention/data/sv.json — how long an archived document is kept, and what the duration is counted from.

Add mentions/, content-requirements/, country-fields/, reporting/ and domestic-reverse-charge/ only where the law actually gives them content.

Data alone will not finish the job here: the Ministerio de Hacienda platform is a transmission channel this repository does not implement, and its XML schema has no format provider. Both are code, not a JSON file — see When a country needs more than a file.

Want El Salvador supported?​

Check the open compliance issues first. If there is no issue for El Salvador, open one and name which of the files above you need — a request that names one mechanism is far more actionable than "please add El Salvador".
