AGT — Angola e-invoicing
No Angola 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 Angola support knows what adding it would involve. The countries Invoicerr does cover are listed in the country directory.
Angola's e-invoicing is run by AGT, the Administração Geral Tributária, using the OECD SAF-T (Standard Audit File for Tax) standard rather than the clearance-style platforms common elsewhere on the continent. Businesses report through AGT's e-Fatura system.
What supporting Angola would involve
| System | SAF-T / e-Fatura System |
| Authority | AGT — Administração Geral Tributária |
| Format | A national format (SAF-T / e-Fatura). No provider in backend/src/modules/documents/formats/ builds it today. |
| Transmission | Submission to the AGT SAF-T / e-Fatura platform. No transport in backend/src/modules/documents/transports/ talks to it today. |
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.
- SAF-T reporting made mandatory for selected taxpayers from 2019, with ongoing rollout to more businesses.
- Model is structured SAF-T data transmission alongside e-Fatura invoice generation, not a real-time clearance model.
- Digital signature referenced as part of the e-Fatura requirements.
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 Angola.
country-policy/data/ao.json— which document actions Angola allows. Start here: without this file every action is refused with a 403, naming the country.country-identifiers/data/ao.json— which national identifier a party must carry.tax/tax-systems/data/ao.jsonandvat-rates/data/ao.json— the tax kind, and the rate ladder offered on an invoice line.correction-routes/data/ao.json— all eleven canonical correction routes,unverifiedwhere unresearched, never omitted.b2g-routing/data/ao.json— the channel and format an Angolan public buyer requires.transports/channel-policy/data/ao.json— whether a channel is legally required of a seller established in Angola, and from what date.archive/retention/data/ao.json— how long an archived document is kept, and what the duration is counted from.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 AGT SAF-T / e-Fatura platform is a transmission channel this repository does not implement, and its SAF-T/e-Fatura schemas have no format provider. Both are code, not a JSON file — see When a country needs more than a file.
Want Angola supported?
Check the open compliance issues first. If there is no issue for Angola, open one and name which of the files above you need — a request that names one mechanism is far more actionable than "please add Angola".
