Slovakia e-invoicing
No Slovakia 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 Slovakia support knows what adding it would involve. The countries Invoicerr does cover are listed in the country directory.
Slovakia's B2G e-invoicing runs through the POS (Pokladničný operačný systém) e-invoice system, submitted via the e Faktúra web portal, under the Finančná správa (Financial Administration).
What supporting Slovakia would involve
| System | POS e-invoice system, submitted through the e Faktúra portal |
| Authority | Finančná správa — Financial Administration |
| Format | A national XML schema. No provider in backend/src/modules/documents/formats/ builds it today. |
| Transmission | POS / e Faktúra. 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.
- B2G e-invoicing cited as mandatory since 2018, with extended requirements from January 2024.
- B2B e-invoicing remains voluntary, with no clearance model in place.
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 Slovakia.
country-policy/data/sk.json— which document actions Slovakia allows. Start here: without this file every action is refused with a 403, naming the country.country-identifiers/data/sk.json— which national identifier a party must carry.tax/tax-systems/data/sk.jsonandvat-rates/data/sk.json— the tax kind, and the rate ladder offered on an invoice line.correction-routes/data/sk.json— all eleven canonical correction routes,unverifiedwhere unresearched, never omitted.b2g-routing/data/sk.json— the channel and format a Slovak public buyer requires.transports/channel-policy/data/sk.json— whether a channel is legally required of a seller established in Slovakia, and from what date.archive/retention/data/sk.json— how long an archived document is kept, and what the duration is counted from.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: POS / e Faktúra 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 Slovakia supported?
Check the open compliance issues first. If there is no issue for Slovakia, open one and name which of the files above you need — a request that names one mechanism is far more actionable than "please add Slovakia".
