PROZORRO — Ukraine e-invoicing

Invoicerr does not support Ukraine

No Ukraine 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 Ukraine support knows what adding it would involve. The countries Invoicerr does cover are listed in the country directory.

Ukraine runs two parallel systems: PROZORRO for public procurement e-invoicing, and a separate general Tax Authority system for B2B, both under the State Tax Service (DPS).

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.

  • PROZORRO cited as mandatory for public procurement since 2016.
  • B2B e-invoicing described as progressive, with requirements extended in 2023 and 2024.
  • The two systems are described as running in parallel rather than as one unified platform.

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 Ukraine.

  • country-policy/data/ua.json — which document actions Ukraine allows. Start here: without this file every action is refused with a 403, naming the country.
  • country-identifiers/data/ua.json — which national identifier a party must carry.
  • tax/tax-systems/data/ua.json and vat-rates/data/ua.json — the tax kind, and the rate ladder offered on an invoice line.
  • correction-routes/data/ua.json — all eleven canonical correction routes, unverified where unresearched, never omitted.
  • b2g-routing/data/ua.json — the channel and format a Ukrainian public buyer requires.
  • transports/channel-policy/data/ua.json — whether a channel is legally required of a seller established in Ukraine, and from what date.
  • archive/retention/data/ua.json — how long an archived document is kept, and what the duration is counted from.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: PROZORRO and the Tax Authority system are transmission channels this repository does not implement, and neither's XML schema has a format provider. Both are code, not a JSON file — see When a country needs more than a file.

Want Ukraine supported?​

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