Key points

What the buyer sees

A buyer from Croatia sees the OIB field at checkout. A wrong number stops the order with a text, and for other countries the field disappears.

What the admin gets

On the KPD tab you search for a code and assign it to a category. A code not on the list is not saved.

How much it costs

The base version is free. Pro costs 990 UAH for a one-year licence. A year of updates, technical support and all Pro features.

The trial starts when you ask

A fresh install is the free version, nothing switches on by itself. The “Try Pro for 7 days” button → e-mail → the key right in the window and by e-mail.

One key — a site and a staging copy

Moving the site? Unlink the licence on the old domain and activate it on the new one yourself. A staging copy (staging., dev.) works with the same key and does not take a site slot. For studios — keys for 5 or 25 sites, or unlimited.

Technical requirements

  • WordPress 6.2+, WooCommerce, PHP 7.4+.
  • For Pro: an agreement with moj-eRačun, login, password and software id.
  • EUR only, domestic deals between businesses only.

Full module description

eRačun HR turns the order of a business buyer in Croatia into a structured document: UBL 2.1 under the Croatian specification, a KPD 2025 code on every line, OIB and three-part numbering. The XML is built on your server.

We have not sent a single real document through moj-eRačun. The plugin is not legal or tax advice: agree VAT categories, legal reasons and your internal act with your accountant.

What the buyer sees

A buyer from Croatia sees the OIB field at checkout. A wrong number stops the order with a text, and for other countries the field disappears. An order without an OIB gets no eRačun.

What the admin gets

On the KPD tab you search for a code and assign it to a category. A code not on the list is not saved. On the order a button issues the document or names what is missing. Download the XML or, in Pro, send it and refresh the status.

How it works, step by step

  1. Fill in the seller, OIB, IBAN and series.
  2. Assign KPD codes to categories.
  3. The buyer enters the OIB at checkout.
  4. A button on the order issues the eRačun.
  5. Download the XML or send it in Pro.

Under the hood

  • The XML is kept with the order and does not change after sending.
  • A lost answer does not cause a second send: the outbox is read first.
  • The free version connects to no service.

How to install

  1. Plugins → Add New → Upload Plugin: pick the zip and activate.
  2. WooCommerce → eRačun HR: fill in the seller, OIB, IBAN and series.
  3. KPD tab: assign codes to categories.
  4. Issue a document on a test order and compare the XML.
  5. For Pro: paste the key or start the 7-day trial.

The module is not on wordpress.org yet: the free version and Pro are one archive from this page. Without a key it works as the free version.

Does the plugin pick KPD codes?

No, the choice is yours, and an accountant can help.

Is it for consumers?

No, only for businesses in Croatia. Receipts are covered by a separate module, Fiskalizacija HR.

Can I use it without moj-eRačun?

Yes, in the free version you upload the XML to your intermediary.
