README

A Craft Commerce 5 plugin that sends completed orders to e-računi.hr as invoices: fiscalisation (F1), VAT treatment, KPD codes, and AS4/FINA e-invoice delivery.

What it does

When a Commerce order reaches a configured status (and is optionally fully paid), the plugin builds an e-računi invoice from the order — buyer, line items, VAT treatment, payment method — and sends it through the e-računi REST API. The resulting document (invoice number, PDF, VAT treatment, delivery status) is stored locally and surfaced:

• on the order edit page, as a read-only panel with a manual "Send to e-računi" / "Preview payload" action;
• under e-Računi → Documents in the control panel, a filterable list of every document with a retry action for failed sends;
• to Twig, via craft.commerceEracuni;
• to the console, via craft commerce-eracuni/sync/* commands for status checks, manual sends, backfilling, retries, and delivery-status polling.

The plugin decides, per order, whether the invoice is B2C, domestic B2B, EU B2B (reverse charge), EU B2C, or third-country B2B/B2C, and whether it needs fiscalisation, based on the payment method and the buyer's billing country/organisation/tax ID.

Requirements

• Craft CMS ^5.3
• Craft Commerce ^5.0
• PHP ^8.2
• An e-računi.hr account with API access enabled

Installation

composer require wmd/craft-commerce-eracuni
craft plugin/install commerce-eracuni

Configuration

Connection (.env)

The Connection settings tab is built with suggestEnvVars, so every field can hold an environment variable reference ($VAR_NAME) instead of a literal value. Add these to your .env:

ERACUNI_API_URL=https://e-racuni.com/H7i/API-CLI
ERACUNI_USERNAME=[e-mail]
ERACUNI_TOKEN=your-token-secretkey
ERACUNI_BUSINESS_UNIT=your-poslovna-jedinica-code

Then, in Settings → e-Računi → Connection, set:

Field	Value
API URL	$ERACUNI_API_URL
Username	$ERACUNI_USERNAME
Auth token	$ERACUNI_TOKEN
Business unit	$ERACUNI_BUSINESS_UNIT

Also set the numeric cash register code (naplatni uređaj) used for fiscalised invoices, an optional partner-code prefix for B2C partners (e.g. WEB → WEB-123), and the seller country (only HR is validated in this version). Use Test connection on the same tab to verify the credentials against the e-računi API before enabling auto-send.

Settings tabs

• Connection — API URL, username, auth token, business unit, cash register code, partner code prefix, seller country.
• Documents — auto-send on/off, which order statuses trigger a send, whether the order must be fully paid first, invoice date source (date of sending vs. order date), payment due days, and whether to record a payment on the e-računi invoice for orders already paid.
• VAT — the known VAT rates, the tax rate map and the default VAT rate (below), plus a read-only explanation of how VAT treatment is decided.
• Payments — the payment-method mapping table (below), per Commerce gateway.
• KPD — the KPD field handle and defaults (below).
• Delivery — AS4/FINA delivery toggles, the B2G buyer OIB list, and the cron reminder for delivery-status polling.

VAT rates

Line VAT rates are derived from Commerce's own tax adjustments: the plugin divides the line's tax by its net amount and snaps the result to the nearest of the Known VAT rates (comma-separated, default 25,13,5,0). The shipping line takes its rate from the order-level tax adjustment, not from the first line, so a mixed-rate basket does not deliver at the reduced rate.

Two settings cover the case where Commerce reports no tax at all for a line — no tax engine configured, or a tax rule that does not match:

• Tax rate map — Commerce tax category handle to VAT percentage, e.g. books to 5. Consulted only when the line carries no tax adjustment.
• Default VAT rate — used when the line's tax category is not in the map (default 25).

In both cases the line's Commerce price is read as VAT-inclusive (gross) and the net is derived from it. A domestic invoice line that still ends up at 0% is flagged as a warning in the preview and on the document record, because that is nearly always a missing tax rule rather than a genuine exemption.

Payment method mapping

Each Commerce gateway is mapped to an e-računi payment method, whether it fiscalises the invoice, and the payment method recorded against the invoice. New gateways get a suggested mapping (based on their handle/class name) that you confirm and save on the Payments settings tab; the mapping itself lives in src/core/PaymentMethodMap.php.

e-računi method	Fiscalised	Payment record method
Cash	Yes	Cash
Visa	Yes	Card
EurocardMastercard	Yes	Card
Diners	Yes	Card
Amex	Yes	Card
Stripe	Yes	Stripe
PayPal	Yes	PayPal
CorvusPay	Yes	CorvusPay
KeksPay	Yes	KeksPay
BankTransfer	No	BankPaymentOrder
Compensation	No	Compensation
Other	No	BankPaymentOrder

Fiscalised methods (cash, cards, online wallets) produce an F1 fiscal invoice; bank transfer does not. Zero-total orders (e.g. fully discounted) use "Other". A gateway with no explicit mapping falls back to BankTransfer.

KPD field setup

e-računi line items carry a KPD (Klasifikacija proizvoda po djelatnostima) code. The plugin reads it from:

1. a Plain Text field on the variant or product — the handle is configurable on the KPD settings tab, defaulting to kpd;
2. falling back to a per-product-type default, also set on that tab;
3. falling back to a single global default KPD.

Create the kpd Plain Text field (or whatever handle you configure) on your product/variant field layouts before enabling auto-send, and fill in per-product-type or global defaults for products that don't carry their own code.

Shipping lines use a separate Shipping KPD setting, defaulting to 532000 (postal and courier activities). That default is a suggestion only — confirm the correct code with your accountant before relying on it.

Delivery (AS4 / FINA)

• Deliver B2B invoices over AS4 — sends B2B e-invoices through the AS4 network (on by default).
• Deliver B2G invoices over FINA — sends invoices to public-sector buyers through FINA.
• B2G buyers (OIB) — list of buyer OIBs treated as public-sector (FINA) regardless of the organisation field.

Delivery status (AS4/FINA) isn't known synchronously at send time — poll for it with the sync/delivery-status console command. Add it to cron:

*/15 * * * * php craft commerce-eracuni/sync/delivery-status

(adjust the php/craft paths for your server; see the polling rate-limit note in src/services/DeliverySync.php — one status read per second per batch.)

Console commands

All commands are under commerce-eracuni/sync/:

• craft commerce-eracuni/sync/status — connection check plus a count of documents by status.
• craft commerce-eracuni/sync/order <idOrNumber> — send one order synchronously, under the send mutex; accepts an order ID, number, or reference.
• craft commerce-eracuni/sync/backfill [--dry-run] [--limit=50] [--since=YYYY-MM-DD] — queues every completed order matching the trigger conditions that has no document yet (e.g. orders placed before the plugin was installed).
• craft commerce-eracuni/sync/retry [--all] [--limit=50] — re-queues failed documents.
• craft commerce-eracuni/sync/delivery-status [--limit=100] — refreshes pending AS4/FINA delivery statuses; this is the one to run from cron.

Twig usage

{% set doc = craft.commerceEracuni.documentForOrder(order) %}
{% if doc and doc.isSent() %}
    Račun {{ doc.number }} — <a href="{{ doc.pdfUrl }}">PDF</a>
{% endif %}

documentForOrder() accepts either a craft\commerce\elements\Order or a raw order ID, and returns a wmd\commerceeracuni\models\Document (or null if nothing has been sent yet) with number, status, treatment, deliveryStatus, pdfUrl, and isSent().

PDF links are CP-only in 1.0. Document::getPdfUrl() returns a control-panel action URL (commerce-eracuni/documents/pdf) gated by the plugin's manage-documents permission — it is not a signed or tokenised URL, and the PDF itself never lives under the web root. The link only works for a logged-in CP user with the "Send, preview and retry e-računi documents" permission; there is no public front-end download route in this version.

Legal notes

• Fiscalisation (the F1 fiscal invoice, cash register code, etc.) applies only to cash-like payment methods (cash, cards, online wallets) per Croatian fiscalisation law — not to bank transfers or other non-cash settlement.
• B2B e-invoicing over the AS4 network is mandatory in Croatia from 1 January 2026 for business-to-business transactions. The Deliver B2B invoices over AS4 setting is on by default for this reason.
• B2G (business-to-government) e-invoicing goes through FINA, not AS4. Configure buyer OIBs that should be treated as public-sector on the Delivery settings tab.

None of the above is legal or tax advice — confirm applicability (especially KPD codes and the fiscalisation/VAT treatment split) with your accountant before relying on it in production.

Lineage

The VAT-treatment, fiscalisation, payment-method mapping, and KPD rules in this plugin are ported from WMD's production e-računi integration (invoice_api_eracuni_rest.php in mojwmd), which has issued 3000+ invoices through the same e-računi API.
