Licence terms

1. Parties and subject matter

The licence is granted by Boris Stiner, Aarestrasse 32, 3600 Thun, Switzerland ("Licensor"). The subject matter is the software package stboris-pro/eracun-pro and its documentation ("Software").

Purchase and billing are handled by Polar Software, Inc. as merchant of record. Polar's terms govern payment, invoicing, VAT and refunds. These Terms govern use of the Software.

2. Business customers only

The Software is offered and licensed exclusively to business entities - legal persons, sole traders and persons acquiring it in the course of their trade or profession. It is not intended for consumers within the meaning of consumer protection law and is not sold to consumers.

By purchasing you confirm that you are acquiring the Software for business purposes.

At checkout, tick "I'm purchasing as a business" and enter your VAT or company tax number. The invoice is then issued to the company and VAT is applied under the rules for business customers. If you do not, the purchase is still treated as a business purchase under this clause, but the invoice may not suit your bookkeeping.

3. Scope of the licence

Pro: a non-exclusive, non-transferable right to use, modify and deploy the Software in the projects of one business entity ("Licensed Company"), with no limit on the number of installations, environments or developers within that company.

Agency: everything in the Pro licence, plus the right to embed the Software in products and projects the Licensed Company builds and sells to its clients, with no limit on the number of client projects.

The licence is perpetual and does not end when the update period expires.

4. Restrictions

You may not:

• publish, redistribute, resell or sublicense the source code of the Software, in whole or in substantial part, modified or unmodified;
• make the source code available to anyone outside the Licensed Company, except to clients under the Agency licence and only as part of a delivered product;
• repackage the Software as a competing library, template or starter kit;
• remove copyright notices.

The free package stboris/laravel-eracun is not subject to these Terms and is licensed under MIT.

5. Updates

The licence includes twelve months of access to updates from the date of purchase. After that the Software continues to work indefinitely, but new versions are not included.

The Licensor does not warrant that the Software will be updated within any period following a change to the regulations, the technical specification or the validation artefacts. The Croatian rules change - the Schematron in force since 15 March 2026 is itself a revision published after the obligation took effect. Monitoring the applicable rules and adapting your own systems in good time is the Customer's responsibility.

6. What the Software is not

These boundaries are an essential part of the subject matter, not a later carve-out:

• It does not perform fiscalisation and sends no data to the Tax Administration.
• It does not sign documents and does not handle, store or transmit digital certificates.
• It is not a transmission provider and does not transmit e-invoices. Provider adapters use the Customer's own credentials and contract.
• It connects to no government system.
• It is not a conformance validator. It checks the business rules published in the Croatian Schematron. Passing does not mean a document will be accepted.

The obligation to comply with the Croatian fiscalisation act and related regulations rests by law on the taxpayer and remains solely with the Customer. Using the Software does not transfer that obligation to the Licensor and does not make the Customer compliant.

7. Warranty

The Software is provided "as is". To the extent permitted by the applicable law, all express and implied warranties are excluded, including warranties of fitness for a particular purpose, uninterrupted operation and freedom from defects.

The Licensor does not warrant that a document produced with the Software will be accepted by a transmission provider, the Tax Administration or the invoice recipient.

8. Liability

The Licensor's liability for damages is limited to the amount the Customer paid for the licence.

Liability for indirect and consequential damage, lost profit, lost data, business interruption, administrative and tax penalties, and third-party costs is excluded, on whatever legal basis.

These limitations do not apply to damage caused intentionally or by gross negligence (Art. 100 of the Swiss Code of Obligations), nor to liability that cannot be limited under the applicable law. To that extent liability is determined by statute.

9. Refunds

Refunds are processed by Polar under their terms. Since the free package is a complete document-processing mechanism and available at no cost, you are encouraged to try it before purchasing. On an approved refund, access to the private repository is revoked and the licence ends.

10. Support

Bug reports are accepted at info@eracunpro.com. Contractual response times (SLA) are not part of the licence. The Software is developed alongside other work and a reply may take time.

11. Changes to these Terms

The version of the Terms in force on the day of purchase applies to that purchase. Changes do not apply retroactively to licences already granted.

12. Governing law and jurisdiction

Swiss law applies, excluding its conflict-of-law rules and the UN Convention on Contracts for the International Sale of Goods (CISG). The exclusive place of jurisdiction is Thun, canton of Bern, Switzerland.

If any provision proves invalid, the remainder stays in force and the invalid provision is replaced by one that is legally permissible and closest to its purpose.
