How Croatia e-Invoicing Runs Through Sage 300

  • Capturing the Posting Immediately: As soon as an invoice posts in Sage 300’s Accounts Receivable module, Advintek retrieves it directly.
  • Running the Porezna Uprava Check: The invoice sits in Advintek’s review queue, measured against Croatia’s fiscalisation rules.
  • Converting to Compliant XML: Sage 300’s output is transformed into the required structured XML format, ensuring accurate invoice presentation and preventing layout-related issues across every company database. 
  • Sending It Through a Traceable Lane: The invoice moves through a permissioned, fully logged channel toward submission.
  • Reporting to Porezna Uprava in Real Time: Filing goes out via approved transmission routes, consistent across companies and cross-border customers.
  • Archiving for Years: Cleared invoices are stored to Croatia’s retention standard, ready whenever an audit requires them.

What is Advintek's Croatia e-Invoice Connector for Sage 300?

Sage 300 creates invoices through order entry, project billing, and job-costing modules operating across multiple companies and currencies. Advintek converts those records into compliant formats, routes them through connected Peppol channels, and tracks fiscalization responses while keeping Sage 300’s multi-entity configuration unchanged.

Frequently Asked Questions Sage 300 e-Invoicing Croatia

Does Sage 300 handle Porezna uprava's requirements on its own?

No. Sage 300 has no native connection to Porezna uprava’s fiscalisation and e-reporting systems, so a connector like Advintek is still needed.

It draws transaction data from Sage 300 and routes it through Advintek for XML conversion, validation, and submission to Porezna uprava.

No. Financial workflows stay the same — Advintek handles the formatting, checking, and filing behind the scenes.

No. Advintek converts and presents figures the way Porezna uprava requires at fiscalisation.

Yes. Advintek connects to Sage 300 directly, so filing works the same regardless of which company database raised the invoice.
