E-Invoicing Delivered As A Service
Advintek’s E-Invoice as a Service provides a managed route for Serbian businesses that need to prepare, process, exchange, and retain electronic invoices through the country’s Electronic Invoice System (SEF).
Instead of building and maintaining the technical connection yourself, you can provide your invoice information to Advintek. Our Invoice Factory platform handles the structured processing layer, including data validation, field mapping, document preparation, electronic submission, available response handling, and invoice archiving.
No repetitive SEF processing. No complex document preparation. No unnecessary technical overhead.

Frequently Asked Questions
What do I need to provide to start Serbia e-invoicing?
You provide relevant invoice information generated through your existing business, accounting, ERP, or billing system. Advintek can then validate, map, structure, and process applicable information through the connected Serbian electronic invoicing workflow, helping align your business data with the requirements of Serbia’s Electronic Invoice System, SEF.
What electronic invoice format does Serbia use?
Serbia’s SEF documentation includes structured electronic invoice specifications and published XML examples based on UBL 2.1. Advintek’s processing workflow is designed to work with applicable Serbian structured invoice requirements, supporting invoice data preparation and document processing according to relevant technical specifications published for Serbia’s electronic invoicing environment.
Do I need to build my own SEF API integration?
Not necessarily. Advintek can provide the technical processing layer between your business system and SEF, reducing the need for your internal team to develop every API connection and document-processing component independently. Serbia publishes official API specifications for direct SEF access, supporting structured electronic document exchange.
Can Advintek handle rejected or unsuccessful invoices?
Advintek’s workflow can provide available processing information and status responses, helping businesses identify invoices requiring attention. Relevant invoice information can then be reviewed, corrected, and processed again where applicable. This gives finance teams greater visibility into document outcomes while supporting continued handling of unsuccessful electronic invoice submissions.
Can invoices be cancelled through the workflow?
Applicable cancellation and storno processes can be supported within the connected workflow, depending on the relevant transaction and SEF processing requirements. Serbia’s published SEF API documentation includes operations relating to invoice cancellation and storno processing, allowing connected systems to manage applicable document actions through the electronic invoicing environment.
Are Serbian electronic invoices archived?
Advintek can maintain processed invoice information and related records within its document-retention environment, giving businesses an organized reference for reconciliation, internal review, and future audit requirements.
