About us
Fiscalization that web shops don't have to think about
Dark ESIR connects your web shop to the Tax Administration's TaxCore VSDC. You add your location's certificate once, and your shop issues fiscal invoices with a single API request.
We built it because fiscalizing online sales shouldn't mean running a POS in the back office. Signing, retries, refunds, copies and reports are handled for you, with readable values instead of VSDC's numeric codes.
What we care about
Built for Serbian fiscalization
Every invoice type and transaction VSDC supports, Cyrillic or Latin receipts, and reports that match the VSDC journal.
Your certificate stays protected
Certificates, passwords and PACs are encrypted and only decrypted in memory when an invoice is signed.
Made for developers
A small REST API with idempotency keys, clear errors and an OpenAPI specification, plus a dashboard for everyone else.
