English summary
BokaLPFR: software fiscal processor for Windows and macOS.
BokaLPFR is a software local fiscal receipt processor (L-PFR) for the Serbian eFiscalization system, made by BOKA GROUP DOO, Belgrade. It turns the Windows or Mac computer your point-of-sale software (ESIR) already runs on into a complete fiscal device: no extra hardware, just a standard USB smart-card reader and the Tax Administration security element.

Approval status
Both editions are approved by the Tax Administration of the Republic of Serbia and listed in the public registry of approved fiscal device elements: BokaLPFR Windows (IB 1664, decision 000-092-00-00177/2026-0000 of 4. 9. 2026.) and BokaLPFR macOS (IB 1663, decision 000-092-00-00176/2026-0000 of 4. 9. 2026.).
Each edition is registered as a separate fiscal device element with its own IB number and registration code; the code appears in every fiscal response as mrc (9A-0001-UID on Windows, 9B-0001-UID on macOS). Registry: purs.gov.rs, approved fiscal device elements.

What it does
- Works offline: invoices are signed locally on the security element; audit packages are stored on disk and sent to the Tax Administration when the connection returns.
- Automatic internet audit in the background; local audit to a USB or SD medium starts by simply inserting the medium.
- BokaLPFR Monitor dashboard in the system tray (Windows) or menu bar (macOS): service, card, connection and audit status with clear warnings.
- Standard POS-to-SDC v3 local HTTP API: works with every approved ESIR, no SDK, no vendor lock-in.
- Security by design: the PIN is never stored, private keys never leave the card, all packages are AES-256 encrypted.
- Safe updates: the installer never touches fiscal data; you decide when to update.
For POS and ESIR integrators
The API is the standard Tax Administration POS-to-SDC v3 protocol served on a local HTTP endpoint, http://127.0.0.1:8443/api/v3/, identical on both editions. Responses are camelCase JSON; status and error codes follow the Tax Administration technical guide.
| Endpoint | Purpose |
|---|---|
| GET /attention | Liveness check; does not touch the card or counters. |
| GET /status | Card, PIN, tax rates and audit state (gsc codes, auditRequired). |
| GET /environment-parameters | Environment parameters from the Tax Administration. |
| POST /pin | Submits the security element PIN; the PIN is never stored. |
| POST /invoices | Fiscalizes an invoice and returns the signed result with journal, QR verification URL and counters. |
| GET /invoices/{requestId} | Recovers the result of an earlier request (idempotent retry). |
The complete integration guide (schemas, invoice types, tax labels, error codebook, examples) is available in Serbian: Tehnički vodič za integraciju (PDF). English support for integrators is available by email.
