iden.pos is a full point-of-sale system certified for Bulgarian NRA Ordinance H-18 fiscal compliance. Direct integration with Datecs FP-700MX fiscal printers via ErpNet.FP middleware, built on a bounded state machine that survives power cuts, printer timeouts and messy real-world conditions.

Architecture

A four-layer fiscal pipeline

iden.pos separates application logic from fiscal hardware via a clean, swappable abstraction. That's what makes it auditable, testable, and ready for production.

Layer 1 · Application
iden.pos terminal & Edge Functions Tabs, shifts, orders, split payments, KDS. Supabase + Deno Edge Functions with postgres.js transactions.
TypeScript
Layer 2 · FAL
Fiscal Abstraction Layer (FAL) Swappable ErpNetFPProvider (production) or MockProvider (tests). Per-tenant fiscal_mode config.
iden-built
Layer 3 · Middleware
ErpNet.FP Open-source REST/JSON fiscal middleware, deployed on local HP EliteDesk or Raspberry Pi hosts per venue.
0BSD
Layer 4 · Hardware
Datecs FP-700MX NRA-certified fiscal printer with secure fiscal memory. 6 units deployed at Area 52 across two venues.
Certified
Compliance

Built for the strictest fiscal regime in Europe.

Bulgarian NRA Ordinance H-18 (Наредба Н-18) is one of the most prescriptive fiscal regulations in the EU. Every receipt must be signed by a certified fiscal device, every cancellation must leave an audit trail, and every POS system must register as a СУПТО (Software for Sales Management) with a designated human guarantor.

iden.pos is built to comply with all of it — not as an afterthought, but as the foundational spec that the rest of the system was built around.

NRA Ordinance H-18 Full compliance with Bulgarian fiscal regulation for cash register software.
Registered СУПТО Software for Sales Management registration with a designated guarantor at Flexcon EOOD.
Appendix 29 reporting Full export of Tables 18.1–18.5 and 18.9 for NRA audits and controls.
UNP (Unique Sales Number) Every transaction gets a deterministic UNP. Duplicate-detection and collision recovery built in.
Storno / reversal handling Proper fiscal reversal workflow with guarded state transitions — no orphaned fiscal states.
EUR currency ready Built primary in EUR following Bulgaria's euro adoption — no legacy BGN-only assumptions.
Capabilities

Everything a busy venue needs, nothing it doesn't

iden.pos is designed for activity venues with mixed service models — session-based, F&B, retail, packages — running side by side.

Tab management

Open, split, merge and transfer tabs with an advisory-lock state machine that prevents race conditions at the counter.

Shift control

X-reports, Z-reports, cash-drawer declarations, and fiscal-day close-out — handled by the FAL layer.

Split payments

Any combination of cash, card, vouchers and loyalty rewards — reconciled cleanly against the fiscal record.

Kitchen Display System

Orders flow to the kitchen in real time. Per-item cancel support for restaurants that need fine-grained control.

Offline-first

Staff tablets keep working when the internet goes out. Orders sync when connectivity returns.

Session products

Time-boxed entry products (60-min jumps, 2-hour sessions) with automatic check-in and revenue recognition.

Audit-ready

Immutable audit log of every fiscal event, every cancellation, every staff override. Designed for NRA inspection.

Row-level security

Multi-tenant isolation at the database level. 25+ RLS policies enforce per-tenant data access.

Devices admin UI

1:1:1 mapping of POS terminal → ErpNet host → fiscal printer. Atomic serial-number changes with graceful handoff.

Hardware

Certified, proven, deployed

iden.pos runs on the hardware that venue operators already trust — and the fiscal devices the NRA already certifies.
