Features

Everything a fiscal device must do — as an API.

The accreditation checklist, implemented. Where a requirement is genuinely about the till (void, discount, catalog), the Bridge carries the field and a reference connector demonstrates the UI.

Fiscalization core

Synchronous V-SDC signing

Real-time fiscalization with mutual-TLS authentication per shop.

Idempotent exactly-once

Stable 32-hex request id; retries never double-sign.

Two-tier retry

In-process quick retries plus a durable backoff queue for outages.

Verbatim Chapter-8 journal

Stored and rendered byte-for-byte — compliant by construction.

Tax & documents

Tax rates from the SDC only

Synced and validated; unknown labels are rejected.

QR + verification URL

Official QR (GIF) and a URL that resolves on the authority's verifier.

Paper & electronic delivery

Print the receipt or email the journal + QR.

Refunds, copies, proforma, training

Full invoice-type and transaction-type matrix.

Multi-tenant operations

Per-shop credentials

Encrypted PFX, PAC and POS number — onboard hundreds.

Tenant isolation

Every record scoped to its tenant; API keys hashed and revocable.

Test Connection

Validate a certificate live before going live.

Invoice log & audit

Searchable history with journal, QR and retry.

Resilience & security

Offline-safe selling

Interim non-fiscal slip now, fiscal receipt on reconnect.

Encrypted vault

Secrets encrypted at rest; never logged in the clear.

Signed webhooks

HMAC-signed callbacks with durable, retried delivery.

Sandbox guardrail

SSL verification is only relaxed against the sandbox host.
