Horizontal Monitoring Platform
Introducing b2g.az: Horizontal Monitoring Data Exchange for Azerbaijan

Horizontal Monitoring (Üfüqi monitorinq) replaces routine desk and field audits with continuous, structured information exchange between the taxpayer and the State Tax Service (DVX). To stay in the program, companies must place tax and accounting data on an electronic platform and grant DVX access — without giving up control of their financial systems.
b2g.az is DECLAVA’s dedicated platform for that requirement.
Each taxpayer gets an isolated instance on their own company server, published at https://{voen}.b2g.az. Financial data stays on premises. DVX works in a clear Azerbaijani workspace with drill-down from summary reports to supporting documents.
Why companies choose b2g.az
- Data residency — Tax and accounting data remain on the company’s server; DECLAVA operates DNS and the product, not your ledger.
- DVX-ready workspace — Navigation tree, completeness/coverage status, last update time, and Azerbaijani UI aligned with DVX technical expectations.
- 4-level drill-down — Reports → registers → journals/transactions → supporting documents and files.
- ERP-agnostic ingest — SAP, 1C, or custom ERP map into one Standard Format v1 via a client-side transform; core product has no ERP lock-in.
- Reconciliation & quality gates — Server-side validation and cross-level checks before data is accepted.
- Period lock & version history — Lock periods after sign-off; keep immutable snapshots and amendment history.
- Audit & security — Append-only audit log, HTTPS, 2FA, role-based access, export with watermarks (XLS/PDF).
- Retention — Designed for multi-year retention (minimum 5 years per requirements).
How it works
- Deploy the tenant stack on the company server (Docker Compose / Coolify).
- Connect your ERP with a transform script that posts Standard Format v1 to API
- Grant access — company admins create DVX user accounts on your
{voen}.b2g.azinstance. - Monitor & respond — DVX reviews data, runs queries (sorğu-cavab), and exports; your team tracks sync status and completeness.
