## Core Product Ecosystem

### 1. CittaEFS — Electronic Fiscal Middleware
CittaEFS acts as a non-intrusive compliance bridge between enterprise ERPs (SAP, Oracle, Odoo, Microsoft Dynamics, Infor, custom accounting software) and statutory government tax authority portals (such as the National Revenue Service / NRS).

- **How It Works:**
  1. An invoice or billing entry is created in the host ERP.
  2. CittaEFS intercepts the transaction at the database trigger or API layer in real time.
  3. CittaEFS validates calculation rules (e.g., standard 7.5% Nigerian VAT, exempt items, withholding tax logic, TIN format verification).
  4. Once pre-cleared, CittaEFS cryptographically signs the record and transmits it directly to the statutory authority portal.
  5. The official QR code / clearance stamp is returned and embedded into the ERP invoice before dispatch to the customer.
- **Key Advantages:**
  - Zero modification to existing accounting workflows.
  - Automatic error isolation: invalid tax calculations are flagged immediately in a local queue rather than failing silently at government submission.
  - Native support for Odoo ERP, SAP S/4HANA, and custom SQL ledgers.
