- **Flexible VAT & Tax Engine**: Full support for standard EU/Latvian VAT rates (21%, 12%), 0% VAT, reverse charge mechanisms, and non-taxable transactions in EUR currency.
- **Full Invoice Lifecycle Tracking**: Real-time status management: `Draft` → `Sent` → `Paid` → `Overdue` → `Cancelled`.
- **Customer Directory & Product Catalog**: Reusable client profiles (names, registration numbers, VAT IDs, addresses, bank accounts) and pre-configured service/product items for rapid billing.
- **Developer REST API**: Secure token-authenticated OpenAPI 3.0 REST API for programmatic invoice generation, status checks, and PDF downloads from e-commerce stores, CRMs, and backend services.
