K-OS Billing - 2026 Pricing, Features, Reviews & Alternatives

K-OS Billing by Kavena Consulting automates invoice processing for small and medium enterprises and advisory firms across Spain and Europe. Deployed as part of the proprietary K-OS ecosystem built on cloud native architecture, the solution enables auditability and licensing under each client’s name. The module centralizes repetitive accounting tasks and connects directly to the Spanish Tax Agency through VeriFactu integration.

The system accepts invoices via PDF upload, photograph capture or email ingestion and processes up to eighteen documents concurrently. An artificial intelligence engine performs optical character recognition, transaction classification, chain signature generation in compliance with Royal Decree one thousand seven slash two thousand twenty three and bank reconciliation. The platform monitors tax obligations continuously and highlights irregularities in real time.

A centralized dashboard provides visibility into processed transactions and pending items for review. The three-step workflow comprises document submission, automated processing and user oversight, thereby reducing manual intervention to a final review stage. Integration capabilities support connections to existing enterprise resource planning and customer relationship management systems without requiring full data migration.

Traceability is maintained from original documents through data conversion to decision execution, ensuring a complete audit trail. Kavena Consulting applies a structured implementation methodology that includes process audit, workflow redesign, system deployment, operational handoff and ongoing evolution based on adoption metrics at thirty, sixty and ninety day intervals. The solution addresses forthcoming electronic invoicing mandates for business-to-business transactions and aligns with current regulatory standards.
