Implementation Journey
Five steps to full BIR compliance.
Step 01
Free Compliance Assessment
Our compliance team evaluates whether your business is covered under RR 011-2025, identifies any gaps in your current setup, and recommends the right 1nvoice configuration.
Step 02
System Setup & Configuration
We configure 1nvoice for your business — tax rules, invoice templates, user roles, and workflow settings. Cloud or on-premise deployment based on your preference.
Step 03
Integration with Your Existing Systems
Our middleware layer connects 1nvoice to your existing SAP, Oracle, NetSuite, Microsoft, or other ERP/POS system. Zero disruption to your ongoing operations.
Step 04
Training & Go-Live
We train your team — finance, tax, and admin staff — on using 1nvoice. Once trained, your system goes live and begins transmitting to the BIR EIS Portal automatically.
Step 05
Ongoing Support & Regulatory Updates
As BIR regulations evolve, your 1nvoice system is updated automatically. Our support team is always available for troubleshooting, performance monitoring, and audit preparation.
