BIR EIS · December 2026
The deadline is set.
Is your system ready?
The deadline is fixed. The work to get there isn't automatic. Your systems still need to connect, your invoice data still needs to meet BIR EIS requirements, and your team still needs to know what happens after every submission.
SmartLedger EIS closes that gap by connecting your existing accounting system to BIR EIS, without requiring CAS replacement.
✓No CAS replacement

The path to EIS readiness can start from the accounting environment you already have. SmartLedger EIS is designed to connect that environment to the BIR EIS workflow without requiring CAS replacement.
Your system stays. SmartLedger becomes the bridge.▦

When a submission stops, SmartLedger doesn't.
Failed or interrupted submissions are retried automatically.
Know when something changes.
Get real-time email updates for key submission events and failures.
Leave a trail. Not a question mark.
Keep complete traceability of invoice actions for compliance and audit reviews.
Catch format issues before submission.
Validate invoices against the required BIR EIS standard format before they are sent.
Keep the system that already works.
Integrate with your existing accounting system without requiring CAS replacement.
Not sure where you stand?
Check your EIS readiness first.
Use the separate SmartLedger EIS Readiness Assessment to identify areas that may need attention before implementation.
December 2026 is the deadline.
Not the start of your project.
Integration takes time. Validation takes time. Testing takes time. The deadline isn't the day to discover what still needs fixing.
