The Philippine compliance context
The BIR EIS mandate under the TRAIN Law — what it means for your business.
Revenue Regulation No. 11-2025 (RR 11-2025), issued under the Tax Reform for Acceleration and Inclusion (TRAIN) Law, requires covered Philippine taxpayers to transmit electronic invoices directly to the Bureau of Internal Revenue Electronic Invoicing System (BIR EIS). The obligation covers electronic invoice issuance under Section 237 of the NIRC, with mandatory live transmission required by December 31, 2026.
Your business should not have to rebuild its invoicing operation to meet the BIR EIS deadline. BIREIS helps you connect the systems you already use, prepare your invoice data, manage the transmission workflow, and keep the evidence your finance team needs from assessment through go-live.

Who we serve
One controlled path for every team in the Philippine invoice chain.
Whether you issue invoices, operate source systems for clients, or manage transaction flow at scale — the Exchange gives your team a clear compliance operating model.
Enterprise finance teams
Large source estates mean more mapping complexity, more failure modes, and more audit exposure. The Exchange gives you a single reconciliation point across all your source systems — with a full audit trail for every BIR submission.
ERP, POS, and CAS builders
Your customers are asking if your system supports BIR EIS. Integrate once into the Exchange and answer yes — without building a compliance layer into every product release or maintaining your own BIR authority connector.
High-volume operators
Designed for sustained BIR submission flow with idempotency, durable queues, retry policies, and operational evidence — so high invoice volumes do not become audit liabilities or reconciliation backlogs.
A clear path
From your source system to BIR EIS — every step controlled.
Every integration follows a visible path: normalize, validate, transmit to the BIR EIS, reconcile the authority response, and retain the evidence required under applicable Philippine electronic-invoicing regulations.

The exchange
Get your business ready for BIR EIS with one managed connection.
Keep your ERP, POS, CAS, and finance workflows in place. BIREIS gives your team one clear path to connect, validate, transmit, and reconcile every invoice as you move toward go-live.
01 / Normalize
One model for every source.
Adapters translate SAP, QuickBooks, POS, CAS, batch files, and custom applications into a validated, BIR-ready invoice model — without changing your source system.
Canonical data model02 / Control
Every BIR submission has a state.
Idempotency, validation, durable queues, retry policy, and evidence make every BIR EIS outcome explainable — even when the authority returns an error.
Submission state machine03 / Operate
See every BIR submission, clearly.
Reconciliation, evidence, usage, and operations views give your finance and compliance teams the context to resolve exceptions quickly and demonstrate BIR audit readiness.
Operational evidenceBuild vs. integrate
Why the Exchange — not a custom BIR connector?
Most teams underestimate the ongoing complexity of building and maintaining a direct BIR EIS integration. The Exchange is designed specifically for that complexity.
Custom in-house build
BIREIS Exchange
One integration per source system — SAP, POS, and CAS each need their own connector
One canonical model covers all source systems through a single boundary
BIR authority session management, retry logic, and inquiry flow built from scratch
BIR EIS authority connector — session, encryption, retry, and inquiry — already handled
No durable evidence ledger without additional engineering investment
Audit-ready evidence records retained for every BIR submission and response
Every source-system upgrade risks breaking the BIR connector
Source-system changes stay isolated at the adapter edge — the BIR path stays stable
Multi-entity businesses need separate connectors per entity with separate credential management
Designed from the start for multiple entities — separate credentials, data, and evidence per entity
Digilabs is pursuing BIR ESP accreditation so businesses can work with one accountable technology partner for their BIR EIS rollout. BIREIS is built to connect your existing systems, validate and transmit invoice data, preserve submission evidence, and support reconciliation. We help your team move from integration assessment to testing and go-live with a managed, business-ready path.
Integrations
Your existing systems connect — as-is.
SAP, QuickBooks, local CAS, POS, or a fully custom system — it doesn't matter. The Exchange is ERP-agnostic by design, providing a consistent integration boundary to the BIR EIS without forcing you onto a specific platform or rebuilding your source systems.
Not on SAP? Good — most Philippine businesses aren't. BIREIS was built for the full range of systems Philippine businesses actually use.

04Operate
Go live with monitoring, reconciliation, and a clear path for BIR exception handling and audit evidence — supported by a Philippine-based team that knows the BIR process.
Common questions
Start with the questions that matter.
What is the BIR EIS mandate?
The Bureau of Internal Revenue requires covered Philippine taxpayers to issue and transmit electronic invoices directly to the BIR Electronic Invoicing System (EIS) under the TRAIN Law (RA 10963) and its implementing Revenue Regulations. Section 237 of the NIRC governs electronic invoice issuance; the mandatory live transmission deadline is December 31, 2026.
Which taxpayers are covered by the December 31, 2026 deadline?
The obligation applies to covered taxpayers designated by the BIR under applicable Revenue Regulations. Your tax counsel, BIR-accredited ESP, or BIR District Office can confirm your specific classification and coverage. BIREIS provides the integration path once your BIR EIS Certification is in place.
What happens if a BIR submission fails?
The Exchange separates intake from BIR delivery. A failure at the BIR authority layer does not lose the invoice — it remains in a durable outbox, retried with exponential backoff, with the failure reason and all retry attempts recorded in the evidence ledger. Your operations team can monitor status and trigger manual review if needed.
How long does integration typically take?
Timeline depends on your source system complexity, the number of invoice types, and BIR authority credential readiness. The engagement model is structured (Understand → Configure → Prove → Operate) so you have a clear milestone path from first assessment to BIR EIS go-live. Contact us with your systems and target date for a more specific view.
What systems can connect?
Enterprise ERP (SAP, Oracle, NetSuite), local CAS, POS, batch file sources, and custom applications can connect through the integration boundary via REST API, SDKs, or file-based adapters.
Is this only for SAP?
No. The Exchange is source-system agnostic — the canonical invoice model and BIR authority connector are the same regardless of which system submits the invoice. SAP, QuickBooks, local CAS, POS, and custom applications all use the same controlled workflow.
Why choose BIREIS for your BIR EIS rollout?
Digilabs is pursuing BIR ESP accreditation and is building BIREIS for businesses that need a practical, managed path to BIR EIS readiness. We connect your ERP, POS, CAS, or custom application; validate invoice data; manage transmission workflow; retain evidence; and support reconciliation. Start with an assessment so we can map your systems, volume, branches, and go-live path.
Can high-volume invoice transactions be supported?
The architecture is designed around durable intake, idempotency, queues, per-tenant rate limiting aligned to BIR authority constraints, and operational evidence — specifically for high-volume production use cases. Contact us with your estimated daily or monthly invoice volume for a systems-sizing discussion.
