EIS Bridge™ — connect any POS/ERP/Business System to BIR EIS transmission without heavy system source-code changes

One Vendor API. Any POS/ERP/Business System. Async EIS transmission.

Map sales from any POS/ERP/Business System to the Standard Sale Object and POST to EIS Bridge. Immediate accepted / queued response — BIR mapping, signing, transmission, retries, and webhooks run in the background. Merchants still complete EIS CERT and PTT per BIR.

API keys are issued to registered vendors. See Get API Key for onboarding.

Built for POS/ERP/Business System integrations

In ten seconds: map your sale from any POS/ERP/Business System to the Standard Sale Object, POST it to EIS Bridge, and store the returned bridge_transaction_id. Checkout never blocks — transmission is async. Poll status or receive webhooks when BIR acknowledges the invoice. One integration path for every merchant on your platform.
