Project History
Electronic Billing Service
A compliant, hybrid electronic billing Integration designed to align enterprise operations with the Dominican Republic's electronic invoicing mandates.
The system consists of two core components:
• Local client integration: The system interconnects with the host ERP to capture raw transaction data, compile it into the compliant XML schema, execute local validation, cryptographically sign the document, and upload it to the cloud.
• Cloud middleware service: The system manages the external communication layer, ensuring secure, reliable data exchange and compliance reporting directly with the DGII (internal taxes).
