Sandbox VS Production

Billit provides two distinct environments tailored for developers.

  • Production - connected to live accounting data and e-invoicing networks. Use this environment only for real business operations.
  • Sandbox - a safe replica of the production setup, designed for testing. Sandbox traffic reaches test government entities or test e-invoice networks, making it ideal for integration testing and experimentation.

By separating these environments, developers can test safely while ensuring compliance and data integrity in production.
