Discount engine as a web service (Enterprise)

The discount engine as an external web service makes it possible to standardize promotion calculation methods. This way, other e-commerce applications (ERP system, POS, e-Shop, etc.) can enjoy the benefits of the discount engine. The functionality of the discount engine is adapted to work as a separate web service and calculate discounts on sales document items in the same way regardless of the system.

The discount engine as a web service contains two major modules with dedicated services:

  • Synchronization service
  • Calculation service, including:
    • Discount module
    • Price module

The services can be installed via Comarch Auto Update. Two new components have been added to the Comarch Retail product to support the discount engine:

  • Discount Engine – Discount Service
  • Discount Engine – Synchronization Service

The components can only be installed for the parent agent on the main profile.
