Navigating Integration Complexities with Major ERP Platforms
Regarding the ease of integration with major ERP platforms like Microsoft, Oracle, and SAP, there is no clear leader among these large entities concerning integration design patterns. The integration complexity largely depends on the use of an Enterprise Service Bus (ESB). With an ESB, the ease of integration hinges on how well the ESB can interface with these ERP platforms.
In scenarios without an ESB, assuming there is a team well-versed in the integration layer, the difficulty of integrating with major ERP systems like Microsoft D365, Oracle ERP Cloud, and SAP S/4HANA could be considered comparable, despite the inherent complexities of each ERP system.
However, a significant consideration is the level of customization within these ERP platforms. As the customization increases, the challenge of developing and maintaining integrations also escalates.
Integration Modules
This diagram depicts a high-level integration approach taken by Point of Sale with its partner
systems. 
POS app and CMS send requests to the Point of Sale backend which in turn makes the necessary calls to various systems owned by a merchant and builds the response for the POS app/CMS. Merchants drop product catalog feed files on a secure FTP site, which is then ingested by the Point of Sale cloud.
- Ecomm - Cart and checkout operations
- Payment Gateway - For payment authorization
- CRM - Retrieve customer account details i.e. login, profile cards, profile addresses
- Loyalty - Retrieve customer loyalty details i.e. points, rewards
Besides these high-level blocks, the Point of Sale platform also integrates with other services like gift card authorization, address verification, and more.
