The Solution


The implementation of Comarch Loyalty Management at the Leroy Merlin chain of stores finished in April 2008. The project was accomplished within six months.


The Comarch Loyalty Management system implemented at the Leroy Merlin consists of the Business Administration application, the B2C web application for customers and the application for Customer Service Offices at stores, offering all of the features related to customer registration and bonus redemption. The system was implemented at the Data Center located at Leroy Merlin head office.


The system was implemented on an offline model. Transactional loyalty data is registered in the cash system and, once assigned to the number of the loyalty card, transferred once a day, as part of a single file, to the loyalty system for further processing. Redemption operations are registered on-line in the system
