Publicat
E-shop of one of the largest publishing houses
About Publicat eCommerce and our implementation
When designing and implementing an online store for a leading Polish publishing house, we had to meet our client’s expectations. The Publicat Group owns numerous thematic publications, and the platform was intended to showcase the Group’s strengths while also serving as a user-friendly shopping tool.

Consulting work, technological assumptions and key functionalities
Description of functionality:
- An extensive book catalog, divided by department, publisher, and author.
- A central product data warehouse for several thematic websites (automatic catalog data integration).
- A discount code system.

Pre-implementation documentation
After completing the initial documentation, we conducted a graphic design process for the system and mobile app. This resulted in over 60 unique views ready for implementation, known as high-fidelity mockups.
The Publicat Group consists of several publishing houses, as can be seen in the attached graphic.



External integrations
– Catalog and sales integration with the client’s internal ERP
– Implementation of PayU and Przelewy24 payment systems
– Integration with Pocztex, Poczta Polska, and InPost logistics systems

Desktop and mobile implementation
The implementation work was divided into 10 sprints (each sprint lasting 10 business days), including: 7 business days for developers, 4 hours for QA testing, 4 hours for fixes, and 1 day for client-side testing. Each sprint included 1 day for fixes; if we needed to complete the fixes earlier, we would start another sprint. The entire implementation, including development and testing, took 5 months.
Management and progress control:
- In the Monday.com system, we maintained a board accessible to the client and the team, where we monitored project progress.
- The client reviewed each sprint and provided feedback in the sprint comments.
- Sprint closure, acceptance protocol, and work settlement were all handled remotely.
- After the implementation was complete, it took us approximately 5 days to test the BETA version, i.e., the finished content.
- We conducted testing based on the description of the business-side test scenarios provided by the client.

Preparing for eCommerce publication
Before being moved to LIVE eCommerce, it underwent a process of supplementing with content and rigorous testing.
- Manual testing in a test environment – we performed testing based on purchase scenarios prepared by Diamant’s support department.
- Load testing – our server administrator performed speed and load tests, including data exchange with SAP.
- Price and product display verification.
- After the transition to live, we re-ran the scenario testing in LIVE mode.
Post-implementation
support
We’ve been providing technical support for the system for over six years. During this time, several outages due to external factors occurred, but our team quickly identified them and implemented corrective actions. Furthermore, due to technological changes, we’ve also upgraded the Diamant platform to the next version.
During our work, we maintain high standards of work culture and continuity of knowledge, i.e.:
- Development work is conducted in a 1:1 test environment compared to the LIVE version, integrated with the SAP test environment.
- All graphic changes are first implemented on clickable mockups in Figma, known as masters, and checked for their impact on e-commerce UX.
- We have implemented a key functionality monitoring system that tests e-commerce functionality every hour.
- We maintain a code repository.
