Project Brief

Modernization of POS solution to improve operational efficiency and deliver superior customer experience


  • PT Trans Retail (Carrefour) Indonesia wanted to replace its POS system and implement a web-based POS solution to centralize management and upgrade.

  • The web-based POS system should work with the client’s existing hardware and a new set of hardware and peripherals.
  • It should seamlessly integrate the entire supply chain by consolidating over a hundred existing applications and submodules.
  • The solution had to accommodate POS core functionalities, include new features and enhancements and incorporate future technology.

  • PT Trans Retail (Carrefour) Indonesia wanted to automate its operations and centralize data management for quick turn around of reports.
  • The system should support the client’s marketing programs to improve the customer experience.

  • The POS solution should work offsite for out of store operations and offline for an uninterrupted store operation.


  • PT Trans Retail (Carrefour) Indonesia partnered with Exist to implement the POS solution. Exist provided the technical expertise and experience in managing complex retail IT projects.

  • Exist team built and delivered a thin-client, web-based POS solution within the given timeframe. The re-designed system centralized data to provide more timely information. In addition, remote data backup services were implemented for data protection.
  • The POS solution was able to seamlessly integrate the client’s entire supply chain by consolidating over a hundred existing applications and sub-modules — saving our client considerable expense both on hardware and software costs.
  • The thin client installed on the POS terminals was initially intended to facilitate communication/instructions from the POS system to the devices since by default the browser is not allowed to manipulate the devices. Later on, it was extended to support offline functionalities.

  • The POS solution has been successfully deployed via a staggered rollout with initial pilot outlets followed by rollout groups, providing a full performance of POS solution and bringing interactivity for both cashier clerks and customers with dual touchscreens.

  • Managing a team over an eight-month period for the first iteration, Exist provided key project management, business analysis, development, and QA testing competencies.


  • Successfully aligning with the client’s business initiatives, Exist has helped the client meet its ongoing POS upgrade in support of a centralized system.

  • PT Trans Retail (Carrefour) Indonesia is starting to realize the benefits emerging from use of the new system such as improved operational efficiency, enhanced data collection, and reporting,
    and increased customer relationship management.
  • The POS solution was able to seamlessly integrate the client’s entire supply chain by consolidating over a hundred existing applications and sub-modules — saving our client considerable expense both on hardware and software costs.
  • Managed Cost and Shortened Time to Market
    The POS solution has provided substantial cost and time savings to the client. The web-based system makes prototyping, implementation and upgrade fast and easy. The overall cost is less compared to upgrading their existing POS system. In addition, the web-based POS system does not require extensive hardware or software installations or additional equipment.

  • Operational efficiency
    PT Trans Retail (Carrefour) Indonesia has seen significant improvements in its control over operations. Head office has up-to-date access to critical sales information and details of key performance indicators across multiple sites.

  • Further, with the POS’ seamless integration with the client’s merchandising system, vendor management system and other apps, the POS solution enabled improved visibility and management of inventory.
  • Improved customer relationship
    With its dual display support, the POS solution enables instant interaction with the customers. Customers can provide real-time feedback just by a touch on the screen. This type of customer-facing display also offers options for building brand awareness and running marketing promotions.

    Today’s consumers are more informed, socially-connected, and mobile. The client is poised to unlock more opportunities with the POS solution and some of these opportunities include retail analytics and improved loyalty programs.
