Technology should simplify processes, but integration failures often have the opposite effect. In some cases, supermarket apps for obtaining discounts present flaws that are exhausting for users: the customer registers the products in the APP (Application), but, to obtain the discounts, when arriving at the checkout, they need to notify the attendant, show their cell phone so they can check the prices and enter them manually into the system.

This type of experience can make the process more time-consuming and less practical, going against the purpose of digitalization. Cases like these demonstrate how efficient integration between applications and internal systems is essential to improving the customer journey and avoiding frustration.

• Lack of real-time synchronization between the application and the POS (Point of Sale) system.
• Reliance on manual validation rather than direct automation in the sales system.
• Outdated IT architecture, hindering communication between digital and physical channels.
