Overview

Carrier Global established a partnership agreement with Tidal Commerce with the goal of reinventing their e-commerce platforms. Through this arrangement, Carrier Global’s Director of Operations introduced an initiative to improve HVAC contractor experiences on site which required a mobile application demonstration.The goal was to deliver a mobile application experience which used Carrier Global’s new branding and leveraged their HVAC ecosystem for placing orders in real time.

Solution

We developed a system to streamline parts ordering and delivery, primarily used by technicians to manage orders efficiently. By studying the customer journey on-site and analyzing real-world interactions, we transformed manual processes into a digital workflow that reduced human error by over 50%. The system uses biometrics and OCR barcode recognition to minimize interactions, and an API structure captures Customers, Addresses, Orders, OrderItems, Products, PaymentMethods, and Shipping for end-to-end order management. Weekly demos and design reviews ensured the solution aligned with both the technicians’ workflow and the overall customer journey, while remaining flexible for future feature expansion.
