Supporting Hakuyosha's Digital Strategy: Digitizing Laundry Slips and Launching Notification Features Across 270 Stores in 3 Months

YTAL (Headquarters: Tokyo, CEO: Yuta Okazaki) has supported the digital strategy of Hakuyosha (Headquarters: Ota-ku, Tokyo, President: Soichi Igarashi), a leader in the cleaning industry celebrating its 120th anniversary. The project involved implementing a 'PUSH notification' feature to update customers on their items and digitizing 'laundry slips' previously managed on paper. The rollout began in phases around the 120th-anniversary event on March 14, 2026, and was completed across approximately 270 stores nationwide on April 1. The cleaning industry has traditionally relied on analog methods like phone calls and postcards. While Hakuyosha introduced an official app in 2022, the digitization of slips had been delayed for three years due to the 'obligation to deliver documents' under the Cleaning Business Act. The turning point was a decision to adopt a hybrid operation that utilizes both digital and paper, following discussions with legal counsel. YTAL provided end-to-end support from requirement definition to development, building a robust system capable of handling high loads. As a result, the new customer app registration rate improved by 4.9 percentage points year-on-year, and the company expects to save hundreds of hours annually by reducing the workload associated with lost or missing slips.
