Living Service Provider Nac Adopts Platio and Creates ‘Delivery Management App’ to Eliminate Paper Delivery Notes

Press Release

Tokyo — April 27, 2023 — Asteria Corporation (Japan listed, Security Code: 3853) announced today that Tokyo-based Nac Co., Ltd., which offers a variety of living services, has introduced Asteria’s no-code*1 mobile app building tool Platio and promoted digital transformation of its on-site delivery operations. Nac also plans to expand the usage of a Platio app intended to address the “2024 issue*2” facing the logistics industry.

Background and Impact

Founded in 1971, Nac provides living services such as manufacturing and sales of rental water dispensers under the brand name “CreCla” and the rental business, as well as the housing business. The company, which is listed on the Prime Market of the Tokyo Stock Exchange, actively adapts to change and positions “immediate action” as one of the employee action guidelines. In order to improve operational efficiency and swiftly respond to market changes, Nac has been promoting in-house development of core systems and introduction of IT tools.

While stepping up company-wide efforts to improve operational efficiency, Nac focuses on streamlining its delivery operations for CreCla, one of its mainstay businesses. Every day, each employee had to sort 60 or so duplicate delivery notes in chronological order by delivery date and input data into the core system after returning to the office, which led to an increase in man-hours and data entry errors, among other problems.

Therefore, the company began considering in-house production and utilization of mobile apps that could quickly accommodates the requests of on-site workers. The decision was made to introduce Platio, which can be used offline even in areas where there is no signal, such as basement and higher floors, and can integrate data with the core system. Nac employees then created their unique “Delivery Management App” with Platio.

The “Delivery Management App” works with the core sales management system via Asteria’s data integration middleware ASTERIA Warp, thereby automatically linking delivery data in the system to the app. This allows about 400 delivery staff members to immediately check the delivery destination with a smartphone, instead of using delivery notes. The app can also connect to a mobile printer, allowing delivery staff on the go to print the necessary delivery notes. The staff members can register delivery records into the app so that they are no longer required to input such data into the system. As a result, the time required for each delivery has been reduced from about 40 minutes to about 5 minutes, saving about 56,000 hours of work per year.

In the future, Nac plans to expand the use of this app, which is currently only introduced at directly-managed stores, to its member stores as a new initiative to address the 2024 logistics issue by significantly reducing the workload and overtime hours of delivery staff members. The aim is to further enhance the service quality and operational efficiency of the overall CreCla business network.

Comment from Nac

As part of our efforts to build systems in-house, we have been working on an agile development of our core sales management system, and along with this project, we created the Delivery Management App using Platio. Usually, it is not easy to modify an app in accordance with the changes that had been made to the core system. But with Platio, we were able to deploy an app while updating it promptly and flexibly without coding.

Going forward, we’d like to manage the maintenance schedule for water dispensers with an app and further increase the efficiency of product management. At the same time, we are seeking to offer member stores the Delivery Management App to help improve the service quality of the overall CreCla network.
