What It Is

Arch（アーチ） is provided by Arch Inc. in Japan and is positioned as a digital platform connecting construction sites with construction equipment rental companies. Its core goal is to replace traditional paper, fax, and phone-based workflows by moving quotation requests, ordering, site management, inspections, and safety KY processes for rented construction equipment online. The website lists major Japanese construction companies such as 戸田建設, 東亜建設工業, 鹿島建設, and 西松建設 among its customers.

Core Features and Collaboration

The main focus of Arch Rental Platform is rental item management. It supports online quotation requests to multiple rental companies, quote comparison, in-system price negotiation, and ordering at any time based on saved quotations, while keeping an order history. The ordering workflow includes supervisor approval, making it suitable for construction sites that require approval controls. On the site side, users can centrally manage items from different rental companies, including on-site inventory, lending to subcontractors, returns, stocktaking, and more efficient inspections through digital checklists. There is also a machinery reservation feature, allowing equipment to be booked via mobile, PC, or tablet, with settings by morning/afternoon/night or by time slot, and operating reports can be exported. Digital KY covers KY form creation, main contractor approval, worker signatures, and sharing to LINE groups.

Pricing, Security, and Support

The website does not publish specific plans, unit prices, free versions, or trial rules. It only provides “料金” and “デモ” options in the inquiry form, so buyers need to contact sales before purchase to confirm the billing model. In terms of security, Arch states that it has obtained JIS Q 27001:2023 / ISO/IEC 27001:2022 ISMS certification, and its privacy policy also describes measures such as access restrictions, access logs, and prevention of unauthorized access. For implementation, the company emphasizes support from its Customer Success team, including initial setup, account configuration, on-site operation guidance, and adoption support. It also discloses a 99% service continuation rate.

Pros, Cons, and Best Fit

Its strengths are its highly vertical focus and its closed-loop coverage of rented equipment workflows, from quotation requests to returns, inspections, reservations, and safety KY, while also supporting mobile use on-site and approval audit trails. Its drawbacks are limited pricing transparency and the lack of disclosed information about APIs, open integrations, and deployment options. Apart from LINE sharing, there are no visible details about integrations with ERP, accounting, procurement, or rental company back-end systems. It is better suited to Japanese general contractors, civil engineering/construction project sites, and teams that manage large volumes of rented construction equipment while still relying on paper and phone-based workflows.

Access from China and Alternatives

Access from China cannot be determined from the available text, and payment methods are not disclosed. Since the product is clearly aimed at the Japanese construction industry, Chinese companies would also need to assess language, time zone, contracts, payments, data compliance, and compatibility with local construction management workflows. Domestic alternatives to consider include construction digitalization products from Glodon, Pinming Technology, Luban Software, and Ming Yuan Cloud. If the need is only for general approvals, forms, and on-site collaboration, lightweight workflows can also be built with DingTalk, WeCom, or Feishu.
