What Let’s does
Let's Co., Ltd. is a Japanese private software company that develops and sells cost management software for the construction industry. Its flagship product, Let's Genka Kanri Go2 (レッツ原価管理Go2), is a verticalized construction cost management system that handles estimates, construction registration, ordering/receiving management, payroll processing, billing, payment assessment, deposit management, and aggregation reporting — unified across departments so that both site execution-budget management and accounting-side purchasing/sales management share equivalent functionality. The product is offered as both a perpetual on-premise license and a cloud subscription ("Let's Genka Kanri Go2 Cloud") running on Microsoft Azure, with add-on modules for customer management, material management, recurring billing, payment reconciliation, and cloud file storage (Let's Drive).
The company serves primarily small and mid-size construction firms in Japan — including general contractors, specialty contractors (waterproofing, roofing, renovation, civil engineering, landscaping) and multi-branch construction companies — through a hybrid go-to-market model combining direct sales, a nationwide network of partner shops (取扱店), certified on-site instructors (公認Instructor), and self-service evaluation via 45-day cloud free trials and online demos. Revenue is generated through a mix of one-time perpetual licenses, recurring annual cloud subscriptions, annual maintenance contracts, paid add-on modules, and customization services. Founded in 1990 and headquartered in Osaki, Miyagi Prefecture, with regional sales offices in Tokyo and Osaka, Let's has operated in the Japanese construction-software niche for over 25 years and has accumulated integrations with major Japanese accounting/payroll platforms (弥生会計, 勘定奉行, 建設奉行, PCA).

Let’s competitors and assessment
Company assessmentDirect peers
- ANDPAD: ANDPAD is a leading Japanese construction-tech SaaS platform covering project management, drawings, and field-to-office workflows. It directly competes with Let's in digitizing Japanese construction SMBs, though it is more mobile/cloud-native and broader in scope than Let's' cost-management focus.
- Photoruction: Photoruction provides construction-site management SaaS with AI-driven photo and progress tracking. It targets the same Japanese construction SMB segment as Let's, with overlapping field-data digitization use cases, though its emphasis is on site documentation rather than cost accounting.
- Infomart: Infomart operates B2B ordering and invoicing platforms with strong adoption among Japanese construction and food-service SMBs. It competes in adjacent back-office workflows (purchase orders, invoicing) that overlap with Let's' purchasing and payment reconciliation modules.
Broad incumbents
- Procore: Procore is a global construction management platform spanning project execution, financials, and field collaboration. It is a broad incumbent addressing larger contractors globally; Let's focuses narrowly on Japanese SMB cost management rather than enterprise-wide project management.
- Autodesk Construction Cloud: Autodesk Construction Cloud bundles BIM, project management, and cost tools for design-build firms worldwide. As a broad incumbent, it overlaps with Let's on cost-management capabilities for larger, design-driven projects but serves a very different buyer profile than Japanese SMB contractors.
Others
- PCA (ピー・シー・エー): PCA is a major Japanese accounting and payroll software publisher with which Let's maintains a tight integration partnership (PCA Hub launched April 2026). They are complementary rather than directly competitive, but PCA's broader accounting footprint makes it a strategic partner and adjacent option for shared SMB customers.
- Yayoi (弥生): Yayoi is Japan's dominant accounting software brand for SMBs, including construction firms. Let's integrates with 弥生会計 to feed transactional data into Yayoi's ledgers; Yayoi is an ecosystem partner rather than a direct competitor in cost-management workflows.
