What PCA does

PCA Corporation (ピー・シー・エー株式会社), founded August 1, 1980 and headquartered in Tokyo's Chiyoda-ku, is a publicly listed Japanese enterprise software company (TSE: 9629) that develops and sells integrated back-office software for small and medium enterprises (SMEs) and mid-market companies across Japan. The company operates a three-tier product portfolio: PCA Arch, an AI-integrated cloud suite launched in October 2023 from ¥9,000/month that bundles financial accounting, payroll, HR, and sales management modules with an embedded AI Assistant and shared cloud storage; PCA Cloud, the long-running cloud service (operational since 2008) starting at ¥12,600/month that serves over 25,000 corporate customers; and PCA Subscription, an on-premises subscription variant from ¥4,500/month for organizations preferring local server deployment. PCA discontinued perpetual package license sales in March 2024 (with support ending March 2029), driving the installed base toward recurring subscription contracts.

The portfolio is supplemented by the PCA Hub add-on modules — expense management, electronic document storage (eDOC, JIIMA-certified), payroll slip delivery, year-end tax adjustment, labor management, and transaction detail services — plus specialized vertical accounting products for medical, public interest, and social welfare corporations, and construction industry accounting. Integrations include MoneyLook (aggregating data from 1,300+ Japanese financial institutions), Cronos Performance attendance, Yamato Transport B2Cloud, kintone CRM, Microsoft Office, and Peppol e-invoicing. Revenue is generated through monthly cloud subscriptions, on-premises subscriptions, annual PSS support contracts, and paid implementation/training services priced ¥40,000–¥350,000 per engagement. Distribution combines a 572-firm certified sales partner network with direct enterprise sales, self-service online trials (2-month free), and a Professional Practitioner Consortium of accountants and tax advisors. The company is independently operated with no parent, holds SOC2 Type II, ISO 27001/27017/27018, CSA STAR Level 2, and HITRUST CSF certifications, and employs 501–1,000 people. CEO Fumio Tamai leads the organization.

• SmartHR, Inc. Leading Japanese cloud HR and employee management platform serving SMEs and mid-market companies. Directly competes with PCA's payroll and HR management series (PCA 給与, PCA 人事管理) and is rapidly expanding into adjacent back-office workflows.
• freee K.K. Cloud-native Japanese accounting and HR SaaS for SMEs and freelancers. Competes head-to-head with PCA Cloud and PCA Arch in cloud accounting, payroll, and HR; backed by significant venture investment and pursuing aggressive SMB pricing.
• Yayoi Co., Ltd. (弥生株式会社): Japan's leading SME accounting software provider, offering Yayoi Accounting and Areaman series for small businesses. Directly competes with PCA in Japanese back-office software for SMEs, with overlapping customer segments in construction, retail, and service industries.
• Cybozu, Inc. (サイボウズ): Maker of kintone, the leading Japanese low-code business platform with broad SME penetration. PCA Shokon Cloud integrates with kintone, but kintone also competes as an alternative platform for SMEs building custom back-office workflows without dedicated accounting software.

Broad incumbents
