What INVOICE does

INVOICE Inc. (株式会社インボイス) is a Japan-based business process outsourcing (BPO) company founded in December 1992 and headquartered in Kojimachi, Tokyo, with a planned relocation to Toyosu in October 2026. The company operates as a wholly-owned subsidiary of Fuyo General Lease Corporation (芙蓉総合リース株式会社) within the Fuyo Lease Group. INVOICE provides outsourced back-office services across three primary segments: accounting (consolidated billing for telecommunications via Gi通信 and public utilities via OneVoice公共, document issuance via OneVoice明細, and accounting automation via the OneVoicePalette no-code platform), general administration and IT systems (Invoice Hikari fiber broadband, @George enterprise WiFi, and ICT infrastructure services for offices, dormitories, and schools), and sustainability (OneVoice Energy Data for digitizing energy usage from paper invoices to support CO2 Scope 1/2 emissions calculation). The company serves approximately 16,000 enterprise and government customers across Japan, with a disclosed 99.1% service continuation rate and annual processing of 6 million documents across 4,000+ recognized service provider invoice formats.

The company's technology stack centers on RPA and AI-OCR for automated invoice data extraction and processing, supplemented by a March 2026 service integration with LayerX Corporation's AI-powered Bakuraku Invoice Receipt platform for end-to-end accounting automation. INVOICE holds Privacy Mark (JIS Q15001) and ISMS/ISO 27001 certifications supporting its handling of sensitive customer financial data. Revenue is generated primarily through recurring monthly subscription fees tied to service volume and scope, with public pricing disclosed only for OneVoice明細 (initial setup ¥100,000, monthly ¥25,000) and OneVoicePalette (tiered from free to ¥20,000/month). Go-to-market combines direct field sales, inside sales, and partner channels across regional sales offices in Sendai, Nagoya, Osaka, and Fukuoka, supplemented by group company referrals within the Fuyo Lease Group and technology partner channels including LayerX and Higo Bank. Marketing leverages the Seikyu ABC owned-media platform, free webinars, email newsletters, and PR press releases targeting Japanese accounting and finance professionals.

Core offering

INVOICE provides business process outsourcing (BPO) services focused on consolidated billing and back-office operations for Japanese enterprises. Its core services aggregate and process thousands of telecommunications (Gi通信) and public utility (OneVoice公共) invoices into a single monthly bill on behalf of multi-location corporate customers, supplemented by cloud-based document issuance (OneVoice明細), a no-code accounting automation platform (OneVoicePalette), and energy usage data digitization for CO2 emissions reporting (OneVoiceエネルギーデータ). The company also offers ICT infrastructure services including business fiber internet (Invoice Hikari) and enterprise Wi-Fi (@George).

Product overview

INVOICE provides a portfolio of three BPO service lines for accounting, general affairs/IT systems, and sustainability departments. The core accounting BPO services are built around consolidated billing — specifically Gi Communication (telecommunication charges) and OneVoice Public Utilities (electricity, gas, water charges) — which consolidate multiple invoices into single monthly bills and automate receipt, journalizing, payment, and storage processes. These core services are complemented by OneVoicePalette (an accounting processing efficiency platform that auto-generates accounting entries and department allocation reports from consolidated billing data) and OneVoice Meisai (a cloud-based electronic document issuance system). A dedicated sustainability offering, OneVoice Energy Data, digitizes energy usage from invoices to support CO2 Scope 1/2 emissions calculation. Additional services include Invoice Hikari (business fiber internet), @George (enterprise Wi-Fi), and ICT infrastructure services through affiliated companies.

Expansion highlights5 records

Broad incumbents

• Yayoi (Kabuwalk-style Yayoi Holdings): Long-established Japanese accounting software vendor (弥生) serving SMEs with desktop and cloud accounting, payroll, and invoice products. Broader incumbent in the same Japanese back-office digitization category as INVOICE, with wider product portfolio but lighter BPO service emphasis.
• TKC Corporation: Japanese accounting, payroll, and tax compliance software provider closely tied to the tax accountant channel. Comparable to INVOICE in serving Japanese enterprise back-office and compliance needs, with a different go-to-market via CPA firms.
• OBC (Ohsaki Business Computer): Major Japanese accounting and payroll software vendor (勘定奉行 series). Established incumbent in the enterprise back-office software category overlapping with INVOICE's accounting BPO target market.

Direct peers

• Money Forward: Public Japanese cloud accounting and back-office SaaS company serving SMEs and enterprises. Comparable to INVOICE in targeting accounting/finance department digitization, though Money Forward is software-first rather than BPO-delivered.
• freee: Leading Japanese cloud accounting and HR/payroll SaaS provider for SMEs. Competes with INVOICE for the same enterprise back-office budget on invoice and accounting automation, differing mainly in delivery model (SaaS vs. BPO).
• Works Applications: Japanese enterprise cloud ERP/HCM vendor with HUE series covering accounting and back-office workflows. Competes with INVOICE for large-enterprise accounting/finance digital transformation budgets in Japan.
• MK System: Japanese developer of invoice and accounts-payable automation software (e.g., MK Invoice). Closely comparable to INVOICE in automating Japanese invoice receipt and compliance with the qualified invoice system, differing in delivery model (pure SaaS vs. BPO).
• LayerX: AI-native Japanese fintech building Bakuraku Invoice Receipt and related automation SaaS for back-office workflows. Direct competitor and strategic partner of INVOICE — both target the same enterprise invoice-processing pain point, with LayerX leaning SaaS/AI and INVOICE leaning BPO service delivery.

Others

• Extrack (Extrack Co., Ltd.): INVOICE's partner for ICT infrastructure design, construction, and maintenance services. Adjacent/ecosystem peer rather than direct competitor — provides the server/network/security services INVOICE bundles into its BPO offering.

Regional players

• RPA Holdings (now BLUE TRUST): Japanese RPA and AI-OCR vendor specializing in back-office automation including invoice processing. Comparable to INVOICE in the Japanese back-office automation space with overlap in AI-OCR/RPA tooling, though RPA Holdings is more software-centric.
