What Kyushu Software does

Kyushu Software Co., Ltd. (九州ソフトウェア株式会社) is a privately held Japanese system integrator founded in 1989 and headquartered in Saga City, Saga Prefecture, within the Kyushu region. The company designs, develops, and maintains custom business software for small and medium-sized enterprises in the retail, manufacturing, and service industries, acting in effect as an outsourced systems department for clients that lack internal IT personnel. Its portfolio comprises three interconnected offerings: (1) entrusted/custom development (受託開発), which covers the full lifecycle from requirements analysis and system design through development, hosting at the company's server center, and post-delivery maintenance; (2) the Zero Development Cost Plan (開発費ゼロプラン), a subscription-style engagement from ¥20,000 per month that eliminates upfront development fees and bundles feature additions and changes during the contract term, currently limited to Saga Prefecture clients; and (3) the EDI / Order-Receipt Data Conversion System (受発注データ変換システム), a managed service that digitizes paper-based B2B order and invoice documents for network exchange and includes 24/7 monitoring, helpdesk, and security management. The underlying technology stack is conventional custom application development supported by hosted server infrastructure; there are no disclosed AI/ML, API, or platform-product components.

The business operates as a regional, consultation-led B2B services provider with all delivery handled by an in-house engineering team; no third-party resellers, channel partners, or institutional investors are involved. GTM is sales-led and enterprise-field-sales in character: prospective clients reach the company through its corporate website, telephone, or inquiry form, after which the company conducts a needs consultation and proposes a tailored engagement. Pricing is predominantly quote-based for custom projects, with the Zero Development Cost Plan providing a transparent, low-ticket recurring entry point aimed at small businesses. Leadership is concentrated in Representative Director Takanori Nakamura (中村孝徳), and the firm is closely held with a registered capital of ¥1,000,000. Headcount is reported in the 1-10 range, and the most recent publicly documented corporate events are the March 2018 website relaunch and the July 2018 commemoration of the company's 30th anniversary; no post-2018 funding rounds, acquisitions, or geographic expansions are present in the source data.

Revenue model

1. Custom Development Services (受託開発): Bespoke software development services where systems are built from scratch to meet specific client operational needs. Revenue is generated through project-based contracts for custom system development, potentially with ongoing maintenance fees.
2. Zero Development Cost Plan (開発費ゼロプラン): A unique recurring revenue model where no upfront development cost is charged; instead, a monthly service fee is collected. This allows clients to start systems without initial capital outlay while providing Kyushu Software with predictable recurring income. Limited to Saga Prefecture customers.
3. EDI Data Conversion Services (受発注データ変換システム): Services related to converting traditional paper-based order and invoice documents into electronic data formats for exchange over internet and telephone networks. Revenue generated through system setup, implementation support, and ongoing operational/maintenance services.

Core offering

Kyushu Software provides commissioned (bespoke) software development, a monthly-fee system maintenance plan with no upfront development cost (Zero Development Cost Plan), and an EDI (Electronic Data Interchange) data conversion service that digitizes paper-based order and invoice documents for B2B commerce. Customers are retail, manufacturing, and service businesses in the Saga / Kyushu region of Japan, typically those lacking dedicated internal IT staff.

Product overview

Kyushu Software offers a portfolio of three interconnected software development and data services: (1) Custom/Entrusted Development — the core offering of bespoke systems built from requirements analysis through to deployment and ongoing support, including hosted server infrastructure; (2) the Zero Development Cost Plan — a monthly-fee engagement model for existing systems requiring long-term maintenance and evolution, charging no upfront development fees; and (3) the EDI (Electronic Data Interchange) System — a specialized service that digitizes paper-based order and receipt documents into standardized electronic formats for network transmission, enabling supply-chain efficiency. The company primarily serves retail, manufacturing, and service industries in the Saga region of Kyushu, Japan.

Products and services

• Custom/Entrusted Development (受託開発) Bespoke software development built from the ground up to streamline and improve client business operations. Kyushu Software acts as the client's in-house systems engineering department, providing requirements analysis, system design, development, and post-delivery support and maintenance, including server center hosting. Targeted at retail, manufacturing, and service-industry customers whose needs cannot be met by off-the-shelf package software.
• Zero Development Cost Plan (開発費ゼロプラン) Monthly-fee service model in which no upfront development cost is charged, eliminating additional fees for unexpected additions or changes during the contract period. Priced from ¥20,000 per month; available to clients within Saga Prefecture (out-of-prefecture clients by consultation). Designed for small-scale starts or clients without a dedicated IT staff member, covering long-term system maintenance and feature evolution.
• EDI Order-Receipt Data Conversion System (受発注データ変換システム) Electronic Data Interchange (EDI) system that converts traditionally paper-based order documents, delivery slips, and other trade documents into standardized digital formats for exchange over the internet and telephone networks. Service menu includes account management, implementation/setup support and configuration for new counterparties (specification coordination, environment construction, testing and production cutover), and 24/7/365 system operations (monitoring, helpdesk, ad-hoc transmission handling, incident response, and security management).
