MerryBiz

MerryBiz Inc. operates as a Business Process as a Service (BPaaS) provider, specializing in online accounting and back-office outsourcing for the Japanese market. The company was established on July 4, 2011, by Hiroki Kudo, a seasoned entrepreneur with prior experience at IBM, GREE, and as a founding member of the e-commerce platform Locondo. Kudo was motivated by the observation that complex paperwork and administrative procedures in Japan consumed an inordinate amount of time for entrepreneurs, diverting focus from their core business activities.

The company's core offering, "Virtual Keiri Assistant" (Virtual Accounting Assistant), provides a dedicated online team of professional accounting staff to handle a wide spectrum of clerical tasks. Services include expense report processing, journal entry, accounts payable/receivable management, monthly closing, and the issuance of invoices. MerryBiz serves a diverse client base, ranging from startups and small-to-medium-sized enterprises to publicly listed corporations like Gunosy and SmartNews. The business model is subscription-based, with revenue generated from service plans tailored to client needs. A key feature of the service involves clients mailing physical documents like receipts and invoices, which MerryBiz then digitizes and processes using its proprietary systems and a network of remote accounting professionals.

In addition to its outsourcing services, MerryBiz provides "MerryBiz Keiri DX," a hands-on digital transformation consulting service. This offering assists companies with migrating to cloud accounting systems and redesigning their business processes, leveraging a professional team of consultants, IT specialists, and experienced finance executives. The company has secured multiple rounds of funding, including a seed round in 2014, and later-stage investments from partners like Fuyo General Lease. A recent capital and business alliance with The Shoko Chukin Bank in August 2025, involving a ¥200 million investment, aims to strengthen its support system for small and medium-sized enterprises nationwide. In February 2022, Yutaro Yamamuro was appointed Representative Director and President, succeeding founder Hiroki Kudo.
