■ Background of Development
"Accounting is an afterthought" — the essence of this challenge faced by many business owners is not merely the effort involved, but the trade-off between the accuracy and man-hours of accounting processing. To create accurate ledgers requires specialized knowledge, and entrusting it to specialists incurs costs and communication losses. KOZOTAI was developed to solve this structural problem.
■ Why KOZOTAI is Chosen: "Clean Ledgers" Completed with Less Effort
The core of KOZOTAI lies in its ability to automatically generate consistent journal entries after the AI understands accounting standards and company-specific rules.
In general accounting software, staff members have to select account titles, set sub-accounts, and unify input rules each time. With KOZOTAI, the AI refers to the "Guidelines for Accounting for Small and Medium-sized Enterprises" and the company's own chart of accounts in advance, ensuring that ledgers are consistent regardless of who inputs the data or when it is input.
Staff simply input events. The AI creates journal entry proposals, and humans provide final approval, a simple flow that simultaneously enhances the quality and speed of accounting.
■ Main Features
Automatic journal entries from natural language and documents: AI generates journal entries simply by inputting colloquial phrases like "train fare 500 yen" or "taxi fare 1,500 yen," or by directly inputting invoices and bank statements.
Compliance with accounting standards and company rules: Achieves consistent processing by referring to the "Guidelines for Accounting for Small and Medium-sized Enterprises" and the company's own chart of accounts.
AI and human double-check: AI creates journal entry proposals, and staff provide final approval. Change logs are fully recorded.
Functions as accounting software: Capable of creating and managing general journals and general ledgers, as well as financial statements required by the Companies Act.
API integration: Direct requests to AI agents from Slack and external systems are possible.
■ Pre-registration Campaign
