Intelligent, efficient, and comprehensive financial solutions
Users can conveniently add all types of documents (invoices, receipts, bank statements, etc.) through multiple methods including local file upload and photo capture. Supports multiple formats — PDF, images, Excel — plus bulk processing. Enables centralized electronic archiving and management of all receipts.
Solves the problem of scattered, hard-to-find documents, and dramatically improves the efficiency of receipt collection and management.
Using advanced AI technology, the system automatically recognizes and extracts critical information from documents (especially Japanese-format invoices and bank statements): corporate registration number, transaction date, transaction details, amount, tax rate, tax amount, recipient name, and registration number.
Dramatically reduces manual data entry workload, improves data accuracy, and serves as the core engine driving financial automation.
Based on document information recognized by AI and pre-configured or learned accounting rules, the system automatically generates accounting voucher drafts. It intelligently matches account codes, recommends tax classifications, and handles Japan-specific consumption tax rules (e.g., tax-exempt transaction flags, multi-rate journal entries). Users can review and edit online.
Dramatically improves the efficiency and consistency of voucher creation, lowers the professional barrier to entry, and guarantees compliance with Japanese accounting standards.
Provides a clear multi-user role management system (accountant and client staff). Accountants can easily create and manage all their client accounts, invite client staff to collaboratively upload documents, and view and manage receipts and vouchers on a per-client basis.
Purpose-built for bookkeeping agencies — optimizes multi-client collaboration workflows and elevates both service efficiency and the client communication experience.
The system ships with a built-in chart of accounts compliant with Japanese standards, while also allowing users to upload custom charts of accounts. It supports adding and managing client bank account information, with automatic linking of bank accounts as sub-accounts — laying the foundation for subsequent accounting processing and bank statement matching.
Provides the flexibility needed for essential accounting setup, adapts to the specific needs of different clients, and ensures accuracy in all downstream automated processing.
Records the complete lifecycle of each document in detail — from upload, recognition, and voucher generation to edits and final status. Maintains logs of all significant operations (such as voucher revisions and document deletions) including the operator, timestamp, and content, making audit trails and issue troubleshooting straightforward.
Ensures transparency and compliance throughout the financial processing workflow, providing a reliable and trustworthy audit trail.
