Terasaki Releases Version 5.5 of mitoco Accounting System on August 24, 2026

Terasaki Unveils Updated mitoco Accounting System

Terasaki Co., Ltd., headquartered in Chuo-ku, Tokyo, has announced the upcoming release of version 5.5 of its cloud accounting software, mitoco Accounting, scheduled for August 24, 2026. This upgrade is particularly timely, falling just before the implementation of the revised invoicing system that comes into effect on October 1, 2026.

With this version, Terasaki aims to reduce the operational burdens associated with master registration and voucher entry in response to the new tax law concerning exemption procedures for transactions with tax-exempt businesses. Key features include a consumption tax rate switching function and a setting verification tool, ensuring smoother adaptation to the impending regulatory changes.

Key Enhancements in Version 5.5

The major updates in this version pertain to crucial aspects of financial and management accounting (GL), payment management (AP), and accounts receivable management (AR). Below are the highlights of the enhancements:

Adjustments for the Invoice System Revision

Effective October 1, 2026, the revised invoicing system will introduce changes to input tax deduction procedures, particularly impacting how taxpayers process transactions with tax-exempt vendors. The following enhancements are designed to ensure compliance and improve usability:

1. Consumption Tax Rate Master Update
The system will now hold information regarding consumption tax rate switching within the tax rate master. This allows users to pre-register effective dates and applicable tax codes, providing a streamlined view of valid rates based on a designated reference date.

2. Refined Reference Method for Account Title Master
Adjustments have been made to the reference method for consumption tax classification codes to ensure correct application following the revised invoicing transitions. This will enable seamless switching of tax rates pre- and post-revision during voucher entry.

3. Master Configuration Verification Tool
A new check tool has been added to facilitate bulk verification of entries in the Consumption Tax Rate Master and Account Title Master. This tool enables users to efficiently confirm the accuracy of settings associated with the tax reform, culminating in a comprehensive report of results.

Improvements in Accounts Receivable Management (AR)

- Sticky Note Feature for Reconciliation Processing

The new sticky note function allows users to record investigations during reconciliation procedures. These notes remain accessible in the workspace for future reference, enhancing continuity in data processing.

- Re-execution of Canceled Reconciliation Procedures

The system now retains history even when reconciliations are canceled, allowing users to re-execute from saved historical data easily. Information regarding the details, amounts, and any notes from previous executions can be quickly retrieved and reused.

- Inclusion of Previously Excluded Cash Receipts

Cash receipts that were previously considered out of scope can now be included in cash receipt transfer processing, expanding the operational capability of the system.

- Enhanced Voucher Creation Methods

The method for creating cash transfer vouchers within receivables reconciliation has been redesigned for improved efficiency. Users can now choose to bypass voucher creation under certain conditions, potentially decreasing processing time by approximately 30%.
