invox Expense Management, developed and operated by invox Inc. (Head Office: Shinjuku-ku, Tokyo, Representative Director: Akira Yokoi), has improved the accuracy of receipt data digitization through enhancements to its AI-driven data processing.
This improvement, based on advancements in AI technology, enables more accurate data conversion even for receipts with varying formats and non-standard descriptions. This reduces the burden of confirmation and correction work, promoting greater efficiency in expense management operations.
Challenges in Receipt Digitization and Background of Improvements
Amidst the digitalization of businesses and compliance with the Electronic Bookkeeping Act, the electronic processing of expense reports is rapidly advancing.
Since its service launch in July 2024, invox Expense Management has continuously updated its functions to align with practical needs, such as exceptional cost-performance and support for application and approval via smartphones.
These efforts have been well-received, and the number of users is steadily expanding.
However, receipts often have diverse formats and non-standard descriptions, making accurate reading difficult for conventional AI OCR in some cases. Some users reported issues such as 'trouble confirming and correcting reading results' and 'the inability to achieve complete automation, leaving manual work remaining.'
To solve these issues, invox Expense Management has fundamentally revised its AI-driven data processing and implemented improvements to enhance the accuracy of receipt data digitization.
This increases the recognition accuracy of key items such as amounts and dates, reducing the correction work burden that previously occurred.
This improvement will be automatically applied to all plans, with no increase in monthly basic fees or usage fees per active user.
The invox series will continue to work on functional improvements, including enhancing data digitization accuracy.
