Our company endorses April Dream, which aims to make April 1st a day for announcing dreams. This press release represents the dream of 'SUZUKI SOFT LABORATORY' and 'VTeacher.'
As part of our 'VTeacher AI' initiative, our company has released 'fukugyo,' an OSS for Claude Code, which is an AI agent that supports side job workers and freelancers (primarily IT engineers) with debt collection issues.
We aim to create a society where side job workers, freelancers, sole proprietors, and small business owners can manage invoicing, payment confirmation, and, in the event of non-payment, handle disputes without being overly burdened. **They shouldn't have to abandon the work or challenges they truly wish to pursue due to anxieties about invoicing or non-payment.** Our dream is to gradually make this a normal state of affairs.
fukugyo
■Background of Development
The representative himself faced non-payment issues as a sole proprietor and keenly felt the immense burden of single-handedly managing demands, organizing evidence, drafting certified content mail, and preparing for court submission. In the world of side jobs and freelancing, monthly administrative tasks such as confirming contract terms, recording daily work hours, creating invoices at the end of the month, and confirming payments often become a significant burden. Furthermore, if payment delays or non-payment occur, individuals face a substantial psychological and practical load in drafting demand letters and preparing for subsequent actions. Our company believes that by utilizing AI for these challenges, we can streamline daily invoicing-related tasks and establish a system that makes it easier to take the next step in the event of non-payment. Therefore, we have developed and released 'fukugyo,' an OSS specifically designed for side job and freelance operations, running on Claude Code.
■Main Features of 'fukugyo'
1. Supports Contract Confirmation
Assists in confirming remuneration, payment terms, and clauses to be aware of, based on contract files. This helps prevent oversights before a project begins.
2. Streamlines Daily Work Management
Supports daily work record-keeping and monthly aggregation, making it easier to organize necessary information for end-of-month invoicing.
3. Supports Invoice Issuance
Assists with invoice issuance based on monthly work information and contract terms. This reduces routine invoicing tasks and helps prevent creation errors.
4. Supports Initial Response to Non-Payment
If a payment due date passes, it assists in drafting demand email messages. This facilitates smooth follow-up after invoicing.
5. Supports Certified Content Mail Creation
In case non-payment continues, it assists in drafting certified content mail. This helps organize and clarify records before proceeding to the next step.
6. Supports Preparation for Court Payment Orders
If necessary, it assists in preparing documents for a court payment order. This looks beyond just daily operational efficiency to establishing an initial response system for troubles.
7. Released as OSS
It is released in a way that Claude Code users can easily introduce and improve upon, allowing for practical application and development tailored to real-world operations.
■Significance of the Release
Currently, institutional reviews are being discussed regarding contract-related services and legal practice support using AI, and the AI legal tech market is likely to expand further in the future. Anticipating these environmental changes, our company has first materialized concrete examples of AI utilization in the familiar and pressing area of invoicing and non-payment response for side job workers and freelancers. The release of 'fukugyo' is not merely a technical disclosure; it is an initiative, based on the developer's own experiences, to demonstrate how AI can help reduce burdens and provide initial support during troubles in practical work settings.
■Future Outlook
Moving forward, our company will continue to develop practical support tools utilizing AI, striving to create an environment where side job workers, freelancers, sole proprietors, and small business owners can work with greater peace of mind. We also plan to strengthen cooperation with accounting, contract, and invoicing-related tools, and further expand functions tailored to practical operations.
