TeraDox Co., Ltd. (HQ: Shibuya-ku, Tokyo; CEO: Keiji Saito) has launched the 'Spot Transmission Function' for its electronic contract service 'Keiyaku Daijin,' allowing users to send additional contracts even after exhausting their monthly transmission quota.
### Background of the Spot Transmission Function Release
'Keiyaku Daijin' is a one-stop electronic contract service for creating, sending, concluding, and managing contracts. Since its release in May 2021, it has been used by many corporations and sole proprietors.
Many users had expressed concerns about reaching their transmission limits during busy periods or toward the end of the month, which previously required an upgrade to a higher-tier plan. However, upgrading a plan can be a financial hurdle for those who only need to send a few extra documents temporarily. To address this issue, the 'Spot Transmission Function' was developed to allow users to purchase only what they need when they need it.
### What is the Spot Transmission Function?
This feature allows users on paid plans to purchase 'tickets' to send additional electronic contracts after their monthly quota is used up.
- Tickets are available for 550 yen (tax included) each.
- There is no expiration date; purchased tickets can be used anytime.
- The system first consumes the monthly quota, and spot tickets are only used once the quota is exhausted. The sending process remains identical to regular transmissions.
- This function is available exclusively to users on paid plans.
### Plan Guidance
Spot transmission is an option for temporary overages. For those consistently sending high volumes, upgrading to a higher plan remains more cost-effective.
- For Starter Plan users (20/month): Upgrading to Basic (6,600 yen/month) is better if sending 25+ contracts monthly.
- For Basic Plan users (50/month): Upgrading to Premium (9,900 yen/month) is better if sending 57+ contracts monthly.
- Premium Plan (100/month): Users exceeding 100 contracts can utilize spot tickets or contact support for larger volumes.
Annual payment options are also available, offering one month free compared to monthly billing.
- Starter Plan: 4,400 yen/month → 2,020 yen/month (monthly avg with annual pay)
- Basic Plan: 6,600 yen/month → 6,050 yen/month (monthly avg with annual pay)
- Premium Plan: 9,900 yen/month → 9,075 yen/month (monthly avg with annual pay)
