Collection person

A web-based collection checklist created by organizers of drinking parties, class reunions, club fees, and after-parties.

• Simply enter the roster and amounts, paste the URL to LINE. When participants press "I've paid," it automatically gets checked off, and cash payments are recorded by tapping the name on the spot.
• Supports tiered pricing by position or grade (amounts are visible only to the individual), mixed payment methods (PayPay, bank transfers, cash), personalized reminder messages, and reception duty sharing with co-organizers.
• No registration or app required, completely free. Money is not held by the service; participants pay the organizer directly.

The distinctive feature is that it's developed based on real data. By analyzing 161 actual collection sheets created (totaling 1,954 participants and approximately 10.8 million yen), features are decided based on patterns like "frequent revisions → batch editing function" and "reception bottlenecks → co-organizer support." Some of the aggregated data is made public:
