Each member pays the agreed amount daily, weekly, or monthly.
What is a tontine?
A tontine is a rotating savings group. Members contribute a fixed amount on a regular schedule, and one member receives the pooled amount each cycle. The same idea is also referred to as a ROSCA, susu, stokvel, chit fund, or savings circle in different communities.
How tontines work
The full pot goes to one member each round based on the group’s chosen order.
The system depends on shared records and a clear view of contributions.
Why recordkeeping matters
Many groups still rely on paper notebooks, chat threads, or memory. Those methods can work day to day, but they make disputes harder to resolve and can be difficult to use as a clear payment history.
- Paper can be lost or damaged.
- Payment history is hard to verify later.
- Members and merchants often need a clearer record of commitments.
What Tonty does
Tonty is first a voice-first shop notebook for sales, expenses, customer credit, and repayments. Tontines are a secondary use case for documenting contributions and turns. Tonty does not hold, transfer, or manage user funds.
Track who paid, when they paid, and what round the group is in.
Small merchants can keep a Cahier boutique for customer credit and repayment.
The product is framed as a way to make contributions and commitments easier to document and retrieve.
