Canteen Billing That Runs on Prepaid Balances.

A canteen lives on credit. Staff eat today, the company pays at month end, and somebody keeps a register of who had what. When the totals do not match the cheque, the register loses the argument.

Tournant keeps a balance per person and per company account. Every meal draws it down, every top-up adds to it, and each one can see their own balance, so month end is a statement rather than a dispute.
