Marii Credit is built for shops your customers already return to. Every dollar kept on the card is a guaranteed next visit, and the books stay clean: capped exposure, exact expected overage, coded redemptions.
Credit is redeemable only at your till. The change you would have handed over in sweets or IOUs now guarantees the customer comes back.
Small change, never a liability problem. The cap keeps outstanding credit a rounding line, not a debt book.
Credit given stays in the drawer, so your dashboard shows the exact expected overage per till, per shift, per device — the number finance ticks against the cash.
Every spend prints an R-code your POS discount total is checked against. Nothing leaks between the card and the till.
