Credit is a relationship tool: it keeps loyal customers coming back. It only works if it stays organised, because forgotten or unrecorded credit is how shops lose money without noticing.
Practical habits help more than any single tool: record it immediately, agree a clear limit and a date to settle, and review the list weekly so small debts get chased before they grow.
