Not a generic ledger squeezed onto a phone. Every flow is shaped around how small Nigerian businesses sell, restock, collect debt and make decisions during a real trading day.
Sales, costs, expenses, tender mix, debts and stock come together so revenue never pretends to be profit.
Track products in practical base and bulk units, catch low stock early, and plan restocking around available cash.
Growth Brain turns the records already on your phone into a short list of actions for pricing, debt and stock.
