List your products once with their selling and cost prices. Then log each sale — product, quantity, and the price it actually sold at (so discounts are captured honestly). The Dashboard gives you total sales, total profit, margin and transaction count, a best-sellers table with data bars, and a monthly sales trend. Because profit uses your product cost, a big sale at a deep discount won't fool you.
It's the analytics layer a shop owner actually asks for — what's selling, what's making money, and which way the trend points — with the maths done for you and the formulas locked. Opens in Excel or Google Sheets; keep it on your phone and log sales as they happen.
When you'd rather sales tracked themselves, Biashara Yangu records sales by voice or photo and keeps this exact picture for you, free.
