Accounting and stock for vendors who sell out of a vehicle — in type large enough to read in sunlight. • Works offline. Write an invoice with no signal; it sends itself when the network returns. • Sell in a few taps — cash, credit, or a part payment. • Scan a barcode or search by name. Works offline too. • The vehicle is a warehouse: move goods to the van and the stock follows. • A statement per customer and supplier, with the balance owed. • Reports: sales, receipts, expenses, profit, and what is running low. No accounting jargon, no complicated screens.
