I am a programmer and recently posted an application on the AppStore for iPad store management. It tracks customers, suppliers, products, sales, commissions, inputs, outputs, accounts payable, accounts receivable and generates reports.
All this offline on iPad using SQLite as database.
Is available on the AppStore for $ 9.99 U in 2 languages, English and Portuguese.
