Top 10 Sales Apps for the New iPad
Quick Sale Lite
Quick Sale Lite simplifies your sales paperwork. You use it to create, manage and email invoices, track inventory, payments, balances, reports and so forth; it sends out updates in printable PDF format.
It can handle fairly complex inventories, with photos, track stock levels and do all sorts of stuff usually handled by high-priced sales order tracking software. The free version is limited to five invoices at a time, but that should be enough for many businesses.
