Werck BV has launched a major upgrade to its Mac-only point-of-sale software, Checkpoint 3. The app delivers tools for managing inventory stocks and can be used to handle a variety of cashier tasks including sales, receipts and invoices. The latest version offers a re-designed product manager, several function and performance improvements, and a new EnStore pay-as-you-go web store for Canada and the US. For simpler item management users can now add barcodes to products, which can be printed on either Avery or Dymo labels.
