Need an app with following functions: - Create Inventory Assemblies / Product Bundles with sub-products, for example I want to create the product/assembly "Computer Base System” that is composed of several components/sub-products: A “Case”, a “Motherboard” and 10 screws. - The price for the assembly (e.g. the "Computer Base System") is automatically calculated as the sum of the price of all sub-products. - Synchronize product data with QuickBooks product data. - Create quotes, sales orders, and invoices displaying all sub-products in the assembly. - Synchronize quotes, sales orders, and invoices with QuickBooks.
