Product Assemblies
An Assembly (Kit) is a single Product ID which refers to several separate components. When you enter an Assembly onto a Sales Order, the inventory is affected for all of its component parts, although only the Assembly prints on the Sales Invoice.
You may recognize that you can also use a combination of Blind Line Items to achieve a similar effect, but an Assembly is better because the profitability of an Assembly is divided equally among each of its components. In other words, if you enter a single line for, lets say, a brochure and then three Blind Line Items for the costs you do not wish to see, the sales history reports would be skewed. While the overall profitability of the order would be correct, 100% of the profit would be on the Brochures line item and each of the Blind Line Items would be a complete loss.
Using an Assembly allows you to indicate a separate sale price and cost for each component, while printing only the Assembly on the customers invoice.
Your invoices must be specifically designed to support this feature.
