FastClose has been working with our customers to build a Bill of Materials module for Epicor. We would be interested in feedback as there seem to be several things that customers require. For example, being able to get an online complete cost roll up (materials, labour and burden) before you sell a product and seeing if you have the materials in stock for all the components that make up the BOM. We also extract values for  LIFO, FIFO, average, and standard costing. Please fill in the contact us form or email Nick.Gomersall @ FastClose.uk if you have any suggestions or would like further information.
