ERPNext Setup and Customization

I'm looking for someone with previous experience with ERPNEXT to upload inventory components and BOM into the cloud version. Currently the inventory and BOM are in an excel speadsheet. We have over 1000 products that we assemble and close to 3000 components. Unit cost is calculated by purchase price + shipping cost * exchange rate + brokerage costs all devided by number of units included the price. To be clear, mapping the inventory and BOM is the easy part. I exported a sample of one product and the components were all there but the product SKU was not. Preference will be given to those with hands on experience with ERPNEXT. Please indicate if you have used ERPNEXT.
