Most ERP systems provide a sales kit functionality. Some simply explode the kit into sales orders lines. Some offer the ability to keep the kit as a line but explode it for allocation, picking and shipment. Some offer the ability to modify the kit components on the fly; e.g. to substitute an item of the kit. The non-stock kit in Acumatica does not reduce availability of the components either as SO Prepared or SO Booked making it impossible for a user to know if a kit is short.
