Services Provided by Contract Manufacturing Service Provider

Contract manufacturing service provider typically work with customers in a wide range of industries with difference requirement and expectation. It offer a series of services, ranging from proof of concept and prototyping, global sourcing and purchasing, inventory control, wire harness, sub-assembly, and final assembly, panel wiring, modules integration  testing, product packaging, product support, updating of drawing and bill of material (BOM) and many more.

Definition of Inventory Method

In some applications, the contract manufacturing service provider simply assembles the wire harness and then ships the wire harness to the customer. In other applications, the contract manufacturing service provider will assemble the complete equipment, set the operational parameters, load software into memory, test the equipment, and update documentation and pack the equipment into a finished product that is shipped to the customer. Some customers choose to to provide all of the materials, such as cable and connectors, electronic and electrical components, controller, mechanical structure and fabricated parts and etc that are required for the job. And the contract manufacturing service provider assemblies all parts together, performs any required testing, and ships the finished product to the customer. Such arrangement is generally considered as inventory provided on a consignment basis where the contract manufacturing service provider basically provides labor and expertise only. Some customers may choose to provide a portion of the materials required, such as specialty or high cost controller, proprietary parts such as custom build printed circuit boards, etc. and rely on the contract manufacturing service provider to purchase the remainder of the components needed to assemble the equipment  Most contract manufacturing service providers prefer to use their own sourcing and purchasing expertise through their extensive contacts inventory where applicable to provide all of the required materials as per customer’s particular project BOM list. This method is generally considered as inventory provided on a turn-key basis.

Contract Manufacturing Price Estimation

But before any of this can happen, the contract manufacturing service provider must provide a pricing estimate to the customer for the project. Other then the quantity commitments, production schedule, annual usage quantity, and quantity per order, this pricing process also requires a detailed BOM list and drawing from the customer. The BOM should define all of the components required along with the approved vendor and vendor’s part number for each component. This information allows the contract manufacturing service provider to determine material availability, minimum order quantity (MOQ), packaging size, lead time, cost for each component based on the quantities and vendor information and etc. The BOM also provide information (when match with drawing) to allow a technical review to determine the amount of labor and tooling required to manufactured and assembled each parts together to form the final product.
