Why does low-volume purchasing become a problem?

1. Minimum pack quantity. Components are produced and shipped in fixed minimum packs — a few hundred to tens of thousands of pieces for transistors, capacitors, resistors and microprocessor chips. When a company builds a prototype it may need only a handful of each part but still has to buy a full minimum pack, which causes serious waste and keeps R&D and trial-production costs high. Small parts of any kind face the same minimum-pack problem.
2. Minimum batch quantity. Beyond minimum packs, low-volume buyers also run into minimum batch requirements. Because of process, equipment or transport constraints, production often cannot run at the smallest unit and must use a fixed base quantity; otherwise the product simply cannot be made. Products with such process or equipment constraints therefore face a minimum batch problem when bought in small quantities.
3. Minimum cost. For some products there is no minimum batch requirement, yet in certain processes the cost of making one piece equals the cost of making several within a minimum quantity. The unit cost of a single piece can then be hundreds of times that of a batch. This is common in manufacturing: cost stays flat up to a minimum base quantity, and batch cost scales with multiples of that base. Low-volume purchasing therefore also faces a minimum-cost problem.
4. Sample demand during design and prototyping. Every manufacturer of electronic products must go through sample testing and part selection, comparing, evaluating and testing parts in different packages and with different functions in order to finalise the design.
5. To address low-volume purchasing, Yachuang has opened a fast lane for small orders: a simplified settlement process, no minimum order quantity, and the option to buy every line on a parts list or BOM in one go. Payment is simple and safe, including cash, bank transfer, Alipay and WeChat Pay.
