How to buy assembly, packaging & fulfilment
Outsourced assembly and fulfilment are bought on cost per unit, but won or lost on quality, on-time delivery and traceability.
- 01Define the BoM and work instructions
Issue a controlled BoM, work instructions, torque values, test steps and packaging specification. Vague work instructions cause variable yield.
- 02Decide consignment model
Free-issued components vs full BoM ownership by the contractor changes pricing, risk and stock control entirely.
- 03Plan inspection and test
In-process checks, final test, packaging audit and outgoing sample plan should all be explicit before pricing.
- 04Agree logistics and fulfilment
Pack format, label artwork, courier, returns handling and inventory visibility should be in the contract, not the kick-off meeting.
- 05Lock data and reporting
Daily build numbers, defects per million, on-time delivery and any serial-number traceability should report into your ERP.
