A range review that ignores quality control process will often produce a confident decision and a disappointing quarter on the Citrus Lite.
Cash flow is the quiet constraint behind quality control process: the cheapest option is rarely the one that frees the most working capital.
Why quality control process matters on the Citrus Lite
Incoming inspection sampling catches most issues before they reach shops.
Shops that receive a short briefing on quality control process convert noticeably better than shops that only receive stock.
Functional testing of a sample from each batch is standard practice.

Commercial terms
Lead times are a function of component availability as much as factory capacity, so buffers should reflect both.
Payment history is the single most reliable route to better terms, more than total annual volume.
