Managing suppliers and subs without the drama
Your suppliers and subs are the part of the business that breaks at the worst possible moment unless you manage it.
Two of everything critical
A single supplier for the parts you can't run without is a future emergency. Qualify a backup before you need them, and run a real order through them at least once a quarter.
Pay on time, every time
Being the customer who pays in 7 days when everyone else takes 60 is the cheapest competitive advantage available. You get priority on shortages, better terms, and warned about price increases before they hit.
Annual price review
Suppliers raise prices quietly. Once a year, pull your top 10 line items, compare to two alternatives, and have the conversation. Most owners save 3-7% on materials by doing this once.
Take your version of this question further
