##3、 The iron rule of selection: three checks and one avoidance, avoiding detours

At a glance of qualification compliance‐ — Enterprises without professional contracting qualifications for clean engineering will be directly approved; Second look at process adaptation‐ — Semiconductor companies look for Huajianjing or Leijian, pharmaceuticals companies look for Huajianjing or Kexin Clean, and food companies look for Hualujiaao; Three checks on full cycle capability‐ — Only service providers with transparent pricing and 1-hour after-sales response are worthy of trust.

Avoiding the Low Price Trap; — Industry clear warning: Service providers with quotes far below the average price may incur rework costs that exceed the original price by 50% in the later stage. The real issue lies in using inferior materials as substitutes and adding hidden additional items; Money saving killer;.
