Every cost category explained — equipment, shipping, duties, certifications, and the hidden fees most suppliers won’t tell you about. Free downloadable checklist included.
① Service Fee
Our design and procurement management fee — 5%-10% of equipment cost, listed as a separate line item so you always know what you’re paying for our work versus what goes to the factory.
② Equipment Cost
Factory-direct pricing with zero markup from us. You see every supplier invoice. We help you compare quotes from 2-3 manufacturers to find the best value for your specifications.

For urgent shipments, samples, or emergency replacement parts. $3-8/kg depending on weight and destination. Used selectively when speed justifies the premium.
