🔴 Why Procurement & Engineering Teams Struggle with Sprocket Sourcing
You’ve seen it before — broken promises on lead times, inconsistent hardness, and hidden fees that blow up your TCO. Here are the top 5 pain points our clients came to us with:
“Quotes looked good, but after tooling, packaging, and freight surcharges, the final invoice was 23% higher.” — US purchasing manager
43% of supply chain disruptions in 2025 were due to logistics delays. Every day of downtime costs OEMs $22k–$85k.
Poor heat treatment leads to early wear, elongation, and tooth breakage. One German client reported 4x more replacements than expected.
Missing CE, RoHS, or ISO 9001 docs can block customs and delay your time-to-market by weeks.
Time-zone differences, unclear specs, and slow RMA processes create frustration and lost trust.
👉 You need a partner who eliminates these risks — not adds to them.
