What Clients Say

From engineers and managers who have worked directly with our team

★★★★★

"We had a failed S7-300 CPU during a live production run. WhizServe had a remote engineer on the line within the hour. Back up in 4 hours. Impressive."

David H. Maintenance Manager, Food Manufacturing

★★★★★

"Fixed pricing was the deciding factor for us. Every other quote came back with open-ended day rates. WhizServe scoped it properly and delivered exactly what was agreed."

Sarah R. Automation Engineer, Automotive Tier 1

★★★★★

"The as-built documentation alone was worth the contract. Most contractors hand over working code with no comments. WhizServe handed over code I can actually maintain."
