Mobile Welding Billing Best Practices
Bill Rig Time From Gate to Gate
Clearly state minimum 2-hour or 4-hour callout charges for mobile rig dispatch to prevent losing money on tiny 15-minute fixes.
Itemize Steel & Wear Plate Weights
List exact steel dimensions and alloy specs (e.g. A36 structural tube, AR400 plate) to justify high material bills.
Document Fire Watch Times
If OSHA required 30-minute post-weld fire watch is performed, include that time in your billable hours.
Frequently Asked Questions
How do mobile welders charge clients?
Most mobile welders charge a rig callout fee ($100-$200) plus an hourly rate ($95-$165/hr) with a 2-hour minimum.
What should be on a structural welding invoice?
AWS welder certification ID, steel heat numbers, electrode type (E7018 / ER70S-6), fire safety disclaimer, and payment terms.
Is welding labor subject to sales tax?
Fabrication of new items sold to a client is taxable; repair of real property (like gates fixed in ground) is often non-taxable labor.
Can I require deposits for steel fabrication?
Yes, 50% deposit is mandatory to purchase raw steel bundles and specialty fittings before cutting in the shop.
