What is a welding invoice?
A welding invoice covers three separable things: the time the welder spent, the metal that went into the work, and the equipment that had to be on site to do it. Keeping them apart is what makes the invoice readable — labor hours are checked against a job log, material is checked against a mill or supplier ticket, and rig time is checked against the day the truck was there.
Shop work and field work should not share a rate. Field work carries travel, setup, weather and the certainty of waiting on someone else, and most fabricators bill it fifteen to forty percent above the bench rate. Show both rates on the invoice rather than averaging them into one number, and the difference stops being a negotiation.
Material is billed by weight and grade — plate, tube, angle, stainless, aluminum — with the size and quantity stated. Consumables such as wire, rod, gas and grinding discs are usually a flat percentage of labor or a per-hour charge; either is fine, as long as the invoice says which.
What to include
Everything below is already in the generator above — this is what each part is for.
Job and PO reference
The job name, drawing number and the customer PO the work was authorised under.
Shop labor hours
Bench and fabrication hours at the shop rate, with the dates worked.
Field labor hours
On-site hours at the field rate, with travel and setup shown separately.
Material by weight and grade
Plate, tube and section with size, quantity and grade, priced from the supplier ticket.
Consumables and gas
Wire, rod, shielding gas and abrasives, as a per-hour charge or a percentage of labor.
Certification and inspection
Welder cert numbers, WPS reference and any third-party NDT or inspection passed through.

Rates, material and getting paid on field work
Set two labor rates and publish them
One shop rate, one field rate. The field rate covers travel, generator fuel, setup and the hours lost waiting for a crane or a permit. Quoting a single blended rate means every field job quietly subsidises the shop, and the customer never sees why the price moved.
Bill material from the ticket
- Show weight, grade and size for each stock item, not a lump "steel" line.
- State your markup policy — cost plus a fixed percentage is standard and defensible.
- Pass through mill test reports when the job needs traceability; reference them on the invoice.
Rig time is a real cost
A welding truck with a machine, gas, leads and fuel costs money for every hour it sits at a customer site, whether or not an arc is struck. Bill rig time or a mobilisation fee as its own line. If the crew waited three hours for the fitter, that is a line too — waiting time billed at the field rate.
Progress-bill anything over two weeks
Fabrication jobs tie up material money before a single invoice goes out. On longer jobs bill a deposit against material at order, a progress payment at fit-up, and the balance at delivery or final inspection. Net 30 on the whole job means financing your customer for the length of the build.
Three mistakes that delay payment
One rate for shop and field
Field work costs more to deliver. A blended rate hides it and makes every quote a fight.
Material as a single "steel" line
Weight and grade let the customer check the price. A lump sum invites a phone call.
No PO or drawing number
Shop accounting cannot match the invoice to an authorisation, so it sits in a pile.
