Welding Invoice Template: Mobile Rates, Materials and Gas

Quick answer: A welding invoice lists your business details, the client and job location, a unique invoice number, a description of each weld repair or fabricated item, labor hours and rate, any mobile trip or call-out charge, metal stock with sizes and quantities, consumables and shielding gas, deposits received, tax where it applies and the balance due with payment terms.

Welding jobs come in two very different shapes. Some are quick mobile repairs: a cracked trailer hitch, a broken gate, a split loader bucket on a farm. Others are fabrication jobs that take days in the shop. Both need a welding invoice that shows what you did, what you supplied and how you priced it, because clients rarely see the gas, wire and grinding discs that went into a clean bead. You can build one in our free invoice generator in a few minutes.

This guide covers what to include, 2026 mobile welding rates, how to bill materials and gas, trip charges and minimums, fabrication jobs, a worked example with real totals, tax, and common mistakes.

What a welding invoice should include

A welding invoice should be specific enough that someone who was not on site can see what was repaired or built. Include:

• Your business details: name, address, phone, email and logo. If the client asked for certified work, note the relevant certification on the invoice or attach a copy.
• Client and job location: the billing name and the site address, farm, yard or vessel.
• Invoice number and date: sequential, such as WLD-2026-0211. The invoice number generator can suggest a format.
• Work description: the item, the problem and the fix, such as "Re-weld cracked trailer tongue, add 2 x 2 in gusset plates".
• Process and material: MIG, TIG or stick, and steel, stainless or aluminum, when it affects the price.
• Labor: hours and rate, or a fixed price for fabrication.
• Trip or call-out charge: for mobile welding.
• Metal and parts: tube, plate, angle, pipe, hinges or fittings, with sizes and quantities.
• Consumables and gas: wire, rods, discs and shielding gas, itemized or as a set charge.
• Payments and terms: deposit as amount paid, due date and accepted methods.

For repeat fleet or farm clients, add the asset ID or equipment description in each line. It helps their maintenance records and makes the invoice easier to approve.

Welding rates in 2026: shop vs mobile

There is no national standard rate for welding, and published guides disagree. The ranges below come from 2026 cost and pricing guides. Many of them are marketing pages rather than surveys, so treat these as rough illustrations and price from your local market and your costs.

Type of work	Common pricing	Typical 2026 range (varies widely)	Invoice line example
Shop welding and repairs	Hourly	Roughly $60 to $125 per hour in US consumer guides	Shop weld repair, mower deck, 1.5 hrs
Mobile welding	Hourly plus trip charge or minimum	Usually above shop rates; one to two hour minimums are common	Mobile welding labor, on site, 2.5 hrs
Structural or certified work	Hourly or per job	Often quoted above general rates; some guides cite $175 to $250 per hour for certified structural work	Certified structural weld, beam connection
After-hours or emergency	Premium hourly rate	Commonly a significant premium over standard rates	Emergency call-out, Sunday, 2 hrs
Fabrication	Fixed price per item or job	Quoted per drawing, metal and finish	Fabricate steel handrail, 12 ft, per drawing

Wage data helps you sanity-check your rate. The BLS occupational outlook for welders, cutters, solderers and brazers reports a May 2025 median wage of $25.84 per hour. A self-employed welder's billed rate is far higher than that because it must also cover the rig, welder and generator, insurance, gas cylinder rental, fuel, unpaid quoting and drive time, and profit. Our guide to overhead costs shows how to build those costs into an hourly rate.

Mobile welding: trip charges and minimums

Mobile welding rates need to account for the time before the first arc. There are three common ways to do it:

1. Flat trip or call-out fee: one fixed charge per visit, sometimes tiered by distance. Simple and easy to explain.
2. Minimum charge: for example, the first hour or two billed regardless of job length. This protects you on five-minute tack jobs.
3. Travel time billed: drive time at your full or a reduced rate. Fair on long rural trips but harder for clients to predict.

Whichever you choose, say it on the phone or the quote, and show it as its own line on the welding invoice. Clients accept a trip charge they were told about; they dispute one they were not. If you track business miles for tax, keep a simple mileage log with dates, destinations and purpose, and the guide to reimbursable expenses on invoices covers billing travel costs back to clients.

Billing materials and gas on a welding invoice

Materials and gas are where welding invoices most often get questioned. Clients see a bead that took twenty minutes and a line for consumables they did not expect. Make the policy clear:

Metal stock and parts

List each item with size and quantity: "2 x 2 in square tube, 11 ga, 20 ft" or "1/4 in plate, 12 x 12 in". Metal prices move, so for fabrication quotes it is worth stating how long the price holds. Billing at cost plus a markup is common, so decide the percentage before you quote.

Consumables and shielding gas

Wire, rods, tungsten, grinding and flap discs, and shielding gas such as argon or argon-CO2 mixes are real costs. You can:

• build them into your hourly rate,
• charge a flat shop-supplies line per job, or
• itemize them on large jobs where gas and filler use is significant, such as long TIG runs on stainless or aluminum.

An itemized invoice works well for big fabrication jobs, while small repairs usually look cleaner with one consumables line. Our labor and materials invoice guide shows layouts for both.

Sample welding invoice walk-through

Here is an illustrative example. A mobile welder repairs a cracked tongue on a utility trailer at a customer's property. The job takes 2.5 hours on site at $110 per hour, plus a $95 trip charge. The welder supplies 20 feet of square tube for reinforcement and charges a flat consumables and gas line. In this example the welder works where the invoice carries no sales tax for this job. Check your own rules.

Description	Qty	Rate	Amount
Mobile service trip charge	1	$95.00	$95.00
On-site welding labor, MIG, trailer tongue repair (hrs)	2.5	$110.00	$275.00
Square tube, 2 x 2 in, 11 ga steel (ft)	20	$4.50	$90.00
Consumables and shielding gas	1	$35.00	$35.00
Total			$495.00
Paid on site by card			-$495.00
Balance due			$0.00

The labor and trip charge come to $370 and materials and consumables to $125, adding up to $495. Because the client paid on the spot, the same PDF works as a receipt; see our paid invoice template guide for marking invoices paid.

To build it in our generator:

1. Open the free invoice generator and choose your country preset, such as the US invoice generator.
2. Add your logo, business name and contact details.
3. Enter the client name, job location and invoice number.
4. Add the four line items. Use 2.5 as the quantity for labor hours.
5. Set the tax rate only if the job is taxable where you work; the generator applies one rate to the invoice.
6. Enter $495 in the amount paid field so the balance due shows zero, and note the payment method.
7. Download the PDF and email or text it to the client.

Fabrication jobs, deposits and change orders

Fabrication is closer to contracting than repair. Gates, railings, brackets, trailers and custom frames are usually quoted at a fixed price against a sketch or drawing. A typical flow:

1. Quote with a drawing: dimensions, material, finish and installation. Our estimate template guide helps you set this out.
2. Take a deposit for metal: enough to cover stock that cannot be returned. See our guide to deposit invoices.
3. Record changes: a taller railing or an extra gate latch is a change order, approved before you cut.
4. Final invoice: list the item, outsourced finishing such as powder coat or galvanizing, delivery and installation, then subtract the deposit.

If you weld on construction sites for a general contractor, expect PO numbers, net 30 terms and possibly lien waivers. Agree those requirements before the first invoice goes out.

Fleet, farm and industrial clients

Repeat commercial clients are the backbone of many mobile welding businesses: trucking fleets, farms, construction equipment yards, quarries and manufacturers. They usually value speed and reliability over the lowest price, but they also expect paperwork that fits their systems.

• Purchase orders: many businesses will not pay an invoice without a PO number. Ask for it when the call comes in and put it in the invoice header or notes.
• Asset or unit numbers: list the truck number, trailer ID or machine serial in each line description, so the client can charge the cost to the right piece of equipment.
• Itemized time: fleet managers often want start and finish times and the hours per unit, even on small jobs.
• Payment terms: net 30 is common for business clients. Price your mobile welding rates with that wait in mind, and agree terms in writing before anything longer.

If one client calls you out several times a month, ask whether they prefer one invoice per job or a single monthly invoice listing every visit. A monthly invoice with a line per call-out, each with the date, unit number, hours and materials, saves their accounts team time and gets you paid in one go. Keep each line as detailed as a standalone welding invoice would be, so nothing is queried.

Emergency and after-hours work

Breakdowns rarely happen at convenient times. If you take night, weekend or holiday calls, set a clear premium rate or call-out fee and tell the client before you set off. Show it as a separate line, such as "After-hours call-out, Sunday", so the client can see exactly what the premium added.

Warranty and weld documentation

Some clients ask what happens if a repair fails. State your workmanship policy on the quote, for example that you will re-weld a failed repair at no labor charge within a set period, excluding damage from overloading or misuse. Add a one-line summary in the invoice notes. For structural or code work, keep a record of the process, filler metal and welder certification used, and attach it if the client or inspector needs it. That record costs you a few minutes and can settle a dispute months later.

Tax on welding services

Sales tax on welding depends on what you are selling. In many US states, a fabricated item you sell is taxable as goods, repair labor on personal property may or may not be taxable, and welding that becomes part of a building usually follows contractor rules. Read our overview of sales tax on US invoices, and use the sales tax calculator where it applies. In the UK, VAT applies once you are registered. This is general information, not tax advice; check with a qualified adviser.

Common welding invoice mistakes

• Surprise trip charges. Tell the client before you drive out, then show the charge as its own line.
• "Welding, $495". Describe the item, the fault and the fix.
• No metal sizes. Clients cannot check "steel, $90". Give the profile, gauge and length.
• Unpriced extras on fabrication. Extra brackets or a design change need approval first.
• Ignoring gas and consumables. If they are not in your rate, they must be on the invoice, or they come out of your profit.
• No receipt for cash or card jobs. Issue a numbered invoice marked paid every time.

Create your welding invoice

A good welding invoice shows the repair or item, the hours, any trip charge, the metal and the consumables, so the client sees exactly why the bead cost what it did. Agree your mobile welding rates and minimums before you drive out, itemize materials and gas, and record every payment.
