How Many Sales Reps Do I Need to Hire for My Welding Supply Company?

I’ve been doing this for 25 years, and the number one mistake I see welding supply owners make is guessing how many reps to hire. They pick a number from the air—“I think we need three more guys”—and then wonder why the revenue didn’t show up. That’s not strategy. That’s a wish.

Here’s what actually happens. You don’t guess headcount. You back into it from the gap between where your revenue is and where you want it. The formula is simple: reps to hire = (net-new revenue you need / productive capacity per ramped rep) + backfills for attrition, adjusted for ramp time.

Work it in order. Start with current revenue and goal revenue. Subtract the growth your existing accounts produce on their own at your net revenue retention. What’s left is the net-new number your reps must generate.

Let me walk you through a real example. Say your welding supply company is at $9M in revenue and wants $13.5M. You run 106% NRR—that means your base carries itself to $9.54M without lifting a finger. That leaves roughly $3.96M of net-new to sell.

Now, a fully ramped rep produces about $900K a year at realistic attainment—not the paper quota, what they actually deliver. So you need about 4.4 rep-years of capacity.

But here’s where the guessing kills you. A rep hired today is not productive for the first few months. They’re learning your product line, building pipeline, figuring out which welding wire goes where. In this business, the ramp is real—deep SKU catalog, application knowledge, gas cylinder rentals, capital equipment. So you add ramp time.

Then add attrition. Lose 18% of a 7-rep team and you must backfill 1 to 2 just to stand still.

Net it out: you’re hiring roughly 6 to 7 reps, started early enough to ramp before you need the production.

Welding supply blends consumable wire and electrode reorders, gas cylinder rentals, and capital equipment (machines, automation). Your rep manages recurring consumable accounts while hunting equipment deals. The math is the same, but the mix matters—large share of recurring revenue means your existing team already defends the base.

I built a free Recruiting Calculator that runs this whole model. Current and goal revenue, current and goal NRR, ramp time, training length, attrition, current headcount—all in. Reps-to-hire and start dates out. No login, no spreadsheet, seconds.

Here are the ten tools that solve this, ranked. PULSE is first because it’s free and built around this exact math.
