How Much Does Field Service Software Cost? The Real All-In Math

You pull up three pricing pages, line up the numbers, and pick the cheapest. Two months later your card gets hit for triple what you expected, and you can't figure out where it came from.

Here's where: the sticker price is the smallest part of what you'll pay. Per-seat fees, payment processing, and à la carte add-ons do the real damage — and none of them are on the headline you compared.

So how much does field service software cost? This post answers it honestly — not with a number, but with the math to build your own true monthly bill. We'll work through real examples for a solo operator, a 6-person crew, and a 10-person crew, so you can see exactly how the cheapest sticker price often turns into the most expensive bill.

A note on the numbers: any platform-specific rates referenced here reflect publicly listed pricing as of June 2026. The worked examples are illustrative — plug in your own plan, headcount, and card volume, and confirm current rates on each vendor's pricing page.

The Sticker Price Is a Trap

Every FSM platform — Jobber, Housecall Pro, and the rest — leads with a low base number. Jobber starts around $29/month. Housecall Pro's entry tier sits higher. These numbers are real, and they're nearly meaningless on their own, because they only cover a slice of what you'll actually pay.

Your true monthly cost is four numbers stacked:

Base subscription — the headline price
Per-user / per-seat fees — for every team member over your plan's cap
Payment processing — a cut of every card and bank payment you take
Paid add-ons — features the base plan doesn't include

Ignore any one of these and your comparison is fiction. The base subscription is almost never the biggest line on the bill — and it's the only one the pricing page shows you clearly.

The Four Numbers, Explained

Base subscription

The plan tier you sign up for. Ranges from ~$29/month for an entry plan to $300–500+/month for higher tiers with more included seats and features. Easy to compare, least important.

Per-user fees

Most plans include a fixed number of users. Go over and each seat costs extra — Jobber charges about $29 per additional user per month. Housecall Pro bundles users into tiers, so adding people can bump you to a pricier plan. Either way, this fee grows as you hire. Count the seats you'll have at your busiest, not today.

Payment processing

This is the one that does the quiet damage, because it scales with your revenue, not your headcount.

Credit/debit cards: ~2.9% + $0.30 per transaction
ACH bank transfers: ~1%
Instant payout (same-day money instead of waiting): often +1%

These come out of every payment, every month, on every platform — including ours. For most trades businesses, processing is the single largest software-related cost, and it never appears in a side-by-side comparison.

Paid add-ons

Features you might assume are standard but aren't. On Jobber, things like the AI Receptionist (~$99/mo), Marketing Suite (~$79/mo), and standalone Reviews or Campaigns (~$29–39/mo) are à la carte. Housecall Pro gates its marketing tools behind higher tiers. Only count the ones you'll genuinely turn on — but count them honestly.

Worked Example 1: The Solo Operator

One person, no crew. Maybe $15,000/month in card payments.

| Line item | Monthly cost | |---|---| | Base plan (entry tier) | ~$29 | | Per-user fees (none — solo) | $0 | | Processing (~$15k cards @ 2.9% + $0.30) | ~$450 | | Add-ons (skipping them) | $0 | | Total | ~$479/month |

Notice what just happened: the $29 plan is 6% of your actual bill. Processing is 94% of it. For a solo op, the subscription you obsessed over barely matters — the processing rate is the entire game. A platform with a 0.3% lower card rate would save you ~$45/month, far more than any difference in sticker price.

Worked Example 2: The 6-Person Crew

A small landscaping or HVAC shop. Six people, ~$40,000/month in card volume, running one marketing add-on.

| Line item | Monthly cost | |---|---| | Base plan (mid tier, ~5 users) | ~$149 | | Per-user fee (1 extra seat @ $29) | ~$29 | | Processing (~$40k cards @ 2.9% + $0.30) | ~$1,180 | | One marketing add-on | ~$79 | | Total | ~$1,437/month |

Here the subscription and per-seat fees together ($178) are about 12% of the bill. Processing is over 80% of it. If you'd picked this platform because its base price was $40/month cheaper than a competitor's, you optimized the number that mattered least.

Worked Example 3: The 10-Person Crew

A growing shop. Ten people, ~$80,000/month in card volume, two add-ons.

| Line item | Monthly cost | |---|---| | Base plan (higher tier, ~10 users) | ~$299 | | Per-user fees (within cap) | ~$0–87 | | Processing (~$80k cards @ 2.9% + $0.30) | ~$2,360 | | Two add-ons (marketing + AI) | ~$178 | | Total | ~$2,840–2,925/month |

At this size the subscription plus add-ons run ~$480–565 — real money, but still under 20% of the bill. Processing is ~$2,360 of it. Shaving 0.2% off your card rate here saves ~$160/month, $1,900/year. No subscription discount comes close.

The Pattern: Processing Eats Everything

Across all three examples, the lesson repeats: the more you grow, the less the subscription matters and the more processing dominates. Yet almost every "cheapest FSM software" article ranks tools by sticker price alone.

That's why a $29 plan and a $59 plan can cost the same in practice — or flip — once you add seats and processing. We dug into exactly how this plays out on one platform in Jobber's hidden fees, and how it shapes the whole switching decision in our guide to Housecall Pro alternatives for small business.

How to Build Your Real Monthly Bill

Do this for every platform you're comparing. Five minutes of math beats months of overpaying.

Write down the base plan at the tier that actually fits your team size.
Add per-seat fees for every user over the cap — at your peak-season headcount, not your slow-month one.
Calculate processing: your monthly card volume × the card rate, plus ACH volume × the ACH rate. This is your biggest variable — get it right.
Add only the add-ons you'll switch on. Be honest, not optimistic.
Sum it, then compare totals — not sticker prices.

Run two or three platforms through this and the "cheapest" one usually changes. For a trade-specific walkthrough, see our Jobber vs Housecall Pro comparison for landscaping.

What This Means for Choosing Software

Three takeaways once you've done the math:

Weight the processing rate heavily. It's most of your bill. A small percentage difference dwarfs any subscription discount.
Watch per-seat fees if you're growing. A platform that's cheap at 4 people can be the expensive one at 10.
Only pay for add-ons you'll use. Bundled-in beats à la carte when you're actually going to use the feature — and "free" features you ignore aren't a selling point either.

We'll be straight about our own pricing: processing fees apply to WorkSlate too — that's how card payments work for everyone. What we don't do is hide the core tools behind add-ons. Estimates, invoicing, scheduling, and a customer portal are on every plan, so the number you compare is the number you pay.

The Short Version

How much does field service software cost? Not what the pricing page says. Your real bill is:

Base plan — the smallest piece, and the only one advertised clearly
Per-user fees — grows as you hire (Jobber ~$29/seat; Housecall Pro bumps you up tiers)
Processing — ~2.9% + $0.30 per card, usually most of your bill
Add-ons — only count what you'll use

Build the four-number total for every option before you sign. The cheapest sticker price is frequently the most expensive software.

WorkSlate puts estimates, invoicing, scheduling, and a customer portal on every plan — no add-ons to unlock the basics. See our pricing and build your real monthly bill.
