Every job management software company shows you the price per user per month. £29/user. £37/user. £39/user. It sounds reasonable. One user, one price. Simple.
Until you hire your fourth person. Then your fifth. Then you realise that adding an apprentice costs £39/mo in software before they've earned you a penny.
Per-user pricing is the default in field service software. It's also the worst pricing model for growing trade businesses. This post shows you the maths.
The maths nobody shows you
Let's compare the actual monthly cost of popular platforms at different team sizes:
5 users (small team)
| Platform | Per-user price | Monthly total |
|---|---|---|
| Powered Now | £32/user | £160 |
| Tradify | £37/user | £185 |
| Workever | £39/user | £195 |
| Commusoft | ~£80/user | ~£400 |
| BigChange | £80/licence | £400 |
| Muster Starter | Flat rate | £179 |
At 5 users, Muster is mid-range. Nothing dramatic yet. But watch what happens as you grow.
10 users (growing team)
| Platform | Per-user price | Monthly total |
|---|---|---|
| Powered Now | £32/user | £320 |
| Muster Growth | Flat rate | £349 |
| Tradify | £37/user | £370 |
| Workever | £39/user | £390 |
| Commusoft | ~£80/user | ~£800 |
| BigChange | £80/licence | £800 |
At 10 users, Muster is cheaper than Tradify, Workever, Commusoft, and BigChange. Only Powered Now is cheaper — and it has no GPS, no AI, no RAMS, no customer portal.
20 users (established firm)
| Platform | Per-user price | Monthly total | Annual total |
|---|---|---|---|
| Muster Scale | Flat rate | £599 | £7,188 |
| Powered Now | £32/user | £640 | £7,680 |
| Tradify | £37/user | £740 | £8,880 |
| Workever | £39/user | £780 | £9,360 |
| Commusoft | ~£80/user | ~£1,600 | ~£19,200 |
| BigChange | £80/licence | £1,600 | £19,200 |
At 20 users, every per-user platform is more expensive than Muster. Commusoft and BigChange cost nearly 3× as much.
30 users (large team)
| Platform | Monthly total | Annual total | vs Muster |
|---|---|---|---|
| Muster Scale | £599 | £7,188 | — |
| Powered Now | £960 | £11,520 | +£4,332/yr |
| Tradify | £1,110 | £13,320 | +£6,132/yr |
| Workever | £1,170 | £14,040 | +£6,852/yr |
| Commusoft | ~£2,400 | ~£28,800 | +£21,612/yr |
| BigChange | £2,400 | £28,800 | +£21,612/yr |
At 30 users, you'd save £21,612 per year by using Muster instead of Commusoft or BigChange. That's a deposit on a van. That's a full-time apprentice's salary. That's your entire marketing budget for a year.
The hidden tax on growth
Per-user pricing creates a tax on hiring. Every new team member costs you money before they generate any revenue.
Example: hiring an apprentice
| Cost | Per-user (Tradify) | Flat rate (Muster) |
|---|---|---|
| Apprentice salary (year 1) | £14,000 | £14,000 |
| Employer's NI + pension | £2,800 | £2,800 |
| Van costs | £3,000 | £3,000 |
| Tools | £1,000 | £1,000 |
| Software licence | £444/yr | £0 |
| Total cost to hire | £21,244 | £20,800 |
That £444/yr software cost might seem small. But multiply it across every hire, every year, and it compounds. At 10 employees, Tradify costs £4,440/yr. At 20, £8,880/yr. At 30, £13,320/yr. Muster stays at £7,188/yr regardless.
Why software companies use per-user pricing
Per-user pricing maximises revenue for the software company, not value for you. Here's why they do it:
-
Revenue scales with your success. You grow, they earn more. Your success funds their growth — at your expense.
-
It's easy to justify at small scale. "Only £37 per user" sounds cheap when you're starting. By the time you have 15 users, you're locked in and the switching cost feels too high.
-
It discourages full adoption. When every licence costs money, businesses limit who gets access. The apprentice doesn't get a licence. The office admin shares a login. Half the team isn't using the software properly.
-
It creates upsell opportunities. "You've hit your user limit — upgrade to the next tier" is a conversation they love having.
What flat-rate pricing changes
With flat-rate pricing:
-
Every team member gets access. No debates about who "needs" a licence. The apprentice, the office admin, the subcontractor — everyone uses the system.
-
Hiring decisions are pure business decisions. You hire when the person generates more revenue than their salary costs. Software isn't a factor.
-
Your costs are predictable. Budget £179/mo, £349/mo, or £599/mo regardless of headcount. No surprises.
-
Software adoption is 100%. When there's no per-user cost, there's no reason not to give everyone access. Full adoption means better data, better scheduling, better communication.
The counter-argument
"Per-user pricing is fair because each user consumes server resources."
This is technically true and practically irrelevant. The marginal cost of one additional user on a cloud platform is pennies. Per-user pricing isn't about covering costs — it's about maximising revenue.
The real question is: does the software deliver more value to a 20-person team than a 5-person team? Usually not. The features are identical. The 20-person team just pays 4× more for the same product.
When per-user pricing makes sense
Being fair: per-user pricing isn't always wrong.
-
Solo traders — if you're a one-person operation, per-user pricing at £30-40/mo is often cheaper than a flat-rate plan. Muster Starter at £179/mo isn't designed for solo traders — it's designed for teams.
-
Enterprise software with per-user features — if each user gets dedicated resources (like a phone number, dedicated storage, or individual AI credits), per-user pricing reflects real costs.
-
You're testing software before committing — starting with 2 users at £37/mo is a low-risk way to try a platform. Just know that the cost will scale linearly if you grow.
The break-even calculation
At what team size does Muster become cheaper than per-user alternatives?
| vs Platform | Muster Starter (£179) breaks even at | Muster Growth (£349) breaks even at |
|---|---|---|
| Powered Now (£32/user) | 6 users | 11 users |
| Tradify (£37/user) | 5 users | 10 users |
| Workever (£39/user) | 5 users | 9 users |
| Commusoft (~£80/user) | 3 users | 5 users |
| BigChange (£80/licence) | 3 users | 5 users |
If you have 5 or more people who need access to your job management software, flat-rate pricing almost certainly saves you money. And Muster includes features (AI, GPS, RAMS, call recording) that per-user platforms charge extra for or don't have at all.
The bottom line
Per-user pricing looks affordable on a pricing page. It stops being affordable the moment you grow. The software company profits from your growth. You should profit from your growth.
Flat-rate pricing aligns your software cost with your business reality: as you grow, your revenue increases but your software bill stays flat. That's how it should work.
| Team size | Per-user total (avg £37/user) | Muster flat rate | You save |
|---|---|---|---|
| 5 | £185/mo | £179/mo | £6/mo |
| 10 | £370/mo | £349/mo | £21/mo |
| 15 | £555/mo | £349/mo | £206/mo |
| 20 | £740/mo | £599/mo | £141/mo |
| 30 | £1,110/mo | £599/mo | £511/mo |
At 30 users, you save £6,132/yr on software. What would you do with an extra £6,000?
Stop paying per head. Start paying flat.
Muster Starter: £179/mo for up to 9 users. Growth: £349/mo for up to 20. Scale: £599/mo for unlimited. Every feature included.
