1. Work out your jobs-per-person ratio first
Monthly jobs ÷ people needing logins. This single number sorts the market: high ratio → per-user pricing (Tradify, Powered Now, Fergus) is efficient; low ratio → per-job pricing (ServiceM8) can be five times cheaper. Do this before reading any reviews, including ours; it eliminates half the market immediately.
2. Audit your devices
ServiceM8 is built for Apple; if your office is Windows and your vans carry Android, that's a hard constraint. Tradify and Powered Now publish iOS and Android apps. Whatever you shortlist, install the actual mobile app on your actual phone during the trial. The app is where the software lives or dies, in a van, with gloves, on 4G.
3. Write down your tax workflow before the demo
VAT-registered? On CIS, deducting or deducted? Making Tax Digital obligations? Write your quarterly routine down, then make the software do it on trial data. Powered Now submits VAT returns from its £32 tier; others hand off to Xero, Sage or QuickBooks, which is fine if the integration is on the tier you're buying. This is the check UK buyers most often skip and most often regret.
4. Price the tier your must-haves sit on
List your three non-negotiable features, then find the tier that actually contains them; that's the price you compare, not the homepage 'from' price. July 2026 examples: progress invoicing needs Tradify Pro (£37); VAT submission needs Powered Now Professional (£32); job costing needs ServiceM8 Premium (£119).
5. Cost it at your size in two years
Per-user pricing that's fine solo trebles with two hires. Job credits that fit today may need the next tier up in your busy season, and credits don't roll over. Run both today's numbers and your realistic growth numbers; tools swap uncomfortably, so pick for the business you're building.
6. Check the exit before the entrance
Monthly rolling or contract (Commusoft asks for a 12-month term and targets firms with 6+ staff)? Can you export customers, job history and invoices in a usable format? Your customer list is your business, so confirm you can take it with you before you move in. If the answer isn't in the vendor's docs, that's your first support-team test.
7. Make the trial prove it on real work
Every shortlisted tool has a 14-day trial (ServiceM8 adds a permanent free tier). Don't poke around an empty account: import ten real customers, build five real quote line items, quote a real job, schedule it, invoice it, and 'pay' it. One evening of honest trialling on real data beats every comparison page ever written, again including this one.
Questions people actually ask
How long does switching job management software take?
For a small trade business: plan an evening for honest trialling, then a day spread across a week for real setup: importing customers, building your price list, templating quotes and invoices. The consistent user evidence is that businesses which skip this abandon the software; the setup time is the investment that makes the subscription worth paying.
Should I pick the software my accountant uses?
Pick the software that fits how you win and do work, then make sure it integrates with your accountant's platform (Xero, Sage or QuickBooks). Tradify ships all three integrations from its entry plan; Powered Now publishes Xero from its £32 tier. The accounting sync is a checkbox; the job workflow is the decision.
Do I need job management software if I already use Xero?
They do different jobs. Xero handles your books; job management software handles quotes, scheduling, job tracking and getting paid on-site, then feeds the results into Xero. If your quoting and job admin is already painless, you may not need both. If quotes go out late and invoices lag the work, the job-management layer is the missing piece.
