Commusoft vs Tradify Pricing UK
This is the biggest practical difference. Tradify publishes its UK prices; Commusoft does not.
| Plan | Price | Notes |
|---|---|---|
| Tradify Lite | £34 per user/month | Jobs, quotes, invoices, card payments, Xero/Sage/QuickBooks sync. No certificates. |
| Tradify Pro | £37 per user/month | Adds gas and electrical certificates, service reminders, recurring jobs, deposits, automatic chasing, timesheets |
| Tradify Plus | £44 per user/month | Adds AI SmartTools |
| Commusoft | Quote only | No public price list. Book a demo for a quote. Third-party listings such as Capterra show a starting point of around £59 per user a month, and some report a 12-month minimum term, so confirm both with Commusoft. |
What that means: a sole trader gas engineer can be up and running on Tradify Pro for £37 a month, cancel any time, with no sales call. Commusoft is a bigger commitment, both in price and setup, which makes sense for a firm with several engineers and an office team, but is usually overkill for a one or two person business.
Gas Certificates and Service Work
Both handle the core gas paperwork. Tradify’s UK site lists the Landlord/Homeowner Gas Safety Record, the Service and Maintenance Record and the Gas Warning Notice on its Pro plan, created, signed and sent from the app, with automatic service reminders and recurring jobs for annual services. Commusoft’s Digital Forms include landlord and homeowner gas safety records (CP12s) and other industry forms completed on the mobile app.
Where Commusoft goes further is the service contract side. Its service plans feature schedules annual services, sends reminders, lets customers book their next appointment online and raises recurring invoices automatically, and its asset records keep the make, model and service history of every appliance. If most of your income comes from service plans and landlord portfolios, that depth is the reason to pay more.
What We Found When We Tested Tradify
Hands-on findings
- Quote to job in two clicks. Accepting a quote created the job with the customer, address and description already filled in.
- Certificates are full forms, not token ones. The certificate menu holds gas, oil, electrical, fire safety and solar forms, pre-filled from the job. The electrical EIC we completed was a full BS 7671 form.
- Quoting keeps your margins private. Customers see quantity, price and total, never your cost or markup.
- Deposits can be a penny out. A 30% deposit plus balance came to £622.52 against a £622.50 quote because of VAT rounding, so check the final invoice.
We ran a job through Tradify’s free trial as a test UK contractor. We have not tested Commusoft hands-on, so its details here come from Commusoft’s own UK website and help centre.
