Where Fergus wins
Purpose-built for heating and plumbing trades. Strong quoting, invoicing, and job scheduling. Xero integration is best-in-class.
If that describes your business, Fergus is a strong pick.
Where Fergus falls short for most UK solo trades
Not UK-founded, so some workflows (VAT reverse charge, CIS) require setup. Per-user pricing gets expensive fast. No AI receptionist or missed-call automation.
The biggest gap: Fergus does not include an AI receptionist or automated missed-call SMS out of the box. The average UK solo kitchen fitter loses £129,000/year to unanswered calls. Bathroom fitters lose £75,000. Heating engineers £105,000.
Head-to-head pricing
Migration: how hard is it to switch?
If you are already using Fergus, moving to Unavoidable CRM takes roughly 5-7 working days. Data export from Fergus is straightforward (CSV export of contacts, jobs, invoices). Import into Unavoidable CRM is guided by its onboarding team. No downtime: both systems run in parallel for the first two weeks so nothing slips. Unavoidable CRM is a separate product built and run by Unavoidable Studio Ltd.
Give your team a fortnight to unlearn Fergus’s specific workflow language. The tools do similar things but the terminology differs.
