Short answer: Fergus is job management software built for plumbing, electrical and building firms, with strong job costing, timesheets, supplier integrations and purchase orders. Its UK plans list from £39 a month for Essentials and £45 for Professional, and at the time of checking it was running a 90% off offer until December. Unavoidable CRM is priced per business from £29 a month and focuses on winning and keeping the work: an AI receptionist, missed-call text-back, a sales pipeline and automatic follow-ups, alongside quotes, jobs, certificates and invoices. If you run a busy team and the hard part is costing and controlling jobs, Fergus is a serious option. If the hard part is answering the phone and following up quotes, Unavoidable CRM is built for that.
