Case Study: Custom Heat achieves scalable growth through real-time scheduling and instant invoicing with Commusoft

Custom Heat Transforms Their Business with Commusoft

Custom Heat, a family-run heating and plumbing business in Rugby with 35+ employees, struggled with a paper-based system and manual weekly invoicing that led to missed jobs and slow payments as demand grew. For the last four years they’ve been using Commusoft to manage their scheduling, communications and billing across 10 office staff and 30 field engineers.

Commusoft implemented a cloud-based diary and mobile app so appointments appear in real time, engineers can invoice on-site with one click, parts requests and office communication are instant, and after‑care emails and SMS reminders are automated. The result: invoicing time cut from a week or more to immediate on completion, no lost jobs or parts, better customer communication and the operational confidence to scale — all delivered by Commusoft.
