About

Altair OS is a cloud-based field service management application for HVAC, plumbing, electrical, and other service contractors. It brings lead capture, customer and equipment records, estimates, scheduling, dispatch, technician work, invoicing, payments, time tracking, expenses, and reporting into a connected workflow. Office staff manage jobs and technician assignments from a dispatch workspace, while field teams access job details and record completed work from a phone browser. Estimates can be sent for customer review and approval, then carried into scheduling and billing; completed jobs can become invoices and customers can pay through linked payment workflows. The service tracks customer and equipment histories and includes time and expense records and operational reports. Starter pricing is $39 per month for one user, or $390 annually. A 14-day free trial is available without a credit card; live onboarding is included.

About

XT-ERP is an all-in-one ERP for trade contractors in France: heating and plumbing, HVAC, refrigeration, roofing, electrical and solar companies. Quotes, progress invoices, deposits and retention, job scheduling and dispatch on a map, maintenance contracts with automatic reminders, purchasing and job costing with planned versus actual margins share one database. Every plan includes ten profiles for XT-Talk, the offline field app: daily jobs, customer history, photos, signatures and time entries. Invoices are issued in Factur-X through an approved e-invoicing platform, in line with the French reform. Refrigerant forms (Cerfa 15497), waste tracking (Track Déchets) and F-Gas reports are handled from the job record. Built-in AI: the XT-Académie assistant answers how-to questions inside the software, and the Compagnons Experts estimate renovation grants and spot potential jobs in an area. Developed in Créteil, France, by Adler Technologies since 1998.
