All-in-one job management platform for mobile and field service businesses.
Updated August 2026 · By the ERP Research Editorial Team · Independent and vendor-neutral.
SageQuickBooksBigChange is a UK-based field service management platform that combines CRM, job scheduling, mobile workforce management, vehicle tracking and invoicing in a single system, aimed at trades and mobile service businesses such as plumbing, heating, HVAC, electrical, fire and security, facilities management, and equipment rental. The platform is delivered as an office web app paired with a mobile app for field engineers, replacing paper-based job sheets with digital worksheets, forms, proof-of-service capture, and customer portals.
BigChange's back-office finance capabilities include quoting, invoicing, and cash-flow tracking, with two-way integrations to accounting systems (notably Xero, and also Sage) so that completed job data -- time, travel, labour and parts -- and invoices/payments can flow between BigChange and the accounting ledger without duplicate data entry. The company states integrations can be set up either via its web services library for self-service (DIY) integration or through its Professional Services team for bespoke connections, and it also offers a REST API for custom system integration.
Founded in Leeds, UK, BigChange has grown into one of the UK's established field service software vendors, reporting over 2,200 business customers, and in October 2024 was acquired by Simpro Group, joining sister brands AroFlo, ClockShark and Simpro to form a larger global field-service software group. BigChange has also introduced an AI layer branded "Lightning," adding natural-language query, automated technician briefings, and automated job documentation on top of the core job-management platform.
