Opsler is a field service management platform for scheduling and dispatch, customer management, invoicing and technician work. Its documented 42 features span sales, scheduling, field work, customers, billing, inventory and reporting. The Field Agent app lets technicians access assigned jobs, update status, complete checklists, capture photos and signatures, create invoices and record payments offline, then sync later. Customers can use a token link without logging in to track technician ETA, approve estimates with OTP verification and a signature, view job and invoice history, pay, message technicians and check warranties. Accounting exports support manual import to QuickBooks Online, Xero or generic CSV; the platform does not provide live two-way accounting sync. Opsler states it charges a 0% platform fee for payments, while businesses use their own processor and rates. The free Budding plan allows two seats and 50 jobs per month. Pro costs $25 a month, has no seat minimum and includes all 42 features. Devices install from a browser rather than an app store.
