Arb Pro vs ArbM8

Arb Pro is a customer relationship management system for tree contractors and arborists, covering quotations, invoices, tools, risk assessments, and related business activity. Its web-based Arb Office requires no software installation and includes a shared calendar, dashboard, client management, messaging, tree mapping, marketing, quotes, invoices, and customizable risk assessments. Arb Quotes gathers customer, tree, cost, photo, map, tool, and risk information onsite and syncs it to Arb Office. That app currently supports iOS; its Android version is in development and due for release in 2026. Arb Work runs on iOS and Android for booked work, assessments, customer signatures, and invoicing from the site.

The mobile app can collect data offline. Arb Pro connects with cloud versions of Sage, QuickBooks, Xero, and KashFlow, and sends appointment events one way to Google Calendar. Client lists can be exported as CSV. Plans are monthly and do not tie users into a contract. Tree Contractor Lite costs £60 a month plus VAT and includes one desktop app, one quoting app, and one work service app.

ArbM8 is tree management software built on the ServiceM8 platform, with workflows for arboricultural businesses handling tree care and consultancy work. Its listed capabilities include mobile quotes, automation, a job diary, GPS tracking, on-site invoicing, risk assessments, method statements, incident management, completion certificates, TPO/CA management, accountancy integration, and asset management. The Advanced package lists forms for risk assessments, method statements, additional or emergency work orders, incident reports, job completion, pesticide records, worksite audits, and rigging plans. It includes QBO integration if applicable. Setup packages cover account creation and staff or team setup, while templates, forms, and configuration vary by package. The package prices are one-time charges: Set-Up Only is £720.00, Intermediate is £1116.00, and Advanced is £1440.00. These amounts do not include the monthly ServiceM8 subscription.
