Built for Small Teams, Not Enterprise IT Departments
A small UK field service business doesn't need the complexity of an enterprise platform. ONAP SitePro gives small contractors and sole traders the essentials, set up in days and priced for a small team.
Field Service Software Built for Small UK Teams
Most field service platforms are built for businesses with dozens of engineers and a dedicated IT team to set them up. ONAP SitePro is built for small UK contractors and sole traders who need scheduling, invoicing and customer records working on day one, without a lengthy setup process or a per-user price that climbs out of reach as the team grows.
Live Within Days, Not Weeks
Small teams can be scheduling jobs, sending invoices and managing customers within days of signing up, not weeks of configuration.
Pricing That Fits a Small Team
Plans start from £99/month for up to 5 engineers, with no long-term contract and no setup fee, so cost stays predictable as you grow.
One Platform, Not Five Tools
Scheduling, invoicing, customer records and job history live in one system instead of a mix of spreadsheets, paper diaries and separate apps.
No IT Team Required
Built to be set up and run by the business owner or office manager directly, with onboarding support included rather than a dedicated implementation team.
What a Small Field Service Business Actually Needs
Small UK contractors and sole traders don't need the full depth of an enterprise field service platform. ONAP SitePro focuses on the parts of the job that matter most day-to-day: getting jobs scheduled, engineers dispatched, customers recorded and invoices sent, without paying for complexity a small team won't use.
Simple Job Scheduling
Book jobs onto a visual calendar and assign them to an engineer in seconds, without needing to learn a complex system first.
Mobile Job Access
Engineers see job details, customer addresses and notes on their phone, so the office doesn't need to relay information by phone call.
Quotes & Invoicing
Turn a completed job into an invoice without re-entering details, and send quotes customers can approve before work starts.
Customer & Site Records
Keep customer contact details, site history and past jobs in one place instead of scattered across spreadsheets and paper files.
Basic Reporting
See which jobs are outstanding, which are invoiced and how the business is tracking without building your own spreadsheet reports.
Grows With the Team
Move to a higher plan as the team grows past 5 or 20 engineers, without switching platforms or re-entering historical data.
Small Business Field Service Software, by Trade
Small field service teams work differently to large contractors. ONAP SitePro adapts to how a small UK business actually books, dispatches and invoices work, whatever the trade.
For Sole Trader Electricians
Manage call-outs, inspections and invoicing on your own without hiring office admin help. Quotes, job history and customer details stay organised from your phone between jobs.
For Small Plumbing & Heating Teams
Fit emergency call-outs around booked appointments and keep two or three engineers scheduled without a dedicated dispatcher. Everything stays visible from one screen.
For Small HVAC Contractors
Track recurring maintenance visits and one-off repairs without a spreadsheet for each customer. Automatic reminders reduce missed appointments as the client list grows.
For Small Pest Control Businesses
Schedule treatment visits, log job history per property and send invoices immediately after a job, all from a system sized for a small team rather than a national operator.
For Growing Cleaning & Facilities Teams
Start with a handful of engineers and contracts, then add contract management and live tracking as the team and site count grow past what a spreadsheet can handle.
From Signing Up to Running Jobs
Small UK field service businesses don't have time for a multi-week rollout. ONAP SitePro is designed so a small team can be fully operational within days, with support available at each step rather than a long implementation project.
Sign Up & Choose a Plan
Start on the Starter plan at £99/month if you're a small team of up to 5 engineers, with no setup fee and no long-term contract.
Add Engineers & Customers
Bring in your existing customer list and add engineers to the system, importing records rather than starting from a blank slate.
Schedule Your First Jobs
Start booking jobs onto the calendar and dispatching them to engineers' phones, usually within the first few days of setup.
Send Your First Invoices
Convert completed jobs into invoices directly from the job record, connecting scheduling to billing without double entry.
Grow Into a Higher Plan
Move to Growth or Scale as engineer count or feature needs increase, without migrating to a different platform.
