The Onsite Pro Dashboard


Open Onsite Pro and you land on your dashboard - a live overview of your business with every feature one click away.

Recent quotes, jobs and invoices are on screen, along with read-receipts - every time a customer opens a quote, job sheet or invoice, you’ll know how many times and when.

The top of the dashboard tracks the four numbers that matter - timesheets logged, hours worked, total quotes issued and total invoiced - refreshed monthly.

The Onsite Pro service business dashboard

Built for service businesses since 2012

We launched in 2012 as iManage - the first app that let field engineers complete digital job sheets from a tablet, with the office seeing every signature the moment it landed. The category has caught up, but Onsite Pro is still the simplest way to run a service business from quote to paid invoice.

There's more to it than the app - here's the rest:

Quote and Invoice


Quotes, jobs, orders, invoices, purchase orders and credit notes - all in one place. Onsite Pro logs every time a customer opens a document, so the “I never got the invoice” excuse stops working.

Manage Engineers


Set up new field-staff devices remotely - they don’t need to come into the office. Push jobs to individual engineers or whole teams (first fix, second fix, plumbing, IT support - whatever you call yours), and see live progress and location on a map.

Mobile Timesheet App


Send a job to one engineer or a whole team. Each job carries the tasks, time tracking, notes, photos and parts used - then hand the device to the customer to sign off.

Signature Capture


When the job’s done, the customer signs on screen. Every sign-off is geo-stamped with time and location, so there’s no question who signed, where, or when.

Notes and Pictures


Snap a photo of the finished job and mark it up by hand on the image. Spotted something for next time? Drop a private or shared site note that follows the property.

Include Parts Used


Built-in stock management. Engineers add parts and consumables to a job as they use them on site - so nothing gets fitted and forgotten on the invoice.

Activity Feed


A live feed of every quote opened, job signed and invoice paid. If a job lands, stalls or completes, you see it the moment it happens.

Improve Cashflow


Faster sign-offs, tracked documents and instant invoicing add up to one thing: customers pay sooner.

What our customers say

Working in the AC industry, our engineers all use iPads and now call out forms, notes and follow ups all come direct to the office without the engineers having to come to the office once a week. A great benefit to us in both time and efficiency.

Since we signed up to Onsite Pro we have seen massive improvements in all aspects of our company.

For us Onsite Pro has delivered a huge return on investment. The monthly cost was easily recouped from the first month we began using it.

Each customer gets a dedicated database on UK servers. HTTPS throughout. Daily backups. You own your data and can export it any time.

No surprise charges - we never asked for a card. If you want to carry on, we set up billing then. If not, do nothing and your account closes. We keep your data accessible for 30 days afterwards in case you change your mind.
