We solve the real problems of window companies

A complaint a year later – and you have no documentation

The customer calls: “The window leaks, it is your fault!” When was it installed? Who installed it? In what conditions? Did he sign the report? You search the binders… there is nothing. You pay out of your own pocket.

The scenario: A complaint after 11 months. The customer claims the window was installed badly. You have no installation report, no photos, nothing. His word against yours. You replace the window for €815 because you cannot prove the installation was correct.
1 complaint with no documentation = €465 - €1,160

Installation report with full documentation

The fitter completes the report: before and after photos, levels, foam, sills. The customer signs off. Everything is in the system – you will find it in 10 seconds five years from now.

  • Installation photos – the opening before, the foaming, the finish
  • Installation checklist – level, plumb, anchors, foam, silicone
  • Handover report – the customer’s signature = acceptance
  • Job history – survey, installation and service visits, all in one place
100% of jobs documented = no lost complaints

Chaos in the schedule – crews cross paths, customers wait

You have 3 fitting crews and 2 surveyors. Who goes where? Excel, a whiteboard, phone calls… In season it is one thing after another. Customers call: “When are you coming?” and you have no answer.

The scenario: The crew was due at the customer at 9:00. It is 11:00 and they are not there. You call: “We are just finishing the previous job.” The previous one? You thought they finished it yesterday. Angry customer, the whole day wrecked.
Chaos = -20% crew productivity

Real-time crew calendar and map

You see where each crew is, what they are doing and when they will finish. You schedule jobs in advance. The customer gets a text with a confirmation and an ETA.

  • Crew calendar – drag and drop, colour-coded statuses
  • GPS map – live crew locations
  • SMS to the customer – “The crew will be with you at 14:30”
  • Multi-day scheduling – big jobs spread over several days
+30% more installations a month and no more “where is the crew?”

Service and adjustments – “and who was there last time?”

The customer calls after 2 years: “The window is hard to open.” Who fitted it? Which window is it? Were there earlier service visits? You search, you cannot remember. You send an engineer blind – when he could have taken the right parts with him.

The scenario: A window service call. The engineer arrives and it turns out to be a lift-and-slide HST. He does not have the right hinges with him. He drives back to base and out again. 2 hours lost.
Double trips = €47 - €93 per job

The full window or door history in the system

Before setting off the engineer sees which window it is, when it was fitted, what service visits there were and what was replaced. He knows what to take. Fixed first time.

  • Window and door record – type, profile, dimensions, colour, hardware
  • History of every visit – installation, adjustments, replacements
  • Notes and photos – “difficult access”, “demanding customer”
  • Maintenance reminders – servicing every 12 months
-50% double trips and faster diagnosis

“We used to have some measurement slip-up every month. Since we started using Fieldworker, none. The customer-signed reports saved us in two disputed complaints. The system paid for itself in the first quarter.”

Frequently asked questions

Can I create my own survey templates?

Yes. You define the fields, dimensions and checklists for each type of window or door. You can have a separate template for PVC, timber, aluminium, lift-and-slide HST or entrance doors.

Can fitters annotate photos?

Yes. Drawing on photos, arrows, text and measurements. Ideal for documenting installation details.

Does the system work offline on site?

Yes. Surveys, photos and reports all work offline. It syncs automatically once the signal returns.

Can I generate the reports as PDFs?

Yes. A PDF with your logo, the customer’s details, the measurements, photos and signature. Emailed with one click.

How long does the rollout take?

1-2 days. Customer data import, template setup and online training. Crews pick it up in an hour.

Integrations with window quoting software?

A REST API to integrate with any system. We can help you connect to software such as Klaes, Logikal or Excel.
