Time Tracking and Attendance on the Job Site

Accurate time tracking and attendance on the job site is the difference between a field-service business that quietly leaks profit and one that bills every billable hour. For electricians, plumbers, carpenters, HVAC and solar crews, the hours logged on site drive your payroll, your invoices and — in Sweden — your ROT documentation, so getting them right matters more than almost anything else in the back office.

Why is job-site time tracking so hard for field teams?

Office staff clock in at one desk. Field technicians start at a different address every morning, often with no signal in a basement or a half-built house. That mobility is exactly why paper timesheets and end-of-week guesswork fall apart.

• Rounded and remembered hours. A tech who fills in a timesheet on Friday is reconstructing the week from memory. Studies of manual timesheets consistently show hours drifting in 15-30 minute increments — almost always in a direction that costs the employer.
• Travel and drive time get lost. Moving between three jobs in a day is real working time, but it rarely lands on a paper sheet correctly.
• Disputes you can't win. When a customer questions an invoice, "trust me, it was six hours" is not evidence. Timestamped records are.
• Slow, error-prone payroll. Re-typing scribbled hours into a spreadsheet introduces mistakes and burns a day of admin every month.

What should a modern time clock actually do?

A job-site time clock should remove judgement calls from the technician and produce clean, auditable data automatically. The features that matter:

• Geofenced clock-in/out. The app knows when a technician arrives at and leaves a job address, so attendance is tied to a real location, not a self-reported number.
• Per-job time, not just per-day. Hours need to attach to the specific work order so you know the true labour cost — and margin — of every job.
• Offline-first capture. A field app that keeps working in a basement or a rural site and syncs when signal returns. If the clock only works with full bars, it doesn't work.
• One-tap simplicity. If clocking in takes more than a couple of seconds, crews stop doing it. The best system is the one technicians actually use every single day.
• Clean export to payroll. Approved hours should flow to a payroll file in minutes, not get re-keyed.

Geofencing without the surveillance vibe

Done well, geofenced attendance is about accuracy, not tracking people's lunch. It captures arrival and departure at the work address and stops there. Be transparent with your crew about what is recorded and why — accurate hours protect them in a dispute as much as they protect you, and that framing keeps adoption high.

How does accurate attendance feed payroll and invoicing?

The real payoff comes when time data stops being a standalone chore and becomes the spine of your operations. When hours are captured against the job, the same numbers can flow straight into your invoice, your payroll run and your job-costing report without anyone copying a figure twice.

That single source of truth changes how a workshop runs. A foreman approves the week's hours on a screen; payroll exports a CSV; the customer invoice shows defensible, timestamped labour. Nothing is reconstructed from memory, and nothing is typed twice.

What this means for Swedish ROT and grön teknik jobs

For Swedish field-service firms, labour hours are also the basis of the ROT deduction. As a general rule, ROT gives the homeowner a tax reduction of 30% of the labour cost, subject to a per-person annual cap, and the deduction applies to labour — not materials — so your time records have to be clean and clearly separated. Grön teknik (for example solar installations) works on a similar deduction-from-the-invoice model but with its own rates and rules. Because these limits and percentages change, always verify the current figures and eligibility directly with Skatteverket before you rely on them. Solid, timestamped attendance data is what makes a ROT claim quick to prepare and easy to defend if it's ever questioned.

Why an all-in-one field system beats a standalone app

A dedicated time-clock app solves one problem and creates a new one: another silo to reconcile with your scheduling, invoicing and field paperwork. When the time clock lives inside the same system as your booking, scheduling, checklists and invoices, the hours are already attached to the right job and the right customer the moment they're recorded.

That's the design idea behind FieldApp — a Cloudflare-native, white-label operating system for field-service businesses. It pairs a geofenced time clock and payroll export with branded online booking, quotes that calculate the ROT deduction and collect an e-signature, drag-and-drop scheduling, an offline field app with checklists, photos and voice notes, self-inspection protocols (egenkontroll), and invoicing that syncs with Stripe and Fortnox. Attendance isn't a bolt-on; it's wired into the same flow as everything else your crew already does on site. Plans start at 590 kr/user/month, so you can put real numbers behind your jobs from day one — try FieldApp free for 14 days and see your first clean payroll export.
