How Flödet Plumbing in Malmö Stopped Losing Margin on Every Bathroom Job

For you: you run a plumber (VVS) crew and you are tired of guessing material costs, chasing status calls, and watching invoices sit in a glovebox for weeks.

Flödet Plumbing is a four-person VVS firm in Malmö that lives on bathroom renovations and the kind of 11pm leak that floods a downstairs neighbour. The work was steady and the reputation was good, but the office was quietly leaking money: material costs nobody tracked, quotes that under-priced labour, and invoices that went out three weeks after the last pipe was tightened.

The 11pm call-out problem

When a coupling let go in a Limhamn apartment late on a Tuesday, the customer would call the owner's mobile. He'd scribble the address on whatever was nearest, drive over, fix it, and then — days later — try to reconstruct what parts went in and how many hours it took. Half the time the notes were gone. The job got billed from memory, which always rounds down.

Emergencies were only the loud version of a quieter problem. Every bathroom renovation involved a run to the wholesaler, a cart full of fittings, valves, and a mixer the customer "had to have," and a receipt that ended up crumpled in a van door pocket. By the time the office reconciled it against the quote, the margin had already evaporated. The owner reckoned roughly one job in five came in at or below cost.

"We weren't a bad business. We were a good business losing money in the gaps between the job and the invoice."

From paper to one tap

Flödet switched the whole flow onto FieldApp over a single quiet week in winter, branded in their own colours so customers never saw a third-party tool. The first thing that changed was the front door: a branded online booking page replaced the owner's overloaded mobile. Customers picked "bathroom renovation," "leak / emergency," or "service," and the request dropped straight onto the drag-and-drop schedule — no triage call required.

Quotes were the real turnaround. Instead of two evenings a week at the kitchen table, the owner now builds a bathroom quote in the field in about 20 minutes. He adds labour and materials from a saved price list, and FieldApp applies the Swedish ROT deduction automatically — 30% of the labour cost in 2026 — so the customer sees the after-deduction price without anyone doing arithmetic. The customer signs on their phone with e-signature, and the accepted quote becomes the job. No printing, no "let me get back to you."

Out on site, the crew runs the offline field app on their phones. In a concrete stairwell with no signal it still works: photos of the old installation, voice notes on what the customer changed, and a checklist for the rough-in. Materials get logged as they're fitted, against the job, the moment they come out of the van — which is the single change that stopped the margin leak. For the wet-room work, the egenkontroll (self-inspection protocol) is filled in on the same screen and attached to the job, so the documentation Säker Vatten-style work demands is done before they leave, not invented later.

What changed in 90 days

Within the first quarter the numbers moved in the direction owners actually care about:

• Invoices same-day instead of three weeks. Because materials and hours are already on the job, the office turns a finished job into an invoice in minutes and syncs it to Fortnox. Cash now lands roughly 18 days sooner.
• Quotes from two evenings a week to 20 minutes each. The owner got his Tuesday and Thursday nights back, and quote-to-acceptance went up because customers sign on the spot.
• Zero missed call-outs. Emergencies hit the schedule and the field app, not a sticky note, so nothing falls through.
• Margin recovered on roughly one in five jobs that used to break even, simply because materials stopped going untracked.

The status calls disappeared too. The customer status portal lets the homeowner see when the crew is booked, when work is underway, and when the egenkontroll and final invoice are ready — so the "are you still coming?" calls that used to interrupt every job-site afternoon mostly stopped. The geofenced time clock quietly handles attendance and feeds payroll, which means the owner no longer reconstructs everyone's hours from text messages on the 25th.

The quiet upgrade: an assistant in the office

The piece the owner didn't expect to lean on was the built-in AI assistant. He uses it to draft the customer-facing job description on a quote, to summarise a long voice note into a tidy work log, and to answer "what did we charge for a comparable wet-room last spring?" without digging through folders. It's not magic — it's the admin nobody on a four-person VVS crew has time for, handled in the background.

Flödet didn't add headcount or work longer days. They closed the gaps between the job and the invoice, and the margin that was leaking out of those gaps came back. If you run a VVS firm on bathroom renovations, ROT jobs, and emergency leaks, FieldApp gives you the same flow — branded booking, ROT quotes with e-sign, an offline field app, egenkontroll, time clock, and same-day invoicing — for 590 kr per user per month. Try FieldApp free for 14 days and send your next invoice the day you finish the job.
