How Kulören Painting in Lund stopped losing quotes in email — and started closing them in 20 minutes with FieldApp

20 June 2026 · 4 min · PaintingROTCase studyField service

For you: you run a painter crew and you're still estimating from memory, chasing quotes in your inbox, and guessing how long each job actually took.

Kulören Painting is a five-painter firm in Lund that takes on everything from a single hallway to a full villa façade. For years their biggest leak wasn't paint — it was the quote that got typed up at 10pm, emailed once, and then vanished into a customer's inbox forever.

The "estimate from memory" problem

Lasse, who started Kulören in 2014, ran the business the way most painters do: with a good eye and a great memory. A homeowner in Värpinge would describe two bedrooms and a stairwell over the phone, Lasse would picture the job, and a few evenings later he'd send a price. It worked, mostly. But "mostly" hid a lot of slow bleeding.

Quotes took two full evenings a week to write, and Lasse could never quite remember whether he'd already applied the ROT deduction or quoted the gross labour. Customers would call back three weeks later asking "did you ever send that?" — and half the time it was sitting unread, or buried under a reply chain. Worst of all, when a finished job went sideways ("this wall looks patchy"), there was no before photo to point to. It was the painter's word against the customer's memory.

Time was the other black hole. Three painters could spend a week on a façade and Lasse genuinely couldn't tell you if the job made money. He priced the next one off a feeling.

"I wasn't running a business, I was running my memory. Every quote, every hour, every promise lived in my head or my inbox. One sick week and the whole thing would have stopped." — Lasse, owner, Kulören Painting

From inbox chaos to one branded flow

Kulören switched on FieldApp during a slow February and started with the front door of the business: a branded online booking page. Now a homeowner in Lund books a site visit themselves, picks a slot, and lands straight in the calendar — no phone tag.

The quote itself was the real unlock. With FieldApp's ROT quotes, Lasse builds a painting estimate from line items, and the 30% Swedish ROT deduction on the labour portion is calculated automatically and shown clearly to the customer. The homeowner signs with e-signature from their phone — no printing, no scanning, no "I'll get back to you." A quote that used to eat two evenings now goes out in about 20 minutes, and it's accepted before Lasse has packed up the ladders.

On site, the crew moved from paper to the offline field app. Because it's a PWA that works in a stairwell with no signal, painters open the job, run a quick checklist, and snap before/after photos of every room and façade. Voice notes capture the "customer wants the trim in NCS S 0500-N" detail that used to get lost. When a wall gets questioned later, the proof is timestamped and attached to the job.

Tracking the hours — and getting paid for them

The geofenced time clock ended the guessing. Painters clock in when they reach the site and out when they leave, so every façade now carries a real labour figure. For the first time Lasse can see that the Värpinge villa took 38 hours, not "about a week," and price the next one off data instead of optimism. The same clock feeds straight into payroll, so Friday admin shrank from an evening to a few minutes.

For larger ROT jobs, the crew fills in a quick self-inspection protocol (egenkontroll) in the app — surface prep, primer, coats, drying — which doubles as a quality record and a sales tool for the next customer.

Then the money. Because hours and signed quotes are already in the system, invoicing is one tap and syncs to Fortnox, with the ROT portion handled correctly for Skatteverket. Invoices that used to go out three weeks after the last brushstroke now go out same-day.

What changed in 90 days

Within a quarter, the numbers told the story Lasse never used to have:

Customers feel it too. The status portal lets a homeowner see "booked → scheduled → in progress → invoiced" without calling, and the built-in AI assistant drafts the polite "we'll be there Tuesday at 8" messages and answers Lasse's "how many ROT jobs did we run last month?" questions in seconds.

If you run a painting crew and your business still lives in your memory and your inbox, FieldApp pulls it into one branded system — booking, ROT quotes, scheduling, the field app, time tracking and invoicing — without the enterprise bloat. It's 590 kr per user per month with a 14-day free trial, so you can quote your next job inside it before you pay a krona. Try FieldApp free.

FAQ

How does FieldApp handle the ROT deduction on painting quotes?

FieldApp calculates the Swedish ROT deduction automatically on the labour portion of a quote — currently 30% of labour cost as of 2026 — and shows the customer their net price before they e-sign. When you invoice, the ROT amount syncs to Fortnox and is reported to Skatteverket. Always confirm current ROT rates and per-person caps with Skatteverket, as they change.

Can painters use FieldApp on site without mobile signal?

Yes. The field app is an offline-first PWA, so painters can open the job, run checklists, take before/after photos and record voice notes inside a stairwell or basement with no signal. Everything syncs automatically once the phone is back online.

How do I track how many hours each painting job actually takes?

FieldApp's geofenced time clock lets crew clock in and out at the site, so every job carries a real labour figure instead of an estimate. Those hours feed both your job costing and payroll, so you can price future façade and interior jobs from data.

Does FieldApp work for a small painter crew or only big companies?

It's built for small field-service teams. A five-painter firm uses the same booking page, ROT quotes, scheduling, offline field app and Fortnox invoicing as a larger one, at 590 kr per user per month with a 14-day free trial — no long contract to start.
