Everything you need
NoProb replaces the messy stack of paper, spreadsheets, and apps every engineer pieces together. Built for one-handed use in the van.
Snap a photo of any model plate. Brand, model number, and appliance type identified in 4 seconds. No more squinting at scratched labels.
Your week at a glance. Drag jobs, reschedule with two taps, see what's billable, what's overdue, and what's tomorrow.
Send a quote from the van in 60 seconds. Auto-mark invoices overdue. Track who paid, who didn't, and chase the rest automatically.
The fault code library every engineer wishes they had. Search by brand, model, or symptom. Get the fix in seconds, not hours of forum scrolling.
Every customer, every appliance, every history note in one place. The next 5 jobs are already in your phone — you just haven't asked yet.
Track every expense against every job. See real profit per job, per week, per year. Finally know what you actually take home after parts and fuel.
How it works
Plumber, electrician, HVAC, appliance repair, or any other trade. The app adapts to your specific work — features, layout, and fault codes all tailored to what you actually do.
Customer, appliance, time. Done in 30 seconds. Auto-saved to your diary and ready to invoice.
Add jobs, send quotes, take photos, fire invoices. From the van. With one hand.
From a real engineer
Thirty years in this trade and I never thought I'd see the back of Sunday paperwork. After a month using NoProb, my wife noticed I was getting to bed earlier. The lad who built it grew up watching me chase invoices — that's why it actually works.
Questions every engineer asks
Yes. NoProb is offline-first. You can log a job, take photos, and write notes in a Stoneybatter utility room with no bars. Everything syncs automatically the moment you have signal again.
Yes. Add your bookkeeper or partner as a user from your settings. They can log in on a laptop, pull a clean CSV for the accountant, and export every invoice and expense without touching your phone.
Yes — every invoice, customer, and job exports to CSV in one click, any time. No hostage data. We don't believe in trapping anyone.
Yes. Add your VAT number in settings and every invoice automatically includes it, plus the right VAT rate (13.5% services, 23% goods, or any other rate you set). Built for the Irish and UK trade.
Yes — it's the feature we tested most. It uses Claude AI which handles partial labels, oil stains, and bad lighting better than Google Lens. If it can't read it, it falls back to manual entry instantly.
Yes. Every job and invoice generates a clean PDF you can print or email. Some customers will always want paper — NoProb doesn't fight that, it serves it.
Founder's promise
I built this for my dad. I'm not in this to take your money.

Our story
NoProb wasn't built by ex-Salesforce people in a glass office. It was built for one appliance engineer with thirty years on the road.
He was drowning in paper invoices, missed calls, and Sundays lost to admin. So we built him an app. He's been testing it on real jobs for months.
Now we're sharing it with every engineer who's tired of running their business from the kitchen table.
Launching soon. Be first in line.
