Pays for itself in a week.

Most tradies lose 15 minutes a day to paperwork, lookup, and re-typing job notes. Knockoff Pro pulls that time back.

  • Saves invoice time — timer rolls straight into a GST invoice. No re-typing.
  • Stops lost hours — GPS auto clock-on means every minute on site is billed.
  • All 25 calculators — concrete, roof, stairs, voltage drop, GST, the lot.
  • NZ Building Code & WorkSafe — full PDFs offline. No signal, no problem.
  • Weather risk planning — 7-day site forecast, auto-reschedule the risky days.
  • Xero invoice export — one tap, straight to your accountant.

Pick a plan that fits your trade.

From the worksite, not the boardroom.

"Used to spend Sundays writing invoices. Now it's two taps from the ute. Got paid five days faster the first month."

"The earnings ticker is dangerously satisfying. Watching the cents roll while you're cutting timber — pure dopamine. Brilliant."

"NZS 3604 in the back pocket without internet means I'm not the bloke calling the office for a span table any more. The hip-roof calc saved me an hour yesterday."

The bits people ask before they install.

Does it work without internet on site?
Yes — the timer, all 25 calculators, NZ Building Code PDFs, and your saved timesheet entries all work offline. Invoices sync to Xero next time you're in range. The PWA caches everything on first install via a service worker.
What's actually in the 25 calculators?
Concrete: volume (multi-shape), bags, rebar layout. Masonry: block wall, brick wall. Roof: pitch, rafter, gable, hip, skillion. Framing: wall, deck. Stairs: full stairs, rise/run/pitch, baluster spacing. Surfaces: tile, paint. Math: circle, conversions, timber off-cuts. Trade: voltage drop, pipe flow, fastener gauge. Business: GST add/strip, quick-quote.
Which NZ documents are bundled?
Real PDFs: NZS 3604 (1999), SG8 / SG10 span tables (2023), WorkSafe — Working at Height, EWRB Certificate of Compliance / ESC template, LBP Skills Maintenance Record. Plus interactive HTML references for NZ wind / seismic / snow zones, fixing schedules, materials lookup, and weather work matrix. More B-clauses being added monthly.
How does the GST invoicing work?
Knockoff auto-calcs 15% NZ GST on labour + materials + travel. Toggle GST registration off if you're below the IRD threshold. Invoices generate as PDF and as Xero / MYOB-friendly CSV.
What happens to my data if I cancel?
Timesheet history and invoices stay readable on the free plan. Pro features (Xero sync, calculators 6–25, weather alerts, NZ PDFs) lock until you re-subscribe. Export everything to CSV any time.
Is there an iPhone and Android app?
Today, install the web app via the Install button — it adds an icon to your home screen and runs full-screen, no app-store wait. Native iOS + Android with deeper hardware integration ship Q3 2026.
Can my crew use one Knockoff account?
Yes — the Crew plan supports up to 8 crew timesheets under one business. Each crew member gets their own login, timer, and earnings, but invoicing rolls up to the head builder.
