About
Job Math helps contractors stop guessing and start knowing.
When you’re running multiple jobs at once, it’s easy to feel profitable - but hard to know where the money actually came from. Job Math is built to answer one simple question:
“Am I making money on this job… or not?”
* Track Real Profit Per Job
See exactly how much you’re making (or losing) on every job.
Track quotes, expenses, labour, and payments in one place - so you know:
- Which jobs are profitable
- Which ones are dragging you down
- When it’s time to stop, renegotiate, or move on
- No more end-of-month surprises.
* Create & Send Invoices Instantly
- Create clean, modern invoices in seconds.
- Send invoices via email or WhatsApp
- Look professional without extra effort
- Get paid faster with clear job-based billing
* Track Expenses (and Bill Them Back)
Expenses add up quietly- until they eat your profit.
With Job Math, you can:
- Track expenses per job
- Add markup if you bill expenses to clients
- Re-invoice expenses later (with or without markup)
- Nothing slips through the cracks.
Built for Real Jobs, Not Spreadsheets
Job Math is designed for how contractors actually work:
Multiple jobs running at once
Delays, partial payments, and lingering jobs
Profit that looks good overall - but feels unclear per job
Stop guessing.
Do the math.
Know your numbers with Job Math.
