Know Your Profit.
Before the Job Eats It.
Track quotes, expenses, labour, and invoices in one place — so you always know where you’re making money and where to stop.
Built for contractors, freelancers, and small service businesses
No accounting degree required.
Stop Guessing.
Start Knowing.
Most job apps help you send invoices.
Very few tell you if the job was actually worth it.
With Job Math, you don’t just track money — you understand it:
- ? Are you under-quoting?
- ? Are expenses killing your margin?
- ? Should you keep taking this type of job?
