Why MARJYN
Busy doesn't always mean profitable.
A full diary and plenty of work can look like a successful business.
But do you know which jobs are actually making you money?
The biggest job isn't always the best job. Doing more yourself doesn't always leave you better off. And subcontracting work doesn't necessarily mean giving away your profit.
MARJYN helps you see the difference.See where your time pays best
Compare what you make with how much of your own time each job takes.
Price the next job better
Use what actually happened on previous work to make a better decision next time.

Straight answers
A few things you might be wondering.

No. Add reliable previous jobs for a faster start, or begin with your next job. MARJYN becomes more useful as genuine completed work accumulates.
Do I need to understand accounting?
No. MARJYN uses plain commercial language to show what work earned, what it took and what changed.
What if I subcontract most of my work?
MARJYN can separate subcontractor costs from your own time, helping you understand both job profit and how the work used you.
