Book an autopsy →- Q01
What margin should a home services business make?
It depends on your trade, your kit deal, your labour and your area. The calculator shows yours; what matters is that marketing comes out of the margin, not the price.
- Q02
What counts as fixed costs?
Everything you pay whether you install or not: vans, wages for office staff, rent, insurance, software.
- Q03
Should marketing be in fixed costs?
We keep it separate so you can see what it does. A retainer that brings no installs is a fixed cost; one that does pays for itself.
- Q04
Is anything I type saved?
No. It is worked out in your browser and goes nowhere.
Is there still a solar place? 6 of 60 left, UK-wide.
