Know the real margin
A selling price can look healthy while the job loses money once waste, parking, a subcontractor and overhead are included. PlumbMargin shows gross profit, margin and markup from the costs you enter.
Stop forgetting job costs
Materials, labour, call-out, waste disposal, hire, permits and subcontractors sit on the same quote. Overhead is a percentage you choose, not a hidden add-on.
Separate internal cost from customer price
The customer PDF shows scope and selling prices. It does not show your internal labour cost, material cost, overhead or margin.
Quote from your phone
The quote flow is a short sequence: customer, materials, labour, other costs, margin, then the customer quote. It works offline after the app has loaded once.
