P&L by Service Line for Growing Clinics

A clinic that only reports one blended P&L often celebrates growth while one chair or branch quietly loses money. Service-line views start by naming the revenue units you actually manage—chair hours, procedure families, or locations—then assigning direct costs before shared rent and central staff.

Consumables deserve their own line when they move with volume. Many Thai clinic groups book supplies into a single expense bucket; that hides why a high-revenue specialty still compresses margin after festival weeks of heavy material use.

Shared overhead should be allocated with a rule your partners accept, not a rule that flatters one branch. Headcount, square meters, or chair-hours all work if the rule is written beside the view and revisited quarterly.

When we commission reporting views for clinics, we leave a one-page refresh checklist so the bookkeeper can rebuild the same layout after each close without redesigning the story.
