The free margin check
Two questions first
They set the frame for every check that follows. Nothing here identifies the practice — no name, no address, no patient data.
Check 1 · Structure
Real overhead percentage
Everyone manages production. Fewer owners can say what share of collections the practice spends to run itself.
Check 2 · Vendors
Effective merchant rate
Card fees are the one vendor rate almost nobody negotiates — because almost nobody computes it.
Check 3 · Vendors
Lab fee variance
Same crown, three invoices, three prices. The spread tells you whether your lab spend is managed — or assumed.
Check 4 · Vendors
Supply cost drift
Supplies creep. The only way to see it is as a share of collections — now, and against two years ago.
Check 5 · Recurring spend
Software count
Subscriptions accumulate quietly. Count them once — the annual total usually surprises.
Check 6 · Recurring spend
Unexplained recurring charges
Scroll last month's statement. Anything you can't immediately name belongs in this box.
Check 7 · Collections
Production-to-collections gap
What you produce and what you collect are two different numbers. The gap between them is where margin hides.
Check 8 · Collections
Aged receivables
Money owed past 90 days rarely comes back on its own. Weighed against one month of production, it has a size.
Check 9 · Structure
Staff cost ratio
The biggest cost block in the practice — judged against production, never against headcount.
Check 10 · Structure
Equipment and financing
Leases and loans outlive the equipment they bought. List them once — the auto-renewals are the finding.
The ten checks
That's all of it.
The Marginr engine assembles your dashboard — every band, flag and dollar traceable to a number you typed.
Flagged for the manual read
The dashboard treats every flagged check as a finding — and shows what each one hides.
