Margin + billing leakage
Every finding rolls up its own revenue vs cost.
See which work actually makes money - and which is quietly costing you. What looked like your best customer might be your worst. The report tells you which specific work made it so.
The problem
- Work performed and never billed - the estimator forgot the change order, the tech forgot the extra hour.
- Same line billed twice on progressive invoices because nobody remembered what was on invoice #1.
- You know some customers hurt more than they help but you cannot prove which ones.
- Warranty and rework costs disappear into overhead. Bad tasks look profitable on paper.
What CoreOP does
- Progressive invoicing with a double-billing guard - every draft checks against every prior invoice on the visit.
- Margin per finding - labor + parts + disposition + warranty against revenue, rolled up per task, per tech, per customer.
- Margin intelligence view: by customer, by aircraft type, by service - which work actually makes money.
- Cost of poor quality: rework and warranty rate by task type, with real dollars attached.
- QuickBooks Online sync - GL stays in step, so the numbers you see match the numbers you reconcile.
Real UI
Double-billing guard.
Draft an invoice; the system tells you when a line has already been billed. No second-guessing which was on inv-0042.
