When every labor line shows the full charge and no cost, the month looks like the shop kept every dollar of labor. The usual story is duller. No technician was assigned on the ticket, or the technician's cost never crossed from the wage file into the job. The margin is a picture of a hole.
We do not fill the hole with an average. An average from a different week becomes a fiction that then supports a return. The hole stays visible until the ticket names a technician or the wage file explains why nobody was on that job. A one-person shop can still have the hole, if the owner's own time was never given a rule.
A technician is either on payroll or not.
Someone turning wrenches is not automatically an employee, and a nickname on a ticket is not paperwork. If the person is on payroll, the cost belongs in the wage file the provider already runs, then on the job. If the person is a contractor, the paperwork is the contractor kind, and the list those contractors belong on is usually due by the last day of January.
We ask which paperwork applies. We do not guess, and we do not print a person's numbers on this site. Put a contractor on the wage file, or an employee on the contractor list, and the year can open with a letter you did not want. Wage setup happens beside the provider the bay already picked. That provider still cuts the checks.
The shape is the whole month, not one job.
One ticket with a strange margin is an anecdote. A month of them is a shape. Parts heavy and labor empty means the shelf moved and the people did not get attached. Labor heavy and parts empty can mean the parts total never arrived, or the work was diagnosis with no iron. Outside work with no pass-through means the markup and the vendor bill were collapsed.
Seeing the shape is the point of splitting the lines. Once parts, labor, and the work sent out are apart, a week that felt busy can show a quiet margin, and a week that felt slow can show a clean one. The feeling was never the report. Dollars from a real file stay off this page. The pattern is the thing that travels.
A rule you can keep beats a perfect first count.
The first month does not need every clamp counted. It needs a rule. Parts leave the asset when the job closes. Labor gets a technician or it stays obviously empty. Outside work shows the markup and the pass-through. Supplies on the ticket stay income, and the carton stays a cost. The bank is matched, not merely accepted.
Estimated payments, where they exist, sit in April, June, September, and the following January, and they are not labor. A temporary account empties or it stays on a list. A filed month is named before a second send. Those rules are national. A shop on either coast can keep them without borrowing another shop's numbers.
Name the line with no technician.
Say which labor line shows a margin that looks too clean.
You will be talking to the Steven Palmieri practice.
