Procell RepairLet the system suggest the price
In most shops the price of a screen depends on who is standing at the counter. One tech charges $180, another charges $150 for the same job, and neither of them is wrong — because nobody ever wrote down what it should be.
Set the suggested price per part type
In the catalog, each problem — screen, battery, charging port — can carry a suggested sale price. Set it once, per model if you want, and it stops being a decision anyone has to make again.
When adding stock, you only load cost
That is the point: the person entering twenty parts should not be doing markup math on each line. Cost goes in, the sale price comes out of what you already decided.
It fills in on the repair
At intake, the price appears already suggested. You can change it — a difficult job or a regular customer is a reason — but you are deciding to change a number, not inventing one.
And it protects your cost too
If you leave the part cost empty on a repair, the system uses the catalog cost instead of leaving it at zero. That single default is what keeps your profit reports from lying to you.
