On a passenger-car lot, the sticker is the truck. On a commercial lot it is barely the beginning. A chassis cab rolls in at eighty-some thousand, and by the time a mechanics body, a crane, a liner and a light package are on it, that truck can be worth two hundred thousand and change. Price it off the chassis sticker and you have mispriced it by more than the chassis cost.
The problem is not that dealers do not know this. It is that most inventory systems were built for cars, where a unit is a single line with a single price. A built truck is a chassis plus everything bolted to it, and if the system cannot hold that shape, the upfit ends up living somewhere the price does not see.
The upfit invoice lands in the wrong place
Here is the usual failure. The chassis comes in and gets a record. The body goes to the upfitter. Weeks later the upfit invoice arrives and it goes to accounting, filed against the month, not against the truck. Now the unit on the lot shows an eighty-thousand-dollar cost and the real number is double that. Every report that touches this truck is wrong: the margin looks enormous, the aging cost looks small, and the asking price, if anyone sets it off the record, is far too low.
The fix is structural, not procedural. The upfit cost has to attach to the unit, not to the general ledger, so the truck carries its own built cost wherever it appears.
Chassis and upfit, tracked separately, priced together
The clean model is to record the chassis and the upfit as separate figures on the same unit. The chassis has its factory invoice. Each upfit has its own invoice. The effective price is the two added together, so the number you quote reflects the built truck, not the bare frame.
Keeping them separate matters as much as adding them. You want to know, on any given unit, what the chassis cost and what the build cost, because they age differently, they are financed differently, and when you discount, you need to know which part has room. A single blended number hides all of that. Two numbers that sum give you the total and the breakdown at once.
Scan the invoice, do not retype it
An upfit invoice is a dense document, and retyping it into an inventory record is both slow and a place for errors to enter. The better path is to scan it and let the system read the vendor, the invoice number, the date and the total straight off the page, then confirm what it found in one click. The invoice becomes the source, the cost lands on the truck as its own line, and the built price follows.
A person still approves the number before it counts, and that is the point rather than a limitation. The scan takes out the typing, not the judgement. An upfitter's invoice can carry a deposit, a credit or a line that belongs on a different truck, and none of those should post themselves.
Why the built price has to be right everywhere
A correct built price is not a nicety for the pricing screen. It flows into everything. Your aging report should show the real carrying cost of the unit, which includes the financed upfit, not just the chassis. Your margin report should compare the asking price against the full built cost, or the gross is fiction. Your online listing should advertise the truck that exists, not the chassis that arrived. Get the built price wrong in one place and it is wrong in all of them, because they all read the same record.
The pattern
A commercial truck is a built unit, and its price is a built number: chassis plus upfit, tracked apart and summed. The moment the upfit cost lives on the truck instead of in the ledger, every downstream number gets honest at once, the margin, the aging cost, the asking price and the listing.
ProInventory360 records chassis and upfit pricing separately on the same unit, reads upfit invoices by scan so the cost lands on the truck instead of the ledger, and carries the built price into the unit's own screen and the margin report. The inventory table keeps MSRP and upfit price in their own columns, so you get the total and the breakdown at once. See what it tracks.
