A dealership service invoice is designed to be signed, not read. Phantom quantities, chemicals the manufacturer never asked for, and percentage fees itemized nowhere hide inside a page of part numbers most people scan for ten seconds. This site exists to make that ten seconds enough.

Tap Choose file to use your camera, or drop a file here on desktop. Multi-page invoices: add every page — the fee that gets missed most often is printed on page two.

Preview: the automated reader is in development — running it shows sample output from Case #001, not a reading of your file.

Before you upload: a service invoice usually carries your full name, address, phone number, and VIN. None of that is needed to find padding in the pricing. Cover or crop the customer block first — the part numbers, quantities, and totals are the only part that matters here.

The two checks that catch the most money

These are pure arithmetic against numbers already printed on your invoice, so they run right here in your browser with nothing sent anywhere. On the first invoice this site audited, these two checks alone found $69.33 (Case #001).

1 · Capacity check

A car holds what it holds. Fluid billed past that capacity either never went in, or went in and shouldn't have.

These are common ballparks to get you moving. Your owner's manual has the exact number — use it if you have it.

2 · Invisible fee check

"Shop supplies" and "misc charges" are supposed to cover rags and solvent. If the number is a clean percentage of your bill, it's a formula, not a supply.

Look in the totals box, not the line items. That's the whole trick — it's printed where nobody reads.

The reference

How service invoices pad

Every one of these is a documented, ordinary practice in dealer service departments — none of them require anyone to be a villain, which is exactly why they survive. Search it, or filter by where on the invoice it hides.

A 2025 CR-V Hybrid with 13,232 miles goes in for an oil service. It comes out with six quarts billed into a 4.2-quart engine, three quarts billed into a 1.32-quart differential, a $48.88 aftermarket additive the manufacturer specifies nowhere, an $18.99 injector cleaner nobody asked for, a technician's note certifying the pressure of a spare tire the car does not have — and an open safety recall still open, deferred for lack of time on a two-hour visit that found time for the upsells.

At the counter

What to actually do at the counter

Finding the padding is the easy half. Getting it removed is a tone problem, not an argument problem.

Ask before you pay

Every line is easier to remove before the card is run than after. "Can you walk me through this one?" is a complete sentence and costs nothing.

Quote the spec, not the grievance

"The manual says 4.2 quarts and this is billed for 6" ends differently than "this feels high." Numbers move an invoice. Feelings don't.

Get the correction in writing

Ask for the revised invoice, not a verbal promise or a credit "next time." If a line was wrong, the paper should say so.
