Know what moved before you respond.
A lower payment can come from a longer term, more cash down, a different rate, or products being moved around. PencilProof shows the inputs behind the estimate.
WHO IT HELPS
Use the written quote as a clearer starting point.
Whether you are buying a car or helping a customer buy one, PencilProof turns the written quote into a specific conversation instead of another round of guesswork.
FOR SHOPPERS
Ask for the deal you actually want to review.
Instead of waiting while numbers move back and forth, start with the quote in front of you. Compare the payment without optional products, review trade equity, see what changed in a revision, and ask for an itemized buyer's order.
PencilProof does not negotiate, approve discounts, or replace the dealer's official worksheet. It helps you understand the request you want the dealership to price.
Walk into finance prepared.
Use the audit's prioritized questions and copy-ready request to ask for exact figures instead of trying to remember what changed.
BUILT FOR WRITTEN CLARITY
Designed around the numbers buyers actually receive.
PencilProof focuses on the written quote: price, payment, APR, term, fees, products, trade figures, and amount financed.
Instead of asking buyers to negotiate from memory, it organizes the figures into a clearer starting point for questions and comparison.
