Close the deal
Sold, on proper paper.
Mark it sold and the paperwork follows — branded invoice, deposit receipt, part exchange off the bill. The customer signs on the glass and your terms print with it.
INVOICE · INV-0042 · Signed · Balance due £6,250.00
Built for the trade
Paper, not promises.
StockBook is a new app, so we'll still skip the inflated headline stats. Here's the document a sale actually produces.
One tap
Sold car to signed invoice.
Open the car, tap Sales invoice. Logo, customer, warranty — assembled while you're still holding the keys.
Part exchange
Their old car, off the bill.
The allowance deducts itself on its own line, and the PX car lands in your stock at what you gave for it.
On the glass
Signed with a finger.
Your company signature is saved once. The customer signs at the sale — both land on the paper.
Page two
Your terms, frozen per sale.
Sale terms print with every invoice and never change behind a signed document's back.
