Rental Quote
A proposed price for a rental, shared before the customer commits and recorded in the supplier's billing process.
A rental quote is the number a supplier gives a customer over the phone or in person before anything is confirmed: these dates, these products, this delivery address, this price. It is distinct from an order, which only exists once the customer has actually committed to the rental.
For DME specifically, a quote usually needs to account for a few things at once: the rental length (since price books are rarely flat per day), a delivery or pickup fee if one applies, and, in a lot of small operations, some amount of case-by-case judgment on price, a loyal referral source, a hardship case, a bulk order.
The gap between a quote and a final invoice is where a lot of DME shops lose track of what they agreed to. Record the accepted price in your billing process and check the eventual invoice against it. A TrackDME reservation is an equipment hold, not a priced quote or an invoice, and accepting a quote elsewhere does not create a TrackDME rental automatically.
