Quotes
Provide pricing estimates to customers before starting a subscription or invoice.
You can use quotes to combine recurring and one-off line items so you can provide your customers with a price estimate, including any discounts or taxes. You can convert the quote into a recurring subscription or a one-time invoice after the customer accepts the quote.

How it works
