Applying a quote

Applying a quote updates the account's subscriptions with the quote's changes, may generate an invoice, and cannot be reversed.

Applying a quote means that the account’s subscriptions will be updated with all the changes contained in the quote.

Until a quote is applied, it’s still just a shopping cart with some items in it. Applying it will make all the contained changes take effect on the account and this operation cannot be reversed. When a quote is applied, an invoice may also be generated and the account balanced is updated accordingly.
