Quote Fees
Quote fees add a clearly labelled fixed charge to an offer. They suit costs that belong to the negotiated transaction but should not be hidden in a product price or shipping rate, such as special packaging, expedited handling, or documentation.
A fee can be selected by an administrator or assigned by a workflow rule. Its label and amount appear in quote totals and are carried into the resulting order, including the related invoice and credit-memo totals.

Tax treatment is configurable per store scope. Before using a fee in production, confirm whether its amount includes tax and test the result for the countries, customer groups, invoices, and refunds used by your store.
For setup fields, tax behaviour, automation, and a launch checklist, see Manage Quote Fees. See also Quote totals and calculation for the order in which fees contribute to the grand total.
