Should duty be itemized separately on invoices when selling duty-paid products, and what are the accounting implications?

It is not standard practice to split out duty as a separate line item on invoices to duty-paid customers. Members advise against this for customer-facing invoices because:

- **Splitting duty on invoices creates confusion** — customers compare prices against agreements, and breaking out duty separately can muddy that comparison and create friction. - **ABV changes become visible problems** — if you change the ABV of a product but keep the invoice price flat (to manage the duty impact), splitting duty out will flag an apparent price increase to customers outside their agreed annual increase window, causing pushback.

However, members strongly recommend splitting duty out **in your internal accounting system**:

- **Track duty separately in your accounts** — this gives you a true view of net sales figures and actual margins. Duty changes (particularly rate rises) can otherwise distort your margin reporting and hide the real performance of your business.

The separation is an internal accounting discipline, not a customer-facing practice.
