How do I log a business expense?

Expenses live on the merchant ledger. Tax on an expense is stored separately from the net amount.

1. In Portal or the App, open Commerce, then Expenses.
2. Pick or create an expense category (Rent, Utilities, Packaging).
3. Enter the date, payee, amount, tax amount, and payment method.
4. Add a reference or note, attach a receipt image if you have one, and save.
5. The amount appears on the next P&L export. Sales PDFs stay order-only; P&L subtracts these costs.
