Operating Expenses are the bills that are not product or labor: rent, utilities, insurance, marketing, professional fees, software, and the rest. Logging them is what lets your Month-End income statement show a real operating income instead of stopping at prime cost. Wages and salaries do not go here; they live in Labor Control.

1. Log a bill

Open Books → Operating Expenses. Add each bill by category with its amount and date. The income statement and your break-even both read these, so the more complete the month, the more honest your operating income.

2. Set the recurring ones once

Check Recurring on a bill that hits every month and Bar Cop logs it for you each month. Recurring bills run until you hit Stop, so fill in Ends after (months) only for a bill that stops after a fixed number of payments, like a financed purchase. For a bill that moves around month to month, leave it Variable and use Repeat to copy last month forward and set the new amount.

3. Import a batch

Switch the form to Import File and drop a CSV or Excel export to load a stack of bills at once, then map the columns.

Do not enter repairs and maintenance or third-party platform fees here; those are tracked in Shift Control and the weekly P&L, so Books does not count them twice.
