# Cash Register Management

The **Cash Registers** module allows you to record all money flow in your business: shift openings, income/expense movements, and daily closings.

A good cash register configuration helps you:

- Have traceability of who handled money in each shift.
- Quickly detect cash discrepancies.
- Generate clear reports by day, user, and payment method.

## Key concepts

- **Cash Register**: Represents a physical or virtual cash register where collections and cash movements are recorded. Each box can have an optional **payment surcharge percentage** (e.g. for card payments); this percentage is shown in the boxes table and in the configuration labels, and is applied when collecting via that box in the POS.
- **Shift**: Period of time in which a user (or group) operates a cash register.
- **Cash movements**: Income or expenses of money that don't come directly from sales (for example, petty cash replenishment, withdrawals, minor expenses).

## Typical usage flow

1. Open a cash register shift with an initial amount.
2. Record sales from POS (automatically credited to the open cash register).
3. Record manual movements (income/expenses).
4. Close the shift and compare expected balance vs. actual balance.
5. Review daily and per-user reports.
