# Start a POS Working Period

### How to Start a POS Working Period in Muhasib ERP

### Overview

This guide will help you start the working period required for needed POS operations.

Muhasib creates a work-period record and marks it active. A concurrent attempt is rejected when another user has already started one.

### Who can do this

You need access to Access to Working Period and the required POS/register operation permissions.

### Before you start

Confirm the active fiscal year, company, location, terminal, business date, and that another user has not already started the period.

Back Office → Sales &amp; Customers → Working Period.

### Start a POS Working Period

#### Step 1: Open Working Period

#### Step 2: Review the current status and timestamp

#### Step 3: If no period is active, choose Start Period

#### Step 4: Wait for the successful-start message

#### Step 5: Open the required POS register through its supported workflow

### Check your work

Reopen Working Period and confirm Active status/start time. Confirm authorized POS entry can proceed.

- If already started, refresh rather than creating another period.
- If the fiscal year is missing, configure it before transactions.
