# Configure and Test FBR POS Integration

### How to Configure and Test FBR POS Integration in Muhasib ERP

### Overview

This guide will help you configure FBR POS identifiers and successfully validate a representative sandbox sale.

Muhasib stores the local sale and FBR response according to the connector path; acceptance must be verified from the response.

### Who can do this

You need access to FBR/tax settings, terminal/location, item/customer tax, and POS sale permissions.

### Before you start

Complete tax-integration preparation and get approved sandbox endpoint, token/credentials, POS/branch IDs, scenarios, and test data.

### Check your work

One local test invoice maps to one accepted FBR reference and all quantities, taxable values, rates, taxes, and totals agree.

- Do not retry a timeout before checking FBR status by reference.
- Resolve invalid registration, item, unit, tax, or scenario mappings at source.
