## 1. Business Settings

Your registered business identity appears in the supplier header on every invoice:

1. Open **Settings → Business Settings**.

## 2. Tax Configuration

Control how GST rates apply across your products:

1. Open **Settings → Tax Configuration**.

4. **Different GST % based on slab** — turn this on if you sell apparel or footwear. Enter your lower price threshold (e.g. ₹1,000). Products priced at or below this value will use their lower slab rate.
