# Settings reference

Every setting lives under **Apps → GST Manager → Settings**, grouped into section pages. Each page
saves with Shopify's **Save / Discard** bar. This is the field-by-field reference; for a guided
walkthrough see [Configuration](/gst-manager-shopify/configuration).

## Business Settings

| Field | What to enter | Default |
| --- | --- | --- |
| **Business legal name** | Your registered legal entity name; shown in the invoice supplier block | *(from Shopify)* |
| **Primary GSTIN** | Your 15-character GSTIN (uppercased) | *(from onboarding)* |
| **Registered state** | Your GST state; the GSTIN prefix sets it | *27 — Maharashtra sample* |
| **Phone number** | Shown in the supplier block on invoices | *(empty)* |
| **Contact email** | Shown in the supplier block on invoices | *(from Shopify)* |

**Refresh** pulls store legal name, contact email, and the Default location's address from Shopify;
it leaves GSTIN and state alone.

## Tax Configuration

| Field | Values | Default |
| --- | --- | --- |
| **Tax scope** | *Tax only products marked taxable in Shopify (recommended)* · *Tax all products (override Shopify's taxable flag)* | Taxable only |
| **Default GST rate (%)** | Used when a product has no rate; 0–28 | **18** |
| **I sell clothes and/or footwear** (slab rule) | On/off | Off |
| **Selling price — Lower slab (₹ per unit)** | Threshold; at/below it the product's Minimum GST % applies | **1000** |
| **Apply GST to shipping charges** | On/off | Off |
| **Shipping GST rate (%)** | Rate for the shipping line | **18** |
| **Shipping HSN / SAC code** | SAC printed against the shipping line | **9968** |

## Invoice Configuration

| Field | Values | Default |
| --- | --- | --- |
| **Invoice prefix** | Supports the `FY` token (`INV-FY` → `INV-2025-26-0001`) | **INV** |
| **Credit note prefix** | Same template rules | **CN** |
| **FY start month** | 1–12 | **4** (April) |
| **B2CL threshold (₹)** | Inter-state non-GSTIN orders above this go to GSTR-1 B2CL | **250000** |
| **Minimum invoice digits** | Zero-padding, 1–10 | **4** |
| **Start with custom number every FY** | On/off | Off |
| **First invoice number for financial year** | ≥ 1 | **1** |
| **Brand logo** | PNG/JPEG/WebP/GIF/SVG, ≤ 200 KB | *(none)* |
| **Authorized signature** | Transparent PNG recommended, ≤ 200 KB | *(none)* |
| **Disclaimer text** | Free text on the invoice footer | *(empty)* |
| **Show MRP (Compare-at price) on invoices** | On/off | Off |
| **Lock invoice contents at issuance** | On/off *(Pro)* | Off |
| **Issue one Tax Invoice per shipment** | On/off *(Pro)* | Off |
| **Date format** | DD-MM-YYYY · DD/MM/YYYY · MM-DD-YYYY · YYYY-MM-DD | **DD-MM-YYYY** |
| **Currency format** | `₹ 1,234.50` · `Rs. 1,234.50` · `INR 1,234.50` · `1,234.50` | **₹ {{amount}}** |

## Store Locations *(Pro for more than one)*

Each dispatch location holds a **Shopify location** link, **GSTIN**, **state**, and **address**. The
row that matches Shopify's **Default location** is the primary one and can't be deleted (edit it
instead). Adding more than one location requires the **Pro** plan.

## Integrations → Email Delivery

| Field | Values | Default |
| --- | --- | --- |
| **Enable email delivery** | On/off | Off |
| **Send Tax Invoice / Credit Note / Proforma** | Per-document toggles | Off |
| **BCC list** | Comma-separated addresses | *(empty)* |
| **Delivery route** | *Send via GST Manager* · *Use your own email* *(Pro)* | GST Manager |
| **Own transport** *(Pro)* | Resend · SMTP | Resend |
| **From email / From name / Reply-to** | Sender identity | *(empty)* |

Sending via GST Manager uses the app's own sender (`invoice@gstmanager.relyweb.co`). Using your own
Resend or SMTP credentials requires the **Pro** plan.

## Other Settings — Customer GST preferences

| Field | What it does | Default |
| --- | --- | --- |
| **Allow customers to provide a GSTIN** | Shows the cart-page GSTIN block | **On** |
| **Allow a customer to use multiple GSTINs across orders** | Off = lock to the customer's previous GSTIN | **On** |
| **Use Shopify B2B Companies as canonical GSTIN source** *(Pro)* | Read GSTIN from `CompanyLocation.taxRegistrationId` | Off |
| **Let B2B Company customers download Proforma PDFs** *(Pro)* | B2C customers never see Proforma either way | Off |
