# Installation

Installing GST Manager takes about 5 minutes. There are no code edits, no files to upload, and no license keys to enter.

*Shopify App Store → Add app*

## Step 1 — Install from the App Store

1. Open **GST Manager** on the [Shopify App Store](https://apps.shopify.com).
2. Click **Install app** (or **Add app**).
3. Review the permissions and click **Install**.
4. The app opens embedded directly inside your Shopify admin under **Apps → GST Manager**.

## Step 2 — Complete the Quick setup wizard

On first open, the app launches a **4-step Quick setup wizard**:

1. **Tax & GST identity** — enter your 15-character GSTIN, legal business name, and default GST rate (usually 18%).
2. **Address & contact** — verify your registered address and contact email.
3. **Invoice numbering** — choose your invoice prefix (e.g. `INV-` or `INV-FY-`) and starting number.
4. **Customer GST preferences** — choose whether to show the GSTIN input on your cart page.

Click **Finish setup**. See the [Onboarding guide](/gst-manager-shopify/guides/onboarding) for a detailed walkthrough of each step.

## Step 3 — Set Shopify taxes to 0%

GST Manager calculates GST directly from your product prices. To prevent Shopify from adding extra tax on top at checkout:

1. In Shopify admin, go to **Settings → Taxes and duties**.
2. Set India (and every state/region rate) to **0%**.
3. Turn off **"Include sales tax in product price"** and **"Charge tax on shipping rates"**.

See [Configure Shopify taxes](/gst-manager-shopify/guides/tax-setup) for the complete walkthrough.

## Step 4 — Enable the cart GSTIN block (optional)

If you want customers to enter their GSTIN on your store:

1. In Shopify admin, go to **Online Store → Themes**.
2. Click **Customize** next to your active theme.
3. In the left sidebar, click **App embeds** (the third icon).
4. Turn on **Collect Customer GST**.
5. Click **Save** in the top right.

## Step 5 — Place a test order

1. Place a test order on your storefront.
2. In Shopify admin, open **Apps → GST Manager → Orders**.
3. Click your test order to preview and download the generated tax invoice.
4. Check that the CGST/SGST or IGST amounts match your expectations.
