# Importing Sales Register: Amazon Format

Octa makes GST filing effortless for Amazon sellers! With **direct import** of your **Amazon Monthly Tax Report (MTR)**
and **Amazon Stock Transfer Report (STR)**, Octa automatically pulls in your sales data, classifies transactions, and
prepares key parts of your **GSTR-1** — no manual conversion needed. Save hours of work every month!

## What Octa Processes Amazon MTR/STR Data?

After a successful import, Octa processes everything and auto-generates these GSTR-1 sections for you:

- **B2B** invoice-level details (with GSTINs, invoice numbers, etc.)
- **B2C** summary (total state-wise sales, taxes, etc.)
- **HSN Summary** (HSN-wise tax breakdown)
- **E-commerce Summary** (TCS details)

Ready-to-use for filing — just review and submit!

## How to Import?

### Step 1: Download Your Amazon MTR/STR File

1. Log in to your **Amazon Seller Central** account (sellercentral.amazon.in)
2. Go to **Reports** > **Manage Taxes** (or look for **GST Monthly Reports** section)
3. Select **Merchant Tax Report (MTR)** as the report type
4. Choose report type
   - Merchant Tax Report (MTR) - B2B
   - Merchant Tax Report (MTR) - B2C
   - Stock Transfer Report (STR)
5. Choose the **year** and **month** you need
6. Click **Download Report** — it usually comes as an Excel file (often named something like GST_MTR_B2B.xlsx or
   similar)

> **Tip:** Amazon typically makes the previous month's MTR available by the 5th of the current month. For exact steps, refer
> [this article](https://sellercentral.amazon.in/help/hub/reference/external/202171900?locale=en-IN) or check Amazon
> Seller Central's help section on GST reports (search for "GST Monthly Report" or "MTR" in Seller Central).

### Step 2: Import into Octa

1. Open your company in Octa
2. Go to the **Sales** page
3. Click the **Import** button
4. From the format dropdown, choose **Amazon Format**
5. Select the MTR Excel file you just downloaded
6. Select the **Period** (month/quarter) this file covers — match it to your GST return period
7. Click **Continue** and follow the simple on-screen prompts (Octa will guide you!)

That's it! Import usually completes in less than a minute.

## Quick Troubleshooting Tips

- Make sure the file is the correct MTR export (not a different report like payments or summary).
- If you get errors: Octa shows clear messages with row numbers — fix in your Excel file and re-upload.
- Need both B2B and B2C? Import each file separately — Octa combines them automatically.
- Need to import stock transfer data? Generate and import STR file — Octa will combine all data automatically.
