  and legacy CSVs alongside it.

# File your GSTR-1

When it's time to file, GST Manager gives you the CSV data you need for your return. This walkthrough
takes you from picking a date range to a downloaded **GSTR-1** file, explains the B2B and B2C rows,
and shows the companion exports you can pull alongside it.

::: info What GSTR-1 is
GSTR-1 is your outward-supplies return. GST Manager's report puts your **B2B** (customers with a
GSTIN) and **B2C** (customers without one) invoices into a single CSV so you can prepare it.
:::

## Step 1 — Watch the due countdown

On the [dashboard](/gst-manager-acellemail/features/dashboard), the **GSTR-1 due** countdown shows
when your next return is due, so you know when to start. Open **GST Manager → Reports** when the date
approaches.

## Step 2 — Pick your date range

In **GST Manager → Reports**, each report has a **From / To** date-range picker. Set the range to
your filing period (for example, the calendar month you're filing for). The Reports page is where you
*"Download CSV exports for compliance filings."*

## Step 3 — Download the GSTR-1 (B2B & B2C) CSV

Next to **GSTR-1 (B2B & B2C)**, click **Download CSV**. This report puts *"B2B (with GSTIN) and B2C
(no GSTIN) on a single CSV with a Section column."* Open it and read the **Section** column to tell
the two apart:

* **B2B rows** — invoices to customers who have a GSTIN, captured as validated on the
  [contact page](/gst-manager-acellemail/guides/gstin-validation). These carry the customer GSTIN
  and belong in your B2B tables.
* **B2C rows** — invoices to customers with no GSTIN. These are your consumer sales and belong in
  the B2C section of your return.

## Step 4 — Pull the companion exports

For the rest of your filing, use the other two reports over the same date range:

* **Export invoices** — *"Only invoices flagged as export (billing country ≠ India)."* Download this
  for your export supplies.
* **Legacy — all paid invoices** — *"Every paid invoice across the date range — domestic + export,"*
  useful as a reconciliation cross-check.
