# Filing GSTR-6: Import Purchase Register

To reconcile ISD invoices with GSTR-6A, import the ISD purchase register into Octa GST. This may also be referred to as
the **Inward Credit Register** or **Purchase Register of ISD**.

Download the purchase template from Octa, fill all mandatory fields, and upload the completed file. After upload, Octa
can compare your purchase data with the GSTR-6A data fetched from the GST portal.

The import flow is similar to the GSTR-2B purchase register import. For detailed import steps, see
[Import Purchase Register](https://octagst.com/octa/docs/app/gstr2b-reconciliation/import-purchase-register).

> **Tip:** The GSTR-6A purchase template includes a **Distribution List** column. Use this column when an invoice should be distributed only to selected recipient GSTINs instead of all recipients.
>
> For example, if an ISD invoice relates to only two branches, enter only those GSTINs in the Distribution List. Octa will
> then distribute the credit only to the selected GSTINs.

## Edit Purchase Document After Upload

If only a few invoices need correction after import, you do not need to upload the entire purchase register again. Edit
the required documents directly in Octa.

1. Go to the **Purchase** section.
2. Search by **Invoice Number** or **GSTIN**.
3. Select the document from the search results.
4. Click **Edit**.
5. Update the required fields.
6. Click **Save**.

This allows you to correct specific invoices without re-uploading the entire purchase data.
