GST
GST charged and paid, GSTR-1 data, marketplace sales and filing.
Please reach out to your account manager to enable GST for your company.
Overview
The GST page shows the GST you charged and paid, prepares your GSTR-1 data, and keeps marketplace sales and TCS separate.
Why use it
- See GST payable before you file.
- Download GSTR-1 for the portal.
- Lock a month once it is filed.
Before you begin
- Your GSTIN is set in Settings → Company profile.
Your GST, before you file
The GST page is enabled for your company on request. It brings everything your accountant asks for into one place:
| Report | Use it for |
|---|---|
| GST sales register | Every taxable sale, invoice by invoice |
| GSTR-1 summary and HSN summary | The figures for your GSTR-1 return |
| Documents issued and Credit notes | The document tables of GSTR-1 |
| Input GST (purchases) | Checking your input credit against GSTR-2B |
| Marketplace sales and TCS | Sales made through marketplaces and the tax they held back |
| GST payable by month and GST amendments | Trends, and changes to months already filed |
The GST page
- Net output GST: the GST you charged buyers this month.
- Input tax credit: the GST you paid on supplier invoices this month. Check it against GSTR-2B on the portal.
- Estimated GST payable: output minus input, or the credit to carry forward.
- Effective GST rate: the average GST rate across everything you sold.
- Charts of output against input over 12 months, taxable value by GST rate, and by supply type (B2B, B2C large, B2C small, exports).
- Marketplace sales and TCS: tax the marketplaces kept from your payouts, which you claim back on the GST and income tax portals.
Before you begin
- 1Add your company GSTIN in Settings → Company profile. Warehouses with their own GSTIN are filed under it.
- 2Under Marketplace GSTINs, enter the GSTIN of each marketplace in each state you are registered in. GSTR-1 uses them for marketplace sales.
Where sales GST comes from
- Your own store and wholesale orders: O2M's own tax invoices.
- Shopify: the tax lines Shopify recorded on each order (use Refresh from Shopify for a month).
- Amazon: the Merchant Tax Report (B2B or B2C), requested from Amazon or uploaded from Seller Central.
- Other channels: upload the channel's tax report and map its columns once; the mapping is kept.
When a channel's report for a month is imported, it replaces the order-based figures for that channel and month, and orders missing from the report are listed.
Registers and GSTR-1
- Sales register, Documents issued, HSN summary, Credit notes and Input GST (purchases) are available as reports.
- Download GSTR-1 as the portal JSON, with the offline-tool CSVs, in one ZIP.
- Credit notes are numbered for refunded returns of orders O2M invoiced.
Marking a month as filed
After filing, click Mark as filed. O2M keeps the filed figures; later changes to that month are shown as amendments instead of changing what you filed.
