# Invoices & tax

> GST invoices for INR workspaces — the tax details printed on them, when you're asked for a GSTIN, how to download invoices and credit notes — and how invoicing works for USD workspaces through Paddle.

---

How you're invoiced depends on your workspace's [currency](/operate/credits#your-workspace-currency):

| | INR workspace | USD workspace |
|---|---|---|
| Who issues the invoice | Amomic-AI, as a GST tax invoice | Paddle, our merchant of record |
| Tax | 18% GST, added to every payment | Sales tax or VAT, worked out by Paddle at checkout |
| Where to find it | **Billing → Billing history → Download** | **Billing → Billing history → Paddle invoice** |
| Tax details in the console | Yes | No. You enter them at Paddle's checkout. |

The rest of this page is about INR workspaces, apart from the [USD section](#usd-workspaces) at the end. Owners and admins can see and download invoices. Only the owner can change tax details.

## What you're charged

Every INR payment, whether a plan renewal, an upgrade or a credit top-up, is the price plus **18% GST**. Prices in the console and on [Plans & limits](/operate/limits) exclude GST. Each payment dialog shows the split before you pay. For example, Growth is ₹7,999 + ₹1,440 GST = **₹9,439**.

On a credit top-up, the GST is charged on top of the amount you choose and is never spendable: pay ₹2,950 and ₹2,500 lands in your balance.

The console shows a single **GST 18%** line. Your invoice splits it as either **CGST + SGST** or **IGST**, depending on the state you're billed in.

## Tax details

**Billing → Tax details** holds what's printed on your GST invoices. Set it **before** you pay. An invoice is issued at the moment of payment and can't be reissued with different details.

| Field | What it's for |
|---|---|
| **Registered name** | Your legal entity name, for example *Veloria Home Appliances Private Limited*, not your workspace name. Required for any payment of ₹50,000 or more. |
| **State** | Your place of supply. Decides whether your invoice shows CGST + SGST or IGST. **Required** before any payment. |
| **Billing address** | Printed on the invoice. Required once you add a GSTIN, and for any payment of ₹50,000 or more. |
| **GSTIN** | Optional. Add it to claim the GST back as input tax credit. Your state is filled in from it. |

Click **Save tax details**: *Tax details saved. They'll appear on your next invoice.* When everything an invoice needs is on file, the card shows **Ready for invoicing**.

If the GSTIN and the state don't match, saving is refused and the message names both states, for example *that GSTIN is registered in Karnataka, but the state selected is Rajasthan*. Correct whichever one is wrong.

Admins see these fields but can't edit them.

## When you're asked for these details

You're prompted at three points, so a missing GSTIN never slips through unnoticed:

1. **A bar at the top of Billing** while no GSTIN is on file: *Your plan and credits are charged with 18% GST. Add your GSTIN to have it appear on your tax invoices and claim it as input tax credit.* The X hides it in this browser.
2. **Add your GSTIN?** before a plan payment, if there's still none on file. Choose **Add GST details** or **Skip for now**. You pay the same GST either way.
3. **State you're billed in** in every payment dialog (plan and top-up). You can't pay until a state is chosen. Your choice is saved to Tax details.

The same dialogs ask for a **Registered name** or **Billing address** when this payment needs one and it isn't on file, and say why above **Pay**. **Save invoice details** saves them to Tax details.

::: tip Add the GSTIN before your first payment
A GSTIN added later only appears on later invoices. Invoices already issued keep the details they were issued with.

## Downloading invoices

**Billing history** lists every payment:

| Column | What it shows |
|---|---|
| **Period** | The billing period. A credit top-up shows a single day, such as *2026-09-24 → 2026-09-24*. |
| **Amount** | The total paid, including GST |
| **Status** | **paid**, or the payment's other state |
| **Invoice** | **Download** for the PDF |

Plan renewals and credit top-ups both appear here, each with its own invoice. Invoices are numbered in one series per financial year, for example `AMO/26-27/00418`.

If a download says *That invoice is missing tax details we can't add retrospectively*, the invoice was issued before your tax details were complete. Write to support@amomic.in with the invoice period and we'll sort it out.

## Credit notes

When a payment is refunded, in full or in part, we issue a **credit note** against the original invoice. It reverses the GST on that invoice. Credit notes appear under **Credit notes → Refunds** once you have one:

| Column | What it shows |
|---|---|
| **Credit note** | The number, such as `CN/26-27/00007`, with a **Partial** badge for a part refund |
| **Date** | When it was issued |
| **Against invoice** | The invoice it reverses |
| **Amount** | The refunded amount, *incl.* the GST it reverses |
| **Document** | **Download** for the PDF |

Give your accountant the credit note together with the original invoice. If you've already claimed input tax credit on that invoice, the credit note is what reverses it.

Refund terms are in the [Refund & Cancellation policy](https://amomic.in/refund-policy).

## USD workspaces

Paddle is the merchant of record for USD workspaces. It calculates, collects and pays the sales tax, VAT or GST for your location, and it **issues the invoice and receipt itself**:

- Billing history shows a **Paddle invoice** link instead of **Download**.
- There's no Tax details card, GSTIN bar or credit notes section.
- If your business is VAT-registered, enter your VAT ID at Paddle's checkout.

## Troubleshooting

**I paid without my GSTIN. Can the invoice be reissued?** No. An invoice can't be reissued with different details. Add the GSTIN now and it will appear on every invoice from the next payment on.

**The Pay button is disabled.** Choose **State you're billed in** in the dialog. It's required on every GST invoice. If a state is already chosen, the invoice needs more: a **Billing address** when a GSTIN is on file, or a **Registered name** and **Billing address** for a payment of ₹50,000 or more. The dialog shows the missing fields, and the line above **Pay** names them. Fill them in and choose **Save invoice details**.

**I can't see Billing history or Tax details.** They're visible to owners and admins only. Ask your workspace owner.

**My invoice shows IGST, but I expected CGST and SGST.** The split follows the state on file. Check **State** in Tax details before your next payment.
