AI API with a GST invoice (₹)

GST invoices for AI spend — ITC claimable

Every unoblox top-up comes with a GST tax invoice, and your usage dashboard itemizes models, tokens, and ₹ amounts. If your business is GST-registered, AI API costs qualify as input-tax credit (ITC) — reducing your net tax liability. No other AI gateway in India offers this.

How GST invoices work

Example: You top up ₹10,000 of credit in September. GST is added on top of the top-up amount.

Invoice date:    the day of your top-up
GSTIN:           unoblox (07XXXXXX…)
Your GSTIN:      Yours (07XXXXXX…)

Line item:
  Prepaid AI API credit   ₹10,000
  ―――――――――――――
  + CGST (9%):    ₹900
  + SGST (9%):    ₹900
  ―――――――――――――
  Total paid:     ₹11,800

(Outside Delhi, the GST is a single 18% IGST line: ₹1,800.)

On your own GST return, claim ₹1,800 as ITC (input tax). Your ₹10,000 wallet credit is then spent on any model, and usage is itemized by model in your dashboard.

ITC eligibility checklist

• Your business is GST-registered (consult your accountant).
• AI spend is for business (not personal hobby).
• You file GST returns regularly (GSTR-1, GSTR-3B).
• Invoice is in your GSTIN's name.
• You claim ITC within the window your own GST filings require (confirm with your CA).
• HSN 998311 is on your ITC reconciliation list.

Frequently asked questions

Q: Will ITC actually reduce my tax? Yes. ITC = input tax paid. If you owe ₹100K tax and claim ₹10K ITC, you owe ₹90K. (Consult your CA for your specifics.)

Q: What if I'm not GST-registered? You still get invoices for bookkeeping. ITC benefit only applies to registered businesses.

Q: Can I backdate invoices? No. A GST tax invoice is issued at each top-up, for the amount credited.

Q: Do unoblox's own models (Embedding, Reranker) count? Yes. They're ₹0 but still itemized on the invoice for compliance.

Q: What if my monthly spend is <₹20? Minor invoices still issue. Some GST software auto-filters small amounts.
