GST Invoice Guide for Hyderabad Businesses & Freelancers (2026)
Freelancers and small businesses registered in Telangana use GST state code 36 as the first two digits of their GSTIN — getting this wrong on an invoice is one of the most common (and most avoidable) compliance mistakes.
GST invoicing basics for Hyderabad businesses
Any business registered in Telangana carries the state code 36 as the first two digits of its GSTIN. This single detail decides whether a transaction is treated as intra-state (CGST + SGST) or inter-state (IGST) — and getting it wrong is one of the most common reasons an invoice gets flagged during a client's own GST reconciliation.
What's different about invoicing from Hyderabad
Hyderabad's business landscape leans heavily on IT/ITES and pharma, centred around HITEC City and Gachibowli. pharma vendors in Hyderabad often deal with multi-state distribution, making the HSN code field on the invoice more important to get right than in a purely local-services business
Building a compliant invoice, step by step
- Confirm your GSTIN begins with 36 (for Telangana) and double-check the buyer's GSTIN state code too — don't assume it matches their office address.
- Decide CGST+SGST vs IGST based on the *place of supply*, not just the billing address on the client's letterhead.
- Use a sequential invoice number series per financial year, as required under GST rules — this matters even more if you invoice several Hyderabad clients from the same series.
- Fill in the correct HSN/SAC code for your goods or service category — this is checked more closely for B2B invoices than B2C.
- Generate the invoice with Utility Hub's free GST Invoice Generator, export to PDF, and keep a static copy — banks and auditors in Hyderabad routinely ask for a saved copy, not just a shareable link.
When to double-check with a CA
This guide covers the standard GST invoice format used nationwide, including in Telangana. For anything involving exports, reverse charge, or composition scheme, confirm the specifics with your CA before sending the invoice to a client.
