GST Invoice Guide for Lucknow Businesses & Freelancers (2026)
Freelancers and small businesses registered in Uttar Pradesh use GST state code 09 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 Lucknow businesses
Any business registered in Uttar Pradesh carries the state code 09 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 Lucknow
Lucknow's business landscape leans heavily on government, education, and a growing IT/startup base, centred around Gomti Nagar and Vibhuti Khand. many Lucknow-based consultants bill Delhi-NCR clients, making the IGST vs CGST+SGST decision one of the most common invoicing mistakes locally
Building a compliant invoice, step by step
- Confirm your GSTIN begins with 09 (for Uttar Pradesh) 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 Lucknow 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 Lucknow routinely ask for a saved copy, not just a shareable link.
