Invoice Generator इनवॉइस जेनरेटर

A professional invoice does more than request payment — it is a legally compliant document that records a business transaction, enables your client to claim Input Tax Credit (ITC), and protects both parties in case of any dispute. For GST-registered freelancers in India, issuing a proper tax invoice is mandatory for every transaction above ₹200.

What Must a GST Invoice Contain?

Under the GST Rules, a valid tax invoice must include all of the following elements:

• Supplier details: Your full name or business name, GSTIN, and address
• Recipient details: Client name, GSTIN (if they are GST-registered), and address
• Invoice number: Unique, sequential number within a financial year
• Invoice date: Date of issue
• Description of services: Clear description of work done
• SAC code: Service Accounting Code for the type of service provided
• Taxable value: The value before GST
• GST rate and amount: Showing CGST + SGST (intra-state) or IGST (inter-state) separately
• Total amount payable: Including all taxes

Intra-State vs Inter-State: Which GST Applies?

The type of GST depends entirely on where your client is located, not where work is performed. If your client's registered business address (as in their GSTIN) is in the same state as yours, it is an intra-state transaction and you charge CGST + SGST (each at half the applicable rate). If the client is in a different state, it is inter-state and you charge IGST at the full applicable rate. For most freelancers charging 18% GST: intra-state means 9% CGST + 9% SGST; inter-state means 18% IGST.

When Must You Issue an Invoice?

For services, a tax invoice must be issued within 30 days of the date of supply of the service. The date of supply is generally the earlier of: (a) the date of invoice, or (b) the date of receipt of payment. In practice, most freelancers issue invoices at the completion of work or at monthly billing cycles. For continuous services (like a monthly retainer), invoice at the end of each month's service period or at agreed billing milestones.
