Understanding Invoices

What You Need to Know About Tax & GST Invoices

Everything you need to know about creating compliant invoices for your business

What is a Tax Invoice?

A Tax Invoice is a legal document issued by a registered business to its customers showing the details of goods or services supplied along with the tax charged. Under GST (Goods and Services Tax), it is mandatory for registered suppliers to issue a tax invoice for all taxable supplies.

A tax invoice serves multiple purposes:

  • It acts as proof of supply of goods or services
  • It enables the recipient to claim Input Tax Credit (ITC)
  • It contains all mandatory details as per GST law
  • It helps in maintaining proper business records
  • It is essential for GST return filing

Every tax invoice must include details like GSTIN of supplier and recipient, HSN/SAC codes, tax rates, taxable value, and breakdown of CGST, SGST, or IGST as applicable.

What is a GST Invoice?

A GST Invoice is a tax invoice that complies with Goods and Services Tax (GST) regulations in India. It is the primary document for all business transactions under the GST regime and must contain specific mandatory fields as prescribed by the GST law.

Key features of a GST-compliant invoice:

  • Unique Invoice Number (sequential numbering)
  • GSTIN of both supplier and recipient
  • HSN/SAC codes for products and services
  • Taxable value and tax rates
  • Breakdown of CGST, SGST, or IGST
  • Place of supply for interstate transactions
  • Reverse charge details if applicable

With invo, creating GST-compliant invoices is effortless. Our system automatically handles all calculations and ensures your invoices meet all legal requirements.

Tax Invoice vs Proforma Invoice

Understanding the difference between these two types of invoices is crucial for proper business documentation:

Tax Invoice
  • Issued after delivery of goods or completion of services
  • Legally binding document
  • Used for accounting and tax purposes
  • Required for claiming Input Tax Credit
  • Must follow sequential numbering
  • Contains actual transaction details
VS
Proforma Invoice
  • Issued before delivery or service completion
  • Not a legally binding document
  • Used for advance payment requests
  • Cannot be used for ITC claims
  • Acts as a quotation or estimate
  • Helps confirm order details

Q.04
What is the difference between Tax Invoice and Proforma Invoice?
A Tax Invoice is a final, legally binding document issued after goods/services are delivered and is used for accounting and GST claims. A Proforma Invoice is a preliminary bill sent before delivery, often used to request advance payment or confirm order details. It is not a legal document for tax purposes.
Q.05
How does invo calculate GST automatically?
invo automatically detects whether your client is in the same state or different state. For intrastate (same state), it splits the tax into CGST and SGST. For interstate (different state), it applies IGST. You just need to select the tax percentage, and we handle the rest.
Q.06
Do I need a GSTIN to use invo?
No. You can create proforma invoices and quotations without a GSTIN. However, to issue a formal Tax Invoice with tax breakdowns, a valid GSTIN registered under GST law is required, as it must appear on the invoice.
Q.07
Can I add my company logo and bank details to invoices?
Yes. invo lets you upload your company logo, add payment terms, notes, and bank details once — and every invoice you generate will automatically carry your branding and payment information.
Q.08
Is my business data safe with invo?
Absolutely. Your data is encrypted and stored securely. We never share your information with third parties. Bank-level security standards protect your business and client data at all times.
