Cheapest GST Billing Software for Small Restaurants in India (2026)

Under the Goods and Services Tax rules, every GST-registered restaurant must issue a tax invoice for each supply. Failing to issue compliant invoices can lead to penalties during audits and difficulty filing returns. Here is what every restaurant GST invoice must contain:

• Name, address, and GSTIN of the supplier (your restaurant)
• Name and address of the recipient (and their GSTIN if the supply is B2B and above ₹50,000)
• A unique sequential invoice number for the financial year (e.g., INV/2025-26/00001)
• Date of issue
• Description of goods or services with HSN code or SAC code
• Taxable value of each item
• Rate of tax (typically 5% for restaurants)
• CGST and SGST amounts shown separately (or IGST for inter-state supplies)
• Total amount payable including tax
• Signature or digital signature of the authorised signatory

Manual invoice generation is error-prone, especially for restaurants doing 100+ orders per day. Each invoice must be numbered sequentially within the financial year — a mistake in numbering can cause mismatches in your GSTR-1 return. GST billing software automates this entirely.

The table below compares the main GST billing options available to small Indian restaurants. Competitor prices marked as 'Contact / varies' are not publicly listed — verify with each vendor before committing.

For small restaurants, the key differentiator is whether invoicing is fully automatic — triggered the moment an order is placed — or whether it requires manual entry. Manual entry solutions, regardless of price, introduce the risk of missed invoices and sequential numbering errors.

The sticker price of a billing solution is only one part of the total cost. Consider these factors:

• Auto-generation vs manual entry — software that creates the invoice automatically on every order prevents missed invoices and numbering gaps.
• Sequential FY numbering — invoices must be numbered in an unbroken sequence within the financial year. Any gaps invite scrutiny during a GST audit.
• HSN/SAC code accuracy — the software should either ship with restaurant-specific HSN codes pre-loaded or allow easy configuration with your CA.
• UPI and card payment integration — linking payment collection to the invoice prevents the mismatch between receipts and invoices.
• PDF export and print — restaurant owners often need to provide a paper receipt to walk-in diners. The solution should support A4 and thermal printer formats.
• GSTR-1 export — some platforms can export invoice data in the format required by the GST portal, saving accountant time.

Every order placed through Restrofi — whether via table QR code, counter order, or staff entry — automatically triggers a GST-compliant invoice. No manual action is required.

The invoice includes: your restaurant's GSTIN and registered address, sequential FY invoice number (e.g., RF/2025-26/00247), item-level HSN codes, the taxable value per item, CGST and SGST calculated at the correct rate, and a grand total. The PDF is downloadable and printable.

Restrofi's sequential numbering resets at the start of each financial year (1 April) and never skips a number, even if an order is cancelled — the cancelled invoice is voided with a note, which is the correct GST treatment.

Before you start issuing GST invoices through any software, complete these steps:

• Register for GST if your restaurant's annual turnover exceeds ₹20 lakh (₹10 lakh in special category states). Restaurants below this threshold are exempt but may register voluntarily.
• Obtain your 15-digit GSTIN from the GST portal (gstin.gst.gov.in). It will be required in every invoice.
• Enter your GSTIN in your Restrofi account settings under Business Profile. This auto-populates all future invoices.
• Confirm your applicable HSN/SAC codes with your CA. Most restaurant services use SAC code 9963.
• Decide your invoice number prefix for the financial year (e.g., RF/2025-26/) and configure it in Restrofi's invoice settings.
• Run a test order and verify the PDF invoice before going live to ensure all fields are correctly populated.

These steps take under an hour. Once configured, Restrofi handles every invoice automatically. Consult a qualified CA for GST rates and specific treatment applicable to your restaurant's situation.
