Free GST Billing Software Explained: New 2026 Rules for Indian Shops

Free GST Billing Software is the digital solution that enables Indian shopkeepers, retailers, and service providers to create GST-compliant invoices without manual paperwork, directly supporting GST compliance under the 2026 rules. It automatically calculates CGST, SGST, and IGST, assigns sequential invoice numbers, and generates e-invoice data for the e-Way bill system, eliminating calculation errors and record-keeping headaches. For a neighborhood kirana store or a service-based salon, this means moving from handwritten registers to a secure, cloud-based system that updates in real-time on desktop and mobile devices. The Khata Billing — free GST billing software delivers this functionality at zero cost, with the free plan covering 10 invoices per day and 100 invoices in any 30-day period, using basic invoice themes and barcode generation. It replaces physical invoice books and manual tallying, allowing shopkeepers to print thermal receipts or standard A4 invoices directly from the device. By digitizing the billing process, it ensures every transaction is instantly recorded for GST filing, reduces paper waste, and streamlines stock tracking for small inventories. This shift from paper to digital is essential for MSMEs to meet GST law requirements while saving time and avoiding penalties.

Free GST Billing Software meets new 2026 GST invoice rules requiring 12 mandatory fields including GSTIN, legal name, address, HSN code, invoice date, sequential numbering, and barcode. Free plan users can generate up to 10 invoices per day and 100 per 30-day period using a barcode-based Free GST invoice generator that auto-creates standard barcodes for items. This prevents manual entry errors and ensures GST compliance. For example, a Delhi-based kirana store selling 5 kg apples (HSN 0808, 12% GST) at ₹50/kg receives a 50-kg invoice: 5 kg × ₹50 = ₹250, CGST 6% = ₹15, SGST 6% = ₹15, total ₹280. The system prints a barcode on A4 sheets for thermal printer scanning, updates stock in real-time, and displays party balances on the dashboard. Manual billing still requires handwritten HSN codes and sequential numbers, risking penalties under Section 11 of CGST Act. Khata Billing's free plan covers 10 invoices daily with 4 custom fields per item type, while Premium adds unlimited invoicing, watermark-free PDFs, and GSTR-1 filing support. Always consult a CA for GST filing decisions.

Creating your first GST-compliant invoice with free GST Billing software takes just six steps, designed for Indian shop owners to follow without confusion. Step 1: Log in to your Khata Billing dashboard and click 'New Invoice' to start fresh. Step 2: Enter customer details like GSTIN, name, and address as required by GST law. Step 3: Add items from your inventory by selecting from saved products or typing the HSN code and quantity, then input the rate in INR. Step 4: The software automatically calculates CGST, SGST, or IGST based on your product's tax slab, showing the total tax amount and invoice value. Step 5: Generate the barcode by clicking 'Print Barcode' which creates a scannable code for the invoice number and enables thermal printer support. Step 6: Review the invoice with correct invoice numbering and click 'Save' to store it in your party ledger, then use the Khata Billing blog for GST rule updates. These steps ensure your shop meets GST compliance while using the free plan's 10 invoices per day and 100 per 30-day limit, with basic invoice themes and barcode printing that matches GST requirements without watermarking or premium features.

Manual billing using a register or paper log requires shopkeepers to write each GST invoice by hand, calculate CGST, SGST and IGST separately, and then manually update stock levels, which often leads to transcription errors and delayed inventory reconciliation. In contrast, digital GST billing workflows capture the invoice details directly from the POS billing system, auto-calculate tax components, generate a correct invoice number, and instantly adjust stock quantities based on item rates and HSN codes, eliminating most human errors and saving valuable time at the billing counter.

Consider a typical day at a Mumbai retailer: a manual process might take 5 minutes per invoice for writing, tax calculation, and stock entry, resulting in 15 minutes lost for just three invoices. With automated GST billing, the same three invoices are created in under 2 minutes, with taxes auto-applied and stock reduced immediately, freeing the shop owner to focus on customer service or restocking. The accuracy of digital records also supports precise input tax credit claims and smoother GSTR-1 filing, reducing the risk of audit discrepancies. While Khata Billing's free plan covers 10 invoices a day, up to 100 in any 30-day period, the real efficiency gain comes from the automated workflow that handles each transaction without manual intervention, ensuring consistent stock valuation and reliable financial data for MSMEs.

Open the Khata Billing dashboard and click Manage Inventory to activate the free inventory module; this enables stock tracking for all your products without any additional setup cost.

Follow these steps:

1. Go to the Items tab in the dashboard
2. Click Import to add up to 5 items at a time from a CSV file or enter them manually
3. Assign each item an HSN code and select a stock type such as perishable or durable

For Point of Sale setup, navigate to POS Settings and enable the billing screens option; the free plan supports up to 2 screens simultaneously, allowing you to split sales between a main counter and a secondary register.

To configure multi-screen POS:

• Connect each device to the same Wi‑Fi network as the central server
• Log in with the same Khata Billing credentials on each device
• Enable the “Sync Stock in Real Time” toggle to update inventory across all screens instantly

When you reach the 5‑item import limit, purchase additional items through the Premium upgrade to unlock bulk import of up to 2000 items, which removes the daily restriction and lets you scale your shop inventory efficiently.

Khata Billing's free GST Billing Software enforces strict invoice limits to ensure fair usage of its core services. The free plan allows exactly 10 invoices per day, and within any rolling 30-day period, the total cannot exceed 100 invoices. For example, if you issue 10 invoices on the first day, you can issue 10 more on the second day, but after the 10th day you must wait for the next 30-day window to reset the count. This rolling 30-day calculation prevents businesses from gaming the system by issuing high volumes early in the month. Once the 100-invoice limit is reached, any additional invoice attempts will be blocked until the next cycle begins. These limits apply to all invoice types, including standard, GST-compliant, and barcode-printed invoices. The restriction is designed to protect small traders who issue moderate volumes while preventing high-volume operations from using the free tier indefinitely. To remove these caps, businesses upgrade to Premium, which includes unlimited invoicing with no daily or monthly restrictions. The upgrade also unlocks advanced GST reports, GSTR-1 filing support, and unlimited accounts, making it the natural next step for growing shops, retailers, and service providers who need seamless GST compliance without manual workarounds.

To demonstrate how GST is calculated and invoice totals are generated within the Free GST Billing Software limits, consider a sample shop invoice for a 30-day period using exactly 10 invoices, which matches the free plan’s daily cap and 100-invoice monthly limit.

1. Invoice Details: A shop sells 5 units of Item A (HSN 8517) at ₹200 each and 2 units of Item B (HSN 8515) at ₹150 each. The subtotal is ₹1,300 (5 × ₹200 + 2 × ₹150). CGST of 9% and SGST of 9% apply, so tax is ₹234 (₹1,300 × 0.09 × 2). The total becomes ₹1,534.
2. GSTIN Entry: The shop owner logs the GSTIN on the invoice, which is required for input tax credit eligibility under GST law.
3. Input Tax Credit: When the shop purchases ₹500 worth of goods from a supplier with a valid tax invoice, the ₹45 CGST and ₹45 SGST paid can be claimed as input tax credit, reducing the net GST liability for the period.
4. Generating the Invoice: Within the Free GST Billing Software daily limit of 10 invoices, the shop creates this invoice, prints a barcode, and saves it. The software automatically calculates the tax and updates the stock quantity for Item A and Item B in the inventory module.
5. Stock & Reporting: After the sale, the shop adjusts the stock levels, and the basic reports show the updated stock overview and party balances without any premium features.

By staying within the 10‑invoice‑a‑day and 100‑invoice‑per‑30‑day free plan boundaries, the shop can fully manage GST calculations, claim input tax credit, and generate compliant invoices using the Free GST Billing Software.
