What each tool does

The GST calculator adds GST to a price or takes it out of an inclusive price, and shows the CGST and SGST (or IGST) split with the formula. The GST invoice generator makes a printable tax invoice with HSN codes, the right tax split for the place of supply, amount in words and a UPI QR code. The HSN code finder searches HSN and SAC codes by product name or number and shows the GST 2.0 rate. The GSTIN checker tells you at once whether a GST number is valid, which state it belongs to and the PAN inside it.

HSN codes and GST rates for the products shops ask about most:

HSN code for medicines HSN code for medical equipment HSN code for spectacles & optical HSN code for readymade garments HSN code for footwear HSN code for fabrics & textiles HSN code for home textiles HSN code for mobile phones HSN code for mobile accessories HSN code for computers & laptops HSN code for consumer electronics HSN code for home appliances HSN code for electrical goods HSN code for hardware & building materials HSN code for paints HSN code for furniture HSN code for stationery & books HSN code for cosmetics HSN code for personal care & toiletries HSN code for jewellery HSN code for sweets & mithai HSN code for bakery products HSN code for namkeen & snacks HSN code for ghee & butter HSN code for dairy products HSN code for grocery & kirana HSN code for edible oils HSN code for spices HSN code for dry fruits & nuts HSN code for tea & coffee HSN code for beverages & drinks HSN code for chocolates & confectionery HSN code for fruits & vegetables HSN code for restaurant services HSN code for salon & spa services HSN code for hotel rooms HSN code for professional services HSN code for repair & laundry services HSN code for bicycles HSN code for auto parts HSN code for kitchen utensils HSN code for pooja items HSN code for baby care & hygiene HSN code for tobacco & pan masala

About these free GST tools

Are the Billux GST tools really free?

Yes. The GST calculator, GST invoice generator, HSN code finder and GSTIN checker are free to use with no sign-up and no limit on calculations, invoices or offline GSTIN checks. Only the optional business-name lookup on the GSTIN checker has a small hourly limit, because each lookup costs us a paid API call.

Do these tools store my business data?

No. All four tools run in your web browser. The invoice generator keeps your draft and seller details in your own browser storage so they are there next time, and nothing is uploaded to Billux. The only exception is the optional GSTIN name lookup, which sends just the GST number you ask about.

Are the GST rates updated for GST 2.0?

Yes. The calculator offers the GST 2.0 slabs of 0, 5, 18 and 40% plus the special 0.25% and 3% rates, and the HSN code finder follows Notifications 9/2025 and 10/2025-Central Tax (Rate), effective 22 September 2025. Each HSN page shows the date the list was last checked.

Billing every day?

Billux does all of this automatically on every bill — GST split, HSN, UPI QR and WhatsApp bills from the counter. 7-day free trial, no card needed.
