Frequently Asked Questions

Are all the tools on this page completely free?

Yes. All the free tools on this page — including the GST calculator, invoice generator, barcode generator, SKU generator, HSN code search, profit calculator, credit and debit note generator, reorder point calculator, business loan EMI calculator, and bill book designer — are completely free to use with no account required.

Do I need to sign up to use these tools?

No sign-up is needed to use any of the free tools on this page. You can access the GST calculator, barcode generator, HSN code search, and all other tools directly without creating an account. If you want to connect these tools to your actual inventory and billing data — so that invoices, stock levels, and reports are all linked — you can sign up for a free Wiseventory account.

How accurate is the GST calculator?

The GST calculator on Wiseventory uses the current GST tax slabs as notified by the Government of India. It correctly calculates CGST and SGST for intra-state supplies and IGST for inter-state supplies based on the tax rate you enter. For complex transactions involving exemptions, reverse charge mechanism, or composite supply, always verify with your chartered accountant as GST rules can vary by product category and business type.

Can I use the invoice generator for real business billing?

The free invoice generator is great for one-off invoices or testing purposes. For regular business billing with automatic inventory deduction, customer history, GST reports, and purchase tracking, we recommend using the full Wiseventory billing software. The full platform connects your invoices to your stock, purchases, and financial reports automatically, saving significant time compared to generating invoices manually one by one.

What is an HSN code and why do I need it?

HSN stands for Harmonised System of Nomenclature, an internationally recognised system for classifying goods. In India, HSN codes are mandatory on GST invoices for businesses with a turnover above specified thresholds. The correct HSN code determines the applicable GST rate for your product and must appear on all B2B invoices. Use the Wiseventory HSN code search tool to find the correct 4-digit, 6-digit, or 8-digit code for your products.
