A simple invoice planning page for taxable value, GST amount, total invoice value and invoice checklist.
Invoice Generator
Use this page as a practical planning guide and verify official rules before final use.
Formula: Invoice Total = Taxable Value + GST Amount. GST Amount = Taxable Value x GST Rate / 100.
Invoice Details That Reduce Payment Confusion
A clear invoice should show seller details, buyer details, invoice number, date, item description, quantity, rate, discount, tax rate, total, payment terms, and notes. For GST invoices, HSN or SAC details and correct tax breakup are important.
Use the calculator as a working estimate and keep source documents nearby. If the number will be used in payroll, accounting, tax filing, or a customer document, compare the result with the latest rule, company policy, or invoice format before final use.

Detailed explanation
The Invoice Generator helps prepare a draft total before issuing a bill. It is especially useful when you know taxable value and GST rate but want to check the final amount.
Use this page as a preparation step, not as a final authority. The calculator or checklist can make the working easier, but payroll, GST and invoice details should still match official records.
Example situations
| Taxable value | Base amount before GST. |
|---|---|
| GST amount | Tax calculated on the base amount. |
| Invoice total | Amount payable after adding GST. |
Invoice example notes
If taxable value is Rs. 10,000 and GST rate is 18%, GST amount is Rs. 1,800 and invoice total is Rs. 11,800. If the quote is GST-inclusive, calculate the taxable value separately before issuing the final invoice.
| Situation | What to check |
|---|---|
| Quotation | State whether GST is included or extra. |
| Final invoice | Check GSTIN, invoice number, date, HSN/SAC and place of supply. |
