GST Billing Software for Indian Businesses
Prepare Indian GST invoices, review tax calculations, and follow the sale through payment and reporting. This page covers Indian GST wherever you are browsing from; other tax systems have a separate invoicing guide.
From company setup to a reviewed GST invoice
- In Company Settings, check the legal business details, GSTIN, address, state, invoice prefix, and tax-inclusive or tax-exclusive pricing. Have your accountant verify the registration and tax setup.
- Create or review the customer, including GSTIN where applicable and billing and shipping details. Check the transaction's actual place of supply rather than assuming that a postal address settles every tax question.
- In Sales > Invoices, select the customer and add products or services. Review units, quantity, rate, discount, HSN/SAC, and the applicable tax rate before saving.
- ZentBill uses the company and customer state settings for CGST/SGST versus IGST calculations. Check the result against the transaction's tax treatment, then save and inspect the generated PDF.
- Record the payment against the invoice, retain references for partial payments, and use the relevant return or credit-note workflow for adjustments. Review records with your accountant before filing.
Illustrative worked example
Illustrative arithmetic only, not a rate recommendation: assume an ordinary intra-state taxable sale of 10 units at INR 500 each, no discount, tax-exclusive prices, and an applicable GST rate of 18%. Taxable value is INR 5,000; CGST at 9% is INR 450 and SGST at 9% is INR 450, giving INR 5,900 total. For an otherwise equivalent inter-state transaction subject to IGST, 18% IGST would be INR 900. Confirm classification, place of supply, and the actual rate separately.
What to verify before relying on this workflow
General product and tax guidance, not professional tax advice. A saved PDF is not proof of successful GST filing or e-invoice registration. Special supplies, exemptions, reverse charge, composition treatment, e-invoicing, and e-way bill requirements need separate checks. Ask your accountant to verify current local rules and filings; confirm any required integration with support before relying on it.
Check current official information through the GST portal and CBIC GST portal. These are authority starting points, not certification of a particular transaction or this software.
Frequently asked questions
Does the GST page change to a different tax system outside India?
No. This URL explains Indian GST. Use the worldwide tax-invoicing solution for company-country and local-tax setup considerations.
Can I record a partial payment?
Yes. Record the customer payment against the invoice and review the remaining balance. The payments documentation explains allocation and payment references.
Does changing a product's tax rate fix earlier invoices?
No. Existing invoices retain their original values. Review the appropriate correction or credit-note workflow with your accountant instead of assuming a catalog edit changes issued records.
