How does BillNest decide between CGST/SGST and IGST?

From your GSTIN and the buyer's place of supply: intra-state orders get CGST + SGST, inter-state orders get IGST. Compensation cess and tax-inclusive prices are handled too.

Does BillNest file my GST returns?

No. It exports GSTR-1 and GSTR-3B data (Excel and JSON) plus a CSV invoice register; you file on the GST portal as usual.

Does it generate e-invoices (IRN / QR)?

Not yet. Where e-invoicing is mandatory for your turnover, you still generate the IRN through an authorised system; BillNest produces the Rule 46 tax invoice and the supporting documents.

Is there a free plan?

Yes: 50 invoices a month, generated automatically as Shopify creates each order, with credit and debit notes included. Paid plans raise the monthly cap and add automatic emailing, custom branding, proforma invoices and delivery challans, GSTR-1 and GSTR-3B exports, bulk ZIP download, and per-GSTIN numbering for multi-branch sellers.

WHATWhat BillNest does

BillNest automatically creates a GST-compliant tax invoice for every order, applying the correct CGST and SGST for intra-state sales or IGST for inter-state sales, based on your GSTIN and the buyer's place of supply. It supports HSN and SAC codes, compensation cess, tax-inclusive prices, and gapless per-year invoice numbers. It also issues credit notes, debit notes, proforma invoices, delivery challans, and Bills of Supply, and exports GSTR-1 and GSTR-3B files for your GST returns.

Built for: Indian Shopify merchants who need every invoice to be GST-correct without a spreadsheet.
App Store category: Store management › Finances › Taxes

OUTPUTWhat BillNest produces

A GST tax invoice generated by BillNest: seller GSTIN and PAN, buyer in Maharashtra, place of supply 27-Maharashtra, supply type intra-state, three line items with HSN codes taxed at 12, 0 and 18 percent, and a summary showing taxable value 2,900 with CGST 210, SGST 210 and a total of 3,320 — The document itself: one order, three GST rates, and the tax shown as CGST and SGST separately rather than as a single total. This is the PDF a merchant's customer receives.

LOOKBillNest in the Shopify admin

BillNest's Invoices page with a tax invoice open over the list: invoice number INV/26-27/1000, place of supply 27-Maharashtra, supply type intra-state, three line items with HSN codes and per-line CGST and SGST, and buttons to view, regenerate, issue a debit note or download the PDF — Every document stays open from the list it lives in. Regenerate recomputes it in place and keeps its number; the series never gaps.
