Frequently Asked Questions About GST Invoicing

Can I use BillSara if my business is not registered for GST?

Yes, absolutely. BillSara has a 1-click toggle for Non-GST and Composite scheme retailers. You can generate standard retail bills, estimation receipts, or delivery challans without any GST breakdown.

How does BillSara handle interstate transactions with IGST?

When generating a B2B invoice, BillSara compares your shop's home state with the customer's GST state code. It automatically applies CGST and SGST for intrastate sales, or IGST for interstate transactions without manual selection.

Can I export my monthly sales data for GST filing (GSTR-1)?

Yes. BillSara provides 1-click GSTR-1 summary spreadsheets formatted for direct sharing with your Chartered Accountant (CA) or tax consultant, categorizing B2B, B2C Large, and B2C Small sales with HSN summaries.

What happens if my shop starts as Non-GST and registers for GST later?

You do not need to switch software or migrate your data. Simply enter your new GSTIN in Store Settings. BillSara immediately switches future billing to legal GST tax invoices, while keeping all previous non-GST sales history intact.
