Import Sales Register

Octa uses your sales register (all your outward supplies/invoices) to automatically prepare accurate GSTR-1, handle reconciliations, calculate correct tax liability, and generate summaries — saving you hours of manual work every month!

You can bring in sales data from any source (Amazon, Flipkart, your ERP like Tally/Busy, website sales, offline invoices, etc.) and in multiple formats — Octa combines everything perfectly into one clean GSTR-1 return.
