Regulatory flexibility

Two operating modes, no forced overhead

A business below the registration threshold shouldn't have to deal with tax lines from day one. Deku has a pure accounting mode for it under section 22 of the CGST Act, and a GST mode for registered businesses. You choose the mode when the company is set up.

Pure accounting mode

Turnover below the registration threshold

For freelancers, professionals and small suppliers who don't need GST registration under section 22 of the CGST Act.

Bills of supply and commercial invoices with no tax lines.
A UPI QR code on the invoice, so customers can pay you directly.
Full double-entry books for income tax and your financial statements.
