What is GST Billing Software?

GST billing software automates the creation of GST-compliant invoices, calculates all applicable taxes, and generates the reports needed for GST return filing — all from one place.

Under India's GST law, every registered business must issue a tax invoice showing GSTIN of both buyer and seller, HSN/SAC code, taxable value, GST rate and amount (split as CGST+SGST for intra-state or IGST for inter-state). Milaan ERP handles all of this automatically so you never make a compliance error.

Key GST Billing Features
