How to use these business and tax guides

The business guides are written for freelancers, shop owners and small companies who handle their own paperwork. They cover the documents that move a sale from enquiry to payment — the quotation, the tax invoice and the receipt — and the numbers that tell you whether the business is healthy: gross margin, markup, break-even volume, expenses, cash flow and stock levels.

If you are new to GST, read how GST is calculated and CGST, SGST and IGST first, then how to create a GST invoice. For pricing decisions, profit margin versus markup and the break-even point work well together. The record-keeping guides on expenses, cash flow and inventory show simple routines you can keep up every week.

GST rates, invoice rules and registration thresholds depend on the goods or services and on current notifications. The guides explain the method and point to the official GST portal and CBIC sources; confirm transaction-specific rules with those sources or a qualified professional.
