Frequently Asked Questions
How do I generate a GST-compliant invoice?
Use the GST Invoice Generator — enter your GSTIN, buyer GSTIN, HSN/SAC codes, item details, and the tool automatically calculates CGST+SGST (intra-state) or IGST (inter-state) and generates a print-ready invoice. All mandatory GST invoice fields (Place of Supply, invoice serial number, tax breakup) are included.
What is the difference between gross profit and net profit?
Gross Profit = Revenue − Cost of Goods Sold (COGS). Net Profit = Gross Profit − Operating Expenses − Taxes − Interest. The Profit Calculator computes both, plus gross margin % and net margin %. Use the Margin Calculator to reverse-calculate: if you know the desired margin, it tells you the selling price to set.
How is construction cost calculated per square foot in India?
Residential construction costs in India range from ₹1,200-1,800/sq.ft (economy), ₹1,800-2,500/sq.ft (standard), and ₹2,500-4,000+/sq.ft (premium). The Construction Cost Calculator uses built-up area, specification grade, and city tier to estimate the total project cost including material, labour, and overhead — before architect and interior costs.
