Free Nexavolt Tools: An Operator's Toolkit, No Login Required

Running a business is a steady stream of small calculations — what to charge, how much tax to add, what a deal really nets, how long the runway lasts. Most of these don't need a spreadsheet or a subscription; they need a clean tool that gives you the right number in seconds. That's exactly what the free Nexavolt tools are for. No login, no limits, no catch.

What's in the toolkit

• Invoice & Quotation Maker — professional, tax-ready invoices, quotations and proforma with a branded PDF export.
• GST / VAT Tax Calculator — add or remove tax for any country, including India's CGST/SGST/IGST split and reverse (tax-inclusive) calculations.
• Pricing & Margin Calculator — work backwards from the margin you want to the price you should charge.
• Fundraising & runway tools — burn rate, runway and the early-stage math founders reach for most.
