7 Free Online Tools Every Small Business and Freelancer Needs
Running a small business means wearing many hats: invoicing, pricing, tax, payroll and paperwork. These free browser tools handle the everyday math and documents — with no subscriptions, no signups and no data leaving your device.
1. Create professional invoices in minutes
The free Invoice Generator builds a clean, printable invoice with your business details, line items, tax rate and discount. The preview updates live, and "Print / Save as PDF" produces a watermark-free document ready to email to a client.
2. Get GST and VAT right every time
Whether you need to add 13% VAT to a quotation or work out how much tax is inside a tax-inclusive total, the GST / VAT Calculator does both — with one-tap preset rates for Nepal, India, the UK and Australia.
3. Price products with a healthy margin
Margin and markup are not the same thing, and confusing them quietly eats profit. The Profit Margin Calculator shows margin, markup and profit from your cost and selling price — or tells you exactly what to charge to hit a target margin.
4. Compare pay and rates fairly
Is a monthly salary offer better than your hourly freelance rate? The Salary Converter translates any amount between hourly, daily, weekly, monthly and yearly pay using your real working hours.
5. Convert currencies with daily rates
For international clients, the Currency Converter uses daily European Central Bank reference rates across 30+ currencies — ideal for quoting and invoicing across borders.
6. Understand loans and growth
Before financing equipment or expansion, check the real monthly cost with the EMI Calculator and see how savings compound with the Interest Calculator.
7. Label your products
Generate CODE128 or EAN-13 barcodes for inventory and price tags with the Barcode Generator, and scannable links or Wi-Fi codes with the QR Code Generator.
