Business tools help small business owners, freelancers and startups create invoices and quotations, calculate profit margins, break-even points, loan EMIs and ROI, and price freelance work — all free and running entirely in your browser with no upload, no signup, and no monthly subscription.
This cluster covers the recurring paperwork and math behind running a small business or freelance practice: generating a professional invoice or price quotation to send a client, working out profit margin and markup on a product, finding the break-even point for a new offer, calculating a loan or business EMI schedule, pricing freelance work by the hour, measuring the return on a marketing or equipment investment, and brainstorming a business name and slogan.
