Overview
Small businesses need lightweight math before opening accounting software: quote margins, draft invoices, estimate sales tax on a proposal, and track whether a product line is profitable.
Invoice Generator and Receipt Generator produce client-ready drafts. Profit Margin, Profit, and Margin Markup calculators translate price and cost into markup decisions. GST Calculator and VAT Calculator help international quotes when you supply rates. Sales Commission Calculator models rep payouts you configure.
These are not ERP or bookkeeping systems. Export critical numbers to your accountant and use certified tax software for filings.
