Small Business Tools FAQ

Small business owners need tools to manage stock (inventory calculator), track spending (expense tracker), plan finances (budget planner), accept payments (UPI QR generator), number invoices (invoice number generator) and brainstorm branding (business name generator). All six are free with no sign-up.

Use our UPI QR Payment Generator - enter your UPI ID, shop name and optional amount, and click Generate. Works with Google Pay, PhonePe, Paytm and all UPI apps. Download as PNG or print directly for your counter.

Use our Expense Tracker - add expenses by category (Rent, Utilities, Inventory, Staff, Marketing etc.) with a date and amount. See monthly totals, category breakdown chart, and export to CSV. Data is saved to your browser - no cloud account needed.

The 50/30/20 rule suggests spending no more than 50% of income on needs, 30% on wants and saving at least 20%. Our Budget Planner checks your income and expenses against these thresholds and highlights where you are over or under budget.
