About Business Tools

Business tools help you create professional documents, calculate pricing, and manage common tasks without expensive software. Generate an invoice, calculate a discount, build a profit margin analysis: these tools handle the routine work so you can focus on running the business.

Common Uses

  • Create and download a professional invoice as a PDF without a subscription
  • Calculate the selling price needed to hit a target profit margin
  • Work out the discounted price and savings for a promotion or sale
  • Generate a QR code for a product, menu, or payment link

Tip

For invoices, always include a clear payment due date, your payment method details, and a unique invoice number. These three things reduce the time it takes clients to pay and make it easier to track outstanding invoices.

What you can do
