Simple Invoice Generator is a free online invoicing tool built for freelancers, consultants, and small business owners who need professional invoices without the complexity of full accounting software.

Built by a solo founder out of frustration with existing tools that were either too expensive, too complex, or required setting up a full accounting system just to send a simple PDF.

The goal is simple: go from zero to a sent professional invoice in under 2 minutes. No setup, no credit card, no learning curve.

Free plan available with no time limit. Pro plan at $9/month or $79/year for unlimited invoices.
