InvoiceAgent simplifies invoicing by transforming simple text descriptions of work into polished, professional invoices. It allows users to send these invoices directly from their Gmail account without needing a sign-up or subscription. The tool features an automated AI agent that sends follow-up payment reminders if clients do not pay on time. A free tier offers unlimited invoice generation, while the Pro version ($17/month) includes automatic payment collection and contract management with e-signatures.
