Clerk

Clerk is a web-based invoicing platform designed for freelancers and small business owners who want to streamline their billing workflow. It lets users create and send professional invoices in seconds, track payment status, and manage client information—all from one dashboard. The platform includes an AI assistant that understands your invoicing data and can create invoices, answer questions about outstanding payments, and set up recurring billing through natural language commands.

Key features include automatic PDF invoice import that extracts client and amount details, real-time view tracking to see when clients open invoices, and a free tier supporting up to 10 invoices monthly and 5 clients. The maker built it with AI agents.
