Features
Invoicing and payment follow-ups, without the complexity.
Create invoices with AI, automate payment follow-ups, and see what you're owed—all in one simple workspace. PayFlowAI is built for freelancers, consultants, agencies, and small businesses, without the need for a dedicated finance team.
Natural Language Invoice Creation
Create an invoice by simply describing the work.
No more filling out every field from scratch. Describe the work, choose your client, and PayFlowAI drafts the invoice for you. Review the details, make any changes, and confirm when you're ready to send.
- Describe it in plain English. Tell PayFlowAI what you did, who the invoice is for, and how much to charge.
- Start with the details you already have. PayFlowAI matches your request to existing client information and drafts the invoice fields.
- Stay in control. Review and edit the details before confirming the invoice.

Can PayFlowAI match payments to invoices automatically?
