CollectFlow —AI Invoice Collection Agent

What it does

CollectFlow is an AI-powered n8n workflow that automates invoice follow-ups. It checks overdue invoices daily, analyzes client email history, selects the right reminder tone, and creates or sends personalized Gmail reminders automatically. It also logs every action, sends daily Slack summaries, and prevents duplicate follow-ups. Perfect for freelancers, agencies, consultants, and small businesses.

Stop chasing unpaid invoices by hand. Let an AI agent do it — automatically, on schedule, with a full audit trail.Every unpaid invoice sitting past due is a business quietly financing its own client for free. CollectFlow is an n8n workflow that fixes this — it watches your invoices, decides when and how firmly to follow up, and sends the reminder without you lifting a finger.This isn't a "send an
