I know a lot of people get tired from chasing clients who don’t pay their invoices at the same time and some of them lost in the crowd and that cause a problem in cash flow, so I found a way to track unpaid invoices. It’s by AI Automation: 1. Make a workflow connected to your invoicing tool or CRM by N8N 2. Check daily the client with unpaid invoices and count 3. Grab the clients with 7, 14, 21… and push them into the workflow 4. Make templates for each category and make the AI make some personalization tweaks 5. Send polite reminder message automatically Now cash flow improves without awkward chasing. You save time, increase revenue without extra effort.
