Product specification
✓ Code verified — tested and runs clean
Automate your entire accounts receivable workflow and eliminate the manual stress of chasing late payments.
Freelancers and agencies often lose up to 20% of their billable hours purely on administrative tasks, with manual invoice tracking causing critical cash flow delays when payments slip through the cracks.
This Python script acts as a dedicated virtual assistant that monitors your invoice due dates and automatically sends professional payment reminders to clients via email. By tracking payment statuses in real-time and logging a complete history of all interactions, it ensures you get paid faster without ever having to write a follow-up message manually again.
What's included:
- Python Script (.py) -- Ready-to-run automation logic that requires no complex coding knowledge to operate.
- Automated Email Reminders -- Sends personalized, professional follow-up emails based on your custom schedule.
- Payment Status Tracking -- Instantly updates and categorizes invoices as pending, paid, or overdue.
- Interaction History Log -- Keeps a detailed timestamped record of every reminder sent for easy auditing.
- Customizable Templates -- Allows you to tailor the tone and content of your payment requests.
Who this is for:
Independent freelancers, specialized consultants, and creative agencies who manage multiple retainers or projects and need to stop wasting valuable billable time on repetitive administrative email tasks.
Real example:
A graphic design studio previously spent 4 hours every Monday manually checking bank statements and sending emails to 10 active clients with overdue invoices. After implementing this script, that admin time dropped to zero, and overdue payments were collected 40% faster due to consistent, automated communication.
What you'll achieve:
- Reduce time spent on invoice administration by approximately 10 hours per month.
- Decrease the average days sales outstanding (DSO) by ensuring no payment reminder is missed.
- Maintain a professional cash flow system that operates consistently without your daily input.
