About Alex
Google Sheets & Apps Script Automation | Invoice Reminders + AR Tracke
Keelung, Taiwan - 4:14 am local time
If overdue invoices are hurting cash flow, I can set up a hands-free payment reminder system in 48 hours.
What you get:
• A Google Sheets AR dashboard (due dates, status, reminder history, notes)
• Automated Gmail reminder sequence (pre-due → due → overdue → final notice)
• PayPal payment links embedded for 1-click payment
• Logging + stop rules (paid invoices won’t get reminded)
• A simple handoff guide so your team can maintain it
Typical use cases:
• Invoice/payment reminder automation
• Accounts receivable follow-up tracker
• Google Sheets + Gmail workflow automation
• Apps Script automation for recurring admin tasks
To start, I only need:
1) A sample invoice list (Sheet/CSV or 5 sample rows)
2) Your reminder cadence (Net-7/Net-14/Net-30, and how many reminders)
3) Your preferred tone (friendly vs. firm)
4) Your PayPal.Me link (base URL)
Fast, practical, and reliable. First working version delivered within 48 hours, with 1 revision included.
