I'm Earning Passive Income Selling Python Scripts — Here's Exactly How

If you've been writing Python for a while, you probably have dozens of scripts sitting in folders you never look at. I did too. Then I packaged them up and started selling them. Here's the full story.

The Idea

About 6 months ago I was automating my own small business — sending invoices, tracking expenses, monitoring competitors, generating reports. I wrote a bunch of Python scripts to handle all of it.

One day a friend asked if I could share the scripts. Then another friend. Then a client. That's when I realized: these things have real value.

I packaged them into a toolkit and listed it for sale. Within the first week I had my first buyer.

What's Actually in the Toolkit

The Python Business Automation Toolkit contains 12 production-ready scripts:

1. Invoice Generator

Pulls from Google Sheets or CSV, generates PDF invoices, sends them via email. Handles recurring invoices, late payment reminders, and tracks who has paid.

# Generate invoice for client
invoice = InvoiceGenerator(
    client_name="Acme Corp",
    items=[{"description": "Python consulting", "hours": 10, "rate": 150}],
    due_days=30
)
invoice.send_to("billing@acmecorp.com")
Enter fullscreen mode Exit fullscreen mode

2. Competitor Price Monitor

Scrapes competitor websites every 6 hours. Sends alerts when prices change. Tracks price history in SQLite.

3. Lead Generation Scraper

Extracts business contacts from Google Maps and industry directories. Deduplicates and exports to CSV.

4. Email Automation Suite

Automated follow-up sequences, drip campaigns — all from plain Python, no paid tools required.

5. Social Media Scheduler

Posts to Twitter and LinkedIn from one script. Schedule a week of content in 30 minutes.

6. Expense Tracker + Tax Report

Categorizes bank transactions automatically using keyword matching. Generates monthly P&L.

7. Customer Support Automation

Routes support emails, generates AI-assisted draft responses, tracks ticket status.

8. Business Dashboard

Real-time Streamlit dashboard pulling data from Stripe, Google Analytics, Shopify, or any API.

9. PDF Report Generator

Turns any data (sales, analytics, inventory) into polished PDF reports on a schedule.

10. Inventory Alert System

Monitors inventory levels, auto-generates purchase orders when stock drops below threshold.

The Numbers

  • Time to build: ~40 hours over 2 months (evenings/weekends)
  • Price: $29 one-time
  • Recurring cost: $0 (no subscription, no API fees for core features)
  • Time it saves: 10-20 hours/month for most small business owners

Why $29?

I priced it at what I'd charge for one hour of consulting. If even one script saves you 2 hours, it's already paid for itself many times over.

No monthly subscription. No upsells. One payment, all scripts included, plus any updates.

What I Learned About Passive Income

"Passive income" is a bit of a misnomer. The passive part is the sales. The work is building something genuinely useful — not just a tutorial.

The scripts I built solved real problems I had. Don't build what you think people want. Build what you desperately needed and couldn't find.

Get the Toolkit

The full Python Business Automation Toolkit — all scripts, documented, production-ready — is available at:

One-time payment of $29. Instant download. Works on Python 3.8+.

If you buy it and any script doesn't work for your use case, I'll either fix it or refund you. No questions asked.
