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")
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.
