In fast-paced environments like Realtor Cleaning Services chicago, documenting the final phase of a cleaning job is essential. A digital checklist provides accountability, ensures service quality, and builds trust between cleaning providers and real estate professionals.
This post explains how to build a Python script that creates a digital checklist, converts it into a QR code, and displays it for technicians to scan, sign off, or review on the spot—ideal for mobile verification during property turnover.
Why Digital Checklists Matter in Cleaning Workflows
When executing Realtor Cleaning Services in chicago, you need verifiable steps to ensure that key zones like kitchens, bathrooms, HVAC units, and high-touch surfaces are cleaned and inspected. Traditional paper checklists are easily lost, while QR-linked forms can:
- Be updated in real time
- Provide timestamps and GPS metadata
- Track technician completion across locations
With Python, we can automate QR generation and optionally upload the data to a cloud backend like Google Sheets or Firebase.
Tech Stack
-
qrcode: for generating QR images -
Pillow: for displaying or saving images -
json: to structure the checklist -
uuid: to generate unique checklist IDs
Install the required libraries:
pip install qrcode[pil]
Python Code Example: generate_checklist_qr.py
import qrcode
import uuid
import json
from datetime import datetime
def generate_checklist():
checklist = {
"id": str(uuid.uuid4()),
"timestamp": datetime.now().isoformat(),
"tasks": [
"Sweep and mop floors",
"Wipe down all countertops",
"Clean inside and outside of appliances",
"Sanitize bathrooms",
"Dust all surfaces",
"Dispose of all debris"
],
"status": "pending"
}
return checklist
def generate_qr_from_checklist(checklist):
data_str = json.dumps(checklist)
qr = qrcode.make(data_str)
qr.save(f"{checklist['id']}_checklist.png")
print(f" QR saved as {checklist['id']}_checklist.png")
if __name__ == "__main__":
checklist = generate_checklist()
generate_qr_from_checklist(checklist)
This will create a PNG image with the encoded checklist. It can be scanned by mobile devices, linked to a cloud-based dashboard, or printed and left on-site.
Pro Tips for Field Implementation
- Pair QR scans with simple mobile forms (Google Forms or Typeform) for feedback.
- Store signed checklists in a shared drive with property address labels.
- Add fields like technician name and completion time dynamically.
- Print on waterproof stickers for harsh environments.
Use Case: Real Estate Turnovers
For companies offering Realtor Cleaning Services chicago il, this tool can be a game-changer. You create QR checklists on the fly, assign them to techs, and verify each completed job with a scan.
