Invoice Automation System

Overview

The Invoice Automation System is designed to automate the process of generating, uploading, and sending invoices via WhatsApp. This project utilizes several tools and libraries including PIL for image handling, Cloudinary for image uploading, Twilio for messaging, and docxtpl for document generation and manipulation.

Project Structure

The project consists of three main modules:

1. Invoice Manager: Handles the creation and formatting of invoices.
2. URL Generator: Uploads the invoice images to Cloudinary and retrieves the URL.
3. Message Manager: Sends the invoice URL to clients via WhatsApp using Twilio.

1. Invoice Manager

This module generates an invoice in .docx format, converts it to .pdf, and finally converts the .pdf to an image (.png).

• docx2pdf
• fitz
• os

Function

def invoice(template, name, logo, date, invoice_number, company_address, invoice_to, amount):
    # Implementation details here
    pass

2. URL Generator

This module uploads the generated invoice image to Cloudinary and retrieves the secure URL of the uploaded image.

Dependencies

Function

def get_url(image):
    # Function implementation here
    pass

3. Message Manager

This module sends a WhatsApp message to the client with the invoice URL using Twilio.

• os

Function

def message(url, name, date):
    # Function implementation here
    pass

cloudinary.config(
    cloud_name = 'your_cloud_name', 
    api_key = 'your_api_key', 
    api_secret = 'your_api_secret', 
    secure = True
)

Twilio Configuration

account_sid = 'your_account_sid' 
auth_token = 'your_auth_token'

from_number = 'whatsapp:your_twilio_number_here' 
to_number = 'whatsapp:client_number_here'
