Finance and Accounting Automation - Automated Invoice Generator

 Notes:

• What problem does it solve?: Manages the invoicing process by automating the creation of invoices based on product/services and customer details.

• How can businesses benefit from customizing the code?: Businesses can automate invoice generation by integrating with their product or service management system, reducing human error.

• How can businesses adopt the solution further?: Extend the system by integrating payment gateways, providing real-time invoice tracking, or adding a feature to handle recurring payments.

Actual Python Code:

import pandas as pd

from datetime import datetime

class InvoiceGenerator:

    def __init__(self, customer_name, product_details, invoice_date=None):

        self.customer_name = customer_name

        self.product_details = product_details

        self.invoice_date = invoice_date if invoice_date else datetime.today().strftime('%Y-%m-%d')

    def generate_invoice(self):

        total_amount = sum([item['quantity'] * item['unit_price'] for item in self.product_details])

        invoice = {

            'Customer Name': self.customer_name,

            'Invoice Date': self.invoice_date,

            'Products': self.product_details,

            'Total Amount': total_amount

        }

        return invoice

    def display_invoice(self):

        invoice = self.generate_invoice()

        print("Invoice Summary:")

        print(f"Customer: {invoice['Customer Name']}")

        print(f"Invoice Date: {invoice['Invoice Date']}")

        print("Products:")

        for product in invoice['Products']:

            print(f"  {product['name']} x {product['quantity']} = ${product['quantity'] * product['unit_price']:.2f}")

        print(f"Total Amount: ${invoice['Total Amount']:.2f}")

# Example usage

product_details = [{'name': 'Laptop', 'quantity': 2, 'unit_price': 500},

                   {'name': 'Mouse', 'quantity': 3, 'unit_price': 20}]

invoice = InvoiceGenerator("John Doe", product_details)

invoice.display_invoice()
