Finance and Accounting Automation - Invoice Due Date Reminder

 Notes:

• What problem does it solve?: It automatically sends reminders for overdue or upcoming invoices.

• How can businesses benefit from customizing the code?: Customizing reminder thresholds (e.g., 3 days before due date, 7 days after overdue) can ensure timely payments.

• How can businesses adopt the solution further?: Extend the tool to automatically generate reminders and send them via email or text message using APIs.

Actual Python Code:

from datetime import datetime, timedelta

class InvoiceReminder:

    def __init__(self, invoice_date, customer_name, email):

        self.invoice_date = datetime.strptime(invoice_date, '%Y-%m-%d')

        self.customer_name = customer_name

        self.email = email

    def send_reminder(self):

        today = datetime.today()

        due_date = self.invoice_date

        days_left = (due_date - today).days

        if days_left <= 7 and days_left >= 0:

            print(f"Reminder sent to {self.customer_name} at {self.email}: Invoice is due in {days_left} days.")

        elif days_left < 0:

            print(f"Reminder sent to {self.customer_name} at {self.email}: Invoice is overdue by {-days_left} days.")

        else:

            print(f"No reminder for {self.customer_name}: Invoice is due in {days_left} days.")

# Example usage

reminder = InvoiceReminder(invoice_date="2025-04-01", customer_name="John Doe", email="john.doe@example.com")

reminder.send_reminder()
