  • Net 60: Payment is due within 60 days of the invoice date.
  • 1/10 Net 30: A 1% discount is offered if payment is made within 10 days; otherwise, full payment is due within 30 days.

Use CheckYa to send invoices

1. Input Parameters:

Invoice Date: Begin by entering the date when the invoice is issued to the client, we set astarting point for calculating the due date.

Payment Terms: Select the payment terms agreed upon with your client. Common options include Net 30, Net 60, 2/10 Net 30, among others. If your terms are different, you can input custom terms as needed.

2. Calculation Method:

Business Days vs. Calendar Days: Choose the calculation method that best suits your preferences and business practices.

Business Days: Opting for business days ensures that weekends (Saturdays and Sundays) and public holidays are excluded from the calculation. This aligns with typical working schedules and provides a more accurate representation of when payments are due within a standard workweek.

Calendar Days: Selecting calendar days includes all days in the calculation, regardless of whether they fall on weekends or holidays. This option provides a simpler approach but may result in due dates falling on non-working days.

3. Calculation Process:

Once you’ve inputted the invoice date and payment terms, our calculator uses an algorithm to determine the due date.

For example, if you issue an invoice on January 1st with Net 30 terms, and you’ve selected business days, the calculator will add 30 business days to January 1st to determine the due date.

If you’ve chosen calendar days instead, the calculator will add 30 calendar days to January 1st to calculate the due date.

4. Results:

After performing the calculation, the calculator will display the exact due date for your invoice. This ensures clarity and transparency, allowing you to communicate payment deadlines effectively to your clients.
