We have a free 30-day trial. Once you sign up, you can enter in your payment information any time in the first 30 days. We accept either credit cards that are charged monthly. Or, we can email you a monthly invoice payable by company check. Once your 30-day trial has expired, your credit card will be billed, or you will receive an emailed invoice. Credit card charges will receive an emailed receipt. If you would like to set up an annual payment, please contact us InOutBoard Contact Support or Sales.
