OIS (Open Invoice System) was established to give our customers the ability to see their statements online, in real-time, and even look at invoice images. The screens are easy to read and easy to understand. Here at YES, we thought of this electronic invoicing system as an opportunity to reduce the cost of doing business with us. Through an automated E-mail system, we have integrated a tool to notify you of new invoices on your account and past dues invoices on your account. This allows you to experience a worry-free invoicing process so you don’t need to log in everyday, let us do the work for you. ![]() |
