I like that the software is very easy to use. It is very clear with the explanations in the tutorials. The software is very customizable, and you can make it fit your specific needs. I dislike that sometimes the software is slow to load, and the tutorials do not always walk you through the process. I highly recommend OptiModel to anyone who is looking for a software that will help you out with your sales process. I am using OptiModel to help me with my sales process. I am able to do everything from creating my customer quotes, to billing, to invoicing, and more. I am able to create my customer quotes, and I am able to create my invoices.
