Acumatica is dedicated to flexibility in all elements of its programming. Because of this, they offer two choices for licensing methods.SaaS is an annual subscription license that is hosted in a public cloud. It’s a set monthly payment. With the subscription, Acumatica essentially takes on the role of IT for your company’s ERP needs. They handle upgrades and other maintenance and troubleshooting tasks.Private Cloud Subscription (PCS) gives you the same ERP but changes the hosting option. Instead of a public cloud like Amazon Web Services, your business can choose the cloud and hosting provider. Acumatica reports that the SaaS licensing is customers' most popular purchasing option. It’s a better option for smaller businesses that either doesn’t have an IT department or want their IT professionals to focus on different projects.The PCS licensing is the better option for those who want more control over the process. Beyond getting to choose your cloud and hosting provider, you also get to pick when updates happen.
