For the majority of our customers the pricing will not change. We have a very small subset of our customers that exceed the 250 clients within their WHMCS that this will impact. Those customers we will be reaching out to directly in the coming weeks to secure an alternative approach for them. At this time we're still awaiting WHMCS to release their API changes necessary for us to even begin checking this.
For a short version, those customers above 250 clients will see a price increase, and/or alternative method of license delivery. At this time we don't know what those final numbers will be, but WHMCS has pretty much given no choice in this matter. They want more $ and will get it out of what they consider larger usage customers.
