ThemeForest License question

I am sorry if this question doesn’t belong here but I thought someone might have experience with Themeforest and might know the answer to my quick question. If I wanted to buy a theme from them to use on my WordPress multisite would a “regular license” be enough ? I will be making their theme the default theme for each site on my network but wasn’t sure if this was considered one site to them for purchasing a regular license. thanks for any help you can provide!
