Yes, depending on your contract, you have 100MB, 250MB, or 2000MB package creation / per month.
This rarely occurs, and usually only occurs when very large packages have been built many times in the same month.
If your group needs to upgrade your Submittal123 package, we'd be glad to do so. Contact our support team and we'll take care of that right away! support@Submittal123.com
