We were planning on surfacing the number of available clients for TaxFolder on the TaxCycle start page where you see the update notifications and the licensing information:
Happy to get feedback on this. Also, we posted a reminder to clean up clients in TaxFolder prior Jan 1 to free up space for new clients. That is here: Pre-Season Planning Tip: Manage Your TaxFolder Client List - TaxCycle
The ability to merge clients is climbing up the list for priority but is not yet on our roadmap. Add your voice to this product suggestion here The ability to merge clients in TaxFolder .
For the purge option, please add this in the Suggestions category if it is not already there. This allows other community members to vote this idea up and we can gauge relative importance and impact for planning purposes.
