The features are easy enough that even those with less tech savvy can manage them effectively, which makes this tool great! It's also flexible in terms of being able to adapt as your business grows or changes (which it will). I appreciate how simple they have kept things by allowing me not only choose my own time off but be allowed flexibility within certain parameters like paid/unpaid days etc., all without having an HR department constantly asking questions about what we're doing wrong here so please make sure you do everything correctly first before reporting any issues! Not much yet since our implementation was fairly basic other than some customizations required after initial setup - nothing major though just minor adjustments needed once implemented at scale.- Customization process took longer then expected- Some customization may require more work / expertise from developer side because there isn't many guides outthere regarding setting.
