The potential challenge, especially when considering a larger user base, is that the expenses can significantly add up. There are issues with integration and I encountered limits and warnings, especially with my pivot table size. It could potentially incorporate more functions in the future. Another point worth mentioning is related to graphing. When you have a large dataset, say a thousand customers, the bar chart might display only the first fifty or a hundred entries, making it less user-friendly for horizontal scrolling. Ideally, it would be more intuitive to scroll all the way to the right to view the last entries.
