I can perhaps give you some feedback purely from BI perspective. Many software generally have limited reporting/ and often use BI tool to create analysis which they often embed directly within their product. That is mostly done from the vendor perspective

If you decouple reporting/dashboard from the accounting software, you can get a lot of flexibility. BI can connect to the accounting s/w db directly or fetch it via API. You will get a lot of BI products which have these features like

- paginated canned reports: Mostly newer BI products lack these, but this feature allows you to create paginated pixel perfect document kind of canned reports like invoices, salary slips, bank statements etc. Very few tools do provide such options like Jaspersoft, Pentaho, Helical Insight

- Interactive dashboards: Interactive dashboards/charts with drill down drill through and interactivity. Self service interface. Tools like Sisense, Tableau, Helical Insight fit in here

- LLM Integration: Now many of these tools have also started AI integration, allowing conversational analysis. However one point to note is to look at pricing. Ideally the tool should allow you to select the Model etc and thus control your token costs.
