Our customers are asking for integration with a lot of their systems (say HR / patrolling), but never ever offer to hook up their accounting system. If we want financial data, we either get a PDF with their audited financial statement or in exceptional cases a custom audited statement (you know, the one where a print of a part of the ledger gets a signature from the CPA for a not insignificant bill).
So I am enthusiastic from a data science point of view. Financial data processing of customer data is / was scarce since limited to what was feasible to manually process. That is nearly in the past.
