If you were operating a business in the '90s this scenario is probably familiar: You purchase a desktop accounting software with some basic transactional tools. Then you spend dozens of hours issuing checks, recording invoices, and other basic obligations. Everything else, especially financial and compliance accounting, is sent off to your professional accountants.
This was the dominant mode of accounting pre-internet, and it didn't meet anyone's needs especially well. Business owners poured tons of time into accounting, but due to their lack of professional expertise the books were often incorrect and disorganized.
