That's cool. Have known the founder and liked their product and seemed relevant hence suggested.
Do check out Appsmith (https://github.com/appsmithorg/appsmith), I work here and we're an open source low code framework for building internal applications. We haven't really thought about the accounting use case, but now that you mention it, it could be super interesting (we've ofcourse had a lot of users building for HR, IT, Sales & Marketing use cases, other than the support).
