The Person Behind the Books
I've spent the better part of 30 years making complex systems run reliably — first in technology, now in small business finance. Even as a professional bookkeeper, I can sometimes still relate to that feeling of dread when facing a list of uncategorized transactions. That shared feeling is exactly why I work the way I do: no shortcuts, no "good enough." Just accurate, always current books from a bookkeeper who shows up.
