I like that it helps to keep track of my vendor's services/products we use for our agency in one place! It really makes keeping up with invoices easy when they are organized by category (and searchable!).
The reporting features could be more user friendly - perhaps add some filters or sorting options? This is not so much an issue as this would make using them easier overall- but maybe consider adding those sorts if you do decide there needs to be improvements here.- Keeping all your accounts current has never been simpler than being able to quickly find what was used last month vs 3 months ago etc..
