We like the use of differentiating the U. Also please play around with other options with the Font. Happy to see other fonts which are different to standard.
Could you try one with Accounting incorporated into a one line logo. With the same font as upside.
Could you also do one with Upside and the Accounting words different fonts same size. But emphasising the Upside.
To develop your idea please think of using cocepts in some other larger brand names which also use the words solely as the logo.
If you could create a font just for us this will be viewed favourably. Similar to what you have done with the U above.
I would like to see a version of your logo with a arrow incorporated.
