The only way to get ahead of your accounting department's workload is to document your internal procedures and build your organization in a way that would allow for it to operate without you.  Now, a lot of people may be asking, "if I did that, what would the company need me for?"  That is just the kind of thinking that is holding you back.  On the contrary, if your organization is dependent on you, then it is also limited by your abilities and availability which may be why you are currently working so much and watching your personal life go by out of the window of your office.  Read the book "The E-Myth Revisited."  The accounting department is the transaction hub of any organization and it is essential that it operates as efficiently and effectively as possible to ensure the ability of your company to scale. Work hard on bridging the gaps between tribal knowledge and global, world-class thinking…and then you may be able to go play a little!  

Six Sigma should be utilized in all SOX or process reengineering implementations.  Think of it this way, just as you would be expected to be graded when you go to school, you should also expect to grade your process reengineering effort which means you should set expectations ahead of time and then measure the output against these expectations.  If an ROI cannot be determined prior to starting the implementation, then perhaps the implementation direction is not clear or perhaps the project is not even necessary.  Vibato uses Six Sigma methodologies in all of our products and implementations.  Learn more about Six Sigma via this link:
