How can you develop great small Business accounting skills?

First of all I think you should have good knowledge in both Business and accounting, Second try to get more experience by training.
Finally try to follow the development in this particularly subject and every thing relative to it.

Small businesses have the following options when deciding how to keep their accounting records: They can do manual accounting themselves (by learning bookkeeping); they can learn to use accounting software such as Peachtree and use it for day-to-day accounting recordkeeping.
If they choose to use accounting software, they would still need to learn basic bookkeeping to enable them to use the software efficiently; They can hire a part-time accountant to take care of the accounting records; they can out-source their business's accounting records to accounting service firms.
Which option they choose would depend on the size of their business, their own accounting knowledge, their budget, etc.
To develop accounting skills, they should first study basic bookkeeping and practice it well to master it.
Afterward, if they want to use an accounting software, they can take a course in accounting software.
One simple and good accounting book that small business owners can use to learn accounting is my e-book "Accounting for Beginners" available from amazon.com http://www.amazon.com/dp/B00B2BSTV8
