Single Member LLC, filing Sched. C - cash to accrual

[SunTaxMan]

Single member LLC, filing Schedule C (in 2006 and prior), crossed $1 Million Gross Sales in 2007. Change needs to be made from cash to accrual. Question:

Do I simply change the Schedule C from cash to accrual with no other comment?

Do I NEED to file 3115, since this is an "automatic" change?

I assume there is no fee for the change because it is "automatic" - correct?

Thanks,

TTB, page 8-23 says the following:

Once an accounting method has been established, a taxpayer needs IRS approval before the accounting method can be changed. This is true even if the taxpayer is required to change, such as a cash method taxpayer no longer able to use the cash method under one of the prohibitions.
