Income adjustment after closing out 2013 books in simply accounting

SUGGESTED

Dear Sir or Madam,

We have closed our 2013 books in simply accounting and unfortunately we need to adjust income. We do not want to do it through retained earning account because then it will be a reflected correction in 2014 and we want to do it in 2013.

Can you please help us how we can go about it to do it in 2013?

Thanks so much for your assistance.
