Well, I feel dumb. As an independent IT consultant I wear all of the hats in my business, including accounting. While doing an email server support upgrade for 2012 for a client yesterday, I discovered that I did not bill the K-12 school for $832 for a 2010 email server license upgrade and yearly support fee. It breaks out as the following:
Mail server support license renewal - $398, 25
Mail server 25 user upgrade license - $433.35.
It was a busy fall and the upgrades were performed in September and I just never billed them as it slipped through my accounting. So my question to you independent consultants out there is, How would you handle this at this late date?
