My company recently opened a new commercial money market account. Our owner used a company check to make the first deposit into the money market account. Ideally he would have made a transfer but he didn't.

I'm not sure how to record the transaction. The check was written from our business checking account to the new money market account. When I try to write a check the money market account isn't an option under "Pay to the order of" (since it is set up as a bank account not a vendor.)

How can I properly record this transaction?
