How to account for credit card purchase with both a cc account and "central bill account"

GLOPLLC

My business credit card account (with US Bank) is accompanied by a "central bill account" that, for my solo business, essentially acts a the sole sub account of the central bill account.

My question is what bookkeeping transactions do I need to account for a credit card purchase?

My downloaded transactions resulting from a credit card purchase include both a debit to the credit card account and a debit to the central bill account in the same amount.

Later when I make a payment to the central bill account (to pay off the credit card for multiple purchases) the transaction I see is a credit to the central bill account.

How do I categorize these transactions?

Thank you!
