BBP okay at 90% util? Or pay early/prepay?

[wasCB14]

I have a Blue Business Plus coming in the mail. $9k SL for a sole proprietorship. I expect to spend about $8k on it within a few days of getting it.

Is it best to pay the total balance shortly after the big transactions post to minimize AA risk on a new account? I hear the card doesn't report, so I don't know if single-card utilization is a concern.

Should I push a payment (from a personal checking account I've used to pay personal Amex card for 2 years) before the transactions even post?

Or, given that I have 4 clean years of history with Amex, should I just hold onto the cash until the actual due date and not worry about the 90% utilization?

Considering your established history with AMEX I think it would be okay to hold onto the cash if that works better for you. Me personally even on non-reporting card the 90% UTL would be an itch on the back of mind that would have me inching my fingers to the payment screen.

I do feel the itch...and I don't even have the card yet!

I've got history with them, they just did my annual "backdoor FR" with Schwab, and my other Amex cards have trivial balances. Maybe I will pay on the actual due date.

Or maybe I'll take advantage of the 15 months at 0%...though I'm not quite sure if I'd be asking for trouble at some point.
