The business accounts won't show on your personal credit report unless payments are made late. Synchrony and Amex will typically require a PG, and when you PG that will be a HP inquiry on your personal credit report.
The consumer card offers deferred financing options, but is supposed to be for personal / consumer use only. The business card doesn't offer any promotional financing, but is geared specifically for business purchases.
There's an Amex option for businesses - I opted to get a regular Amex and the Lowe's Business card. While it meant two inquiries, and two accounts to manage, I keep the Lowe's purchases on a separate card.
I was going to garden... Honest!
