Maybe try this to see if your company already is accumulating Business Extraa points on your behalf when you travel for work: After you book your next business trip through your normal methods with Concur, call the BE customer service line (which is basically meeting services) . If your company keeps a Business Extraa number stored in your profile, it should now be in the ticket that was booked through concur. Ask Business Extra customer service if they can verify if your BE number is stored in your record for that trip. If they say it's already entered, then your company is enrolled and accumulating credits on your behalf and obviously you shouldn't touch it or switch anything to stay compliant. But if it's blank, then if it was me, I'd feel free to put in the BE number for your side hustle biz, since BE is a freebie that your company has opted not to accept. Maybe your company isn't aware of BE being a freebie they COULD be getting, but if it's being forfeited anyway, you're certainly not taking away from your company anything that they're counting on getting from your business travel. I would just call and enter it for each business trip manually since your company may sign up at some future time.

My two cents.
