Claiming vs Changing author from admin

Hi,

Wanted to check on the following:

1. FOR A FREE PACKAGE: Assuming I have done the verifications, and a user has already an account (i am using Buddypress for account), then instead of asking them to claim the listing from front end, can i just change the OWNER, and the Post EXPIRE DATE in admin? Will this have any different behaviour than Submit+Approve claim?

I suppose the zero value invoice will not be made in pricing manager for this? Is that the only diff or any other?

2. FOR A PAID PACKAGE: If a client has say 10 listings (branches), and does not want to do 10 claim forms + payment gateway transactions to claim these, and wants a single invoice (which I can make offline, and collect payment by check/bank transfer), then from admin can I set similarly the OWNER/EXPIRE DATE and will then all the behaviour be the same as if it had been done thru pricing manager+payment gateway?

3. Similarly, as above, if a NEW customer wants to add 10 branches and does not want to go thru PG 10 times, then can we just add from admin, and invoice+pay offline, and other behaviour will be the same?

Thanks very much,
Vivek
