In comparison...this is so easy to do also. It may not make the $$$ of a big PL deal...but it will be steady & time/cost efficient sales. Also, SB got an office real close to the ad campaign company...Working Media...so it must be a good working relationship with lots of campaigns slated for the future.
And like you stated...no collections needed...the $ goes right into the operational cash flow...so nothing added to the AR.
