OOh my goodness thank you So much! I was actually wondering about this Same exact thing. Also as for accepting the msp things where we electronically sign to accept. Do we go ahead and do that in advance for all the shops or companies that are providing us with the shops?

You only need to do it once for each Mystery Shopping Provider - it needs to be done in order for you to be able to request/self-assign their shops, and receive payment for doing them.
