I'm a little nervous too-----SCS has never been very quick about paying, but anyone can see that this is a one-man show and maybe a part-time gig besides. Other things can quickly get in the way. If you never interface personally with your shoppers, it is easy not to pay them and let them write it off as a business loss. I was thinking about doing a restaurant shop today, but I haven't been paid for the two shops I did in November or the one I did in December yet and it makes me nervous. I wouldn't go and eat in these restaurants if it were not for the mystery shopping. Usually when I ask about payment time-lines, I get a response. I haven't gotten one despite a couple of attempts.
Personally, I think that if you are a reliable payer, you will attract a better shopper. Also----if you state CLEARLY your payment timeline, then the shopper has less to worry about. Having to remind someone that they owe you money is simply not right. I will be calling though. I don't want another NSS type loss that I have to absorb.
