I began making a chart of all the companies I do shops for and when they pay and in what form. I have collected this information from each comanies own website. I have a few I cannot find info for but here is what I have( some may have multiple forms of payment but I wrote which I use from the company):
CRI- direct deposit- Submit before Monday to be paid following Friday
Secret Shopper- Check- 19th of following month
ICCDS- Check- Last week of following month
BARE- Direct Deposit- 15th- 20th of following month
Amusement Advantage- Paypal- 14 to 21 days after shop completion
Reality Based Group- Paypal- Unknown
Market Force- Direct Deposit- before 20th of following month
In Touch- Direct deposit- ~ 4 weeks after shop date, payments issued bi-weekly
GFK- Paypal- 2 to 3 weeks after shop date
J.M. Ridgeway- Prior to end of following month
KSS- does not pay through their group. Providers pay directly
Second to None- Direct deposit- unknown
Those are the ones I have found that I use.
