If I'm not mistaken, and I'm 99.9% sure I'm not, 60 days from last day of the month the shop was performed in has been their terms since I started shopping in July, 2013. There was some discussion about that in the thread when HS Brands bought MCP and @Lorri Kern KSS "corrected me" that this was no longer the case. So apparently they have returned to this schedule?
Service Sleuth is really more than 2 months! after the last day of the month in which the shop was performed. Two people said above that it is a shorter time frame. From their site:
Compensation for contracted services are submitted to PayPal approximately 60 days after the last day of the month in which the shop was completed. Please note that it then takes PayPal up to 5 business days to process this transaction and clear the money for disbursement.
So if you do a shop June 1 you'll get paid in the first week of September. And if you don't do a glowing report you won't get paid at all.
