Payments go out on a weekly net 7 schedule. This means that once an invoice is generated, you will be paid that invoice 7 days later.
Invoices are generated weekly, on Monday, for your earnings from Monday to Sunday.
For example, on Monday May 14th you will receive an invoice from the previous week of earnings (Monday May 7th - Sunday May 13th). This invoice will be paid 7 days later on the following Monday May 21st.
There is a $50 threshold to have an invoice created. Invoices will only be generated on Monday if you have earned over $50 in the previous pay period.
