Fixed contractors are paid the same amount of money each month. For fixed contractors, Oyster will auto generate the invoice each month. Contractors do not have to generate their own invoices.
Pay As You Go (PAYG) contractors get paid a defined rate per defined unit. This could be
-Fixed rate either hourly, daily or weekly
-Pay per task
PAYG contractors have access to the Oyster's invoicing engine. They can easily create new invoices which are then submitted for approval. PAYG contractors must generate their own invoices.
All invoices are stored on Oyster.
