A clause found in some MSP/RPO agreements through which the intermediary (MSP or RPO) has no obligation to pay sub-vendors (staffing suppliers) unless and until the end-user (buyer) settles its own invoices. Pay When Paid Clauses are popular with buyers as it enables them to simplify their invoicing procedures and provides them with “one throat to choke” while the intermediary also gains – primarily from cash management opportunities. However, the concept is much less popular among sub-vendors, which often have no knowledge of whether the end-user has made a payment and is usually discouraged or prevented from having a direct dialogue with the end-user. Sub-vendors also suffer from this arrangement as it limits their ability to factor invoices and thereby finance their business.
