What is an OISR and why have I received it?
What it is:
If you have received an Open Invoice Status Report (OISR), then you can expect to receive the funds listed on the report. The OISR is a list of receivables by customer and represents credits/refunds which are owed to you. Approximately 7 days after receiving the OISR, you will receive a Remittance Advice which details the invoices for payments received.
What it isn’t:
The OISR is not an invoice of charges. Responsibility for payment falls upon the customers listed on the report.
