Our team will look over and reach out to confirm the request, provide timelines and answer any additional questions or issues presented. Please be sure to be as detailed as possible and add any needed documents and/or SKUs to the Files section of the ASN.

Please also wait for confirmation that the work has been completed before pacing an outbound order request.

Use this option when your inventory is already stored in our fba warehouse and the inventory is to be placed back into storage after the prep.

Submit your Request 
The prep services are requested by sending an email to orders@riversourcelogistics.com with details of the workup needed along with each step involved. Detail which SKUs are involved and their quantities, along with providing any required attachments such as FNSKU labels to the email.
