# Can I Change Quantities on an Amazon Shipment Plan I Have Already Generated?

If you have already approved [a shipment plan](https://www.flexport.com/help/amazon-us-shipment-plan/), Amazon FBA will only allow the quantity of each Amazon SKU to be edited up to 5%, or up to 6 units, above or below the original amount without incurring fees.

If you need to add more units, you will need to duplicate the shipment or create a new shipment. 

You cannot add additional Amazon SKUs. 

For more information see [Amazon’s Help Center.](https://sellercentral.amazon.com/gp/help/external/201021880?ref=efph_201021880_cont_201021870&language=en-US)
