FBM Fulfillment Performance Report

Received my first fulfillment report as a new FBM seller. Looking for some guidance.

The good news is that nothing is showing up late. The bad news is that everything is very early.

1) Handling Time: 1.8 days early. This I can easily control. My understanding is that 1 day early or less is ok. Is that correct?

2) Transit Time: 2.2 days early. My shipping template is set up using the Free Economy option and I ship USPS ground advantage. The only transit time options are 3-5 or 4-8 days so I can’t shorten the transit time to match my performance. Am I better off using the Standard Shipping option with the cost set to $0? It says that the transit time is “Managed by Amazon” with this option.

3) OTD: 95%. No issues here.

Thanks for the input.
