Real numbers from ZonPrep sellers

Amazon reporting mechanisms make it difficult to identify your inbound times, spend, placement fees, and your spend in partner carrier program freight. But all of these metrics are necessary to fully understand your FBA supply chain performance. We created an easy way to understand your FBA metrics, and share some of the results below.

Frequently Asked Questions

What does a ZonPrep FBA Opportunity Analysis measure?

We pull a seller's own inbound history to see how long their freight actually took from their dock to receipt at an Amazon fulfillment center, shipping direct. Then we measure the same journey through ZonPrep, from their ship date through prep and consolidation to receipt at Amazon.

Why do your time windows differ?

Most figures here will be a 30-day trailing average. Some are pulled over 365 days, where a longer window gives a clearer picture of an account with seasonal or uneven volume. The window is shown on every card.

Who are those brands?

These are our clients' operating numbers, which are not for us to publish with their names attached. Where a brand agrees to go on the record, the full story runs as a case study instead.
