How it works
How the InfiPlex Excelsior integration works
Think of Excelsior as the warehouse execution layer, and InfiPlex as the layer above it that aggregates every sales channel into one order queue and keeps inventory accurate across all of them. InfiPlex sends orders that are ready to fulfill over to Excelsior, your warehouse team picks, packs, and ships them using Excelsior's configured workflow, and InfiPlex pushes the resulting tracking back out to whichever marketplace or storefront the order came from.
