Glasshouse is the real-time operations dashboard that comes with every Nice Fulfillment partnership: live inventory counts, sell-through, carrier cost, and landed cost per order across the Charleston, SC and Salt Lake City, UT hubs, in one login, with no overnight batch exports and no waiting on a Slack message back from your account manager.
Most ecommerce brands find out something is wrong the same way: a customer emails asking where their order went, or a Monday morning spreadsheet pull shows a number that stopped being true three days earlier. The warehouse already knows. You just haven't heard yet, because most 3PL portals were built for floor supervisors, not for the founder or finance lead trying to run a Q4 plan on live numbers.
Real-time visibility is what separates a 3PL built to scale you from one built to just move boxes.
Visibility is where the gap between 3PLs shows up first. What actually separates a 3PL built to scale ecommerce brands from one built for transactional picking and packing is throughput, and whether you can see throughput in real time. The warehouse already knows the inventory position. The question is whether that knowledge reaches you the same day or the Monday after.
The scale of what’s moving through ecommerce right now makes that lag harder to absorb. The National Retail Federation expects 2026 winter holiday sales to climb 4.2% over 2025, reaching a range of $997.3 billion to $1.013 trillion. At that volume, a one-day gap between the warehouse floor and your dashboard isn’t a rounding error anymore. It’s backordered gifts, oversold bestsellers, and a support inbox full of people asking where their package is.
We’ve written before about what separates a 3PL built for ecommerce from one built for enterprise freight in our guide on how to choose a 3PL. Glasshouse is Nice Fulfillment's answer to that difference: one login, built by people who ran their own ecommerce warehouses before they ran anyone else's.
