Pick-Pack Software for Ecommerce Warehouses

Paper pick lists and manual bin counts are fulfillment liabilities at any volume above 50 orders per day. Nexus connects your orders, inventory, and warehouse floor into a single live system — so every pick is confirmed by scan, every shortage fires an alert before it becomes a shipping hold, and your team spends time fulfilling orders, not correcting them.

The Problem

Ecommerce warehouses running on paper lists and manual counting lose hours every day to mispicks, re-counts, and last-minute shipping holds. Errors that seem minor at 30 orders per day become operational crises at 300. The problems are structural — not a people issue, but a systems gap.

Mispicks at scale

Paper pick lists are static. If an order changes after the list is printed, no one knows. Items get picked from the wrong bin, the wrong SKU variant gets packed, and the wrong customer gets the wrong product — with a return request and a customer service conversation as the outcome.

No shortage visibility

Stock-outs are discovered at the packing station — after the picker has walked the warehouse floor. At that point, the order is already delayed and the courier may have already arrived. There's no early-warning system to catch the gap before it becomes a problem.

Disconnected from orders

Warehouse staff work from printed lists while orders in the system continue to change. Cancellations, address corrections, and item substitutions made by the CS team never reach the floor in time. The result is wasted pick time and orders fulfilled for customers who no longer want them.

How Nexus Solves It

Nexus connects your orders, inventory, and warehouse operations so pick lists are always live, stock levels are tracked to the bin location, and shortage alerts fire before the courier arrives. Every pick is confirmed by scan — eliminating the guesswork that drives mispick rates on paper-based workflows.

Barcode scanning

Pickers scan each item before it goes into the box. Nexus matches the scan against the expected SKU in real time. A mismatch is flagged immediately — the picker is prompted to recheck before the order can advance to packing. No more wrong items shipped because a bin was mislabeled.

Live pick lists

Pick lists in Nexus are generated automatically from confirmed orders and update in real time. If an order is cancelled, modified, or placed on hold after the list is generated, the change appears immediately on the picker's screen. No more fulfilling orders that have already changed.

Shortage alerts

Nexus fires shortage alerts the moment available stock drops below what an open order requires — not when a picker reaches an empty bin. Warehouse managers can reallocate, reorder, or communicate with the CS team before the order is already late.

Key Features

Frequently Asked Questions

Does Nexus support multiple warehouse locations?
Yes. Nexus supports multi-warehouse inventory with bin-level tracking. You can see stock across all locations, transfer inventory between warehouses, and assign pick lists to specific warehouse locations. Each location can have its own bin structure, and stock totals are aggregated across all sites for order management purposes.
What happens when a picked item doesn't scan?
If a barcode scan doesn't match the expected SKU for the order line, Nexus flags the mismatch immediately on the picker's screen. The order cannot advance to packing until the issue is resolved — either by rescanning the correct item or by triggering a supervisor override with a reason logged. This catches errors before they ship rather than after a customer complains.
Can Nexus detect ghost stock?
Yes. Ghost stock — items marked as in-stock in the system but with no assigned bin location or physically unverifiable quantity — is one of the most common causes of fulfillment failures. Nexus automatically flags any SKU that has a positive inventory count but lacks a confirmed bin location, and alerts the warehouse manager to investigate before the item is included in a pick list.
Does the pick list update in real time if an order changes?
Yes. Pick lists in Nexus are live documents — not printed snapshots. If an order is cancelled, modified, or placed on hold after the pick list is generated and a picker is already working on it, the change appears on their screen immediately. If the change is significant (item removed, order cancelled), the picker receives a prompt to stop and return the item to stock.
Can I print packing slips and shipping labels directly from Nexus?
Yes. Nexus supports packing slip generation and shipping label printing directly from the fulfillment workflow. Carrier integrations include Bosta, with additional courier support on the roadmap. Labels are generated at the packing station once all scan confirmations are complete, keeping the label tied to a verified order rather than a pre-packed assumption.
