The modern WMS for multi-channel ecommerce brands.
For brands that run their own warehouse and sell across Shopify, WooCommerce, and eBay, with deep SKU and variant catalogues to keep straight.
Orders from Shopify, WooCommerce, and eBay land in one pick queue. Pickers work variant-level lines down to size and colour, shipping labels are created at pack time on your own carrier accounts, and a desktop print client drives every thermal printer on the floor. Connect your stores, set up your warehouse layout, and ship a real order within a workday.
14 days, full access, no credit card required.
Works with your existing stack
From order to dispatch, end to end
OptiWMS covers the full warehouse cycle in one app: receiving, inventory, picking, packing, dispatch, and returns. Everything an operator touches in a day.
Orders land instantly
New orders flow into OptiWMS the moment your store confirms them, via Shopify webhooks out of the box or through the API for other platforms. The pick queue updates within seconds, even when traffic spikes.
Receive stock against POs
Scan supplier barcodes against purchase orders. The receiving page flags shortages, overages, and damage in real time, so they are caught before any stock reaches a bin.
Pick, pack, and label
Wave-based pick queues route operators through the warehouse in the shortest path. Scan-to-confirm at every pick. At the pack station, scanning creates the shipment on your own carrier account and generates the shipping label automatically.
Dispatch syncs back
Once a label is created, the fulfillment pushes back to your store with the tracking number already on the order.
Picking that gets faster as you scale
Wave-based queuing, path optimisation, and stock rotation are part of the base product on every plan.
Serpentine pick paths
Pick queues route operators down each aisle in bin order and back along the next, so the route stays continuous from the first pick to the last and no one doubles back across the floor.
Zone and wave picking
Group orders into waves and assign each picker a zone. Each wave runs as its own batch with its own queue, and adding pickers or zones later is a settings change.
FIFO and FEFO rotation
Pick queues enforce first-in first-out or first-expiry first-out at the item level. The system tells each picker which exact unit to take next, in the order that protects margin and shelf life.
Desktop Print Client
Label printing without the driver nightmare
A small desktop app for macOS and Windows connects your thermal and label printers to OptiWMS. Enroll a workstation once. It runs in the background, picking up print jobs from the warehouse and sending ZPL straight to the printer. The driver setup happens once during enrollment, and label files are handled by the central queue.
One-time device enrollment
Pair a workstation to your warehouse in a couple of clicks. It stays connected through restarts and printer power-cycles.
Direct ZPL to your thermal printers
It detects the printer at enrollment, prints a test label to confirm, and sends raw ZPL at full resolution for every job.
Managed print queues
Jobs queue centrally with retries and visibility. A jammed or offline printer holds its labels until it comes back online.
Built for the operators on the floor
A full warehouse system that a new picker can learn in an afternoon, running on the carrier accounts your team already uses.
Connected to your store
Orders land the moment your store confirms them, and fulfillments push back the instant a label is created. Tracking numbers end up on the order automatically.
Labels at pack time
Create the shipment on your own carrier account and generate the label when you actually pack the box. You stay on the same carrier relationships and the same rates you have today.
Scan-driven operations
Barcode-driven pick, pack, and receive cuts mis-picks and receiving errors. ZPL label queues keep thermal printers fed automatically.
Full inventory audit trail
Every pick, adjustment, and movement is logged with the operator and the timestamp. When a count is off, you can follow the ledger back to the exact scan that broke it.
Multi-warehouse ready
Zones, multi-warehouse inventory, and cross-warehouse order splits are part of the base product. The dashboard treats them as a single view across sites.
Variant-level pick queues
Pick lines are specific: style, size, colour, bin, quantity, in FIFO order. The mobile screen shows the variant name in plain language ("Navy / Medium"), the bin location, and the quantity. Scan to confirm.
Reports
Reports that earn their place
Every report maps to a decision a warehouse manager makes each week: what to reorder, which SKUs are sitting still, which operators are productive, and where stock is going missing.
Never get caught short
Days of Supply, Low Stock, and reorder suggestions surface what to reorder and when, ahead of a bestseller hitting zero.
Free up cash tied in stock
Sell-Through and Inventory Aging surface slow movers and dead stock, so you can move the SKUs that are tying up cash.
Run an accurate, productive floor
Labor Productivity tracks picks and packs per operator; Cycle Count Accuracy and Shrinkage catch variance and loss by zone and by reason.
Hold suppliers to their promises
Supplier Performance scores on-time delivery and receiving accuracy for each supplier individually.
