Your spreadsheet inventory system worked at 20 orders a day. Now you're doing 200, and everything is breaking.
"I'm running a Shopify store that went from like 50 orders a day to 300+ in the last four months. I'm constantly overselling things or running out of stock when I thought we had plenty."

This is the moment you need a Warehouse Management System (WMS). But with dozens of options ranging from $0 to $10,000/month, how do you choose? This guide breaks down the best WMS options for ecommerce brands at different stages.
What Is a WMS and When Do You Need One?
A Warehouse Management System (WMS) manages your inventory, picking, packing, and shipping operations. It's the layer between your sales channels and your physical warehouse.
Signs you need a WMS:
- Overselling products regularly
- Picking errors increasing (wrong items shipped)
- Can't track inventory across multiple locations
- Spending hours on manual inventory counts
- Multi-location sync is a nightmare
"What made you realize you needed something more robust? For us it was shipping the wrong item three times in one week and losing a customer over it."

Best WMS by Business Stage
Stage 1: 50-200 Orders/Day
Recommended: ShipStation or ShipHero
At this stage, you need basic inventory sync and streamlined shipping. You don't need a full WMS yet.
- ShipStation — Multi-carrier rate shopping, batch labels, basic inventory. $9-159/month.
- ShipHero — Better inventory features, barcode scanning, pick lists. Starts at $499/month.
- Ordoro — Good for dropshipping + inventory combo. Starts at $59/month.
Stage 2: 200-500 Orders/Day
Recommended: SkuVault or Cin7
Now you need barcode scanning, wave picking, and real-time inventory updates. Manual processes break at this scale.
Stage 3: 500+ Orders/Day
Recommended: Deposco or Extensiv
Enterprise-level needs: multi-warehouse, 3PL management, advanced analytics, custom workflows.
"We went with Deposco after trying a couple other options, the multi location sync was what really helped us because before that we were manually reconciling everything between our warehouse and 3PL like twice a day."

- Deposco — Cloud-native, multi-location, built for scale. Custom pricing.
- Extensiv (formerly Skubana) — Full operations platform, 3PL management. Custom pricing.
- NetSuite WMS — If you're already on NetSuite ERP. Add-on pricing.
When to Use a 3PL Instead
Sometimes the answer isn't a WMS—it's outsourcing fulfillment entirely.
"3PL, and you should've done it yesterday. You're much more valuable focusing on more sales than doing logistics. That's a cost center, not a growth driver."

Consider a 3PL if:
- You're spending 20+ hours/week on fulfillment
- Your garage/basement is at capacity
- Shipping costs are killing you (3PLs get volume discounts)
- You'd rather focus on marketing and product than logistics
Top 3PLs for Shopify: ShipBob, Deliverr (now Flexport), Red Stag Fulfillment.

Frequently Asked Questions
What made you realize you needed something more robust?
Most brands realize they need a WMS when overselling becomes regular, picking errors increase, or they expand to multiple locations. If you're manually reconciling inventory more than once a day, it's time.
How do you handle multi-location inventory sync?
Modern WMS solutions like Deposco and Cin7 sync inventory in real-time across locations. The key is having all locations connected to the same system rather than separate spreadsheets or tools.
What works for 300+ orders a day?
At 300+ orders/day, look at Deposco, SkuVault, or Extensiv. You need wave picking, barcode scanning, and real-time updates. Manual processes will create daily fires at this volume.
