Sound familiar?

  • Spending 4-5 hours daily in ShipStation making the same decisions over and over
  • Manually picking boxes for every order because ShipStation's automation can't handle it
  • Building hacky scripts to check weather forecasts for heat-sensitive shipments
  • Editing PDFs by hand because retailer packing slip requirements are so specific
  • Duct-taping together APIs and spreadsheets just to survive the workload

I spent 4 years processing 1,000-2,000 orders daily. Built every workaround in the book. Eventually realized a proper tool could do all of this—and save thousands per month in shipping costs and labor.

The ShipStation gaps that cost you time and money

4-5 hours daily on shipping decisions

Manual verification of box dimensions, rate shopping for every order, organizing batches by carrier and service type.

Automations ShipStation can't do

Weather-based shipping rules, cross-platform requirements, retailer-specific logic for drop-ship compliance.

Scripts and workarounds everywhere

Local scripts for UPC matching, manual PDF editing for packing slips, platform-specific handling duct-taped together.

FAQ

Common questions from ShipStation power users

Will this mess up my existing ShipStation setup?
Absolutely not. Ship Extension works alongside your existing ShipStation workflow without changing anything. It connects via API to read your orders and suggest optimizations, but never modifies your ShipStation configuration or disrupts your current processes.
How long does it take to see results?
Most customers see immediate time savings on day one. Cost savings from optimized packaging typically appear within the first week. After 30 days, you'll have comprehensive analytics showing exactly how much time and money you're saving.
Do I need to migrate my data or change carriers?
No migration required. Ship Extension works with your existing carriers, boxes, and ShipStation configuration. Simply connect your API credentials and start optimizing immediately. You keep all your negotiated rates and carrier relationships.
What if I process orders in batches or have complex requirements?
Perfect! Ship Extension is designed for high-volume operations with complex needs. Our batch processing handles 1000+ orders per hour, and our rule engine supports sophisticated logic for different customer types, products, destinations, and business requirements.
Is my ShipStation data secure?
Yes. All API connections are encrypted and we never store sensitive customer information. Your ShipStation data remains exactly where it is—we just help you optimize it.
