Shopify Plus Inventory Management

You Have Outgrown Your Tools

There is a specific moment in a Shopify store's growth where the built-in tools stop being enough. Maybe you crossed 500 SKUs. Maybe you added a second warehouse. Maybe you are doing $2M/year and still using Stocky for purchase orders while manually tracking reorder points in a Google Sheet.

I know this moment because I lived it. The math does not get harder gradually -- it gets harder all at once, the first time you stock out on a best-seller because your "system" could not see that two locations were both running low simultaneously.

Shopify Plus gives you the platform to scale. It does not give you the inventory intelligence to match.

Where Stocky Falls Short

Stocky ships free with Shopify, and it is fine for basic purchase orders. But here is what it cannot do:

Capability	Stocky	ReplenishRadar
Demand forecasting	No	Yes -- per SKU, per location
Reorder point alerts	No	Yes -- accounts for lead time + safety stock
Multi-channel (Amazon)	No	Yes -- unified view
Forecast accuracy tracking	No	Yes -- measures prediction vs actual
Transfer suggestions	No	Yes -- warehouse to FBA
Sync frequency	Manual/daily	5-30 min depending on plan

If you are on Shopify Plus, you are probably past the point where "basic purchase orders" covers it. You need to know what to order, how much, and when -- before you run out, not after.

The High-Volume Problem Set

Shopify Plus stores have specific inventory challenges that smaller stores do not:

SKU proliferation. You might have 200 products but 3,000 variants once you factor in sizes, colors, and bundles. Each variant needs its own forecast. Each variant has its own velocity. Manually reviewing 3,000 SKUs to decide what to reorder is not a weekly task anyone actually does -- so things slip through.

Multiple locations. A warehouse in Ohio, a 3PL in California, a retail store in New York. Shopify tracks inventory at each location, but it does not tell you that Ohio has 90 days of supply while California has 8. That imbalance means you are overstocked in one place and about to stock out in another.

Complex supplier relationships. You are probably ordering from 5-15 suppliers with different lead times, MOQs, and payment terms. Your reorder point for a product with a 14-day lead time from a domestic supplier is completely different from one with a 60-day lead time from overseas. Stocky does not factor this in. ReplenishRadar does.

Seasonal complexity. Your Q4 is 3x your Q2. If your reorder point is based on average velocity, you are either overstocked for 9 months or understocked for 3. The forecast needs to account for seasonality, and the reorder point needs to shift with it.

What the Growth Tier Gives You

Most Shopify Plus stores land on our Growth plan. Here is why:

20,000 SKUs covers even aggressive variant structures. 15-minute sync keeps your data fresh enough for high-volume operations without the cost of Scale. And you get features that matter at this stage:

Triage Mode flags SKUs that need attention -- data quality issues, missing costs, variants without enough history to forecast. On a 5,000 SKU catalog, you might have 200 items that need cleanup. Triage surfaces them instead of making you hunt.

Vendor workflows let you organize purchase orders by supplier, apply lead times per vendor, and track which suppliers are actually delivering on time. After 90 days, you will have data on whether your "3-week supplier" is actually a 4-week supplier. Your reorder points adjust accordingly.

FBA Intelligence applies if you also sell on Amazon -- it tracks your FBA inventory and suggests transfers from your warehouse. Most Shopify Plus brands doing $3M+ are on Amazon too.

The Practical Difference

Here is what changes after you connect ReplenishRadar to your Shopify Plus store:

Week 1, you connect and import. We pull your catalog, inventory, and up to 2 years of order history. SKUs match automatically by SKU code.

Week 2, forecasts generate. Every variant gets a demand prediction based on its own sales pattern. You see which products are trending up, which are flat, which are declining.

Week 3 onward, the system works for you. Reorder alerts fire based on actual lead times and safety stock. Instead of reviewing thousands of SKUs to decide what to order, you review the 30-50 items that need action this week.

I have talked to Shopify Plus merchants who spent 8-10 hours a week on reorder decisions. After 30 days on ReplenishRadar, most get it under 2 hours. The math did not change. The tool doing the math changed.
