Warehouse & Multi-Location Inventory

The Spreadsheet You Cannot Kill

Every multi-location seller I have talked to has one. The spreadsheet that tracks what is where. It has 6 tabs, 14 conditional formatting rules, and at least one VLOOKUP that nobody understands anymore. It was supposed to be temporary.

That spreadsheet exists because no single system shows you the full picture. Shopify knows what is in your Shopify locations. Amazon knows what is in FBA. Your 3PL sends a CSV on Tuesdays. Your warehouse manager texts you when something looks low. And you, the person who actually needs to make ordering decisions, spend 2 hours stitching it all together before you can answer a simple question: how much do we actually have?

We built ReplenishRadar to kill that spreadsheet.

What "Multi-Location" Actually Means

Most inventory tools let you add locations as labels. That is not the same thing. A label tells you where something is. A real multi-location system tells you where everything is, what is moving between locations, what is about to run out at each one, and what you should do about it.

Here is what ReplenishRadar tracks per SKU, per location, updated on every sync:

Data Point	What It Tells You
On-hand quantity	What is physically at each location right now
Available quantity	On-hand minus committed (allocated to orders)
In-transit inbound	Units from open POs headed to this location
In-transit transfers	Units moving between your locations
Days of supply	How long current stock lasts at this location's sell rate
Inventory position	On-hand + in-transit, the number you actually reorder against

That last row matters. If you have 200 units in your warehouse and 500 units on a PO arriving in 8 days, your inventory position is 700. Most sellers reorder based on the 200 they can see on the shelf and end up double-ordering. The position calculation prevents that.

Transfers: The Part Everyone Gets Wrong

Moving inventory between your own locations sounds simple. It is not. I have watched sellers lose track of $50,000 in in-transit inventory because "we shipped it last week, it is probably there by now."

ReplenishRadar handles transfers as a full workflow, not a note in a spreadsheet:

Suggestions. The system looks at sell-through rates and stock levels at each location. If your Ohio warehouse has 400 units and your California 3PL has 12 days of supply left, it suggests a transfer. You do not have to notice the imbalance yourself.

Ship, receive, confirm. Every transfer moves through stages. You ship from the origin, receive at the destination, and confirm the quantities match. If 500 units shipped but only 480 arrived, that discrepancy is recorded instead of silently disappearing.

FBA manifests. If the destination is Amazon FBA, ReplenishRadar generates the inbound shipment through Amazon's SP-API. No copy-pasting quantities into Seller Central. The manifest exports directly. Read more about this in our FBA inbound tracking feature overview.

The Transfers tab shows KPIs at a glance: open transfers, pending suggestions, in-transit units, overdue arrivals. If something should have arrived 3 days ago, you see it without digging.

One Dashboard, Every Location

When you log into ReplenishRadar, the global context bar lets you filter by store or view everything at once. Running two Shopify stores and an Amazon account? Switch between them or see the combined picture.

This is not a cosmetic feature. I have worked with sellers running a DTC Shopify store and an Amazon storefront who had no idea that their combined inventory position on a best-seller was 45 days while they thought each channel had "enough." They were counting the same warehouse stock twice in their heads. The unified inventory view fixes that by showing exactly where every unit sits.

For sellers managing multiple Shopify stores, ReplenishRadar pulls locations from each store independently. Store A might have a warehouse and two retail locations. Store B might ship from a single 3PL. Every location appears in the same inventory grid.

The Dollar Cost of Bad Location Data

Here is a quick example. Say you sell a product at 40 units/week total across two locations. Location A does 25/week, Location B does 15/week. Your supplier lead time is 4 weeks.

If you reorder based on the combined number (40/week x 4 weeks = 160 units), you might send 80 to each location. That leaves Location A with roughly 3 weeks of supply and Location B with over 5 weeks. Location A stocks out. Location B ties up cash in excess inventory.

The per-location view changes the math:

• Location A needs: 25/week x 4 weeks = 100 units reorder point
• Location B needs: 15/week x 4 weeks = 60 units reorder point

That is a 20-unit difference in allocation. At a $30 cost per unit, the wrong split costs you either a stockout worth $3,000+ in lost sales or $600 in unnecessary carrying cost. Multiply by 200 SKUs and you are talking about real money.

ReplenishRadar runs the demand forecast per SKU per location. The reorder points reflect where the product actually sells, not an average across your business.

Location Management

You can create, edit, and deactivate locations as your operations change. Opened a new warehouse? Add it. Closed a retail store? Deactivate it so historical data stays intact but it stops appearing in active views.

Locations sync automatically from connected stores. When you add a new location in Shopify Admin, it shows up in ReplenishRadar on the next sync cycle. No manual setup required.

Pricing

All plans include unlimited locations. The limits that matter are stores and SKUs.

	Standard	Growth	Scale
Monthly price	$99	$199	$499
Connected stores	2	5	10
Active SKUs	2,000	20,000	50,000
Locations	Unlimited	Unlimited	Unlimited
Sync interval	30 min	15 min	5 min
Transfer workflow	Yes	Yes	Yes
FBA manifest export	Yes	Yes	Yes

Most multi-location sellers start on Growth. Two stores and a few thousand SKUs outgrows Standard quickly, and the 15-minute sync matters when you are managing transfers between locations. If you are running 5+ stores or need near-real-time data, Scale is where you land.

Every plan includes a 14-day free trial. Connect your stores, see your inventory across every location, and decide if the spreadsheet is finally dead.
