Your stock. All your sites.
In real time.
Warehouses, stores, suppliers, in transit: Spacefill consolidates every stock position
from all your sites and systems into a single view, continuously synced.
No stockouts, no overselling.
The real cost of fragmented inventory
When your stock is scattered, every order is a gamble.
As soon as you sell on more than one channel, run more than one store or warehouse, or work with logistics partners, your inventory visibility fragments. The data lives in different systems. Nobody sees the same number.
Overselling and stockouts
Each channel draws from its own siloed stock pool. A product shows as available on your e-commerce site while the last unit is already being picked for a marketplace order.
Stock split by constraint, not by choice
Your ERP has its version of stock. Your e-commerce platform has another. Each 3PL runs its own WMS. Reconciling them is manual work that costs hours every week and still doesn't produce a reliable number.
No consolidated view of available-to-sell
Your customer service and supply teams make sub-optimal routing decisions, while your merchandising team replenishes the wrong warehouses.
In-transit and supplier stock is invisible
Stock moving between sites, in transit, in receiving, or sitting at a supplier on a confirmed order or quote: none of it shows up in real time. You can't promise delivery on stock arriving within 48 hours, or make the right allocation decisions.
What Spacefill changes
One unified, real-time inventory view. Every site. Every system.
Aggregate inventory from all your WMS, ERP, stores, transport and suppliers into a single continuously synced layer. This is the stock truth your orchestration engine, your delivery promise and your replenishment can finally rely on.
Unified stock across every node
Warehouses, stores, suppliers, consignment stock, in-transit stock, all visible in one place, down to SKU and location level.
Real-time sync, not an overnight batch
Stock positions update in near real time from every connected WMS, ERP and POS. No more decisions made on yesterday's data.
Accurate available-to-promise
Spacefill calculates real ATP per site, factoring in reservations, inbound deliveries and replenishments, and incoming supplier orders. Promise what you can actually deliver.
Automatic alerts, no manual monitoring
Low stock thresholds, imminent stockouts, abnormal turnover rates: detect and notify without watching your dashboards all day.
How it works
Five capabilities that change what you can do.
Unified inventory layer
All your stock positions, in one place.
Spacefill connects to your ERP, your store POS systems and your 3PLs' WMS. It aggregates every position (physical stock, reserved units, in transit, supplier POs) into a single normalized view.
50+ WMS natively connected.
Real-time synchronization
No more decisions based on yesterday's numbers.
Sync latency under 30 seconds for webhook-compatible WMS. Automatic conflict resolution when two sources report different quantities. Full traceability.
−94% picking errors and stock discrepancies observed across Spacefill customers.
Promesse de livraison
Tell your customer exactly when they'll receive their order.
At checkout, calculate in real time which node can ship, at what cost, and by when. Show a precise date, not "3 to 5 business days".
+12% conversion on average.
Inventory rules and allocation
Allocate stock the way your business actually needs.
Ring-fence inventory for your B2B customers, protect safety stock, prioritize specific channels. Configure allocation logic without touching the WMS.
+18% inventory turnover.
Middleware and normalization
Connect every source. Spacefill normalizes the data.
Pre-built connectors: REST API, webhooks, EDI, SFTP. Automatic product master data mapping. Discrepancy reconciliation.
−70% time spent reconciling stock.
Smart alerts
Your inventory is telling you something. You just have to hear it
Imminent stockout
ATP stock drops below the defined minimum threshold. An alert fires automatically before the stockout actually happens, identifying the most exposed channel.
Action: draft replenishment PO + Slack notification
Abnormally low turnover
A SKU sits still at one site while it sells well elsewhere. Spacefill detects the gap and flags a potential localized overstock or a channel availability issue.
Action: variance report + inter-site transfer suggestion
Stock imbalance across sites
One warehouse is saturated while another is close to a stockout on the same SKU. Alert with a rebalancing recommendation and an estimated transfer cost.
Action: inter-site rebalancing recommendation
Supplier receipt confirmed
A supplier PO moves to "confirmed" status. Spacefill factors the expected stock into future ATP and notifies sales teams, who can start committing to customers right away.
Action: future ATP update + sales team notification

Before / After
What actually changes when inventory goes real time.
Siloed stock data
Stock data lives in 4 different systems. Reconciliation is a weekly manual job.
Unified inventory layer
One single unified inventory layer. Updated in near real time from every source.
E-commerce overselling
Your storefront shows "in stock" on items that are reserved or already out at the 3PL.
Reliable ATP, no more overselling
ATP is calculated from real stock minus reservations. Overselling stops.
Vague delivery promise
The checkout promise is generic ("3 to 5 business days") and conversion suffers.
Precise date at checkout
Checkout shows the exact delivery date. Conversion rises by an average of 12%.

Frequently Asked Questions about our IMS
Everything you need to know before getting started
An IMS is inventory management software that enables real-time tracking of inventory levels, automates replenishment alerts, and optimizes inventory turnover. It connects to Warehouse Management Systems (WMS) and e-commerce platforms to provide a unified view of all your inventory.
A WMS (Warehouse Management System) manages physical operations inside a warehouse (receiving, storage, picking, packing).
An IMS operates at a more strategic level, overseeing inventory across multiple warehouses and logistics providers.
Spacefill acts as a middleware, connecting your ERP to your 3PLs’ WMS to deliver a consolidated inventory view.
Spacefill offers pre-built connectors with leading WMS solutions on the market (Akanea, Stock-iT, Infolog, etc.).
Implementation is fast (a few weeks) and requires no heavy development on your side.
For WMS not yet connected, we build custom integrations.
Spacefill is designed for brands and retailers with annual revenue between €5M and €100M that outsource their logistics.
