Benefit

Integrate via 50+ SDKs and APIs without replacing systems of record. PubNub becomes the event backbone connecting storefronts, back office, and fulfillment partners.

Batch Inventory Sync Is Quietly Taxing Your P&L

Oversells trigger cancellations, refunds, and negative reviews that damage marketplace rankings and brand trust.

Ops teams drown in reconciliation work as SKUs and channels grow, while engineering defers high-impact features.

Without a real-time layer, every new warehouse or channel multiplies complexity and risk instead of growing profitable revenue.

Understand the tradeoffs between building your own real-time layer and choosing a proven, managed platform.

Frequently Asked Questions

How does PubNub improve ecommerce inventory management?

PubNub acts as a real-time event layer between your inventory system and every channel. When stock changes, we deliver that update to all subscribed systems in under 100ms, so product pages, carts, warehouse tools, and marketplace connectors all operate on the same current quantity. This dramatically reduces overselling risk and manual reconciliation work.

Do we need to replace our existing OMS or WMS?

No. PubNub does not replace your order or warehouse management systems. It connects them. Your OMS/WMS remains the system of record, while PubNub distributes its inventory change events to storefronts, mobile apps, marketplaces, and internal tools in real time.

What does integration look like for our engineering team?

Developers integrate via PubNub SDKs for JavaScript, iOS, Android, and common backend languages. Your inventory or OMS service publishes stock change events to channels; subscribing services and frontends receive updates instantly. Edge functions can apply business rules—such as validation, filtering, or enrichment—without deploying new servers.

How is security and access control managed?

All data is encrypted in transit, and optional message-level encryption is available. PubNub's access control system lets you issue short-lived tokens with fine-grained permissions, so only authorized services and clients can publish or subscribe to specific inventory channels.

How do we buy PubNub and complete security review?

Most customers follow a simple path: 1) run a limited-scope pilot to validate architecture and business impact; 2) request our security and compliance documentation to support InfoSec review; 3) finalize commercial terms aligned to forecastable drivers like active users and message volume; 4) expand to additional teams and use cases once value is proven.
