Keeping Inventory Accurate Across Every Channel

Inventory accuracy is the foundation of e-commerce fulfillment. Oversell and you're canceling orders, damaging brand trust, and eating shipping costs. Undersell and you're leaving money on the table.

WarpWare uses a four-layer sync architecture to keep inventory accurate across every connected channel.

Layer 1: Real-Time Webhooks

When a platform supports webhooks for inventory changes, we use them. Shopify product updates, for example, trigger an immediate sync. The moment stock changes on one channel, WarpWare knows about it.

Not every platform supports real-time webhooks for inventory. That's why we don't rely on this layer alone.

Layer 2: Micro-Batch Updates

After every order push to a warehouse, WarpWare immediately decrements inventory on all connected sales channels. This happens within seconds of the order being accepted — not on the next polling cycle.

This is the most critical layer for oversell prevention. The moment an order claims inventory, every channel reflects the change.

Layer 3: Incremental Polling

On a configurable interval (typically 5–15 minutes), each connector polls its source for inventory changes. This catches anything webhooks might have missed — manual adjustments in the warehouse, returns processed outside WarpWare, or receiving new stock.

The polling is incremental. We track the last sync timestamp and only pull changes since then. This keeps API calls low and sync times fast.

Layer 4: Full Reconciliation

Once per day (configurable), WarpWare runs a full reconciliation against the warehouse system. This is the safety net — it catches any drift that accumulated from timing gaps, failed webhooks, or edge cases.

Per-Channel Buffers

On top of the four sync layers, WarpWare supports per-channel inventory buffers. You can hold back 10% of stock from Amazon while making it fully available on Shopify, or reserve units for a wholesale channel.

Buffers are configured per-connection and apply automatically during every sync cycle.

The Result

Most WarpWare customers report zero oversells after implementing the full sync architecture. The combination of real-time decrements, frequent polling, and daily reconciliation covers every scenario we've encountered in production.
