Operational intelligence for your fulfillment flow

FillSpeed surfaces operational bottlenecks, slowdowns, and flow performance issues in real time — giving your Shopify store the visibility to fulfill faster, stay consistent, and handle demand with confidence.

It's all about fulfillment flow

Flow drives fulfillment performance. Every order follows a path through your operation, and the shape of that flow determines how fast you can fulfill. When flow is smooth, work moves continuously. When it breaks, delays ripple outward — creating backlogs, idle time, and unpredictable slowdowns.

Most tools show you what happened. FillSpeed shows you why it happened by revealing the underlying flow patterns that shape performance. With clarity into where work is waiting, blocked, or building up, you can fix issues at their source instead of reacting after the fact.

This is the foundation of operational intelligence: understanding your fulfillment as a living flow system and knowing exactly where to intervene to keep it moving.

How FillSpeed Works

FillSpeed monitors each step of your fulfillment flow, measures timing and variability, and surfaces KPIs and alerts in real time.

FillSpeed reads your fulfillment flow. It maps the same steps every Shopify order already moves through — but adds timing, flow analysis, and performance monitoring on top of them. As orders progress from creation to delivery, FillSpeed measures how long work waits at each stage, detects where flow slows or stalls, and identifies the patterns that lead to bottlenecks.

By continuously tracking the movement of orders through your operation, FillSpeed builds a real‑time picture of your fulfillment flow: where work is smooth, where it’s backing up, and where variability is creating hidden delays. This is how Flow Intelligence works — by understanding the physics of how work moves so you can intervene before slowdowns spread.

What FillSpeed Does For Your Ops

FillSpeed gives you Flow Tools for real operational work. It doesn’t just show you data — it interprets how work moves through your fulfillment process and gives you the tools to act on it. From tracking delays to detecting bottlenecks and surfacing real‑time performance signals, FillSpeed turns your flow into something you can monitor, understand, and improve.

The FillSpeed Live Heatmap gives you a real-time, stage-by-stage view of how each order is progressing through the fulfillment pipeline. It helps operators instantly spot delays, bottlenecks, and performance trends using a combination of elapsed time, CAR values, and color indicators.

Detect Delays with Heatmap

The FillSpeed Workload Scatter Chart shows how fast your fulfillment operation is moving for a selected period and fulfillment node.

Detect Bottleneck Patterns

The FillSpeed Cumulative Workflow Chart shows how work is flowing through your fulfillment operation over time. It highlights how many orders are entering, progressing through, and completing each stage, helping you spot buildup, smooth flow, or emerging bottlenecks at a glance.

Detect Flow Patterns

The FillSpeed Cycletime Explorer shows the cycletime details for each stage of the order and contrasts it with the cumulative averages of the corresponding stages.

Track Order Cycletimes

The FillSpeed Insights for Fulfillment KPIs and Activity Metrics shows charts for the following fulfillment KPIs and activity counts for a given time period and fulfillment node.

Track Performance Trends

Detect Delays Early

See where orders are getting stuck — picking, packing, or handoff.
Merchants often don’t know why orders slow down. FillSpeed surfaces the exact step causing delays so you can fix issues before they pile up.

Understand Your Bottlenecks

Identify patterns behind recurring slowdowns. Whether it’s labor capacity, batching behavior, or carrier pickup timing, FillSpeed reveals the root causes behind fulfillment instability.

Monitor Daily Flow Health

Track how smoothly orders move through your workflow. Get a real‑time sense of whether today’s fulfillment is on track, drifting, or at risk — without building dashboards or reports.

Track Order Cycle times

Track cycle times for each of the order stages for all orders 24x7x365. Understand the cumulative averages and trends for pick-pack-ship, pre-transit, in-transit, out-for-delivery and delivery stages.

Track Fulfillment KPIs

Automatically track key fulfillment KPIS: Fulfilled-on-time (FOT), Delivered-on-time (DOT), Delivered-in-full, (DIF) and On-time-In-Full (OTIF).

Track Performance Trends

Track how your fulfillment process cycle time averages, KPIs and activity metrics vary over time to inform what aspects of your operation need improvements.
