The mandate

Promise next-day delivery on 95% of orders without adding warehouse capacity, or lose two anchor retail accounts.

Why it mattered

  • 2 contracts worth 38% of revenue were up for renewal.
  • SLA penalties hit $90K in the prior quarter.
  • Peak season was 11 weeks away.
The Challenge

A nightly batch pipeline that couldn't see today.

Before Lumen
6–14h
Data latency

Inventory and order state refreshed once per night. Pickers worked from numbers that were already wrong by morning.

23%
Orders missing next-day SLA

Nearly one in four shipments slipped, triggering penalties and angry escalations from two anchor accounts.

Disconnected systems

WMS, carrier APIs, and store feeds stitched together by fragile cron jobs and three overnight engineers.

The breaking point. During a Black Friday dry run, a single delayed feed cascaded into 4,100 mis-routed orders before anyone noticed at 6 a.m. The CEO called it "flying the warehouse with the lights off."

Before → After

From firefighting to flow.

Before Q4 2025
  • Nightly batch, stale by morning
  • Ops reacting to yesterday's data
  • 3 engineers babysitting cron jobs
  • SLA breaches found after the fact
  • Peak season meant all-nighters
After Q1 2026
  • Streaming events, <2s end to end
  • Ops act on live signals as they happen
  • Pipelines self-heal, on-call quiet
  • SLA risk flagged before the breach
  • Peak handled without extra hires
The Solution

One streaming control plane for the whole network.

Lumen sits between every source system and the warehouse floor, turning fragmented feeds into a single live view operators actually trust.

Architecture
01

Unified event stream

Every system change becomes a typed event in under 2 seconds. No more nightly reconciliation.

02

Predictive SLA guard

Models flag at-risk orders the moment they trend late, with a one-click reroute to the fastest path.

03

Self-healing pipelines

Failed feeds retry, backfill, and page only when a human is truly needed. On-call volume dropped 84%.

Live in week three. Network-wide by day 90.

Financial Impact

Where the $4.2M came from.

Annualized, validated by Northwind finance
Avoided SLA penalties

$1.9M — breach fees eliminated across both anchor contracts.

Labor reallocation

$1.1M — overnight engineering hours redirected to revenue work.

Retained revenue

$1.2M — churn risk on renewed accounts, now secured.

"We stopped flying the warehouse with the lights off. Lumen gave us a live picture of the entire network, and within a quarter our two biggest customers renewed without a single tense call. It paid for itself before the contract ink was dry."

Beyond The Numbers

The results that don't show up on a dashboard.

No more 3 a.m. pages

The overnight on-call rotation went from 31 pages a week to 5. Two engineers moved off nights entirely.

Trust restored

Anchor customers moved from weekly escalation calls to a quarterly business review. The relationship flipped.

Peak, without panic

Northwind handled its highest-volume week ever with the same headcount, and zero unplanned overtime.
