The Reality

Growth exposes Supply Chains that were never built for it.

01
You’re scaling. Your Supply Chain wasn’t designed for this.
Stockouts. Supplier chaos. No planning logic.
Your team reacts instead of plans.
02
You know something’s off. You just can’t name it.
Hiring a full-time Head of Supply Chain is slow and expensive.
You need the problem fixed.
03
Consultants give you slides.
I build what works.
Diagnose. Structure. Stabilize. Hand it over.

How It Works

Three phases.
One Supply Chain that lasts.

01
Diagnostic
I show you what’s off.
6 to 8 weeks / Fixed fee

I map your Supply Chain with your team. I talk to everyone involved — procurement, finance, operations, logistics. I find what’s actually happening versus what’s supposed to happen. You get a complete current-state picture, a gap analysis and a prioritized 12–36 month roadmap that we will implement in Phase 02.

  • North Star and Target State
  • As-Is Process Map
  • Gap Analysis
  • OKR Roadmap
02
Structure
I build what works.
6 to 8 months / Monthly retainer

I take ownership of the roadmap and drive implementation. I don’t only advise from the side — I sit inside the business and move things forward. Target Operating Model. S&OP cadence. KPI framework. Supplier and 3PL decisions. Execution and Leadership, not advice.

  • Target Operating Model
  • S&OP System
  • ERP and 3PL Steering
  • KPI Dashboard and Cadence
03
Stabilize
I make sure it lasts.
Ongoing / Light retainer

Your system runs. I make sure it stays that way. Monthly reviews. Early issue detection. Strategic sparring when needed. The founder stays out of operational firefighting — permanently.

  • Monthly Review
  • KPI Monitoring
  • Escalation Support
About

Not a consultant.
An operator.

I am Marco Koehler.
I have run Supply Chains under real growth.

I push for above-average performance.
So your KPIs outperform the benchmark.
This is where most brands operate.
It’s not where you scale.
Out-of-Stock Rate
8–12%Typical for D2C brands
0%100%
The middle of average is still 10%. That is lost revenue. Every day.
OTIF — On-Time-In-Full
70–85%Typical supplier reliability
0%100%
This is considered "reliable". It means delays are part of your system.
Inventory Coverage
2–4 monthsWhat most brands carry
0 days365 days
This is where cash gets stuck. Or stock is still missing.

Supply Chain Knowledge
Fundamentals

What is Supply Chain, really?

Most people think Supply Chain is logistics. It’s not. Logistics moves boxes. Supply Chain decides which boxes exist, where they sit, and what they cost you when demand shifts. Get it right and growth scales. Get it wrong and you’re out of stock on bestsellers while sitting on dead inventory.

AI & Technology

How AI is changing Supply Chain

The honest answer: less than the headlines suggest, more than most operators realize. AI won’t replace your planner. But it’s already changing how forecasts get built and how exceptions get handled. The brands pulling ahead fixed their data first, then layered AI on top. Sequence matters.

Hiring & Consulting

When does it make sense to hire a Supply Chain consultant?

Not when things are calm. Not when you’re under €5M. The honest trigger: you’re growing fast, your spreadsheets are breaking, and nobody owns the full picture end-to-end. If you’re scaling past €15M revenue without a system underneath, that’s the moment. Earlier is too early. Later is expensive.
