Supply Chain Architect for D2C

I close the Supply Chain
gaps you feel but can’t name.

The ones costing you stockouts, stuck cash, and forecasts that miss.

The Reality

When you scale,
your gaps do, too.

You’re scaling. Your Supply Chain wasn’t designed for this.
Stockouts. Supplier chaos. No planning logic.
Your team reacts instead of plans.
You know something’s off. You just can’t name it.
Nobody inside can. They’re inside it.
Consultants give you slides.
I find the gap, then close it.
Diagnose. Structure. Stabilize. Hand it over.

How It Works

Three phases.
Every gap closed.

Phase 01
Diagnostic
I find the why nobody inside can see.
6 to 8 weeks / Fixed fee

I map your Supply Chain with your team and find what’s actually happening versus what should. You leave with a complete picture and a prioritized roadmap to implement in Phase 02.

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

I take ownership and drive implementation from inside the business. Not capacity, but the authority to move decisions stuck between procurement, finance and ops.

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

Your system runs. I make sure it stays that way, and the founder stays out of operational firefighting. For good.

  • Monthly Review
  • KPI Monitoring
  • Escalation Support
Who Closes the Gaps
Marco Koehler

I’ve seen the gaps.
Over and over.

15+ years. Procurement, planning, and Supply Chain architecture.

For over 15 years I’ve been inside Supply Chains. As a procurement lead, as the builder of the planning systems D2C brands run on, and as the person founders called when things stopped scaling. I ran global procurement at Jägermeister, built the inventory tools behind some of the fastest-growing brands in DACH, and ran Supply Chain at Glow25 through its scale from €30M to €120M.

I know what breaks. I know why. And I know how to close the gap before it costs you.

Hidden Gaps

Good numbers hide bad gaps.

Everyone knows the one KPI that sounds strong and still hides a problem: revenue. It is not profit. Your Supply Chain runs the same trap. The number looks healthy while the gap sits right behind it.

< 8% out-of-stock
Looks good. Hides this:

Cash parked in inventory to keep it there.

> 8x / yr turnover
Looks good. Hides this:

How fast one spike leaves you empty.

That’s the gap you feel but can’t name.

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.

When to Hire

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

Not when things are calm. Not when you’re under €10M. 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 €10M revenue without a system underneath, that’s the moment. Earlier is too early. Later is expensive. And sometimes the answer is not a hire at all, just a structure that stops creating the work.
