The problem

Supply chain doesn't fail in one place. It bleeds in six.

Most teams treat these as separate fires. They aren't. They share a common root: a plan built on incomplete visibility and a demand signal that was wrong before it left the spreadsheet.

No visibility

Inventory is somewhere in the network — in transit, stuck at a DC, quarantined, mislabeled. Nobody can answer 'how much do we really have, where, and usable when?' without a spreadsheet marathon.

Stockouts and overstocks — together

The same SKU is empty in one store and piled up in another. They aren't opposite problems; they're the same broken allocation showing up in two places at once.

Margin erosion

Excess ages into markdowns, expedites paper over misses, and the cost of carrying the wrong mix compounds silently until it hits the quarter.

Shrink and write-offs

Product that sits too long walks, expires, or gets damaged. Every extra week of cover is another week of shrink risk you can't see in the forecast.

Lost sales invisible to the P&L

A customer who leaves empty-handed doesn't file a report. Censored demand hides the real gap between what you sold and what you could have sold.

Planners drowning in exceptions

Teams spend the week rebuilding the plan in Excel instead of acting on it. By the time the meeting starts, the numbers are already stale.

What we propose

One planning layer that sees the network end-to-end, decides continuously, and learns from every miss.

Praxima unifies visibility, forecasting, inventory policy, allocation, and replenishment in a single control loop — supervised by your planners, auditable line by line, and running in parallel to your ERP so nothing has to be replaced to prove it works.

It starts with a reconciled view of inventory across every node and status, so you know what you really have, where, and when it becomes usable. It reconstructs demand signals that account for stockouts, promotions, seasonality, and new product behavior. It turns those signals into SKU-level policies — safety stock, reorder points, lot sizes, cover targets — that adapt as lead times and volatility change.

Then it pushes recommendations into purchase orders and transfers, and explains every number so your team can approve, challenge, or override in minutes, not days. The loop keeps learning: every miss is fed back, every override is captured, and the next plan is sharper than the last.

Your network is yours

Why one-size-fits-all fails

Your network
Nodes, echelons, lead times.
Your catalog
Fast movers, long tail, private label.
Your demand
Seasonality, promotions, events.
Your flow
How product moves from source to shelf.

"The value isn't the model. It's the model tuned to your data."

Under the hood

Not "we do AI." Here's the engine.

A full planning stack — visibility, inventory policy, allocation, and forecasting — wired into one loop. Forecasting is one pillar, not the whole product.

Network-wide visibility
Every node, echelon, and transit lane in one live picture — on-hand, in-transit, committed, and usable stock reconciled continuously.
Dynamic inventory policy
Safety stock, reorder points, and target cover recomputed per SKU × node from real service targets and distributional lead times — not static Excel rules.
Allocation & replenishment
Rebalance stock across the network and turn plans into purchase and transfer orders that respect MOQs, capacity, and supplier calendars.
Scenario simulation & S&OP
Test promo, price, and supply scenarios and see the impact on service, working capital, and margin before you commit the plan.
Multi-model forecasting
Statistical, gradient-boosting, and deep-learning models compete per series — auto-selected per SKU × node with probabilistic P10/P50/P90 outputs.
Lost-sales reconstruction
Recover the true demand hidden behind stockouts and censored sales, so error stops compounding into the next plan.
Agentic replenishment

AI runs the loop. A planner stays in charge.

Praxima closes the loop from signal to purchase order with an explainable, human-in-the-loop workflow — so planners supervise the work instead of drowning in it.

Sense
Continuously read demand signals, stockouts, promotions, and supplier lead-time changes.
Recommend
Propose forecast adjustments, safety-stock changes, and replenishment orders with a rationale.
Supervise & approve
A senior planner reviews recommendations, approves in bulk, or overrides — the loop learns from every decision.

Ask why a number moved — not a black box.

Every recommendation comes with a plain-language rationale. Planners can interrogate any number, challenge assumptions, and feed corrections back into the models. Trust is built through transparency.

Why did the forecast rise for weeks 6–9?
Three drivers combined: a seasonality shift pulling Easter demand a week earlier, an overlapping promotion at S011 and S012, and a supplier lead-time increase from 12→17 days that raised recommended cover.

Test Us · 4-week Proof of Value

Don't trust us. Test us.
On your data. Against what you run today.

No slideware, no cherry-picked demo. Send us your history and we'll run a backtest head-to-head with your current planning solution. Same SKUs. Same weeks. Same rules. A scoreboard at the end — and you keep it either way.

WAPE
Weighted Absolute % Error

The honest accuracy metric. Weights errors by volume, so misses on your fast-movers count more than misses on the long tail. Unlike MAPE, it doesn't blow up on low-volume SKUs — which is exactly where most forecasts lie about themselves.

Bias
Systematic over/under-forecast

Accuracy without bias is a coin flip. Persistent positive bias means chronic overstock and markdowns; negative bias means chronic stockouts and lost sales. We measure it per segment so you can see where the model is quietly costing you margin.

σ
Standard deviation of error

Volatility of the miss. Low σ means safety stock can shrink without breaking service levels. High σ is what forces planners to hold buffer everywhere. This is the metric that translates directly into working capital.

Why these three, together? A model can win on accuracy and still bleed money if it's biased or volatile. WAPE tells you how close on average, bias tells you which direction it's wrong, and σ tells you how wide the miss swings. Read together they predict service level and working capital — not just a leaderboard number.
How the 4-week test works

A blind test. The past is the referee.

Backtesting replays history: we hide the most recent weeks from both models, let each one forecast them, then compare their predictions to what actually happened. It's the only way to compare planning solutions without a year-long pilot — and without either side gaming the setup.

01
You share history
12–24 months of sales, stock and lead times. Anonymized if you want. No integration required for the test.
02
We freeze the past
We hold out the last 8–12 weeks. Neither model sees them. This is the ground truth.
03
Both engines forecast
Your current solution's outputs (or a rebuilt baseline) vs. Praxima — same SKUs, same locations, same horizon.
04
Scoreboard
WAPE, bias and σ side-by-side, sliced by segment, velocity and lead time. Plus a translation to €: stockouts avoided, stock freed.
And if we win?

We show you exactly how we beat your current solution and by how much — then translate that lift into what a better forecast actually unlocks for your business:

Service level
Fewer stockouts on the SKUs and stores that actually drive your revenue.
Working capital
Lower safety stock without breaking availability — cash back on the balance sheet.
Margin
Less firefighting, fewer markdowns and expedites, less shrink on perishables and short-life goods.
Four weeks. Your data. A scoreboard you keep.
If we don't beat what you run today, you'll know exactly by how much — and why.

He has led AI replenishment programs at global retailers and worked as an embedded product leader for private-equity-backed companies, turning ambitious roadmaps into shipped systems. He built Praxima to give mid-market and enterprise teams the caliber of planning intelligence that previously had to be built from scratch.
