The In-Stock Engine: managed inventory planning

You’ll never guess a reorder again.

Every week: suggested POs with SKU, quantity, and order-by date, plus transfer recommendations, risk flags, and a 30-minute call with the team that built your numbers and stands behind them.

If your suppliers quote lead times of 30 to 120 days, whether you’re in stock on day 90 is being decided in weeks like this one.

The problem

Your next stockout is already scheduled.

If you sell physical products with real supplier lead times, the decisions that make or break your cash are made weeks before the symptoms show. Four ways it goes wrong:

Stockouts that destroy momentum

One stockout on Amazon costs you more than a day of sales. It sinks your BSR and your organic ranking, and the momentum you spent months building goes with it. Recovery takes weeks.

Felt Day 90
Decided The week the order-by passed

Cash trapped in the wrong inventory

Long lead times force you to order months ahead. Order too much and your cash is locked in a warehouse. Order too little and you’re back to stockouts.

Felt Month-end
Decided The week the PO was sized

Data scattered across platforms

Amazon says one thing. Shopify says another. Your 3PL shows a third number. You’re reconciling spreadsheets instead of growing the business.

Felt Every Monday
Decided Never, nobody owns the numbers

The founder is the planner

You’re the CEO, the inventory planner, and the freight coordinator. Every reorder decision runs through your head, and your head is busy.

How it works

One build. Then a weekly rhythm.

We model your catalog once, then run a planning cycle every single week. You don’t get a dashboard to interpret or a junior VA guessing at your numbers. You get a plan, a call, and a team watching between calls.

Weeks 1-3

The System Build

Your sales history, supplier lead times, MOQs, and channel structure, all modeled in a live planning workbook you own.

Proof

Proof, honestly.

We’re a young firm and we won’t invent numbers to look bigger. There are no dressed-up case studies here. What follows is the working record, with the numbers exactly as they happened.

We don’t sell hours. We build the system that tells a brand exactly what to order, move, and watch, and we stand behind it.

Plan

Demand forecasting, days of cover, reorder points and safety stock, all built on your real sales velocity, lead times, and seasonality.

Move

Purchase orders, freight and 3PL coordination, and multi-warehouse transfers into FBA and AWD, across the US, UK, EU, Canada, and Australia.

Watch

KPI dashboards, stockout and overstock alerts, cash-flow and COGS visibility: the weekly rhythm that keeps a catalog healthy.

The working record

Seven active brands · a first launch to a ~200-store retailer · US · UK · EU · CA · AU

216 palletsOne pre-Prime-Day week

Our Place: DTC cookwareNamed client

Multi-region FBA planning and transfer execution across Amazon US, CA, UK, and AU: ~14-15k units moved across nearly every warehouse, ~120k Amazon US units tracked, and a from-scratch transfer workflow that cut carrier cost to under ~$900 per shipment.

4,800 unitsHidden in a SKU mismatch

HODL-21: golf accessories on Amazon + TikTok ShopThe model engagement

A 20% stock undercount caught before it skewed reorders. We also built a live weekly forecasting system in ~30 days, and absorbed a $100/day → $6,000/day TikTok spike with price and ad levers instead of panic orders. The Engine is this engagement, formalized.

20 days’ notice500 pallets relocated

A multi-category Amazon seller: ~500 SKUs

The full supply-chain desk, from order entry to freight triage. That included a 15,000-unit holiday PO out of China, and a lost supplier payment we traced and recovered.

8+ systemsAS400 to Oracle

A US pet retailer: ~200 stores

An embedded team inside merchandising, e-commerce IT, and procurement. We serialized a coupon campaign to 800,000 customers, and caught a failed reindex job that the client’s own IT hadn’t noticed.

Day 90

You just scrolled ninety days.

On the ground they arrive one week at a time, and whether day 90 finds you in stock is decided in the early ones. Bring your stock report to a 30-minute call: we’ll tell you, on the call, which SKUs are at risk in the next 90 days. If we’re not the right fit, we’ll say so.
