Inventory Optimization ProAdvisory by Sharon Custer Free 30 minutes

For distributors and manufacturers, $20M to $200M in sales

Find the cash.

Sales are fine. Margin is fine. The credit line keeps climbing, and nobody can see which buying decisions are holding the cash. The decision that hurts is rarely the write-off. It is the purchase approval that made it inevitable.

Find the cash that is already stuck, and test the next commitment before it is signed.

What you get

Know what is stuck, why, and what comes next.

What is stuck

The cash sitting in inventory, in dollars, measured the same way on day 1 and on day 90, so the change is real.

Why

Which buying decisions put it there, so next year's cash does not go the same way.

What is next

The commitment on the desk, tested first: the assumptions named, the week the cash leaves, and what it removes if it is wrong.

Why this works

A $300,000 loan, retired ahead of schedule.

A bespoke build firm was sure it had a cash problem. It had a sequencing problem: materials were bought weeks before the client payments that covered them had landed. Purchases were mapped against cash, week by week, and re-timed. The loan went early. “We thought we had a cash problem. We had a sequencing problem. Nobody had ever drawn the map.”

At a packaging distributor, the bestseller made 35% of revenue and turned 1.5 times a year. It was the biggest drag on working capital, and the company kept buying more of it. Buying was re-pointed at what turned. Storage cost fell 12%.

How it works

3 steps, run as one AI workflow.

Not a question typed into AI. A workflow designed end to end, from the raw exports to the decision, with the same steps and checks every time, so the result repeats, compares month to month, and holds.

4 exports from the inventory system

Products, purchase orders, sales and stock on hand, from whatever system is in place. 12 months minimum. Messy data is fine. It is the normal starting point.

One AI workflow runs the whole analysis

It cleans and joins the 4 exports. It works out why each purchase was made. It traces every dollar on the shelf back to the order that bought it. It measures what is trapped, ranks it by dollars, and drafts the report. Each step is tested against cases where the answer is already known, and it runs the same way next quarter.

The number and the list

The trapped cash in dollars, the decisions behind it, and the list that changes next month's buying.

Time from the team: One kickoff and one readout.

This is how the diagnostic runs, on my workflow. Building one inside your own business is the AI workflow implementation below.

Why now

The questions you stopped asking, answered.

Which purchases are still on the shelf, and who approved them? Which lines give the cash back in a month, and which hold it a year? Nobody asks, because answering meant reading every order and every stock line. So the team watches the top 20 items and hopes the other 4,000 behave. An AI workflow reads all of it, the same way each time, before the next buying meeting and again next quarter. Your competitors are still looking at the top 20.

How it is measured

A number you can compare, before and after.

Found

Trapped cash, identified and priced on day 1. The definition is written down, and the baseline is page 1 of the report. This is what I promise.

Released

How much of it has come back, measured on the same items, the same way, at day 90. Your team's actions release it, and I measure it.

Avoided

Purchases not placed because of the action list. Always labelled as an estimate.

TimeAbout 3 weeks, one time

The true inventory position, the cash and exposure in dollars, and a plan ranked by cash released: a 10 to 15 page report with a one-page summary for a board or a bank. Not included: doing the fixes. That is the AI workflow implementation, quoted once the size is known.

How it runs

Week 0Data lands, the clock startsThe 4 exports. Nothing else is needed from the team until the check call.
Week 1Data checkWhat is missing, what it changes, and what to send. 3 working days to fill the gaps.
Week 2Findings previewThe true number and the dollar impact, before anything is written up. No surprises in the report.
Week 3Report and readoutThe report, the one-page summary and the readout. A number that holds in any room.

What it takes

1ProductsEvery item, with its cost. From Cin7, the ERP, or the spreadsheet actually in use.
2Purchase ordersRaw export, no tidying. 12 months minimum.
3SalesThe same 12 months, by item.
4Stock on handBy item, at a month end already closed.

Messy data is the normal starting point. The work runs on the data as provided, screenshots included, and the report states what any gap does to the answer. The data is used for this work only, never shared, never used as an example, and deleted on request.

Built and handed over: AI workflow implementation

PriceStarts at US$15,000
TimeAbout 3 months

One deliverable: a working AI workflow inside the business, run by its own team. One workflow, named at the start.

Scope and timeline

Weeks 1 to 3MapHow the data moves, and how your people really work: the exports, the reports, and the people who touch the number. You get the workflow map, what is wrong, and the plan. This step alone starts at US$3,500, and you can stop here.
Weeks 4 to 6DesignThe AI workflow, and the few handoffs it depends on: who records what, which date counts, who owns the number. You approve the design before anything is built.
Weeks 7 to 12Build, test and hand overBuilt into your systems, tested against numbers you already trust, and run by your team, with me beside them for the first month.

In scope: one workflow, named at the start, such as the inventory close, the buying review or the monthly report, plus the handoffs it depends on. Anything beyond that workflow gets its own quote. Most of the 3 months goes to mapping how the work really gets done, with your people, so the AI fits reality.
