Inventory Optimization ProAdvisory by Sharon Custer Book a free review

Advisory for distributors and manufacturers

Find the cash.

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

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

15% of the buying. 39% of the trapped cash.

Crestline Supply is a constructed $36M distributor, built so the method can be shown end to end with the data published. Its reports already said which items were stuck. None of them could say which kind of decision put them there. Once every purchase was traced back to the decision behind it, vendor programs turned out to be 15% of purchase dollars and 39% of trapped cash. 40 cents of every vendor-deal dollar was still on the shelf.

How it works

3 steps, run as one AI workflow.

Anyone can ask AI a question. This is a workflow designed end to end, from the raw exports to the decision: the same steps, the same rules and the same checks every time, so the result can be repeated, compared month to month, and defended.

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: About 4 hours across the engagement, mostly one kickoff and one readout.

This is how I run a diagnostic, with my own workflow, to get you the answer. Building a workflow inside your own business is the AI workflow implementation below.

Why now

The questions you stopped asking, answered.

Every finance team knows the questions worth asking about inventory. Which purchases are still sitting on the shelf, and who approved them? Which product lines give the cash back quickly, and which hold it for a year? What happens to cash if the next big order goes ahead? They go unasked because answering them meant reading every purchase order, every sale and every stock line, and nobody has those weeks. So the team looks at the top 20 items and hopes the other 4,000 behave. An AI workflow reads all of it, every item and every order, the same way each time. The answers arrive before the next buying meeting, and again next quarter without starting over. 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.

Written findings: Focused Diagnostic

PriceUS$1,500

Fixed and running inside the business.

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.
