Revaion Stock · Inventory optimization for NetSuite · Coming soon

Every line of stock is either earning its keep or eating your cash.
Revaion Stock prices the difference.

Stock intelligence that pays for itself. Revaion Stock reads your NetSuite transactions and prices what your inventory is actually costing you in trapped cash, write-downs and lost sales. Then it recommends the reorder, and can place it for you.

The problem

Nobody set out to trap a million pounds in stock. It accumulated one reorder point at a time.

Inventory is usually the largest number on a distributor's balance sheet and the least governed. The reorder rules were set at go-live. The safety stock was sized for a service level nobody costed. The write-down arrives as a surprise in year three, on stock that stopped moving in month four. NetSuite records all of it faithfully. It just never raises its hand.

  • Reorder points and safety stock set at implementation and never revisited
  • Cash locked in lines that last moved fourteen months ago and still get reordered
  • Write-downs found at year end rather than forecast while there was still time to sell
  • Stockouts on the lines that carry the margin, deep cover on the lines that do not
  • Buying decisions made in a spreadsheet outside NetSuite, then typed back in
  • No single owned number for what carrying this inventory actually costs
18–25%
Where inventory carrying cost is commonly put, per year, once capital, space, handling, insurance, shrinkage and obsolescence are counted. Most reorder rules were set without that number in them.

What it costs

This is a well-measured problem. It is just badly owned.

Six numbers from published research. None of them are ours, and all of them are linked.

$1.73tn

The annual cost of inventory distortion, out-of-stocks and overstocks together, across global retail. IHL puts it at 6.5% of sales, and notes it has barely moved despite billions spent on fixing it.

IHL Group, September 2025
8%

The worldwide average out-of-stock rate in the largest study ever run on shelf availability, covering 72,000 shoppers. Roughly one item in every thirteen somebody wanted to buy.

Gruen & Corsten, GMA / NACDS
31%

Share of buyers who respond to a stockout by buying it somewhere else. A further 9% do not buy at all. The missed margin is the small half of the bill.

Gruen & Corsten, GMA / NACDS
26%

Share of wholesale distributors reporting that 6% to 10% of their stock is dead. In the same survey, 22% are sitting on more than 90 days of cover.

Phocas / Distribution Strategy Group, 2026
31%

Share of distributors with high confidence in their own inventory data. The other 69% are making six-figure buying decisions on numbers they have told a surveyor they do not trust.

Phocas / Distribution Strategy Group, 2026
25%

What excess and obsolete stock costs a typical distributor every year in storage, damage, shrinkage and cost of capital. On £1M of dead stock that is £250,000 a year to keep being wrong.

The Distributor Board, Industrial Supply

Worth saying plainly: three of these six are retail studies, and B2B distribution is not retail. Your buyers are on contracts, they order in patterns, and they will usually wait a day. What does carry across is the mechanism. When the thing is not there, some proportion of demand goes somewhere else and does not fully come back, and almost nobody measures that number because there is no transaction to measure it from.

Inventory optimization

Six inventory optimization engines running on your NetSuite transactions.

Every engine answers the same question in pounds: what is this stock decision worth? Not units. Not days of cover. Not a fill rate percentage. Gross profit protected and cash released.

01 · TRAPPED CASH

Excess, Slow-Moving and Dead Stock

Grade every line by how much working capital it is holding and how likely that capital is to come back. Excess cover, slow movers, obsolete stock and the lines already heading for a write-down, each priced at what releasing them would return.

Finding: £1.12M of stock value sits in lines carrying more than 400 days of cover. £740K of it is still sellable at or above cost today.
02 · LOST GROSS PROFIT

Stockouts Priced in Margin

Stockouts are usually measured as a service level, which flatters the lines that do not matter. Revaion Stock prices each one at the gross profit you did not book, weighted by whether the customer waited, substituted or bought elsewhere.

Finding: 6% of stockouts caused 61% of the lost gross profit, all of them on lines running above 34% margin.
03 · DEMAND & REPLENISHMENT

Forecast, Safety Stock and Reorder Points

Demand forecasting, safety stock and reorder points recalculated per line from real NetSuite order history, lead time variability and supplier reliability. Sized against the cost of holding versus the margin at risk, rather than a service level target applied uniformly across the file.

Recommendation: Cut safety stock on 214 low-margin lines, raise it on 38 high-margin ones. Net effect: £186K of cash released and lost gross profit down.
04 · THE AGENT

It Does the Pass and Shows Its Working

The agent runs the full replenishment review on schedule, drafts the purchase orders, and presents each one with the evidence behind it: the demand signal, the lead time assumption, the cash effect and the margin at risk. You approve, adjust or reject. Nothing reaches NetSuite without that approval.

Monday morning: 43 draft purchase orders, each with its reasoning attached. 31 approved as drafted, 9 adjusted, 3 rejected. Twenty minutes, not two days.
05 · LOCATION

Right Stock, Right Location, Right Time

Multi-site and multi-subsidiary businesses do not have one inventory problem, they have one per location, and the totals hide it. Revaion Stock reads cover, demand and margin per site, and looks for a transfer before it looks for a purchase order.

Finding: 41 lines are stocked out in one warehouse and over-covered in another. Transferring rather than buying releases £128K and spends nothing.
06 · SUPPLIERS

Lead Time and Supplier Reliability

Safety stock exists to absorb supplier variability, so it should be sized per supplier rather than by blanket policy. Revaion Stock measures actual promised-versus-received performance by supplier and by line, and puts the buffer against the supplier genuinely causing it.

Finding: One supplier's lead time varies by plus or minus 19 days and is carrying £96K of safety stock across 34 lines. Two others need almost none.
The commercial angle

Right stock. Right location. Right time.

A business running three warehouses does not have one inventory problem. It has three, and they usually cancel each other out. The line you cannot ship from Midlands is sitting in North with fourteen months of cover on it. You lose the sale, the customer calls someone else, and you pay to hold the stock that would have prevented it.

SKU-4471 · days of cover by location · 38% gross margin

One line, one company, four sites. Total cover is fine. Nothing else is.

Cover held Beyond target Target 60 to 120 days
target band Warehouse North 412 days Midlands 0 days · STOCKOUT · 3 orders unfilled this week South 96 days Dublin 138 days transfer 340 units 0 120 250 450 days
THE SALE YOU NEVER SEE

A stockout does not appear on any report

An order you filled shows up in NetSuite. An order somebody did not place because your rep said "two weeks" does not show up anywhere. That is the whole reason lost sales go unmanaged: there is no record of them to manage. Revaion Stock reconstructs them from quote-to-order drop-off, substitution behaviour, order-line rejections and the ordering rhythm a customer had before it stopped.

Finding: 11 accounts reduced order frequency in the eight weeks after a stockout on their main line. Combined gross profit run-rate down £74K.
THE COST OF BEING SECOND CHOICE

The expensive part is what happens next

The margin on the missed order is the cheap part. The expensive part is that you gave a customer a reason to call a competitor, find out they are fine, and keep calling them. In distribution the switching cost is a phone call, which is why availability on your top-margin lines is a commercial issue rather than a warehouse one.

Rule we apply: a stockout on a 38% line held by a top-quartile customer is worth roughly eleven months of that line's carrying cost. Hold more of it, not less.
How it works

From transaction history to a purchase order you can defend.

Same platform, same principles as every Revaion product: a read-only NetSuite connection to start with, transaction-level analysis, and every output measured in pounds.

01

Connect

A read-only, audited NetSuite role scoped to items, inventory, purchasing and sales history. Write access is a separate, later decision.

02

Price

Every line valued on two axes: the cash it holds and the gross profit it protects. Carrying cost, lead time variability and supplier reliability all included.

03

Recommend

Reorder points, safety stock and order quantities recalculated per line, each proposed change shown with its cash and margin effect.

04

Act

Approve the agent's drafts and it writes the purchase orders back to NetSuite. Or keep it advisory and act on the analysis yourself.

The money

What optimising the stock is actually worth.

A worked model on a £4.8M inventory. The point is not that stock goes down. The point is that cash comes out of the lines that were not earning it, while cover moves onto the lines that carry your margin.

How it compares

Availability is not the same question as profit.

Classic inventory planning tools, Netstock among them, are built to keep stock on the shelf. That is a legitimate goal and they are good at it. Revaion Stock is built to answer a different question: what is this inventory doing to your gross profit and your cash?

Availability-first planning tools Revaion Stock
Optimizes for Service level and fill rate Gross profit protected and cash released
A recommendation reads as Order 240 units. Six weeks of cover. Order 240 units. £14K of cash, protecting £9.2K of gross profit at risk.
Who does the work A planner reviews the dashboard and drives the decisions An agent runs the pass, drafts the orders and shows its evidence. A human approves.
What it reasons over Demand history, lead times and inventory positions The same, plus price, realised margin, cost drift and customer mix from your NetSuite transactions
Where it lives A connected application with its own planning database Inside NetSuite, on the shared Revaion Core context layer
What comes next More inventory features Pricing, supplier recovery, cash and demand intelligence on the same context layer, deployed in days rather than months
To be fair about it. Netstock has spent more than fifteen years on demand forecasting and safety stock mathematics, and it shows. If your problem is genuinely availability, that experience is worth buying and we would not pretend otherwise. Revaion Stock exists because most of the NetSuite businesses we work with do not have an availability problem. They have a profit problem wearing an availability costume: cash trapped in the wrong lines, write-downs nobody forecast, and stockouts concentrated in exactly the products that carry the margin.

Questions

Inventory optimization, answered plainly.

The questions we get asked before the first call, answered the way we would answer them on it.

What is inventory optimization?

Inventory optimization is the practice of setting stock levels so the money tied up in inventory earns its keep. It balances three costs that pull against each other: the cash and carrying cost of holding stock, the gross profit lost when you run out, and the write-down taken when stock stops moving. Most implementations manage the first two and discover the third at year end.

How is inventory optimization different from demand planning?

Demand planning forecasts what customers will buy. Inventory optimization decides what you should hold as a result, and at what cost. An accurate forecast fed into badly set reorder rules still traps cash. The forecast is an input to the decision, not the decision.

Can you do inventory optimization inside NetSuite?

NetSuite already holds everything the calculation needs: item records, purchase and sales history, lead times, costs and inventory positions. What it does not do on its own is price the trade-off between holding cost, lost margin and obsolescence risk line by line, or keep those settings current as demand shifts. That is the gap Revaion Stock fills, without moving your data into a separate planning system.

How does Revaion Stock compare to Netstock?

Netstock optimizes for availability: service level, fill rate and safety stock, refined over more than fifteen years. Revaion Stock optimizes for profit. Every recommendation is priced in gross profit protected and cash released, using the price, margin and customer data sitting alongside the inventory data in NetSuite. It also runs agentically, completing the replenishment pass and presenting its evidence for approval rather than waiting for a planner to drive a dashboard. If availability is your only problem, Netstock is a reasonable choice. If the question is what your inventory is costing you, these are different products.

What does it cost to carry inventory?

Inventory carrying cost is commonly put at 18 to 25 percent of inventory value per year, covering cost of capital, warehouse space, handling, insurance, shrinkage and obsolescence. The right figure depends on your own cost of capital and obsolescence profile, which is why Revaion Stock calculates yours from your data rather than applying a default.

Does it write purchase orders into NetSuite?

Only when you enable it, and only for orders a human has approved. Revaion Stock starts read-only and stays that way until you decide otherwise. Plenty of clients run it advisory for the first few months and act on the analysis themselves, which is a perfectly good way to use it.

What Revaion Stock will not do

Worth saying before you book a call, so nobody wastes an hour finding out.

  • It will not fix your master data. Wrong lead times and missing standard costs produce wrong recommendations, and the first pass usually finds some. We will show you which fields are letting you down, but somebody has to correct them.
  • It will not forecast a product with no history. New lines and one-off specials need a human judgement call, and it will say so rather than inventing a number.
  • It will not replace your warehouse management system. It decides what to buy and what to hold. How you pick, pack and put away is somebody else's job.
  • It will not touch NetSuite without permission. No write access until you grant it, and no order placed without a named human approving that specific order.
  • It will not always tell you to hold less stock. On roughly a fifth of lines the recommendation is to hold more, because the margin at risk is worth more than the cash it ties up. A tool that only ever says "reduce" is not optimising, it is economising.
