How to Manage Available-to-Ship (ATS) Inventory Without Overselling

In wholesale fashion, overselling happens when brands sell more stock to buyers than they can physically produce. To combat this, many brands produce available-to-ship/sell (ATS) inventory that is physically available and not reserved. However, without real-time inventory visibility, numbers can quickly become outdated, and overselling can still occur.

‍

This article will explain how brands can make ATS inventory work for them,  best practices for inventory visibility and allocation across wholesale buyer accounts. 

‍

What Is Available-to-Ship (ATS) Inventory in Wholesale Fashion?

ATS (available-to-ship/available-to-sell) fashion inventory refers to stock that is physically available, unreserved, and ready to be allocated to a new order.

‍

ATS = On-Hand Stock + Incoming Purchase Orders − Committed/Reserved Stock

‍

On-hand stock refers to the total amount of stock a brand has physically sitting in their warehouse. Committed stock includes inventory already allocated to wholesale buyers, DTC orders, or marketplace channels. 

‍

Example: if a brand has 500 units, but 350 are already committed, then there are 150 units of ATS stock.

‍

Why Overselling Happens in Multi-Channel Wholesale Operations 

There are several possible reasons for overselling when dealing with multi-channel wholesale; these include: 

‍

Inventory Data That Updates on Delay

Some brands use data systems that update once a day, but even those that are updating every hour or every 30 minutes are still not fast enough to see real-time inventory updates. 

‍

This means that during the delay, multiple orders can be placed against the same stock, often causing overselling in large quantities. This is not only costly but can also seriously damage retail relationships.

‍

Disconnected Sales Channels 

Fashion brands often sell through DTC, wholesale, marketplace, and retail stores at the same time. If these channels are not connected, each may show different inventory levels, increasing the risk of overselling. 

‍

Multi-channel inventory management helps prevent this by giving all channels access to the same real-time ATS inventory data.

‍

Manual Allocation Across Wholesale Buyers' Accounts 

Manually allocating inventory through spreadsheets or sales teams increases the risk of double-booking stock. This risk becomes even higher during busy periods when many buyers are placed in their seasonal reorders. 

‍

Wholesale overselling has much more serious consequences than DTC overselling, as brand-buyer relationships can often be irrevocably damaged. 

‍

How Real-Time Inventory Visibility Prevents Overselling

Real-time inventory visibility means that all sales channels, including the wholesale buyer portal, always show the latest ATS inventory. When an order is placed, the available inventory is immediately updated, helping to prevent overselling. 

‍

This is especially important for brands selling through both DTC and wholesale channels, as inventory changes in one channel are reflected in the others simultaneously. 

‍

JOOR allows brands to sync data from their ERP to the platform, providing real-time inventory visibility and allowing buyers to order ATS stock easily. 

‍

Practical Steps to Manage ATS Inventory Across Wholesale Buyers' Accounts 

Centralize Data Across Every Channel

All channels should use a single central inventory source so that accurate, real-time data forms the foundation for allocation and stock management.

‍

Set Clear Allocation Rules

Brands should define how inventory is allocated across channels and buyer accounts. Clear rules help protect important wholesale relationships during busy periods. 

‍

Build In Safety Stock 

Keeping a small inventory buffer helps reduce the overselling risk for popular products. Reviewing safety stock levels by product each season is a smart move.

‍

Give Wholesale Buyers Direct ATS Visibility 

Buyers should be able to see real ATS inventory directly in the ordering portal. This improves purchasing confidence and reduces order cancellations.

‍

Review Committed Stock Regularly 

Inventory reviews should include both on-hand and committed stock, as this will help to determine the true ATS figure. 

‍

ATS Visibility Is a Wholesale Relationship Issue, Not Just an Inventory One

ATS inventory management is not just about inventory accuracy. In wholesale, every oversold order can damage brand-buyer relationships and reduce future sales opportunities, so it’s crucial to avoid this whenever possible. Real-time inventory visibility, clear allocation rules, and accurate ATS data help prevent overselling and build buyer trust.

FAQs

What is the difference between available-to-sell and available-to-ship inventory? 

There is no difference between available-to-sell and available-to-ship inventory. Both refer to stock that has already been produced and not yet reserved. 

‍

How often should available-to-sell inventory be updated to prevent overselling?

Available-to-sell inventory should be updated in real time to prevent overselling. Updates that take place every hour or even every 30 minutes still leave room for errors and for the same stock to be allocated twice to different buyers.

‍

What is safety stock and how much should a wholesale brand hold?

Safety stock is extra inventory that acts as a buffer to prevent overselling. A wholesale brand should hold 50% extra stock during peak selling periods.

‍

How do wholesale brands allocate limited stock fairly across buyer accounts?  

Fashion brands with limited stock usually sort their wholesale buyer accounts into tiers and allocate stock based on who they have their most important retail relationships with.

‍

What metrics should a wholesale director track to monitor inventory accurately? 

Looking at the sell-through and stockout rate of inventory will help a wholesale director understand how much stock is needed and help to prevent overselling.
