How to Prevent Overselling Across Multiple Warehouses and Sales Channels for Chemical Suppliers

Overselling across multiple warehouses and sales channels happens when a business accepts an order for stock that is no longer available. For businesses operating across warehouses, physical stores, websites, marketplaces or B2B sales channels, fragmented inventory information can make this difficult to prevent.

A product may appear available on one channel even though it has already been sold or reserved elsewhere.

The result can be cancelled orders, delayed fulfilment and dissatisfied customers.

 

Why does overselling happen?

The most common cause is disconnected inventory information. A business may hold stock across several warehouses while receiving orders through its website, physical stores, distributors and direct B2B sales. If each channel uses separate inventory records, delays between sales and stock updates can lead to inaccurate availability.

For example, if Warehouse A holds 100 units and 30 are sold through one channel, another channel may still display all 100 units as available. A further order could then exceed the stock available for fulfilment.

Manual spreadsheets and delayed updates make this more difficult, particularly when stock is being transferred or reserved for existing orders.

How can you prevent overselling?

Start with a centralised view of inventory across warehouses and sales channels.

Inventory records should reflect sales, reservations, transfers and incoming stock across the business. Real-time or near-real-time synchronisation can help ensure that a sale on one channel is reflected elsewhere.

It is also important to distinguish between physical stock and available stock. Not everything sitting in a warehouse is necessarily available for a new order. Some stock may already be reserved, allocated to a customer or held as safety stock.

Available-to-promise (ATP) inventory helps businesses determine what they can realistically commit to customers.

How should stock be allocated?

Orders may be fulfilled from the warehouse closest to the customer, the location with the highest available stock or according to specific product and customer requirements.

Inventory reservations are also essential. Once an order is confirmed, the relevant quantity should be removed from available inventory or marked as reserved. This prevents the same stock from being sold through another channel.

What should you track?

A reliable multichannel inventory system should provide visibility into:

● Stock available at each warehouse

● Stock reserved for orders

● Incoming inventory

● Transfers between locations

● Orders from different sales channels

● Available-to-promise quantities

● Product-level inventory changes

 

This is particularly important for businesses handling chemicals, raw materials, ingredients and commodities, where products may have different pack sizes, units of measurement, lead times and storage requirements.

 

How can Orbital help?

Managing inventory across warehouses, physical stores and sales channels becomes difficult when orders, storefronts and stock records operate independently.

Orbital by Matta helps businesses connect supplier and distributor operations while managing inventory, orders and storefront activity through a more integrated system.

Preventing overselling requires more than frequent stock updates. Inventory availability, reservations and orders must work together.

For businesses operating across multiple warehouses or sales channels, Orbital provides a more connected approach to inventory and order management.

 

Frequently asked questions

What is available-to-promise inventory?

ATP is the quantity a business can realistically commit to customers based on available and expected inventory.

What is the difference between physical and available stock?

Physical stock is what a business holds. Available stock accounts for quantities already reserved, allocated or otherwise unavailable for new orders.

How does inventory synchronisation prevent overselling?

It helps ensure that changes made by one sales channel or warehouse are reflected across connected inventory records..
