Backorder: Meaning, Causes, and How Manufacturers Can Control It

A backorder starts with a simple sentence: “We can supply it, but not right now.”

For a manufacturer, that sentence may be acceptable once in a while. But when backorders become routine, they start hurting customer trust, production planning, dispatch schedules, and cash flow. Sales teams keep promising dates. Stores teams search for stock. Purchase teams rush material. Production teams change priorities. Customers keep calling.

Backorders are not just a sales issue. They are a system issue.

AICAN Optiwise helps SME manufacturers manage backorders by connecting sales orders, stock availability, purchase, production, QC, and dispatch visibility.

What Is a Backorder?

A backorder is a customer order that cannot be fulfilled immediately because the required item is not available in sufficient quantity. The order remains open and will be fulfilled later when stock becomes available through purchase, production, transfer, or release from QC.

Backorders are different from cancelled orders. The customer still wants the item. The business has accepted the demand but needs time to fulfil it.

Simple Example

A customer orders 1,000 units. The manufacturer has only 600 units available for dispatch. The remaining 400 units become backordered if the customer agrees to wait.

The business must now track those 400 units carefully. If the backorder is not visible in the system, production may not prioritize it, purchase may not arrange material, and sales may continue promising new orders without understanding the existing shortage.

Common Causes of Backorders

The first cause is inaccurate stock data. If the system or Excel file says stock is available but actual stock is missing, rejected, reserved, or misplaced, orders become backordered.

The second cause is poor demand planning. Sales demand rises but purchase and production planning do not adjust in time.

The third cause is supplier delay. Raw material does not arrive when expected, so production cannot complete finished goods.

The fourth cause is production bottleneck. Machines, labour, tools, or quality issues delay output.

The fifth cause is weak reservation control. Stock is promised to multiple customers because available stock is not clearly separated from physical stock.

When Backorders Are Acceptable

Backorders are not always bad. In some industries, made-to-order or assemble-to-order models naturally create waiting periods. Customers may accept this if the timeline is clear and reliable.

The problem begins when backorders are unplanned, invisible, or poorly communicated.

A managed backorder is a promise with a plan. An unmanaged backorder is a future escalation.

How Backorders Affect Business

Backorders affect customer trust because delivery commitments become uncertain.

They affect cash flow because invoicing and collection may be delayed.

They affect production because urgent orders disrupt planned schedules.

They affect purchase because teams may buy material in panic at higher cost.

They affect management because reports may show sales orders booked but not reveal fulfilment risk.

Backorder vs Stockout

A stockout means stock is unavailable. A backorder means a customer order exists for unavailable stock and is waiting to be fulfilled.

Stockout is an inventory condition. Backorder is a customer commitment problem created by that condition.

Both should be tracked, but backorders require stronger coordination because a customer is already waiting.

Backorder vs Pending Order

A pending order may simply be waiting for routine processing, approval, packing, or dispatch. A backorder specifically indicates that required stock is not available right now.

This distinction matters because a backorder needs purchase or production action, while a normal pending order may only need operational follow-up.

How ERP Helps Control Backorders

ERP helps by showing stock availability before order commitment. It can distinguish physical stock, available stock, reserved stock, rejected stock, and stock under QC.

It can link sales orders with production planning and purchase requirements. It can also show open backorder quantity by customer, item, order date, promised date, and expected fulfilment date.

This visibility helps teams act earlier.

Practical Backorder Control Process

A good process starts when a sales order is entered. The system should check available stock. If stock is short, the order should show the shortage clearly.

The shortage should trigger a decision: produce, purchase, transfer, split dispatch, or revise delivery date.

The customer should receive a realistic commitment based on actual supply and production visibility.

Management should review backorders regularly, especially high-value customers and ageing backorders.

Metrics to Track

Useful backorder metrics include total backorder value, backorder quantity by item, backorder ageing, number of customers affected, average delay days, fulfilment rate, reasons for backorder, and repeat shortage items.

These metrics help the business identify whether the root cause is planning, purchase, production, QC, or master data.

How Optiwise Helps

Optiwise by AICAN helps manufacturers connect sales orders with stock, purchase, production, QC, and dispatch workflows. This makes backorders visible and actionable instead of hidden in phone calls and spreadsheets.

For SME owners, the value is simple: know what is promised, what is short, why it is short, and what action is needed.

Founder’s Note

At AICAN, we have seen that customers can accept an honest delay more easily than a vague promise. Backorders become painful when nobody owns the visibility. Optiwise is built to help teams see shortages early, coordinate action, and communicate commitments with more confidence.
