What Is a Customer Order Discrepancy?

← Back to all blogs

A customer order discrepancy is any difference between what a customer ordered and what was entered, shipped or invoiced. It covers wrong products, wrong quantities, wrong prices and missing lines, whether the mistake happened at the order desk, in the warehouse or in finance.

Discrepancies are costly because they are usually found late. By the time a retailer notices, the goods have been delivered, the invoice has been raised and fixing it means a credit, a return or a second delivery.

Types of order discrepancy

TypeWhat happened
QuantityDifferent amount shipped than ordered
ProductWrong item supplied, or an unapproved substitute
PriceInvoice price differs from the agreed price
Missing lineAn item on the PO never made it onto the order
DuplicateThe same order entered twice
Unit of measureCases supplied where eaches were wanted, or the reverse
DeliverySent to the wrong site or on the wrong date
DocumentationDelivery note or invoice does not match the shipment

Where discrepancies come from

Manual entry. Keying orders by hand introduces wrong SKUs, quantities and prices. This guide covers ways to reduce manual order entry errors in wholesale.

Unclear orders. Free-text emails and handwritten faxes are open to interpretation.

Unconfirmed substitutions. The rep swapped an item, but the retailer never agreed to it.

Stale pricing. The invoice used a price that had changed.

Verbal orders. Phone orders taken without a written confirmation leave nothing to check against.

Warehouse picking. The order was right, but the wrong item was picked.

Who absorbs the cost

Discrepancies create work for several teams at once. The order desk investigates, the warehouse arranges a return or redelivery, finance raises a credit and the sales rep smooths things over with the account. The direct cost of the goods is often the smallest part.

For retailers, the cost is empty shelf space and lost sales, which is what drives them to call a competitor next time

How to prevent discrepancies

Validate before entry. Check every line against the catalog, pricing and stock as the order arrives.

Confirm every order in writing. A clear confirmation gives the buyer a chance to catch errors before the truck leaves.

Get substitutions approved. Never swap an item without the retailer agreeing.

Record verbal orders. Write up phone orders and send them back for confirmation.

Remove retyping. Capturing order data automatically removes a whole class of errors. This overview of data entry automation explains the approaches.

Track discrepancy causes. Logging what went wrong shows whether the problem sits in capture, picking or pricing.

How Ordana helps

Ordana prevents most discrepancies at the point the order is captured. The Ordana Desk Agent reads the original order document, so the retailer’s actual request stays the reference point rather than a rep’s interpretation of it. Every line is validated against live catalog, pricing and inventory data before the order is entered.

Substitutions are never silent. The agent contacts the retailer, proposes the change and only closes the order once they approve it, then states the change in the confirmation. Phone orders are captured and confirmed in writing too, so there is a record on both sides. Ordana reports a 95% decrease in order entry errors for its customers.
