Businesses experiencing weak revenue growth have been advised to examine their sales and customer conversion processes before increasing advertising budgets, as poor lead management and operational failures could be responsible for lost sales.
JG Bezuidenhout, an executive at digital technology company Offernet, said companies sometimes misdiagnose declining sales by blaming marketing campaigns, even when their advertising has successfully attracted potential customers.
In an article issued by Offernet on November 2, 2026, Brandspur Brand News noted that businesses could be losing revenue at several stages between a customer’s first contact with a brand and the completion of a profitable transaction.
Bezuidenhout illustrated the problem with a hypothetical business that generates 1,000 leads but records only 100 sales. Rather than immediately concluding that the leads are poor, he argued that management should investigate what happened after those potential customers expressed interest.
Some leads may never receive a call, while others could be contacted too late or abandoned after a single unsuccessful attempt. Sales representatives may also struggle to address customer concerns, while approved applications can fail to translate into completed purchases.
In retail, the problem could be as straightforward as a customer responding to an advertisement but finding the promoted product unavailable when they visit a store.
These gaps show why the number of leads generated does not necessarily reflect the revenue a campaign produces. A company may spend heavily attracting customers but still lose sales because its internal processes cannot handle the demand effectively.
Bezuidenhout also raised concerns about businesses measuring marketing success through intermediate activities rather than actual commercial results. For instance, lenders should assess completed loan disbursements rather than applications alone, while retailers need to focus on profitable purchases instead of abandoned or incomplete shopping carts.
The growing use of artificial intelligence in digital advertising makes accurate measurement even more important. Platforms such as Google and Meta use the performance signals supplied by advertisers to optimise campaigns. If a business treats completed lead forms as its main measure of success without feeding actual sales and customer value back into the system, its advertising algorithms may continue attracting people who are unlikely to generate revenue.

The problem can become more difficult when departments operate with disconnected information. Marketing teams track where customers originate, customer relationship management systems record lead activity, call centres monitor contact attempts, while finance departments assess payments and profitability.
Without a connected view of these activities, management may struggle to identify where potential revenue is being lost.
Offernet describes this wider commercial process as the Offer Network, linking customer acquisition with sales, fulfilment, revenue, profit margins and customer retention. The company argues that information from completed transactions should also guide future marketing decisions.
For businesses operating in competitive markets, the implication is that increasing advertising expenditure may not solve poor sales performance. If customers are already being attracted but are not progressing through the buying process, additional campaigns could increase costs without delivering the expected financial returns.
Bezuidenhout said companies should assess the entire process before spending more money to generate new leads, rather than judging marketing performance by the volume of enquiries alone.
