If you’re a media buyer, you know the struggle is real. One moment, you’re gearing up to launch a high-stakes campaign; the next, your card gets declined, your budget is stuck in processing limbo, and your carefully planned strategy is derailed. In an industry where milliseconds can make or break a bid, outdated payment systems are more than an inconvenience—they’re a competitive disadvantage. But here’s the good news: financial technology is finally catching up to the speed of digital advertising. This is where Wallester Business steps in, providing agile, scalable, and stress-free payment solutions designed for the unique demands of media buyers. Let’s break down the biggest payment challenges in media buying—and how to leave them in the past.
Three Key Challenges of Conventional Payment Methods
Overcoming the limitations presented by traditional payment methods is key to optimising campaigns and maximising results. Here are three common challenges we see in this business area and how to turn them into opportunities:
1. Restrictive credit limits:According to WARC, global advertising spending exceeded $1 trillion for the first time in 2024. Media campaigns often require fast, large-scale transactions, especially for programmatic ads or time-sensitive placements. Traditional corporate cards usually impose restrictive credit limits in this area, forcing teams to split payments or delay purchases.
2. Delayed transaction processing:Grand View Research reports that the global programmatic advertising market size was estimated at USD 678.37 billion in 2023 and is expected to grow at a rate of 22.8% between 2024 and 2030. Since programmatic advertising is often fully automated, it does not allow for a delay of even a few minutes. If this happens, it can mean the loss of a bid for premium advertising space or missing a campaign launch deadline. Conventional bank transfers or card approvals often involve waiting times, leaving teams scrambling.
3. Manual tracking of expenses:More than 40% of workers surveyed by Smartsheet spend at least a quarter of their working week on manual, repetitive tasks, with email, data collection and data entry taking up the most time. How much time and money does this cost a company? Or worse, how many mistakes are made in the process? Manual reconciliation of expenses is time-consuming and error-prone. Teams often juggle spreadsheets to keep track of invoices, leading to mismatches, oversights or even fraud. And when you’re buying advertising across multiple campaigns and platforms for different clients, getting your invoicing and reporting in order can be grueling.
Detailed Media Buying Solutions
According to a report by IBISWorld, the European advertising agencies market is set to reach €219.8 billion by 2025, with over 447,000 agencies operating in 2024 and an annual growth rate of 3% since 2019. In such a dynamic industry, having efficient financial tools is essential. Wallester Business provides specialised solutions that ensure financial flexibility, operational speed, and automated control to optimise every advertising investment.
