Philip Hall, Managing Director Europe at Rithum reveals that superb listings on marketplaces don’t cut it in 2026. The battleground is now the unglamorous backend of the business, specifically inventory coordination. Get this wrong and Philip says that you are simply automating consumer disappointment!
A curious paradox has emerged in ecommerce. According to the latest eTail Insights survey of industry leaders, 81% of retailers now view marketplaces as the central pillar of their commercial strategy. However, the strategy for digital storefront growth is often outpacing the operations supporting it.
For years, retailers focused on the frontend, perfecting the art of the product listing. But while they have focused on the aesthetics of getting listed, the invisible coordination required to keep those listings accurate, especially as the number of channels and platforms has grown, has become a far more complex challenge.
The listing illusion
Since ecommerce took off, ‘listing optimisation’ has been the holy grail of marketplace success. High-res imagery, keyword-rich titles, and A+ content were the markers of a sophisticated seller. Today, those are merely the table stakes.
The ‘listing illusion’ is the false belief that a polished frontend equates to a healthy business. In reality, everyone now rates their listings as ‘good’. When everyone is optimised, no one has a competitive advantage. The real battleground has shifted to the unglamorous backend, specifically, inventory coordination. The eTail survey found this backend messiness is cited as the top challenge for 40% of retailers.
This comes at a time when an ‘out-of-stock’ notification after a customer has already clicked ‘buy’ damages brand trust faster than ever before. Consumers in 2026 have zero patience for operational lag. If your backend doesn’t align with what your frontend is selling, you’re simply automating consumer disappointment.
Furthermore, retailers are bleeding through ‘invisible losses.’ Cancellations, refunds, and a surge in support tickets are quietly draining margins. In the UK, recent data reveals that returns now cost retailers £100,000 for every £1 million in sales, with the total cost of processing a single returned item often swallowing up to 65% of its original value. While marketing teams, unaware of the friction, continue to pour budget into customer acquisition. It is a leaky bucket that no amount of ad spend can fill.
Bad data poisons the agentic well
The shift towards AI shopping assistants, or ‘agentic commerce,’ has fundamentally changed the stakes of product data. Retailers are no longer just selling to humans who can use intuition to fill in the gaps; they are selling to AI agents that require absolute precision.
In this environment, a messy product catalogue is a liability. If your product data leaves room for interpretation, AI agents will fill in those blanks with hallucinations. Consider a customer asking an AI assistant about the specific compatibility of a spare part or the exact dimensions of a furniture piece. The AI relies entirely on your backend data. If that data is missing or unclear, the AI makes an educated guess. The customer buys, the product doesn’t fit, and a return becomes inevitable.
Crucially, eTail’s survey found 33% of retailers currently rate their reputation management as ‘fair or poor’. In previous years, a three-star review was a blow to reputation. In 2026, those reviews are something far more dangerous: they are data points. AI agents are trained to find the ‘best’ solution for the user. If your review sentiment highlights consistent shipping delays or data inaccuracies, the AI won’t just rank you lower, it will learn to avoid your products entirely.
Fix the foundation before buying the paint
The message right now is clear: retailers must focus on clean ‘data paths’ above all else. It is the digital equivalent of needing to fix the foundations before you start buying the paint for the walls.
Product truth, the concept of a single, accurate version of product data, must be consistent across every single channel before any other scaling can be successful. The winners of 2026 will not be the retailers with the flashiest storefronts or the biggest influencers. The winners will be the retailers that prioritise:
- Inventory accuracy: Real-time synchronisation is essential to prevent ‘sold out frustration. When inventory is wrong, you don’t just lose a sale; you lose ranking, waste support time, and pay for avoidable returns.
- Review management: Treating reviews as a feedback loop for AI training. If customers keep confusing sizes, the fix belongs in the product attributes.
- Operational transparency: Bridging the gap between the marketing team and the warehouse. Retailers must stop scaling ad spend until the data path is clean. Scaling a messy catalogue only increases the speed of error.
As we move further into this agentic era of commerce, the mandate for retailers is simple: Get your house in order. The AI is watching, and it has a very long memory.
