If you’ve ever told a customer their parcel will arrive in 3 to 5 working days and secretly had no idea whether that was true, this one’s for you. 

Carrier estimates are based on averages. They don’t account for your specific customers, your specific regions, or the reality of how deliveries actually play out on the ground. The result? Missed expectations, frustrated customers, and a support inbox full of “where is my order?” queries. 

Voila’s AI-Powered Delivery Window Predictions change that. 

Introducing AI-Powered Delivery Window Predictions 

Voila now generates a predicted delivery window for every single shipment, regardless of whether your carrier provides one. This isn’t a rough estimate borrowed from the carrier. It’s a data-backed prediction, built from our analysis of real-world delivery performance across specific postcodes and regions. 

Every shipment gets a delivery window. Every time. Even when your carrier gives you nothing to work with. 

These predictions slot directly into your post-purchase communications. Your customers always know when to expect their order. You’re always setting expectations you can actually meet. 

How Does It Work? 

Voila sits across a large dataset of historical delivery performance. For each shipment, we analyse: 

• The destination postcode and region 

• The carrier being used 

• Historical delivery times for similar shipments to that area 

• Seasonal and operational patterns that affect real-world delivery speed 

From this, our model generates a delivery window grounded in what actually happens, not what the carrier hopes will happen. 

Why Does This Matter? 

The gap between what merchants promise and what customers experience is one of the biggest drivers of post-purchase friction. When a customer expects Thursday and gets Saturday, they don’t just get annoyed. They email. They raise a dispute. They leave a review. 

WISMO (“Where Is My Order?”) queries are consistently among the highest-volume contacts for eCommerce support teams. 

Accurate delivery predictions help you: 

• Set realistic expectations from the moment of purchase 

• Reduce WISMO queries to your support team 

• Build customer trust through consistency and transparency 

• Improve your overall post-purchase experience without changing your carriers or operations 

This is about giving customers the confidence that you know what you’re doing, even when logistics throws a curveball. 

What About Carriers That Already Provide Estimates? 

If your carrier already provides delivery windows, Voila uses those alongside our own predictions. For carriers that provide no data at all, Voila fills the gap entirely, so you’re never left with a blank where an ETA should be. 

The goal is consistent, accurate delivery information across every shipment in your account, regardless of which carriers you use.

Do I need to change anything in my current setup? 

No. AI-Powered Delivery Window Predictions are available to all Voila merchants with nothing to install or configure. Once enabled from your dashboard, predictions flow through automatically. 

How is this different from what my carrier already provides? 

Most carrier ETAs are derived from service-level averages. Voila’s predictions are built from actual delivery performance data for specific postcodes and regions, using the same carrier you’re already shipping with. The result is a window that reflects what genuinely happens to your customers’ orders, not a best-case average. 

Better delivery expectations. Fewer support queries. Happier customers. That’s the outcome. The AI is just how we get there.
