Same-Day Delivery in 2026: The Carrier Concentration Trade-Off Every E-Commerce Shipper Should Understand

In July 2026, one of the Benelux region's largest online retailers made a quiet but telling change to its own delivery network. Bol confirmed that every order carrying its Vandaag Bezorgd, or Delivered Today, label would from that point on move exclusively through Ampere, the last mile delivery company Bol built and now owns outright. Same day volume that used to be split across a panel of external carriers now runs through one network only. It is a small operational line item, but it carries a much larger lesson for anyone shipping in Europe this year.

According to the reporting on the change, Ampere's own network currently reaches roughly 85 percent of the Netherlands rather than full national coverage, and its total same day capacity is lower than what Bol's previous multi carrier setup could handle. In practice that means more orders now get bumped down to a Morgen Bezorgd, or Delivered Tomorrow, label at checkout, and the same day cutoff window closes earlier on weekends than it used to. Ampere's footprint is still expanding outward from its original base in Rotterdam and Utrecht into cities such as Zwolle and the area around Nijmegen, but it is not yet everywhere Bol's old carrier panel could reach.

Why a retailer would trade coverage for control

The logic behind Bol's move is not hard to follow. When Vandaag Bezorgd ran across several external carriers, Bol depended on each of those carriers' own priorities, capacity planning, and service quality on a day it did not fully control. A missed slot, a driver shortage, or a regional disruption at any one partner could quietly damage a promise carrying the Bol name. Owning Ampere outright removes that dependency. Bol can plan capacity, train drivers, and fix problems inside its own organisation rather than escalating through a partner's account manager. For a retailer moving the volume Bol moves, that level of control over the last mile is a defensible strategic bet.

The trade-off is not free, and it rarely is

Every consolidation like this comes with a ceiling attached. When a delivery promise runs through one network, that network's limits become the whole promise's limits. A carrier panel of three or four partners can usually absorb a regional gap because another partner covers it. A single owned network cannot, at least not until its footprint catches up. Ampere's 85 percent coverage and its lower same day ceiling are not signs of a badly run operation. They are the mathematically predictable cost of consolidation, and Bol is clearly making a calculated bet that reliability inside a smaller footprint beats broader coverage with less control while the network scales.

Insourcing the last mile is a scale game few brands can play

Building or buying a delivery company the way Bol built Ampere only makes financial sense at enormous parcel volume. Depots, driver employment, routing software, and vehicle fleets carry fixed costs that only spread thin enough to pay off once a business is shipping at a scale most online retailers will never reach. A handful of European marketplaces and large retailers operate at that scale. The overwhelming majority of e-commerce businesses do not, and should not try to copy the Ampere playbook literally.

The useful takeaway from Bol's move is not go build your own carrier. It is get the reliability benefit of ownership without carrying the concentration risk of ownership. That is a software and process problem long before it is a fleet problem, and it is solvable at any scale.

What smaller and mid-market e-commerce brands should take from this

• Treat every delivery promise shown at checkout as a live capacity question, not a fixed label. If your fastest option only holds up because one carrier happens to have room that day, the checkout should know that before the customer pays, not after the parcel is already stuck in a queue.
• Build any fast delivery promise on more than one carrier's capacity, so a regional gap or a sudden volume spike does not turn into a broken promise for every customer caught inside it.
• Measure delivery performance by postcode area or corridor, not only as one company wide average. A coverage gap the size of Ampere's remaining 15 percent hides easily inside a headline number that still looks healthy.
• Keep a fallback label ready, the equivalent of Bol's Morgen Bezorgd, that activates automatically the moment the fastest option cannot be honestly offered, instead of leaving customers to find out from a stalled tracking page.
• Tell customers the moment a promise slips from same day to next day. A proactive message costs a few seconds to send and almost always costs less trust than silence followed by a late parcel.

The real lesson is about orchestration, not ownership

This is precisely the problem an operating system for shipments exists to solve. Zineps was built on the premise that e-commerce brands, and the logistics partners, carriers, and fulfillment providers they work with, should not each be solving this same reliability question from scratch. As we have written before in our guide to building a resilient multi carrier shipping strategy, redundancy across carriers is what actually protects a delivery promise, not loyalty to any single provider, however good that provider's network happens to be on an average day.

Inside Zineps, that redundancy is not a manual fallback plan someone remembers to check during peak season. Delivery promises at checkout are generated from real time carrier capacity by postcode, so a brand can offer same day or next day delivery with the same honesty Bol is now building into Ampere, without needing to own a single van. If one carrier's capacity tightens in a region, the system routes around it automatically, the way our analysis of first attempt delivery performance argues every e-commerce shipper should be measuring in the first place, rather than discovering the gap after a customer complains.

That orchestration extends past the carrier layer. Fulfillment centers and 3PLs feed the same capacity signal, so a delivery promise reflects not just which carrier can move a parcel today, but whether the warehouse behind it can actually get that parcel out the door in time to make the cutoff. Ownership like Bol's solves this by folding everything into one company. An operating system like Zineps solves it by giving every partner in the chain, owned or external, one shared source of truth.

A short framework: reliability through redundancy, not exclusivity

Bol's decision is a rational one for Bol. It is not a template for most of the market to copy, and it does not need to be. The underlying lesson survives the translation to any scale. Reliability is not something a business inherits by picking the right single partner. It is something a business builds by making sure no single partner, owned or external, can quietly become the ceiling on what it promises a customer at checkout. As we explored in our piece on delivery promises that break under real conditions, the businesses that keep their word are rarely the ones with the fastest single carrier. They are the ones whose systems know exactly what they can honestly promise before the customer ever sees a delivery date.

Frequently asked questions

Is same day delivery worth offering if a business cannot guarantee full coverage?

Yes, provided the checkout is honest about it. Bol's own approach proves the point: rather than promise Vandaag Bezorgd everywhere and fail unpredictably, it now only offers the label where Ampere can genuinely deliver it, and defaults everyone else to a dependable next day promise. A partial same day offer that is always kept beats a universal one that sometimes breaks.

Should smaller e-commerce brands build their own last mile delivery network?

Almost never, and Bol's own scale is exactly why. Owning depots, drivers, and routing software only pays for itself at parcel volumes that put a business among the largest retailers in its market. Most e-commerce brands get the same reliability outcome far more cheaply by orchestrating several external carriers through one system rather than owning any single one of them.

What is the biggest risk of relying on one carrier for a delivery promise?

Concentration risk. Whatever limits that one carrier has, whether a coverage gap, a capacity ceiling, or a regional disruption, become limits on every delivery promise the business makes, with no partner left to absorb the difference. Redundancy across carriers is what keeps a single partner's bad week from becoming a business wide problem.

How should e-commerce businesses handle it when a same day promise cannot be met?

Automatically and early. The moment a system knows a parcel will not make the same day cutoff, it should fall back to a clear next day promise and tell the customer immediately, the way Bol's own Morgen Bezorgd label does. Customers forgive an honest downgrade communicated early far more easily than a silent delay discovered on a tracking page.

If your fastest delivery promise depends on one carrier's remaining capacity on any given day, that dependency is worth auditing before your busiest week of the year finds the gap for you. Zineps is the Operating System for Shipments, connecting carriers, fulfillment providers, and logistics partners into one layer that knows what it can honestly promise, before the customer ever has to find out the hard way.
