Europe's twelve percent online grocery ceiling
What McKinsey's 2026 grocery report implies for European fulfillment strategy
McKinsey’s State of Grocery North America 2026, published in June, ranges across value, private label, retail media and AI. Its most consequential finding for European operators is a single line about fulfillment capacity:
“Manual store-based fulfillment tends to hit a ceiling at around 12 to 15 percent online penetration.”
This ceiling is a hard, structural limit, beyond which further effort inside the existing model stops producing additional capacity.
McKinsey’s report is precise about why this is true for the US: Namely, a large majority of online orders are picked inside ordinary supermarkets by on-site staff manually assembling baskets rather than using dedicated capacity. That arrangement worked, McKinsey notes, “when online penetration was lower, labor was cheaper, and retailers could keep pace by getting better at in-store picking.” Demand is now concentrating in metropolitan areas where store footprints have barely grown. McKinsey models a $20–30 billion gap between US online grocery demand and fulfillment capacity by 2030—after accounting for every expansion retailers have already announced.
The conclusion follows directly: The next wave of growth “may not be absorbed by adding more pickers into already congested stores but will require different fulfillment models altogether.”
Why Europe will hit this ceiling first
McKinsey’s numbers are North American; the physics are not.
Europe will reach this threshold much sooner, which can mean within the next year or two. European cities are denser, stores are smaller and hold less back-room slack, and labor is both more expensive and more strongly protected. Several European markets already sit within or above the 12–15% band McKinsey identifies, which makes this a current operating condition rather than a 2030 planning assumption.
Europe also has less margin available to absorb it. The State of Grocery Retail Europe 2026, published by McKinsey and EuroCommerce in April, characterizes 2025 as “low-growth stabilization under sustained profitability pressure.” Sales grew 3.4%, up from 2.4% in 2024, but 77% of CEOs name cost and margin pressure as their top-of-mind concern, and volume is projected to grow at a 0.2% compound annual growth rate (CAGR) through 2030. Online, meanwhile, grew 6.8% in 2025; roughly twice the rate of the market as a whole. That means online penetration keeps pushing toward the ceiling even as cost pressure elsewhere in the business intensifies. Capital intensity is edging up, with digital and AI spending outpacing industry growth—yet only 3% of CEOs report an earnings before interest and taxes (EBIT) increase of more than 5% from AI. Additional capital deployed against existing operating models is not currently producing a commensurate return.
The cost of building ahead of demand
The same McKinsey paragraph observes that “several centralized fulfilment bets have been rolled back.” It would be easy to read that as evidence that dedicated fulfillment has been tried and found wanting.
The more accurate reading is narrower. What was tested was a particular capital thesis: build very large, heavily automated facilities, commit several hundred million in capital ahead of demand, and rely on future volume to justify it. Where volume arrived more slowly than the model assumed, the economics never closed. Rather, this is a failure of capital structure and sequencing rather than of dedicated fulfillment as such.
McKinsey makes a version of the same point elsewhere in the report: “profitability will be achieved through deliberate model design rather than scale alone.”
Between a congested supermarket and a facility built for volumes that have not yet materialized, there is a third position — a lean fulfillment center, sized to demonstrated demand, in which automation is applied selectively where it earns its capital and process design carries the rest.
What that looks like in operation
These are documented weekly averages from Oda’s Oslo fulfillment center, September to December 2025:
Units fulfilled per labor hour — Oda Norway: 301 · Other online grocers: 50–240
Waste (% of operating revenue) — Oda Norway: 0.24% · Other online grocers: >1%
Item accuracy — Oda Norway: 99.72% · Other online grocers: <99%
Deliveries per hour — Oda Norway: 4.2 · Other online grocers: 2–3
Drops per vehicle route — Oda Norway: 30.2 · Other online grocers: 15–25
These map closely onto McKinsey’s ranking of the levers grocers consider most critical to e-commerce profitability over the next two to three years: reducing last-mile costs (52%), increasing basket size (45%), adjusting delivery fees and minimums (38%) and automating fulfillment (38%). Drops per vehicle and deliveries per hour are a direct expression of last-mile cost; units per hour and waste are a direct expression of cost to serve. The levers the industry has identified are the same ones these figures measure.
Growth without economics is not a strategy
The phrase is McKinsey’s, and it is the appropriate conclusion. The ceiling is a structural feature of store-based picking, European operators will encounter it before their North American counterparts, and additional picking labor doesn’t move it. What will break this ceiling is a fulfillment model designed around cost to serve from the outset.
Oda Systems licenses that model—the software, process design and operational playbook behind the figures above—to retailers who’d rather adopt the economics than spend a decade developing them.
