The verdict in three sentences
An Amsterdam e-commerce funnel loses on average 70 % of carts before payment, and most of it plays out in the last three steps. Targeted optimization (1-click payment, wallets, fewer fields, A/B tests) costs 5,000 to 20,000 EUR and recovers 10 to 20 % conversion in 3 to 6 weeks. ROI is measured in weeks once revenue exceeds 100,000 EUR/month, because every conversion point is expensive.
Where the funnel leaks: the costed diagnosis
Before paying for a redesign, you need to know where the money leaks. Here is the typical drop-off of a non-optimized e-commerce funnel in 2026 (estimate on 10,000 visitors).
| Funnel step | Pass-through rate | Remaining visitors |
|---|---|---|
| Product page | 100 % | 10,000 |
| Add to cart | 12 % | 1,200 |
| Checkout start | 55 % | 660 |
| Shipping entry | 78 % | 515 |
| Payment page | 82 % | 422 |
| Payment confirmed | 74 % | 312 |
Overall conversion lands at 3.1 %. Each point gained at checkout (from 74 to 84 % for instance) adds about 42 orders on this volume: at an 80 EUR average basket, that is 3,360 EUR of revenue recovered per 10,000 visitors.
The optimization levers and their impact
Not all levers are equal. Here are observed gains and costs in Amsterdam in 2026 (ballpark).
| Lever | Estimated conversion gain | 2026 cost (EUR) |
|---|---|---|
| 1-click payment / wallets | +6 to +12 % | 3,000 - 6,000 |
| Guest checkout (no account) | +10 to +15 % | 2,000 - 4,000 |
| Fewer fields (10 -> 5) | +5 to +8 % | 1,500 - 3,000 |
| Transparent fee display | +4 to +7 % | 1,000 - 2,500 |
| Continuous A/B tests (3 months) | +5 to +10 % cumulative | 4,000 - 8,000 |
| Abandoned cart recovery | +3 to +6 % | 2,000 - 4,000 |
The winning combo for most SMEs: guest checkout + wallets + fewer fields, i.e. 6,500 to 13,000 EUR, shipped in 3 to 4 weeks, for a realistic cumulative gain of 12 to 18 % conversion.
Mini case study
Thomas, e-commerce director of a sportswear brand in Amsterdam, takes 140,000 EUR/month with 2.8 % conversion. His checkout forces account creation and 11 fields. After an 11,000 EUR redesign (guest checkout + Apple/Google Pay + cart recovery), conversion rises to 3.3 %, i.e. +18 %. Concretely that is about +25,000 EUR monthly revenue, of which ~40 % margin, i.e. 10,000 EUR margin/month. The project pays back in just over a month, then every month is net gain.

FAQ
How much does checkout funnel optimization cost in Amsterdam in 2026?
Between 5,000 and 20,000 EUR depending on how many levers you activate. A targeted pack (guest checkout + wallets + fewer fields) fits within 6,500 to 13,000 EUR, shipped in 3 to 4 weeks.
What is a normal cart abandonment rate?
The 2026 e-commerce average is around 70 %. A well-optimized funnel targets 60 to 65 %, which already means 5 to 10 conversion points recovered.
Is 1-click payment worth the investment?
Yes, especially on mobile: Apple/Google Pay wallets add 6 to 12 % conversion. The integration cost (3,000 to 6,000 EUR) pays back quickly from 50,000 EUR monthly revenue.
How long to see results?
Structural gains (wallets, guest checkout) show up as soon as you go live. A/B tests need 4 to 8 weeks of traffic to be statistically reliable.
Redesign the whole site or just the checkout?
In 80 % of cases, targeting the checkout and cart is enough. A full redesign is justified only if the catalog and product pages convert as poorly as payment.
