You can have the perfect product, the right price, and a steady stream of paid traffic. But if the final steps of the customer journey are slow or confusing, none of it matters – shoppers simply leave.

Every bit of friction in your checkout is a direct hit to your margin.

That friction is almost always a combination of a payment step that feels untrustworthy and a delivery promise that feels inflexible. When payment and fulfilment aren't connected, the customer feels the gap.

Together with Sendcloud, here we show how you can build a checkout that actually drives conversion by bridging the gap between payment and delivery.

"The combination of smooth payments via Mollie and efficient order processing through Sendcloud helps us keep our operation scalable and reliable. While Mollie creates a seamless checkout, Sendcloud ensures we deliver quickly and without errors. This has a massive impact on repeat purchases." – Dean van Aalst, Chief Operating Officer, DERYAN

The real cost of checkout friction

The average cart abandonment rate sits at 70%.

When you look at the data, checkout optimisation is the fastest lever for growth you have. You've already paid for the ads and the SEO to get that traffic to your site, so removing checkout friction is the fastest way to capture more revenue.

In fact, data from our European Ecommerce Report shows that large ecommerce sites can unlock up to a 35% increase in conversion purely through a better checkout flow.

But to capture those sales, you need to stop looking at payment and delivery as two separate silos.

Four ways to optimise for the European shopper

Reducing form fields is a good start. But you also need to fix the hidden drivers of checkout friction.

1. Match the payment mix to the delivery method 

Shoppers link how they pay with how they receive their goods. A customer opting for 'Click & Collect' likely expects a mobile-first payment method like Apple Pay or a local option like iDEAL | Wero or Bancontact. When you align payment and shipping choices, you stop forcing customers to compromise.

“At Just Russel, we focus on personalised nutrition plans, and our customers expect that same high level of service at every touchpoint. That’s why we partner with Mollie and Sendcloud. Mollie streamlines local payment preferences like iDEAL | Wero and Bancontact, while Sendcloud does the same for our shipping. Whether a parcel is headed to Antwerp or Amsterdam, Sendcloud allows us to automate the best delivery options, ensuring we can deliver on our personal promise throughout the entire region.” – Mattias Decuypere, Head of Operations at Just Russel

2. Use shipping flexibility to sell more

Delivery drives the sale. Nearly 37% of consumers prioritise affordability over speed. 'Fast' isn't always the goal - 'flexible' is. If you only offer home delivery, you alienate the 58% of European shoppers who prefer pick-up points and lockers. Put these options upfront to turn logistics into a conversion tool.

3. Eliminate the hidden costs 

Unexpected costs are the top reason for cart abandonment. Nearly half (48%) of shoppers drop out when shipping fees appear too late in the payment process. The best checkouts show delivery costs and estimated arrival times immediately – transparency builds the trust needed for them to hit pay.

4. Create a one-click feel (even for new customers) 

Speed is everything, especially on mobile. Using Mollie’s streamlined payment flow alongside Sendcloud’s automated address validation strips out the manual work. The journey feels instant, leaving the shopper with zero time to second-guess their purchase.

How Mollie and Sendcloud drive conversion

Here is how you can boost sales with Mollie and Sendcloud:

1. Build instant trust with a branded checkout 

Redirection kills conversion. Sending a customer to a generic third-party payment page destroys trust. Mollie Checkout lets you customise the look and feel of the payment screen to match your brand perfectly. You keep the experience consistent to build trust and win more sales.

2. Enable one-click speed through tokenisation 

Mobile shoppers demand speed. Mollie uses secure tokenisation to safely store payment data for returning customers. You turn a two-minute process into a 10-second win, giving them zero time to second-guess the purchase.

3. Use Sendcloud’s dynamic checkout for real-time choice 

Delivery isn’t one-size-fits-all. Sendcloud lets you offer home delivery, service points, or evening slots – automatically tailored to your customer’s location and cart value. Showing accurate delivery times and local carriers right in the checkout removes the uncertainty that kills sales.

4. Eliminate errors with automated address validation 

A missed delivery because of a typo is an entirely avoidable cost. Sendcloud automatically validates addresses directly in the checkout. This guarantees that orders are accurate before the customer hits pay, cutting down manual support tickets and ensuring first-time delivery.

“In exclusive sneakers and fashion, it’s all about design and speed. By linking Mollie and Sendcloud, we offer our customers a frictionless experience. The combination of the right payment mix and flexible delivery options of Mollie and Sendcloud means our customers complete their purchase in an instant.” – Lian Gietermans, Founder at SneakerAsk

The conversion formula: effort, choice, and trust

When you treat payment and delivery as a single, unified journey, you solve three business problems at once:

  • You reduce effort: fewer form fields directly equal more completed orders.

  • You increase choice: offering the right payment methods and flexible delivery stops shoppers from bouncing to a competitor.

  • You build trust: a recognisable checkout and clear delivery dates give shoppers the ultimate confidence to convert.

Is your checkout built for growth?

To find out if your current setup is actually working, ask yourself (or your team) these questions:

  • Are you asking for phone numbers and dates of birth when you only need an email and a shipping address?

  • Does your checkout adapt to small screens? If a customer has to zoom in to hit a button or struggle with a tiny keyboard, they’ll leave.

  • Does your payment screen match your brand perfectly, or does it redirect buyers to a generic third-party page?

  • Do you offer the local payment methods? If a shopper doesn’t see their preferred method immediately, they lose confidence in the store’s relevance.

  • Are your shipping fees hidden until the last second?

  • Are you completely ignoring the 58% of shoppers who want pick-up points?

  • Do you have avoidable address errors? 

  • Are you wasting hours manually fixing address typos and answering 'where is my order?' tickets?

Fix the buyer experience

Your checkout shouldn’t be a hurdle. It should be a rapid, logical transition from the cart to the doorstep.

When you stop treating payment and shipping as isolated silos, your entire operation shifts. By connecting Mollie and Sendcloud, you remove the friction that kills conversion. Your sales go up, your manual admin drops, and your buyers actually keep coming back.
