Collecting payment frictionlessly: payment and checkout
Checkout, where money leaks the most
It's the cruelest moment in e-commerce: the visitor liked the product, added it to the cart… then vanishes. On average, around 70% of carts are abandoned, and a huge share of that abandonment happens at payment. The causes are almost always the same: shipping fees discovered at the last moment, forced account creation, too many steps, a missing payment method, or simple lack of trust. Checkout isn't a technical formality: it's the link where one euro of friction costs you a sale.
Every useless field, every extra step, every price surprise is an exit door you open for the buyer.
The payment processor: the heart of collection
This is the tool that charges the card and pays you. The big names:
- Stripe (~1.4% + €0.25 per transaction in Europe): the standard, simple to integrate, accepts cards, wallets, recurring payments. Excellent by default.
- PayPal: reassures many buyers and lets them pay without entering their card; fees a bit higher, but it's a trust signal to offer alongside.
- Local and banking solutions — Mollie, Stancer, SumUp for in-person, or your bank's modules: useful depending on country and customer profile.
On Shopify, Shopify Payments (powered by Stripe) avoids the platform's additional transaction fees — a detail that adds up at scale.
Offering more payment methods
Each buyer has a preferred method; the absence of it is enough to make them leave. Offer at least card, PayPal, and wallets (Apple Pay, Google Pay) that pay in one gesture on mobile. Buy now, pay later (Klarna, Alma, Scalapay: "pay in 3 or 4") markedly raises conversion on high-value carts, for a commission. The rule: cover the methods your customers expect, without drowning the page under twenty logos.
Reducing funnel friction
A few principles win conversion points immediately:
- Guest checkout: never force account creation before purchase. Offer it after.
- As few steps as possible: ideally one page, only the strictly necessary fields.
- Shipping fees announced early, never as a surprise at the last step.
- Express payment (Shop Pay, Apple Pay) that skips entry for hurried buyers.
- Auto-fill of addresses and real-time field validation.
Trust: the invisible barrier
On an unknown site, the buyer unconsciously wonders: "am I going to get scammed?" You defuse this doubt with concrete signals: the HTTPS padlock (mandatory, free today), recognized payment logos, a visible return policy, customer reviews, and clear notices (contact, legal terms, conditions of sale). These elements cost nothing and remove the most powerful barrier to online buying: the fear of being scammed.
The legal frame of payment
Selling online imposes obligations: clear terms and conditions of sale, respect for the right of withdrawal (14 days in Europe for distance selling), an explicit refund policy, and GDPR compliance for customer data. On the technical side, strong authentication (3-D Secure 2) is mandatory for most card payments in Europe; serious processors handle it natively. Tools like terms-of-sale generators (built into Shopify, or dedicated services) help lay this base without a lawyer from the start.
Key takeaways
Checkout is where money leaks the most: 70% of carts are abandoned, often at payment. Choose a solid processor (Stripe, complemented by PayPal), offer the expected payment methods — card, mobile wallets, buy-now-pay-later on big carts — and hunt down friction: guest checkout, a single page, shipping fees announced early, express payment. Reassure with trust signals (HTTPS, reviews, return policy) and hold the legal frame (terms of sale, withdrawal, 3-D Secure, GDPR). The order is collected — but it must actually reach the customer: on to logistics.
