What a one-page checkout is
A classic checkout splits the order into steps: first your details, then shipping, then payment, each on its own page. A one-page checkout shows the same parts together. The buyer scrolls instead of waiting for a new page to load.
Depending on your settings, Shopify's own checkout may already show everything on one page. Check Settings and then Checkout in your Shopify admin before you look further. If you want a different look, your own fields or payment providers Shopify doesn't offer you, a custom one-page checkout is the next option.
Why one page helps on mobile
Most store traffic from social ads is on a phone, often inside the Instagram or TikTok app. Every page load is a moment where the connection drops or the buyer gets distracted. Fewer pages means fewer of those moments.
A single page also shows the buyer how close they are. When the pay button is in sight, finishing feels like a small step. And if they make a typo, they can fix it right there without clicking back through earlier steps.
What matters more than the number of pages
A one-page checkout on Shopify won't save a checkout that asks too much or offers the wrong payment methods. These details usually matter more:
- Fewer fields. Do you really need a company name, a second address line or a phone number for every order?
- Local payment methods. A Dutch buyer looks for iDEAL, a Belgian buyer for Bancontact. If it's missing, many leave.
- Clear costs. Show shipping before the last moment, and a free-shipping threshold if you have one.
- Trust near the pay button: secure payment, returns policy and real reviews.
- Your own brand and domain, so the page doesn't feel like a jump to a different site.
- Speed. A heavy page on a slow phone loses buyers no matter how few steps it has.
How Settl's one-page checkout works
Settl gives your Shopify store its own checkout on your own domain, such as checkout.yourstore.com. Contact, delivery and payment sit on one page. On phones everything stacks in one column and the order summary folds away, so the pay button is reached fast.
You choose which fields show up and whether they're optional or required. You add your logo, colours, trust points, a banner or customer reviews, and you see a live preview while you edit. The checkout runs in 8 languages and local currencies.
Payments go through your own provider: Whop, Stripe, Mollie, PayPal, Revolut, Airwallex, Viva.com, Checkout.com, SumUp, Tikkie or Oceanpayment, plus manual methods like bank transfer. Each buyer sees methods that fit their country. Every cart is priced again from Shopify before payment, and every paid checkout becomes a normal Shopify order.
How to tell if it's working
Compare the share of people who start checkout and finish paying, before and after the change. Give it at least a couple of weeks and keep your ads and offers roughly the same, so you're measuring the checkout and not a new campaign.
Also look at where people drop off. If many leave after seeing shipping costs, the problem is the price, not the layout. If many leave on the payment part, check whether the methods they expect are there. A one-page checkout for Shopify makes these problems easier to spot, because everything a buyer sees is on the same screen.
