The Problem

Shoppers Want to Split the Price

It shows up on higher-priced items. Shoppers reach the payment step, see one big total, and leave to think it over. Some don't come back.

  1. 01 · Price shock

    Checkout wants the full price now, and the shopper stops.

    Big tickets get monthly financing, and mid-range carts get split payments.

  2. 02 · Dead badges

    An old app's badge stays while its checkout option vanished.

    Providers get matched to your prices, markets, and platform before setup.

  3. 03 · Stacked offers

    A second provider stacks two offers under every product.

    Shoppers see one clear installment message instead of competing badges.

  4. 04 · Refund gaps

    A partial refund that misses the provider keeps charging your customer.

    Full and partial refunds get tested on every provider before launch.

A shopper adds a $480 jacket to the cart and stops at the payment step. They'd happily pay $120 today, but your checkout wants all $480 now. Or a pay-later app you installed last year still shows its badge under your prices, while its checkout option has quietly disappeared. Add a second provider, and every product shows two stacked offers. Refunds are the hidden risk: if a partial refund doesn't reach the provider, your customer keeps paying for an item they returned.

We start with your prices, markets, and platform, because they decide which providers approve your shoppers. Then we set up the ones that fit, show one installment price per product, and test full and partial refunds on every provider. You get options matched to what you sell, not a row of badges that confuse buyers.

  • Providers matched to your prices

    Monthly financing suits big tickets and four-payment plans suit mid-range carts, so we match providers to your catalog.

  • One message per product

    Shoppers see one clear installment price instead of three competing badges under every product.

  • Refunds checked on every provider

    Full and partial refunds reach the provider, so a returned item stops the customer's payments.

Our BNPL Integration Process

From Review to Launch in Five Steps

You see which providers fit and why, where each message sits, and every test result before shoppers see anything new.

  1. We compare the five main options against your order values, platform, and countries. You get a short recommendation and a fixed quote, or a note that one free setting already covers you.

What's Included

What You Get With Shopify BNPL Setup

  • Provider comparison

    Order limits, countries, and plan lengths for every option, matched against your prices and customers.

    Settings notes for every provider, plus a report of order value by payment method.

What Our Clients Say

What Clients Say After Launch

Feedback from ecommerce teams we have built checkouts, payments, and integrations for.

We were getting plenty of traffic, but far too many people were leaving at checkout. The buying process had simply become too complicated. The team took the time to understand where customers were dropping off, then rebuilt the checkout flow and cleaned up the shopping experience. What I really appreciated was that they didn’t just make the store look better, they actually solved the problems that were costing us sales. The whole store feels faster, simpler, and much easier to buy from now. Exactly what we needed.

Work Culture

Why Merchants Trust Our BNPL Setups

Installment options sit where a shopper decides whether to buy at all. These are the habits we bring to every setup, from one app to four.

  • Price range decides the provider

    Every provider has its own order limits and plan lengths. We compare them with your real prices before recommending one, so the pick fits your catalog.

  • One offer under each price

    Three stacked badges under a price read as noise and slow the page. We show one installment price per product, picked by that product's price.

  • Shopify's own option first

    On Shopify, Shop Pay Installments runs through Shopify Payments and keeps buyers in your checkout. We check it first and add other providers only to cover a gap.

  • Refunds followed to the provider

    A refund in your admin has to reach the provider, or your customer keeps paying for a returned item. We test full and partial refunds before launch.

  • Honest about free setups

    If one provider's free app already covers your prices, we'll say so and show you the setting. You won't pay us for a toggle.

  • Accounts stay in your name

    Every merchant account, app, and payout belongs to your business. We don't keep your provider logins after handover, so you can switch providers any time.

Good fit

  • Shopify stores choosing a first provider

    You know shoppers want to split payments, but every provider promises the same lift, and you can't tell which one fits.

  • Stores selling across wide price ranges

    Your catalog runs from $40 accessories to $2,000 sofas, and one provider rarely serves both ends of that range well.

  • WooCommerce stores adding installments

    Your WooCommerce buy now pay later options sit in WooPayments and separate plugins, and they must work in the Checkout block.

  • Stores whose apps now overlap

    You added two providers over time, and now product pages show stacked badges while one checkout option stopped appearing.

  • Agencies with client BNPL requests

    Your clients want installment options, and you need a partner who sets them up and tests refunds under your brand.

Not a fit

  • Provider already picked

    You've already picked one provider and just need it set up. Our Klarna, Afterpay, Affirm, and Sezzle integration pages cover that for less.

  • Wallet buttons instead

    You want Apple Pay, Google Pay, or PayPal buttons rather than installments. Our Digital Wallet and Express Checkout Integration service covers those.

  • Mostly subscriptions

    Most of your sales are subscriptions, which Shopify's installment option and WooPayments' pay-later methods don't accept. Our Recurring Billing Integration service fits better.

  • Shopify's free option

    You're on Shopify Payments in the US, Canada, or UK and only need Shopify's installment option. It's free to switch on, so our $600 project is more than you need.

FAQ

Frequently Asked Questions

Straight answers on provider fees, timelines, choosing a provider, Shopify's own installment option, and when you need a developer.

  • Each provider charges you a percentage of the order plus a fixed fee, set in your merchant agreement. Rates vary by market, category, and plan length. Stripe's guide to Klarna lists US rates from 3.29% to 5.99% plus 30 cents. Our setup is a separate one-time fee, from $600.

  • One provider usually goes live in about a week, mostly spent on merchant approval and refund tests. Two providers take 1 to 2 weeks, and up to four providers or a second storefront take 2 to 3 weeks. We start the approval paperwork on day one.

  • The best provider is the one that approves your shoppers at your prices and in your markets. Affirm finances purchases up to $30,000, Afterpay and Sezzle focus on four payments over six weeks, and Klarna covers many European markets. We compare them against your real orders.

  • Yes, you can run two or more providers side by side, and each appears as its own checkout option. Shopify lists apps from Affirm, Afterpay, Klarna, and Sezzle beside its own installment option. We show one message per product, chosen by its price, so pages stay clean.

  • The provider pays you the order total, less its fee, and collects the installments from your shopper. Shop Pay Installments, for example, pays out within 1 to 3 business days after you capture payment. If a shopper misses a payment, the provider chases it, not you.

  • Shopify gives you two routes. Its own installment option switches on in your Shopify Payments settings, and providers such as Klarna, Afterpay, and Sezzle install as payment apps. Each app needs an approved merchant account, and product page messaging is set up separately, which we handle.

  • You set up BNPL on Shopify in five steps: apply, install the app, connect your merchant ID, add messaging, and test a refund. Approval is the slow part and sits with the provider. On Afterpay's app, keep test mode off on a live store: Afterpay's docs say the integration fails.

  • Yes, Shop Pay Installments (often searched as Shopify installments) runs next to other BNPL apps, and shoppers pick one at checkout. It's the buy now pay later Shopify built with Affirm, so it needs Shopify Payments and Shop Pay turned on. It can't be used for gift cards or subscriptions.

  • BNPL can raise order value on items where the full price is the objection, because shoppers weigh a smaller first payment. We don't promise a number, since it depends on your prices and customers. Every plan includes a report that splits order value by payment method.

  • Not in every case: Shopify's own option and most provider apps switch on without code. You need help when messaging must fit your theme, providers overlap, or you run a WooCommerce Afterpay setup through its plugin or WooPayments. On the free review, we'll say if the free route covers you.
