- High — Shop Pay Installments is first-party, has no activation cost and covers the US, Canada and UK with a $35–$30,000 order window (verified Sep 2026). Klarna and Afterpay are free widgets whose real cost, the merchant fee, isn't published on either listing, so the head-to-head is decided by market reach, not price.

Decision at a Glance
| Your profile | Verdict | Why |
|---|---|---|
| US, Canada or UK store on Shopify Payments | WAIT | Shop Pay Installments is already in checkout at no activation cost, with orders from $35 to $30,000 USD/CAD or £50 to £30,000 eligible (verified Sep 2026). A second widget splits the same shoppers and adds clutter under every price. |
| Selling into European markets | BUY | Klarna wins: Shop Pay Installments serves only the US, Canada and UK (verified Sep 2026), and Klarna's shopper base runs deepest across Europe. Enable the payment method in Payments settings and add the free messaging app (verified Sep 2026). |
| Selling into Australia and New Zealand | BUY | Afterpay wins in its home markets, outside Shop Pay Installments' three countries (verified Sep 2026). The messaging app is free with a single plan (verified Sep 2026), and the same developer lists Clearpay, the company's UK brand, as a near-identical app. |
| Off Shopify Payments, or chasing a proven brand-affinity segment | DEPENDS | Shop Pay Installments requires Shopify Payments and Shop Pay (verified Sep 2026), so a third-party gateway forces a provider: pick by shopper base in your main market. On Shopify Payments, add a second provider only after an A/B test shows incremental financed orders. |
What Klarna vs. Afterpay Actually Drives
| Outcome | Impact | How it works |
|---|---|---|
| Revenue — direct | Medium | Installments lift conversion on considered purchases by splitting the price into smaller amounts; Shop Pay Installments already delivers that lift, so a second provider adds only the shoppers the first one doesn't reach. |
| Customer experience | Medium | One clear installment line under the price answers the affordability question; two competing widgets make shoppers compare lenders instead of buying. |
| Retention & LTV | Low | A provider's own shopper app can send repeat visits, a lever no listing quantifies; treat it as a hypothesis for the A/B test rather than a plan. |
| Operational efficiency | Low | Each provider adds its own payout schedule and reconciliation line for finance, which is a cost the native lane folds into Shopify Payments payouts. |
| Data & insight | Low | Financed-order share shows up in Shopify orders on either lane, while underwriting and shopper-account data stay with the lender on both. |
Spend ceiling: Spend nothing on the native lane, and cap a second provider at what a 4-week product-page test proves: the widget is free, the merchant fee is unpublished until you sign, and an estimated $2,000–$6,000 covers placement and the test (Deploi estimate, illustrative).
What buying enables (top apps)
- + Installments in markets Shop Pay Installments doesn't serve, with the provider's shopper base attached
- + Free on-site messaging on both apps, so the price line shows the installment amount without theme work (verified Sep 2026)
- + A lender brand shoppers already trust: Klarna across Europe, Afterpay in Australia and New Zealand, Clearpay in the UK
What building additionally unlocks
- + No activation cost and no second widget: Shop Pay Installments renders inside Shopify's checkout with nothing to maintain (verified Sep 2026)
- + Orders from $35 to $30,000 USD/CAD or £50 to £30,000 eligible, with Affirm as the named partner collecting installment payments (verified Sep 2026)
- + A clean product page with one installment line, under your theme's control
Find Your Verdict in 3 Questions
Is your store on Shopify Payments with Shop Pay active, selling in the US, Canada or UK?
Yes: Your verdict: WAIT — Shop Pay Installments is already in checkout at no activation cost for orders from $35 to $30,000 (verified Sep 2026); skip both widgets.
No: Go to question 2.
Is the market you need to finance in Europe?
Yes: Your verdict: BUY — Klarna; enable the payment method in Payments settings, install the free messaging app on product pages only, and get the merchant fee in writing (verified Sep 2026).
No: Go to question 3.
Is the market Australia or New Zealand, or do your shoppers already know Afterpay?
Yes: Your verdict: BUY — Afterpay; the messaging app is free with a single plan (verified Sep 2026), and the payment method runs under Afterpay's merchant agreement.
No: Your verdict: WAIT — run a 4-week product-page test of one provider before adding any widget; without incremental financed orders, keep checkout to one installment line.
The TCC Scorecard — 12 Dimensions
TCC — Total Cost of Capability: what it actually costs to have this capability over three years, whichever way you get it. Each dimension is scored 0–5 for both paths. How we score →
| Dimension | Buy | Build | Why |
|---|---|---|---|
| Cost | |||
| Acquisition & implementation | Klarna or Afterpay means enabling the payment method, signing a merchant agreement and placing a free widget (verified Sep 2026); Shop Pay Installments is already on for eligible stores with Shopify Payments and Shop Pay active. | ||
| Recurring fees | Neither Klarna nor Afterpay publishes its merchant fee on the App Store, and Shopify's help pages don't publish the Shop Pay Installments fee either (verified Sep 2026); the native lane at least adds no second fee agreement. | ||
| Maintenance & upgrades | A provider widget is one more script to re-check after every theme update, and Klarna's listing sits at 2.5★ across 101 reviews (verified Sep 2026); Shop Pay Installments renders inside Shopify's checkout with nothing for you to maintain. | ||
| Switching & exit | Dropping a provider means disabling a payment method, deleting a widget and closing a merchant agreement, with nothing of yours stored in the app; the native lane has no exit to plan because nothing was installed. | ||
| Risk | |||
| Vendor risk | Klarna and Afterpay are large lenders, but their Shopify listings sit at 2.5★ across 101 reviews and 3.1★ across 50 (verified Sep 2026), thin for widgets in front of every price; Shop Pay Installments is first-party with Affirm as the named partner. | ||
| Security & compliance surface | Each provider adds a merchant agreement, per-market disclosure rules and a script in the theme; the native lane keeps underwriting with Affirm inside Shopify's checkout, though consumer-credit advertising rules still apply to how you show installments. | ||
| Platform-deprecation exposure | Provider widgets ride theme app blocks, a stable surface; Shop Pay Installments lives inside Shopify Payments and checkout, the surface Shopify invests in most. | ||
| Value | |||
| Fit to requirement | Klarna and Afterpay reach markets and shopper bases Shop Pay Installments doesn't, the one requirement that decides this page; the native lane fits US, Canada and UK stores and excludes gift cards and subscriptions (verified Sep 2026). | ||
| Time to market | A provider takes a merchant agreement, approval and a widget placement, usually 1–2 weeks (Deploi estimate, illustrative); Shop Pay Installments is live the day you meet eligibility. | ||
| Performance & scale | A messaging widget is a script under every price on every product page, and two providers means two; the native lane adds no third-party request. | ||
| Data ownership & AI-readiness | Orders, customers and payment status stay in Shopify on both paths; the lender keeps underwriting and shopper-account data on either lane, Affirm included behind Shop Pay Installments. | ||
| Focus & opportunity cost | A second provider is a small decision that eats real attention: fee negotiation, disclosure review and an A/B test; the native lane costs nothing and asks nothing of the team. | ||
The App Landscape
| App | Status | Pricing | Best for |
|---|---|---|---|
| Klarna | Live — 2.5★, 101 reviews; on-site messaging widget only, the Klarna payment method is enabled in Payments settings | Free to install; Klarna's merchant fees sit in a separate merchant agreement and aren't listed on the App Store (verified Sep 2026) | European markets that Shop Pay Installments doesn't reach |
| Afterpay | Live — 3.1★, 50 reviews; on-site messaging widget only; the same developer lists a near-identical Clearpay messaging app | Free; single plan with no paid tiers; merchant fees sit outside App Store billing (verified Sep 2026) | Australia and New Zealand, Afterpay's home markets |
| Shop Pay Installments | Native — First-party Shopify checkout feature inside Shopify Payments; Affirm is the named partner; no App Store listing | No activation cost; the merchant fee isn't published on Shopify's help pages; shoppers get interest-free plans of 2 or 4 payments every two weeks or monthly up to 12 months, and financing up to 24 months at 0–36% APR (verified Sep 2026) | Any eligible store in the US, Canada or UK on Shopify Payments with Shop Pay active |
The Build Path
- The WAIT lane: Shop Pay Installments: Activate Shopify Payments and Shop Pay, then confirm Shop Pay Installments is on. Eligible stores in the US, Canada and UK; orders from $35 to $30,000 USD/CAD or £50 to £30,000 inclusive of discounts, shipping and taxes; gift cards and subscriptions excluded (verified Sep 2026).
- Add Klarna or Afterpay for one named reason: A market Shop Pay Installments doesn't serve, a gateway that isn't Shopify Payments, or a shopper base with proven affinity. Enable the payment method in Payments settings, install the free messaging app on product pages only, and A/B test before it goes sitewide.
- One installment line in the theme: A single theme block you control renders the installment message under the price, instead of two or three vendor widgets stacked beneath the buy button.
- The only custom-adjacent lane: merchant-financed deposits: Deposit-and-balance for pre-orders and made-to-order goods. You carry the receivable, nobody underwrites the shopper, and it isn't BNPL; it fits a narrow set of businesses.
- Effort band
- $0 for Shop Pay Installments and for enabling Klarna or Afterpay; an estimated $2,000–$6,000 for messaging cleanup and a product-page A/B test (Deploi estimate, illustrative); a merchant-financed deposit flow runs an estimated $15,000–$40,000 (Deploi estimate, illustrative), the $10–25K to $25–75K contact-form bands
- Typical timeline
- Same day for Shop Pay Installments; 1–2 weeks to add and test a second provider; 4–8 weeks for a custom deposit flow (Deploi estimate, illustrative)
- Maintenance, honestly
- ~15–20% of build cost per year (Deploi estimate) on any custom deposit flow. Shop Pay Installments carries no upkeep; a provider widget carries one script to re-check after theme updates and a fee agreement to re-read each year.
- What you own — and what you take on
- You own: the checkout configuration, the messaging placement and the order data in Shopify. You take on: nothing on the native lane; a fee agreement, disclosure rules and a widget per provider; the receivable and compliance exposure on a deposit flow.
3-Year Total Cost of Capability
| Buy (app path) | Build (custom path) | |
|---|---|---|
| Year 0 (setup) | $500–$2,000 (widget placement + A/B test) | $0–$1,500 (activation check + one theme block) |
| Years 1–3 (recurring) | ≈$15,000 (illustrative merchant fees at 5% on $100K/yr) | ≈$15,000 (illustrative merchant fees at the same rate) |
| 3-year total | ≈$15,500–$17,000 | ≈$15,000–$16,500 |
- † All figures illustrative samples for the reference scenario — not quotes, not verified pricing.
- † Klarna column: the free messaging app plus an illustrative 5% merchant fee on $100,000 a year of financed orders (illustrative); Klarna's and Afterpay's fees sit in each merchant agreement and aren't published on the App Store (verified Sep 2026).
- † Shop Pay Installments column: no activation cost and an unpublished merchant fee (verified Sep 2026), modeled at the same illustrative 5% so the lines compare like for like; one theme messaging block up front; three-year horizon.
What the Sticker Price Hides
On the buy path
- — Neither Klarna nor Afterpay publishes its merchant fee on the App Store (verified Sep 2026); the rate arrives in the merchant agreement, so negotiate before the widget goes live
- — A second installment widget under the price splits shoppers who already had Shop Pay Installments rather than adding financed orders; A/B test on product pages before it goes sitewide
- — Klarna's listing sits at 2.5★ across 101 reviews (verified Sep 2026); budget time for widget placement and theme fixes
- — Two providers means two disclosure regimes and two scripts on every product page
On the build path
- — Shop Pay Installments requires Shopify Payments and Shop Pay, and reaches only the US, Canada and UK (verified Sep 2026); a third-party gateway or another market forfeits it
- — Gift cards and subscription products are excluded (verified Sep 2026), so subscription-heavy stores see fewer eligible orders
- — The merchant fee isn't published on the help pages (verified Sep 2026); read it in your admin's payout detail before you compare providers
What Merchants Say
The recurring theme on the Klarna and Afterpay messaging apps is placement: the widget lands in the wrong spot or duplicates a price line after a theme update, and merchants end up editing Liquid to fix it.
Merchants comparing providers describe the same blind spot: the App Store shows Free on every BNPL listing, while the real cost, the per-transaction fee, only appears once the merchant agreement lands.
If You Change Your Mind Later
If you bought and outgrow it
Leaving Klarna or Afterpay means disabling the payment method, deleting the messaging widget and closing the merchant agreement; no data of yours lives in either app, and in-flight installment plans keep running on the provider's side. Check the agreement's notice period before you switch.
If you built and want out
There's nothing to exit on the native lane: Shop Pay Installments switches off in Payments settings, and orders already financed stay with Affirm. If you add a provider later, the native option keeps running underneath it for eligible shoppers.
When This Answer Changes
We're watching for:
- ▸ Shop Pay Installments expanding beyond the US, Canada and UK (three markets as of September 2026), which would retire the strongest reason for Klarna or Afterpay
- ▸ Shopify publishing the Shop Pay Installments merchant fee, or Klarna or Afterpay publishing theirs, which turns this comparison into arithmetic
- ▸ Regulatory changes to BNPL disclosure or late-fee rules in your markets, which move provider fees and shopper eligibility
Verdict change log:
No changes since first publication (September 2026).
Common Questions
Is Klarna or Afterpay better for a Shopify store?
Klarna is better for a Shopify store selling into European markets, and Afterpay is better for Australia and New Zealand. In the US, Canada and UK, Shop Pay Installments beats both at no activation cost (verified Sep 2026). Both apps are free messaging widgets, and each provider's merchant fee sits in a separate merchant agreement (verified Sep 2026). Klarna's listing rates 2.5★ across 101 reviews and Afterpay's 3.1★ across 50 (verified Sep 2026).
Do I need Klarna or Afterpay if I have Shop Pay Installments?
No, a store with Shop Pay Installments doesn't need Klarna or Afterpay for the US, Canada or UK. The native option covers orders from $35 to $30,000 USD/CAD or £50 to £30,000 at no activation cost (verified Sep 2026). A second widget mostly splits the same shoppers. Add a provider for one named reason: a market outside those three countries, a gateway other than Shopify Payments, or an A/B test that shows incremental financed orders.
What do Klarna and Afterpay cost on Shopify?
Klarna and Afterpay cost nothing to install on Shopify: Klarna's listing shows no paid plan cards and Afterpay's shows a single Free plan (verified Sep 2026). The real cost is the per-transaction merchant fee, set in each provider's separate merchant agreement, not on the listing (verified Sep 2026). Shop Pay Installments also has no activation cost and an unpublished fee (verified Sep 2026). Model an illustrative 5% on financed orders until a rate is signed.
Your Next Steps
If you're going with WAIT(matches your selected profile)
- Confirm Shopify Payments and Shop Pay are active and Shop Pay Installments shows as enabled

- Check that your theme renders one installment line under the price, not a stack of vendor widgets
- Measure financed-order share for 4 weeks as the baseline any second provider must beat
- Diary a re-check if you expand to a market outside the US, Canada and UK
If you're going with BUY
- Pick the provider by market: Klarna for Europe, Afterpay for Australia and New Zealand
- Get the merchant fee and notice period in writing before enabling the payment method
- Install the free messaging app on product pages only and A/B test against a holdout for 4 weeks
- Review disclosure rules for installments advertising in each market
- Keep the widget only if financed orders rise without hurting page speed
