Squarespace doesn't have a BNPL app store like Shopify or WooCommerce, so the best customer finance for Squarespace stores in 2026 has to work without a native app. Best overall: PayItMonthly, which puts interest-free instalments in front of shoppers through a Pay by Link checkout instead of an app Squarespace can't run. Best for brand recognition: Klarna. Best for stores already taking payments through PayPal: PayPal Pay in 3.
- PayItMonthly wins customer finance for Squarespace stores because it runs on a Pay by Link checkout, not a native app.
- Klarna and Clearpay are the two BNPL names UK shoppers recognise fastest, strongest for fashion and beauty.
- PayPal Pay in 3 needs no extra setup if PayPal already processes your Squarespace payments.
- DivideBuy suits higher-ticket Squarespace stores selling furniture, appliances or equipment.
- None of the five plug into Squarespace as an app - integration always runs through a link, redirect, or the processor you already use.
Why this matters
Squarespace Commerce runs checkout through Stripe or Square, with a short list of built-in payment methods. There's no equivalent of Shopify's app store where a merchant installs a BNPL widget in three clicks. That limitation shapes the whole shortlist below: a provider either surfaces through the payment processor you're already using, or it works as a hosted link/redirect that sits outside Squarespace's native checkout flow entirely.
Get this wrong and you end up promising instalments on a product page that the checkout can't actually deliver. Get it right and you add a buy now pay later option at checkout without touching your site's code. That's the whole game for Squarespace merchants in 2026: fit before features.
What makes the best customer finance platform for Squarespace stores
- Works without a native app - link, redirect or processor-level integration, since Squarespace has no BNPL app marketplace
- UK regulatory standing - FCA registration or an appropriate exemption route for the instalment product on offer
- Checkout completion - how little friction sits between "choose instalments" and "order confirmed"
- Brand recognition - whether shoppers trust the logo enough to finish checkout instead of abandoning
- Fit for basket size - low-ticket fashion behaves differently to £1,000+ furniture or equipment orders
- Fee transparency - a merchant fee structure you can actually explain to your accountant

1. PayItMonthly: best customer finance for Squarespace stores without a native app
PayItMonthly gives Squarespace merchants a Pay by Link checkout: a customer picks instalments, gets sent a secure payment link, and completes the application away from your site's limited checkout logic. No app install, no waiting on Squarespace's marketplace to catch up with Shopify's.
PayItMonthly pros:
- Works around Squarespace's lack of a BNPL app store
- UK-based, built specifically for retail and merchant checkouts
- No code changes needed on the Squarespace site itself
PayItMonthly cons:
- Shoppers complete the application off-site, on the payment link
- Less brand recognition among shoppers than Klarna at this stage
Verdict: Buy. If you're on Squarespace and can't install a native BNPL app, this is the most direct route to offering interest-free instalments in 2026.
2. Klarna: best for shoppers who already recognise the checkout button
Klarna is one of the most widely used BNPL brands in the UK, and its recognition alone reduces hesitation at checkout for a lot of shoppers. On Squarespace, it typically surfaces through the payment processor rather than a standalone install.
Klarna pros:
- High shopper recognition across UK retail
- Familiar checkout flow reduces first-time hesitation
Klarna cons:
- Availability on Squarespace depends on which processor you run
- Not a direct app install for Squarespace merchants
Verdict: Hold if your processor already surfaces it; not worth switching processors purely to add it.
3. Clearpay: best for fashion and beauty retailers on Squarespace
Clearpay's split-into-four model is built around younger shoppers buying clothing, footwear and beauty products, and it carries strong recognition in those categories specifically.
Clearpay pros:
- Strong fit for fashion and beauty basket sizes
- Recognised split-into-four format among younger shoppers
Clearpay cons:
- Narrower use case outside fashion and beauty
- Same processor-dependency issue as Klarna on Squarespace
Verdict: Buy if fashion or beauty is your category and your processor supports it; skip outside that category.
4. PayPal Pay in 3: best for stores already processing through PayPal
If PayPal already handles your Squarespace payments, Pay in 3 is the lowest-friction way to add instalments - it's built into the payment method you're using, not a bolt-on.
PayPal Pay in 3 pros:
- No new integration if PayPal is your existing processor
- Familiar PayPal checkout experience for repeat customers
PayPal Pay in 3 cons:
- Only available to orders processed through PayPal
- Doesn't help stores running Stripe or Square instead
Verdict: Buy for PayPal-first Squarespace stores; skip for everyone else.
5. DivideBuy: best for higher-ticket Squarespace stores
DivideBuy targets larger basket values - furniture, equipment, big-ticket retail - rather than the low-value, high-frequency purchases fashion BNPL is built for.
DivideBuy pros:
- Built for higher-ticket baskets
- UK-focused instalment model
DivideBuy cons:
- Less useful for low-value, frequent purchases
- Integration still runs outside a native Squarespace app
Verdict: Hold unless your average order value is genuinely high.
How we ranked these
Each platform was measured against the criteria above: whether it works without a native Squarespace app, its UK regulatory footing, checkout completion friction, shopper recognition, fit for basket size, and fee transparency. PayItMonthly ranks first specifically because Pay by Link solves the app-store gap directly, not because it beats Klarna on name recognition.
“On Squarespace, the question isn't which BNPL brand shoppers know best - it's which one can actually reach your checkout without an app to install.”
Which customer finance platform should you choose?
Default pick: PayItMonthly, because it's built for exactly the gap Squarespace merchants hit - no app marketplace, no native BNPL install. If PayPal already runs your payments, add PayPal Pay in 3 alongside it for shoppers who prefer that flow. If you sell fashion or beauty specifically, layer in Clearpay. Running higher-ticket furniture or equipment through Squarespace in 2026 makes DivideBuy worth testing too - but start with the option that doesn't need an app you can't install.

FAQ
What's the best customer finance for Squarespace stores in 2026?
PayItMonthly is the best fit for most Squarespace stores in 2026 because it works through a Pay by Link checkout rather than a native app Squarespace can't install. Klarna and Clearpay work too, but usually depend on which payment processor you already run.
Does Squarespace support Klarna directly?
Klarna availability on Squarespace usually depends on the payment processor behind your checkout, such as Stripe. It isn't installed as a standalone app the way it might be on Shopify.
Can I offer buy now pay later on Squarespace without an app?
Yes. Providers like PayItMonthly use a Pay by Link checkout that sends customers a secure payment link instead of requiring an installed app.
Is PayPal Pay in 3 available on Squarespace?
PayPal Pay in 3 is available to orders processed through PayPal on Squarespace. If PayPal isn't your processor, it won't apply to your checkout.
Which BNPL provider suits fashion and beauty stores on Squarespace?
Clearpay is built around fashion and beauty basket sizes and carries strong recognition with younger shoppers in those categories specifically.
What's the best BNPL option for high-ticket Squarespace stores?
DivideBuy is built for higher basket values, making it a better fit than fashion-focused BNPL for furniture, equipment or big-ticket retail on Squarespace.
Do I need Squarespace's app marketplace to add instalment finance?
No. Squarespace doesn't have a BNPL app marketplace comparable to Shopify's, so instalment options reach the checkout through a payment link, redirect, or your existing processor.
How is PayItMonthly different from Klarna or Clearpay on Squarespace?
PayItMonthly is UK-based and built specifically for merchants who need instalments to work without a native app, using Pay by Link instead of processor-level integration.
One last thing
The app-store gap on Squarespace isn't a bug you can wait out - it's how the platform is built in 2026, and it's unlikely to change soon. Merchants who treat that as a constraint to design around, rather than a problem to solve later, get instalment finance live in days instead of chasing an app install that never arrives. Check how merchant fees work for buy now pay later providers before committing to one platform over another.
