How to Set Up Shop Pay Installments on Shopify

Introduction

Offering flexible payment options is a direct way to increase average order value and reduce cart abandonment. Shop Pay Installments allows customers to split their purchases into manageable payments while you receive the full funds upfront. At Nextools, we focus on helping merchants refine their checkout experience, and HidePay is a key part of that optimization strategy — get HidePay for your store.

This guide provides a detailed look at implementing and managing installments on your store. You will learn about eligibility requirements, technical setup steps, and how to use rules to control when these options appear. By following these steps, you can provide a modern payment experience that fits your business model.

Understanding Shop Pay Installments

Shop Pay Installments is a "buy now, pay later" (BNPL) solution integrated directly into the Shopify ecosystem. It operates through a partnership with Affirm, a leading provider in the installment space. This integration allows your customers to choose between interest-free bi-weekly payments or longer-term monthly installments depending on the order value.

When a customer selects this option, they are evaluated in real-time. If approved, they complete the purchase, and you receive the payment in full, minus the transaction fees. The responsibility for collecting future payments sits with Affirm, meaning you do not take on the risk of credit or collections.

The system is designed to remove friction. Because it is part of Shop Pay, customers who already use the service can check out with a single tap. This speed is a significant advantage over third-party BNPL providers that require customers to leave your site or fill out lengthy external forms. For a merchant-focused overview of HidePay and why controlling payment visibility matters, see our Nextools blog post on HidePay.

Difference Between Pay-in-4 and Monthly Plans

There are two primary ways customers can pay using this service. The first is the "Pay-in-4" model. This splits the total cost into four equal, interest-free payments made every two weeks. This option is typically available for smaller orders and is highly popular for fashion and consumer goods.

The second option involves monthly installments. This is generally used for higher-ticket items, allowing customers to spread the cost over 3, 6, or 12 months. Depending on the merchant's plan and the customer's credit, these might carry an interest rate or be offered at 0% APR. Providing these choices helps customers manage their cash flow, which often leads to larger cart sizes.

Eligibility Requirements

Not every store can activate installments immediately. Shopify has specific criteria based on geography, currency, and the type of products sold.

Supported Countries and Currencies

Currently, Shop Pay Installments is available to merchants in three primary regions:

• United States: You must sell in USD and have a physical presence in the US.
• Canada: You must sell in CAD.
• United Kingdom: You must sell in GBP.

If your store is located outside these regions, or if you primarily sell in other currencies, the option will not appear in your Shopify admin. Even if you use a multi-currency setup, the installments feature only triggers when the customer is checking out in the native currency of the supported region.

Core Store Requirements

Beyond geography, your store must meet several technical and administrative requirements:

1. Shopify Payments: You must have Shopify Payments activated as your primary gateway.
2. Shop Pay: You must have the standard Shop Pay "one-tap" checkout enabled.
3. Account Standing: Your account must be in good standing with no major policy violations or high dispute rates.

Some product categories are restricted by Affirm’s terms of service. This often includes regulated goods like alcohol, tobacco, or certain high-risk financial services. Before attempting to activate the service, ensure your catalog complies with both Shopify’s and Affirm’s acceptable use policies.

Transaction Limits and Costs

Each region has specific price floors and ceilings for installment eligibility. If an order falls outside these ranges, the option will not be presented to the customer.

• United States: Orders between $35 and $30,000 USD are eligible.
• Canada: Orders between $35 and $30,000 CAD are eligible.
• United Kingdom: Orders between £50 and £30,000 GBP are eligible.

These totals include the subtotal, taxes, and shipping costs. If a customer applies a discount code that drops the total below the minimum threshold, the installment option will automatically disappear from the checkout page.

Merchant Fees

Using installments carries a different fee structure than standard credit card processing. Instead of your usual Shopify Payments rate, you are charged a specific percentage for installment transactions. These rates can vary depending on your Shopify plan and the specific installment package you choose.

It is important to review these fees in your Shopify admin under the "Payments" section. While the fees are higher than a standard transaction, the trade-off is often a significant increase in conversion rates. You are not charged a separate fee for Affirm; the cost is bundled into your Shopify transaction fee for those specific orders.

How to Activate Shop Pay Installments

The activation process is handled entirely within your Shopify admin. You do not need to contact Affirm or set up a separate account.

Enabling the Service

1. Log in to your Shopify admin and navigate to Settings.
2. Click on Payments.
3. In the Shopify Payments section, click Manage.
4. Scroll down to the Shop Pay section.
5. Check the box for Shop Pay Installments.
6. Review the terms and conditions and click Save.

Once enabled, Shopify will assess your store. In most cases, the activation is instant. If your store requires a manual review, it may take a few business days for the option to appear at checkout.

Selecting a Payment Package

In some regions, you may have the option to choose between different installment packages. For example, you might choose to offer only interest-free options to your customers, or you might choose a premium package that allows for longer terms and higher limits. Your choice here will impact the transaction fees you pay. Most merchants start with the standard package to gauge customer interest before moving to more advanced configurations.

Optimizing the Checkout Experience

Simply turning on installments is only the first step. To maximize the benefit, you need to ensure the option is shown to the right customers at the right time. This is where HidePay becomes a valuable tool for your store. For protecting margins and validating risky orders, consider pairing payment visibility with a validation app such as CartBlock for order validation.

Controlling Visibility with Rules

There are scenarios where you might want to restrict which payment methods appear. For example, if you sell certain products with very slim margins, the higher transaction fee of an installment plan might not be sustainable. Using HidePay, you can create a rule to hide installments when specific items are in the cart — see the guide on how to hide payment methods for specific products in the HidePay docs.

Another common use case is geography. While Shop Pay Installments handles its own regional visibility, you may want to further customize your checkout for international customers. If you are a UK merchant selling to both the UK and the EU, you might want to prioritize different local payment methods for your French or German customers while keeping installments front and center for your British buyers — learn how to organize payment methods by country or Shopify Market.

Sorting for Better Conversion

The order in which payment methods appear can influence customer choice. If your goal is to push customers toward Shop Pay to take advantage of its high conversion rate, you should ensure it is at the top of the list. We designed our tool to allow you to reorder these options without writing any code. By Sort or Rename Payment Methods, you guide the customer toward the most efficient checkout path.

Key Actions for Optimization:

• Analyze your margins: Identify products where installment fees are too high and use rules to hide them.
• Test your layout: Reorder payment methods to see if putting installments first increases your average order value.
• Rename for clarity: Use the renaming feature to make it clear that "Pay in 4" is an interest-free option, which can improve trust at the final step.

For merchants optimizing both payments and shipping together, our post on the HideSuite bundle explains why combining HidePay and HideShip can simplify multi-condition checkout logic and lower overall friction.

Technical Implementation: Banners and Code

To get the most out of installments, you should inform customers about the option before they reach the checkout. This is done through product page and cart banners. For step-by-step how-tos and other HidePay configuration guides, check the HidePay help docs.

Adding the Product Page Banner

Showing the "starting at $X/month" text near your product price helps customers justify larger purchases. Shopify uses a Liquid filter called payment_terms to generate this automatically.

In many modern Shopify themes, you can add this as a "block" within the product information section of the theme editor. If your theme does not support this natively, you may need to add a small snippet of code to your product-form.liquid or main-product.liquid file. The code looks like this:

{{ form | payment_terms }}

This code must be placed inside the product form tags to ensure it updates correctly when a customer selects a different variant.

Updating the Cart Page

The cart page is the last stop before checkout. Adding a banner here reinforces the availability of installments. Like the product page, this is added by placing the payment_terms filter inside the cart form. This banner typically appears below the subtotal. It helps reduce "sticker shock" by showing the broken-down cost of the entire cart.

Using Shop Pay Installments for POS

If you run a physical retail location, you can offer installments to your in-store customers using Shopify POS. This is currently limited to merchants in the United States.

The In-Store Process

Offering installments at a retail counter is a digital-first experience. When a customer is ready to pay, you select Shop Pay Installments as the payment method on your POS device. The system will then generate a QR code.

The customer scans this code with their smartphone, which opens a secure window on their mobile browser. They complete the application on their own device, ensuring their financial data remains private. Once they are approved and confirm the purchase, your POS device will show the transaction as completed.

Staff Training Tips

Because the customer completes the process on their phone, your staff needs to be ready to explain the steps.

• Ensure staff know the $50 minimum for POS installments.
• Remind staff that customers need a US billing address and a supported debit or credit card.
• Practice the QR code hand-off to ensure a smooth transition from the counter to the customer’s phone.

If you need to hide dynamic checkout buttons (for example, to control express checkout visibility), see the HidePay guide on Hide the Express Checkout with HidePay.

Marketing Best Practices

Shopify provides a Marketing Toolkit specifically for Shop Pay Installments. This includes approved logos, banners, and messaging. Using these assets is important because BNPL services are subject to financial regulations.

Compliance and Disclosures

When you advertise "0% interest" or "Pay in 4," there are legal disclosures that must be visible to the customer. The standard Shopify banners include these disclosures automatically. If you create your own custom graphics, you must ensure you include the required Affirm disclosures. Failure to do so can result in your installments feature being disabled or even legal complications.

Strategic Messaging

Instead of just mentioning installments at checkout, feature them in your top-of-funnel marketing:

• Email Campaigns: Highlight the ability to pay over time in your newsletter.
• Header Bars: Add a "Buy Now, Pay Later with Shop Pay" message to your site-wide announcement bar.
• Social Media: Use the approved assets to show how affordable high-ticket items are when split into payments.

Conclusion

Shop Pay Installments is a powerful tool for Shopify merchants looking to scale. By lowering the barrier to entry for expensive products and offering a frictionless checkout experience, you can significantly improve your store's performance.

To summarize the path forward:

• Verify your eligibility based on region and currency.
• Activate the service within your Shopify Payments settings.
• Add informative banners to your product and cart pages to increase awareness.
• Use HidePay to create rules that protect your margins and tailor the checkout for different customer segments.

If you are ready to take full control of your checkout experience, Try HidePay on Shopify. Combining HidePay with a shipping-focused solution can further reduce unwanted costs — consider HideShip on the Shopify App Store to manage shipping visibility alongside payments.

The most successful stores don't just turn on features; they manage them strategically. Control your checkout and give your customers the flexibility they expect.

FAQ

Why is Shop Pay Installments not appearing on my store?

The most common reasons are geographic restrictions or currency mismatches. Your store must be in the US, Canada, or the UK, and the customer must be shopping in the local currency (USD, CAD, or GBP). Additionally, ensure that both Shopify Payments and the standard Shop Pay are active in your settings.

What are the fees for using Shop Pay Installments?

Fees vary depending on your Shopify plan and the specific installment package you select. These fees replace your standard credit card processing rate for those transactions. You can view your current rates by going to the Payments section of your Shopify admin and clicking "Manage" on Shopify Payments.

Does using installments affect my cash flow?

No, it actually helps it. You are paid the full amount of the order (minus transaction fees) upfront, typically within 1 to 3 business days. You do not have to wait for the customer to complete their installment payments to receive your money, as Affirm handles the collection process.

Can I hide installments for specific low-priced items?

Yes. While Shopify has a built-in minimum (such as $35 or £50), you can use HidePay to set custom rules. This allows you to hide installments for specific products, collections, or customer tags, giving you total control over when this payment option is presented. For step-by-step setup, see the HidePay guide on how to hide payment methods for specific products.
