Checkout & Inline Cart
Display HSA/FSA eligibility messaging in your cart and checkout pages.
To ensure your customers clearly understand they can use their HSA/FSA funds to pay for eligible products, it’s important to display HSA/FSA eligibility messaging prominently at the top of your inline cart or checkout.
This guide explains why this placement matters and offers best practices to implement it effectively.
Why it matters
Many customers are unaware that:
- Their purchase includes HSA/FSA-eligible products
- They can use their HSA or FSA card just like a credit card with Flex at checkout
By highlighting eligibility early in the purchase journey, specifically in the cart or checkout, you can help:
- Reduce friction and confusion
- Increase trust and perceived value
- Improve conversion rates for eligible product purchases
Best practice: inline cart eligibility messaging
Recommended placement
- Top of the inline cart drawer or page
- Above or near the subtotal section
- Clearly visible before the user initiates checkout
Example message
One or more items in your cart are HSA/FSA eligible! Select Flex at checkout to use your HSA/FSA card.
Design tips
- Use a Flex badge or icon to attract attention
- Display a link to a dedicated landing page or tooltip explaining how HSA/FSA payments work
- Show item-level HSA/FSA eligibility next to applicable line items, when possible
Industry best practices for cart messaging
| Best Practice | Description |
|---|---|
| Be explicit | Use terms like “HSA/FSA card,” “eligible,” and “Flex” to avoid ambiguity |
| Keep it brief | Cart messaging should be 1–2 short lines to avoid clutter |
| Use visual cues | Flex Icons and consistent HSA/FSA branding help reinforce the message |
| Repeat strategically | Reinforce eligibility in product pages, the cart, and during checkout |
Buttons
In addition to messaging, consider adding a button or call-to-action that helps customers checkout using their HSA/FSA funds.
Business impact
Displaying HSA/FSA eligibility in the cart can drive measurable results:
- Higher conversion rates for eligible products
- Increased cart confidence - customers feel empowered when using pre-tax funds
- Lower abandonment rates for health-related items
Implementation notes
- If you’re using Shopify, this messaging can be added via theme customizations to your cart page. You can also add it in the cart-drawer.liquid or cart.liquid files.
- You can optionally use product tags to conditionally display the message only when HSA/FSA-eligible items are present.
Summary
Highlighting HSA/FSA eligibility with Flex at the top of the cart is one of the highest-impact ways to drive awareness and usage. By clearly communicating this benefit, you unlock a powerful incentive for your customers to complete their purchase using funds they’ve already set aside.
