How Monos Saved 10+ Hours Monthly with Shopify Checkout Extensibility

Overview

Monos, a Vancouver-based travel and on-the-go brand, sells minimalist luggage across four Shopify Plus stores. Handling checkout updates on four storefronts with checkout.liquid became a drain on time and introduced risk with every release. Facing Black Friday, the team needed a leaner approach.

The Challenge

With just four developers supporting all store fronts, even minor tweaks in checkout.liquid required manual edits in multiple code files. The process included locating the right template, making changes, pushing updates, then rigorous testing. This repeated every month or two, creating a backlog just before peak sales events.

The Solution

Monos upgraded to Shopify’sCheckout Extensibility, replacing fragile code edits with app-based extensions. They leveraged:

• Checkout UI Extensions for custom upsells and insurance add-ons.
• Shopify Functions to apply custom logic without touching Liquid.
• Post-purchase extensions to refine the confirmation page.

Using Shopify.dev docs and the upgrade hub, the team rolled out all four stores within days—well ahead of Black Friday.

Results

Immediately after launch, Monos saw:

• 10+ hours savedper month in development time.
• 50% highercheckout conversion when shoppers used Shop Pay vs guest.
• A consistently2X fastercheckout experience.

Removing the need for repetitive code edits freed the team to focus on growth. Regular checkout updates now happen via the app store, not code merges.

Key Takeaways

• Centralize checkout customization with extensions to eliminate manual code duplication.
• Use Shopify Functions for custom logic without Liquid, reducing risk of breaking templates.
• Deploy across multiple stores simultaneously to cut release time ahead of peak sales.
• Leverage Shop Pay integrations in extensions to boost conversion by up to 50% over guest checkout.
• Choose app-based upsells to add features like shipping insurance without custom coding.
• Adopt the one-page checkout from Shopify’s latest platform for faster transitions and better UX.

Conclusion

By switching to Checkout Extensibility, Monos turned a monthly headache into a click-and-deploy routine. Their small team stays focused on brand and product, while reliable app extensions handle checkout needs automatically.
