Frequently Asked Questions

We work with Shopify’s latest extension framework to add logic specific to your business. From custom validations to dynamic pricing rules, we build solutions aligned with Shopify Plus checkout limitations.

A Shopify checkout extension allows us to add custom features or logic at checkout. It uses Shopify’s UI components to extend functionality like offers, inputs, validations, or dynamic content during the checkout process.

Most projects take between 3 to 6 weeks. The timeline depends on feature scope, Shopify Plus setup, required validations, and any third-party integrations involved in the checkout flow.

Pricing varies based on complexity, required custom logic, API dependencies, and post-checkout workflows. After understanding your needs, we share a detailed quote with scope, milestones, and development phases.

We begin by gathering use cases, then create a scope document. Once approved, our team codes the extension, runs staged testing, and handles Shopify Plus deployment without affecting your current checkout.

We use checkout UI extensions to insert fields or components within the checkout. However, layout changes are subject to Shopify’s rules. We adapt features within those guidelines to fit your brand.

We keep extensions lightweight, use Shopify’s recommended libraries, and test across devices to maintain fast checkout performance. All logic is optimized to run without affecting the core checkout experience.

Yes. We can build logic that pulls active discounts or promotions and displays them at checkout. These can be shown based on cart value, user tags, or selected shipping methods.

Yes. We’ve built checkout extensions that support multilingual content, country-specific rules, and regional promotions. Our solutions work well for global stores managing multiple currencies or localized user experiences.

We monitor Shopify's changelogs and API updates. If your extension is impacted, we adapt the code accordingly and test to maintain compatibility without disrupting the checkout or payment flow.

You can contact us with your requirements. We’ll schedule a discovery session, define the use cases, and share a proposal with scope, pricing, and timeline tailored to your Shopify Plus setup.

We can pass checkout data to analytics platforms, CRMs, or ERPs via secure endpoints. This helps track conversions, abandoned checkouts, or segment user behavior based on checkout actions.

We test every function in staging, covering inputs, mobile compatibility, discount rules, and edge cases. You review everything before we publish the extension to your live Shopify Plus store.
