What we deliver

Our Shopify Integration &
Optimisation Services

From custom Liquid development and app configuration to API connections and storefront performance, we assess your store and implement suitable solutions.

01
Custom Shopify Development

Extend Shopify to Fit Your Business Requirements

Standard Shopify features work well for many stores, but some businesses need more flexibility in how their storefront operates.

BrewingHot helps implement custom Shopify functionality based on your requirements, existing theme and available platform capabilities.

Our custom Shopify development services can include

  • Custom Shopify Liquid development
  • Custom theme sections and blocks
  • Product page functionality
  • Collection page enhancements
  • Custom storefront components
  • Metafields and metaobject implementation
  • Dynamic content and conditional displays
  • Cart interface customisation
  • Custom front-end interactions
  • Theme code modifications
  • Supported third-party API integrations
  • Troubleshooting existing custom code

We first assess the required outcome and existing store architecture. Where standard Shopify features or a supported app can solve the problem more reliably, we’ll consider that approach before recommending a more complex custom solution.

Ideal for: Shopify merchants with specific operational requirements, growing ecommerce brands and agencies handling custom storefront projects.

02
Shopify App Integration

Connect the Apps Your Store Depends On

Shopify stores often rely on a combination of applications for marketing, customer service, merchandising, fulfilment and operations.

BrewingHot helps configure and integrate suitable Shopify apps so they work with your storefront and business requirements.

Depending on your setup, we can assist with

  • Email marketing integrations
  • Product reviews and customer feedback apps
  • Loyalty and rewards applications
  • Subscription and recurring-order apps
  • Search and product-filtering apps
  • Inventory and fulfilment applications
  • Customer support and live chat tools
  • Analytics and tracking integrations
  • Product recommendation tools
  • Forms and customer data capture
  • App-related theme customisation
  • Troubleshooting integration issues

We review app compatibility, configuration requirements and any impact on your theme before implementing changes. Where an app requires a paid plan, special permissions or additional configuration, those requirements should be confirmed before work begins.

Ideal for: Stores that rely on multiple ecommerce tools and agencies that need help implementing or troubleshooting Shopify app integrations.

03
Shopify API Integration and Custom Connections

Connect Shopify With Your Existing Systems

Some businesses need Shopify to exchange data with systems beyond the standard capabilities of their installed apps.

Depending on the available APIs, documentation and permissions, we can assess suitable integration work involving

  • Third-party REST or GraphQL APIs
  • CRM and customer management systems
  • Inventory and fulfilment platforms
  • Product data systems
  • Marketing and analytics platforms
  • External business applications
  • Metafields and metaobjects
  • Supported custom data workflows
  • Existing integration troubleshooting

Our process starts by understanding what information needs to move between systems, which platform owns that information and how frequently updates should occur. We then assess the integration approach, authentication requirements, API limitations and potential error-handling needs. More complex integrations may require a separate technical assessment before scope and delivery expectations can be confirmed.

Ideal for: Established ecommerce businesses, brands with specialised operational workflows and agencies delivering custom Shopify projects.

04
Shopify Speed Optimisation

Investigate Slow Storefronts and Improve Performance

A slow Shopify store can create a frustrating shopping experience, particularly on mobile devices. However, performance issues don’t always have the same cause.

They may come from theme code, large images, unnecessary scripts, third-party apps, embedded content or other factors outside the theme itself.

BrewingHot helps investigate performance issues and implement appropriate improvements based on the evidence available.

Our Shopify speed optimisation services can include

  • Shopify theme performance reviews
  • Identification of unnecessary scripts
  • Image and asset optimisation
  • CSS and JavaScript refinements
  • Review of third-party app overhead
  • Removal of avoidable code duplication
  • Investigation of layout shifts
  • Mobile storefront performance improvements
  • Core Web Vitals investigation
  • Performance checks following development changes
  • Recommendations for issues that cannot be resolved through theme code alone

We prioritise practical changes that address identified issues while preserving important storefront functionality. Performance results depend on the store’s theme, apps, third-party scripts, content, platform constraints and the underlying causes of slowdowns. We don’t promise a specific PageSpeed score or guaranteed ranking improvement.

Ideal for: Shopify merchants experiencing slow pages, brands improving mobile usability and agencies that need technical performance support.

05
Shopify Theme and App Troubleshooting

Resolve Issues Between Your Theme, Apps and Custom Code

A store may work correctly before a theme update, app installation or customisation, only for layouts or functionality to break afterwards.

We can assess suitable Shopify troubleshooting requests involving

  • Theme display problems
  • Liquid errors
  • App-related layout conflicts
  • Broken storefront components
  • Responsive styling issues
  • JavaScript conflicts
  • Cart interface problems
  • Product variant display issues
  • Third-party integration errors
  • Changes following theme updates

We investigate the available evidence, identify likely causes and implement suitable fixes where the issue is within the agreed scope. Some problems originate in third-party applications or external systems and may require assistance from the relevant provider.

Ideal for: Shopify merchants and agencies dealing with unexpected storefront issues after updates, installs or customisation.

How we work

How We Approach Shopify
Integration and Optimisation

Our goal is to solve the underlying problem rather than add complexity unnecessarily.

01

Understand Your Requirements

Tell us what you want to achieve, what’s currently happening and how the issue affects your store or workflow.

For integration work, identify the systems involved and the information that needs to be exchanged. For performance work, provide the affected URLs and any existing test results.

02

Review Your Existing Setup

We assess the relevant theme, apps, custom code, integrations and technical constraints.

This helps identify dependencies and determine which implementation options are appropriate.

03

Confirm the Technical Approach

We clarify the expected outcome, scope, dependencies and any limitations before proceeding.

For complex integrations or performance issues, the first step may be an investigation before the full solution can be defined.

04

Implement the Changes

We work on the agreed task, whether it involves custom Liquid, app configuration, API-related development, theme refinements or performance improvements.

05

Test the Relevant Functionality

Where appropriate, we check the affected storefront components, integrations and user interactions to ensure the changes behave as expected.

06

Review and Continue Improving

You review the work and provide feedback within the agreed scope. Once the task is approved, further supported development requests can continue through your subscription workflow.

Built for agencies and white-label partners

Straight answers

Frequently Asked
Questions

1. What Shopify integration services does BrewingHot provide?

We help with suitable Shopify app integrations, third-party API-related development, custom storefront functionality, theme modifications and troubleshooting. The exact approach depends on your store, the systems involved and their technical capabilities.

2. Can you build custom functionality for Shopify?

Yes. We can assess suitable custom functionality involving Liquid, theme sections, front-end code, metafields, metaobjects and supported integrations. More complex requirements may need additional scoping.

3. Can you integrate Shopify with my CRM or inventory system?

Potentially, depending on the systems, available APIs, authentication requirements and data workflows. Share the platforms involved and the information you need to synchronise so we can assess feasibility.

4. Can you integrate Shopify apps into an existing theme?

Yes, where the app and theme support the required implementation. Some apps require configuration through their own dashboards, while others may need theme changes or custom integration work.

5. Can you fix conflicts between Shopify apps?

We can investigate suitable issues involving app-related layout changes, theme conflicts, JavaScript errors and other storefront problems. If the root cause is within a third-party app, resolution may require the app provider’s involvement.

6. How do you optimise Shopify store speed?

We investigate likely causes, which may include images, scripts, theme code and third-party apps. We then implement suitable improvements and check the affected areas. Results depend on the specific issues and what can be controlled within the storefront.

7. Can you guarantee a 90 or 100 PageSpeed score?

No. PageSpeed results depend on many factors, including the theme, app scripts, third-party services, page content and test conditions. We focus on measurable, practical improvements rather than guaranteeing a particular score.

8. Will speed optimisation improve my Google rankings?

Improving performance can support user experience and contribute to Google’s page experience signals. However, rankings depend on many factors, so no specific ranking improvement can be guaranteed.

9. Can you work on my existing Shopify store without rebuilding it?

Yes. We can assess your existing theme, integrations and custom code and work on suitable improvements without automatically requiring a full redesign.

10. Is Shopify integration and optimisation included in the subscription?

Suitable tasks can be submitted through the Shopify development subscription, subject to its scope and capacity. Complex integrations, extensive debugging or work involving external systems may require separate assessment.

11. Do you offer white-label Shopify development?

Yes. We support agency-focused development arrangements under agreed white-label terms, including appropriate branding, communication and handover expectations.
