Comparison Table
Absolute Web
agencyAbsolute Web develops custom Shopify stores and ecommerce experiences for growing brands.
Recurring store maintenance coverage for catalog, merchandising, promotions, and order workflow updates.
Absolute Web fits teams that need more than theme tweaks because it covers storefront implementation, ecommerce redesign, and operational maintenance for ongoing changes. The service scope maps to storefront structure work for Shopify brands and retail teams, plus deeper redesign and platform development for established stores. B2B commerce needs get covered through account-specific product selection and ordering workflows. Ongoing support reduces internal handoffs by handling recurring catalog and merchandising updates.
A tradeoff appears when the project requires highly bespoke, cross-system automation beyond the stated maintenance and integration responsibilities. Absolute Web is a stronger usage situation for stores that need coordinated storefront updates with continuing upkeep, or B2B portal workflows that rely on account rules.
- +Theme and template implementation keeps merchandising structure consistent
- +Redesign scope combines storefront work with platform development support
- +B2B portal capability supports account-specific ordering workflows
- +Ongoing maintenance handles recurring merchandising and order workflow changes
- –Complex multi-system automation needs can exceed the stated maintenance workflow
- –B2B projects require clear account rules to avoid rework

Store operations teams

Absolute Web handles recurring merchandising, promotion, technical catalog updates, and order workflow tasks.
Best for: Fits when retail or B2B teams need ongoing Shopify storefront changes with coordinated development.
We Make Websites
agencyWe Make Websites develops custom Shopify and Shopify Plus stores for established commerce brands.
Structured Shopify Plus delivery support for coordinated storefront releases across multiple change sets.
We Make Websites fits teams that need custom Shopify development for new storefront builds, theme customization, or Shopify migrations where storefront behavior must match planned customer journeys. The delivery approach emphasizes structured implementation of approved designs into theme components, which reduces drift between design intent and production code. For more complex enterprise programs, Shopify Plus strategy work and controlled storefront release support helps keep multiple storefront changes aligned.
A key tradeoff is that projects with heavy emphasis on bespoke backend automation may require tighter scoping for integration scope and rollout sequencing inside the Shopify ecosystem. We Make Websites is a strong choice when the project can be expressed as storefront scope plus defined integration work, and when release stages matter for merchandising updates and catalog changes.
- +Converts approved UI into maintainable theme sections and templates
- +Supports Shopify Plus delivery and controlled storefront releases
- +Handles migrations with planned customer-facing storefront behavior
- +Aligns navigation and merchandising structure for launch readiness
- –Integration-heavy backends need tight scoping for rollout sequencing
- –Complex custom extension work may depend on clear requirements and dependencies

Avex Designs
agencyAvex Designs creates custom Shopify and Shopify Plus storefronts for consumer brands.
Structured conversion delivery that pairs storefront implementation with targeted journey improvements like cart and checkout steps.
Avex Designs is a strong match for custom shopify development work that must connect storefront changes to commerce outcomes, because implementations typically align with cart and checkout workflows. The team’s coverage includes theme section customization using editable sections, blocks, and Liquid templates, which can reduce repeated edits across key storefront pages. For Shopify store redesign projects, Avex Designs can rework page structures and navigation so storefront layouts remain consistent after release.
A practical tradeoff is that deeper checkout and storefront feature delivery usually requires more coordination across internal stakeholders, because acceptance depends on storefront UX requirements and system dependencies. Avex Designs is a good usage situation when a merchant needs custom customer-facing storefront functionality around defined user experience and system requirements, or when redesign work must land as a coherent storefront rebuild rather than fragmented updates.
- +Cart and checkout work maps to defined storefront UX workflows
- +Theme section customization supports maintainable page updates
- +Store redesign efforts cover navigation and page structure rebuild
- +Conversion focused projects align implementation with selected journeys
- –Checkout and storefront features require stronger cross-team requirement alignment

How to Choose the Right Custom Shopify Development
We separate options by how deeply they support custom work in the admin and storefront. Look first at extensibility options like checkout extensibility, then confirm the API automation surface that matches your workflow.
Checkout extensibility options
Why it matters
Checkout extensibility matters when we need custom fields, flows, or logic during purchase. If a provider only supports storefront changes, we risk rework later.
How to check
In a demo, ask what parts of checkout they can modify and what limitations they hit. Look for examples tied to real cart-to-purchase outcomes, not just theme edits.
Integration depth and API surface
Why it matters
Integration depth and API surface determines how much of our process we can automate around Shopify. It also affects how reliably custom shopify development can fit our existing tooling.
How to check
Request a walkthrough of how they connect systems and where data moves. Ask for a sample integration flow and what endpoints or events they rely on.
Admin and governance controls
Why it matters
Admin and governance controls matter when we need safe releases, permissioning, and visibility over changes. Without this, custom work can become hard to manage after launch.
How to check
Ask how they handle change tracking and who can deploy or configure updates. In the admin, try locating where settings live and how rollback or version selection works.
Data model mapping for commerce objects
Why it matters
A clear data model mapping avoids surprises when we customize products, variants, or related entities. It also reduces the chance that automation breaks when catalog structure changes.
How to check
Bring a small sample of your catalog structure and ask them to map it to their approach. Confirm how they handle custom fields, variant logic, and how updates propagate.
Theme version and release workflow
Why it matters
Theme version and release workflow affects how safely we can ship custom theme work. A weak workflow often leads to mismatched assets or last-minute fixes.
How to check
Ask what process they use to stage changes and promote them to production. Have them show how they keep changes aligned across theme versions during iteration.
Automation triggers and event handling
Why it matters
Automation triggers and event handling drive how quickly custom shopify development reacts to real commerce events. Reliability here determines whether our customizations stay consistent.
How to check
Request an example of an event-based automation and how they verify it ran as expected. Ask what they do when an event arrives late or out of order.
Red flags
- They can only do storefront theme work and avoid checkout changes
- They can’t show an end-to-end automation flow tied to real events
- They offer no clear release or rollback workflow for custom changes
Fit by situation
- If we need custom fields or logic during purchase, prioritize checkout extensibility options.
- If our teams rely on systems talking to Shopify, prioritize integration depth and API surface.
- If we ship frequently and must control change risk, prioritize theme version and release workflow.
