Who This Shopify Plus Service Is Built For
This Shopify Plus subscription development service is designed for brands already on Plus that are not yet using what the tier actually makes available.
Checkout Not Activated
On Shopify Plus, the checkout is open for customisation. Custom steps, fields, disclosures, and upsell blocks. Most Plus stores have not built any of it.
Subscription Pricing Too Complex for Apps
Shopify Functions handles pricing logic that no app supports. Subscriber discounts, volume tiers, delivery conditions, and build-your-own-box rules built natively on Shopify.
Operations Across Too Many Tools
A private app built on the Admin API brings subscriber management, fulfillment routing, and reporting into one place inside the Shopify admin.
Multiple Storefronts Not Connected
Shopify Plus includes a central admin layer for managing multiple stores. Shared data, subscriber syncing, and unified reporting across regions and tiers.
If one or more of these reflect where the store is today, this service is built for you.
What Shopify Plus Unlocks That Standard Shopify Does Not
| Capability | Standard Shopify | Shopify Plus |
|---|---|---|
| Checkout customisation | Locked. No custom components, steps, or fields | Open via Checkout UI Extensions. Custom steps, fields, upsells, and disclosures |
| Custom pricing and discount logic | Limited to native discount rules and public App Store apps. No ability to deploy custom server-side pricing logic | Custom Shopify Functions. Deploy your own server-side discount, shipping, and payment logic with no performance ceiling |
| API rate limits | Standard limits that force batching on high-volume operations | Higher limits built for large subscriber bases and real-time sync |
| Private app capability | Custom apps available, but subject to standard API rate limits and without access to Plus-only APIs | Full Admin API and App Bridge access with Plus-tier rate limits and access to Plus-only APIs |
| Multi-store management | Separate admin login per store | Shopify Organization Admin. One central layer across all stores |
| Subscription checkout disclosures | Cannot display recurring charge terms at checkout steps | Checkout UI Extensions enable compliant disclosure at every step |
If none of these limitations are affecting your operation today, Plus may not be necessary yet. If any one of them is creating friction, this is what Plus solves and what we build.

How We Approach Shopify Plus Projects
Understand the Business and the Gap
We look at what your store currently does and what Plus makes available that is not yet built. Goals, workflows, and existing integrations before any development starts.
Design the Right Architecture
Checkout extensions, Shopify Functions, and private apps each need a different approach. We plan before we build, so nothing creates new dependencies.
Build and Test Carefully
Development runs in stages with proper testing across checkout flows, subscription events, and integration sync. We do not skip this step.
Support and Scale
We help evolve your setup as your subscriber base grows and your operational requirements change.
This approach helps prevent fragile Shopify Plus solutions and costly rework later.

Questions You Might Ask Before Starting Shopify Plus Development
What is Shopify Plus, and do I need it?
Shopify Plus is the enterprise tier of Shopify. The key differences for subscription brands are access to the checkout via Checkout UI Extensions, Shopify Functions for custom pricing and delivery logic, higher API rate limits for complex integrations, and multi-store management. You need it when your subscription model requires a checkout that behaves in a specific way: subscription term disclosures, custom upsell steps, and subscriber-specific pricing at checkout. Or when your integration volume is hitting standard API rate limits. If you are on standard Shopify and none of those limitations apply, Plus may not be necessary yet.
What can Shopify Plus do that standard Shopify cannot?
The three most important capabilities for subscription brands are Checkout UI Extensions, which allow custom components directly in the checkout without third-party scripts; Shopify Functions, which let you write custom pricing, discount, and delivery logic that runs natively on Shopify's infrastructure; and higher API rate limits, which are essential for brands with large subscriber bases or real-time integration requirements. Standard Shopify locks the checkout, limits custom logic to script-based approaches with performance trade-offs, and applies lower API rate limits that force batching on complex operations.
How long does a Shopify Plus checkout extension take to build?
A single focused checkout extension, a subscription disclosure block, a loyalty point display, or a custom field collection step typically takes one to three weeks, depending on the complexity of the data it needs to surface and the integrations it needs to read from. A more complex extension that includes conditional logic, subscription upgrade steps, and dynamic pricing display is typically a three to five-week project. We scope all extension work in detail before starting, and we do not give a timeline before we understand the full requirement.
Can you build Shopify Functions for our subscription discount logic?
Yes. Shopify Functions is one of the most powerful tools Shopify Plus makes available and one of the least used, primarily because it requires a developer who understands the Functions API and how to deploy code to Shopify's infrastructure. We build discount Functions for subscription-specific pricing rules that no app configuration panel supports, delivery method functions that present different shipping options based on subscription tier or product type, and payment customisation Functions that restrict or surface payment methods based on order conditions.
