Native capability
Use existing Shopify features when they meet the operating rules.
What we check
Identify the exact gap before adding another dependency.
Shopify App Development
Build an app when the business case is clear.
Explore a custom Shopify integration or app only after the requirement, data access and maintenance commitment are understood.
Prices cover the listed scope. Additional work and external costs are quoted separately.
Build or buySolve the workflow.
Solve the workflow.
Choose the right way to deliver it.
We start with the operational gap, the people using the workflow and the systems it touches. Custom development follows a clear comparison of the available routes.
Existing app
Assess a suitable app against the required features, costs and data access.
What we check
Test the important edge cases with representative records.
Custom workflow
Build around a defined integration or behaviour that the other routes cannot reasonably provide.
What we check
Agree hosting, permissions, error handling and maintenance ownership.
| Route | Typical audience | What we establish |
|---|---|---|
| Custom distribution | A specific store or eligible Plus organisation. | Allowed installations, required access and the operating owner. |
| Public distribution | A product for multiple merchants. | App review, onboarding, billing needs and ongoing merchant support. |
A working integration also needs to handle failure.
We include checks for signed requests, minimum required permissions, duplicate events and failed deliveries. New public apps must use the GraphQL Admin API, and App Store approval remains a separate Shopify review.
Shopify App Development
What we’ll deliver.
Validate and build one Shopify app workflow with one backend integration and an explicit operating handover.
- Existing apps cannot meet a specific workflow.
- You need clarity on authentication, permissions and platform limits.
- Ongoing maintenance must be part of the decision.
Confirm that custom work is needed
Compare native features and existing app options against the merchant’s workflow.
How we check it
Record the gap, distribution needs and the agreed build/buy decision.
Specify data and permissions
Define the authorised data, event flow, integration and failure behaviour.
How we check it
Confirm required platform capabilities and keep access limited to the agreed purpose.
Build and validate the workflow
Implement the approved behaviour and run fifteen acceptance scenarios.
How we check it
Cover authorised access, invalid input, duplicate actions and integration failures.
Prepare the operating handover
Document source, deployment, configuration and support ownership.
How we check it
Check the release/rollback instructions and record the thirty-day defect correction window.
Your handover
Requirements and permission map, fifteen-scenario test record, source/deployment handover and maintenance responsibilities.
Included scope and boundaries
- 1 merchant workflow
- requirements and build/buy decision
- permission/data map
- one backend integration
- 15 acceptance scenarios
- repository/deployment handover and 30-day defect window
Outside this scope: Guaranteed public-app approval, extensive billing systems, multi-tenant platform and unknown API work
Scope and investment
Plan the work and the budget together.
$5,000 – $12,000 / scoped custom app
6–10 weeks after feasibility review
Additional costs
Discovery $750 – $1,500; hosting/support separate
What changes the cost?
Distribution, permissions, hosting and integration requirements shape the quote. Agree a store-specific or multi-merchant application during discovery.
Working with your budget
If the full scope is beyond your budget, we’ll prioritise the most useful work and agree a smaller first phase with you.
What we need from you
- Workflow gap
- stores/users
- existing app alternatives
Share what is available. We’ll identify any missing access or inputs during scoping.
Published prices apply to the listed scope. Deliverables, timing, revisions and external costs are confirmed before work starts.

A custom app acceptance plan
An illustrative delivery approach to help you review the scope. This is a planning example, not a client case study.
| Stage | Example work | Acceptance or decision |
|---|---|---|
| Core task | An authorised merchant starts the agreed store workflow. | Check role, required access and input validation. |
| Integration | Send the agreed fields to one external system and record the outcome. | Handle retries and duplicate requests safely. |
| Operations | Document configuration, deployment and support responsibilities. | Review access removal, logs and the release/rollback process. |

Before you decide
Questions worth asking.
Should this be an app, and can your team maintain it?
Begin by checking whether a native feature, suitable existing app or integration can meet the requirement. The proposed custom-app scope covers one workflow and one integration. A store-specific app and a product distributed to many merchants have different delivery and support needs; distribution must be decided during discovery.
Who owns and operates the app?
Define source-code handover, hosting, secrets, permissions and the support owner in the agreement. The starting scope includes a thirty-day defect correction window; ongoing hosting and maintenance are additional.
What should a working demonstration prove?
A representative user can complete the workflow with the required permissions, errors are visible and repeat requests do not cause duplicate actions. Installation, access changes and removal should be considered for the chosen distribution model.
What is the starting budget and what is separate?
$5,000 – $12,000 / scoped custom app. Discovery $750 – $1,500; hosting/support separate These are published USD prices. The written quote must state the complete cost, payment schedule and applicable taxes.
When can the work begin and what do you need from me?
6–10 weeks after feasibility review. To scope the work, prepare: Workflow gap; stores/users; existing app alternatives. The schedule starts after the required access, inputs and approvals are ready.
How are revisions, extra work and support agreed?
Use the listed deliverables and exclusions as the starting point. The quote must state acceptance checks, review rounds, payment stages, cancellation arrangements and any ongoing support. Requested additions need an agreed cost and schedule before implementation.
