Just because you can build it does not mean you should
There is a question I have been asked a lot recently:
Will AI replace Shopify agencies?
I usually have two answers.
The first is: not really.
The second is: not yet, but we are entering a new cycle.
Both answers can be true at the same time.
AI tools are genuinely impressive. They have already made development faster, research faster, documentation easier, and problem-solving more efficient. In some cases, they can take a task that would previously require a senior developer and make it accessible to someone with very little technical experience.
That is not a small shift.
But the idea that this removes the need for ecommerce agencies, Shopify developers, or technical partners misunderstands where the real value sits.
The hard part of ecommerce development has never just been typing code line by line.
That is the blue-collar part of coding.
Important, yes. Skilled, yes. But still only one part of the job.
The harder part is understanding the business, designing the right solution, and making sure the technology supports the wider operation.
AI is changing the work. It is not removing the work.
AI is very good at building in isolation
AI is excellent when the task is isolated.
Ask it to write a small function, generate a section of code, explain an error, document a process, or create a proof of concept, and it can be incredibly useful.
This is where we get a lot of value from AI as an ecommerce agency.
It helps us move faster. It reduces repetitive development work. It gives us more time to focus on the parts of the job that require judgment.
That includes:
-
Understanding business requirements
-
Translating operational rules into technical logic
-
Planning how a feature should work across the full customer journey
-
Thinking through edge cases
-
Considering how the solution affects the theme, apps, checkout, ERP, fulfilment, reporting, and future maintainability
This is where the agency role becomes more strategic, not less relevant.
AI can help build the technology.
But someone still needs to decide what should be built, why it should be built, and how it should fit into the wider ecommerce system.
The real value is solution design
For Shopify and ecommerce projects, the most important work often happens before development starts.
A business may say:
“We need a custom discount.”
But that can mean ten different things.
Does it need to work across markets?
Does it apply before or after other discounts?
Does it need to respect customer tags?
Does it affect wholesale customers?
Does it need to show messaging on the cart page?
Does it need to work with subscriptions, bundles, gift cards, loyalty points, or free shipping logic?
The code is only the output.
The real work is understanding the rule, the customer experience, the operational requirement, and the platform constraints.
This is where AI still needs strong human direction.
It can produce code quickly, but speed is not the same as quality. A technically functional answer can still be the wrong solution if it does not account for the business context.
We are entering the AI development cycle
The second part of my answer is where things get more interesting.
I think we are at the start of an AI cycle.
Right now, every man and his dog is experimenting with AI tools. People are building things they never would have attempted before.
That is exciting.
Someone with a marketing background and no technical experience can now generate a Shopify function, a custom section, a script, or an app concept. In some cases, it works well enough.
That creates a short-term drop in certain types of agency work.
Tasks that used to require a developer may now be handled internally. Some brands will choose to experiment before bringing in external help. Some marketing managers, ecommerce managers, or founders will use AI to patch together solutions.
In the short term, that feels efficient.
But then the second phase starts.
The Frankenstein codebase problem
The issue is not usually the first AI-generated solution.
The issue is the fifth, tenth, or twentieth.
You get away with it once.
You get away with it twice.
You get away with it three times.
Then the store slowly becomes a Frankenstein of random snippets, theme edits, app workarounds, custom logic, and AI-generated patches that no one fully understands.
This is especially dangerous in Shopify.
A Shopify store is rarely just a website. It often has third-party apps, fulfilment logic, inventory rules, ERP integrations, analytics, email marketing, search, merchandising, checkout rules, and market-specific behaviour all touching the same customer journey.
A small change in one area can affect another.
We have already seen clients enter this phase.
One business came to us with a codebase that had become so messy that almost any modification risked breaking the site. Their team had been able to make short-term changes, but over time those changes created a system that was difficult to manage, difficult to debug, and risky to improve.
That is the next phase of the AI cycle.
First, businesses realise they can build more themselves.
Then, later, they realise that building is not the same as maintaining a healthy ecommerce system.
Just because you can build it does not mean you should
There is also a resource question.
A business owner can paint their own house.
It might get the job done.
It might even look fine from a distance.
But it will probably take longer, the finish may not be as good, and if something goes wrong, they may end up paying a professional to fix it anyway.
The same applies to AI-generated ecommerce work.
Just because a marketing manager can use AI to build a custom Shopify feature does not mean that is the best use of their time.
Should your marketing manager be building an AI-generated app, or should they be focused on marketing?
Should your ecommerce manager be debugging theme logic, or should they be improving merchandising, campaigns, product content, and conversion?
AI can reduce the barrier to entry, but it does not remove the cost of time, context, quality control, or long-term maintainability.
What this means for Shopify agencies
AI will absolutely change the agency model.
Agencies that simply execute tickets without much strategic thinking may find it harder to justify their value. If the only value is typing code, AI will put pressure on that.
But strong ecommerce agencies should become more valuable.
The role shifts from “we build what you ask for” to “we help you work out what should be built, how it should work, and how to implement it properly.”
That means more emphasis on:
-
Discovery
-
Technical planning
-
UX and conversion strategy
-
Systems thinking
-
QA and testing
-
Platform architecture
-
Maintainability
-
Operational understanding
-
Knowing when not to build something
In a world where AI makes it easier to create more technology, judgment becomes more important.
The future is not AI versus agencies
The future is not AI replacing ecommerce agencies.
It is AI separating agencies that only execute from agencies that can think.
The best agencies will use AI heavily. They will be faster because of it. They will use it to remove repetitive work, speed up development, improve documentation, and explore ideas more efficiently.
But the value will still come from the thinking around the tool.
For ecommerce brands, the question should not be:
“Can AI build this?”
The better question is:
“Should this be built, and if so, what is the right way to build it?”
That is where AI still needs human judgment.
And for Shopify stores, especially stores with serious revenue, complex operations, or multiple systems involved, that judgment matters more than ever.
