The 5 Loudest Signals That It’s Time to Ditch Your Custom Stack

Enterprise commerce leaders are under pressure to move faster, reduce costs, and deliver experiences that scale. Yet many remain locked into custom-built platforms that generate more noise than value.

By noise, we mean the constant distractions that drain resources and cloud decision-making. Endless patches. Fragile infrastructure. Rising costs with no clear return. These are not minor issues. They are alarms signaling that the platform you once trusted is now holding your business back.

You may have grown accustomed to living with the noise. But you do not have to.

Avex and Shopify launched Outgrown the Homegrown to provide a clear, structured pathway for enterprise brands to break free from technical debt and modernize on a platform built for scale. The first step in that journey is identifying the noise.

So what are the loudest signals your custom platform is sending you? 

Technical Debt That Compounds Every Quarter

Technical debt is often spoken about in engineering terms, but its true cost is organizational. Every patch and workaround adds complexity. Over time, systems become so fragile that engineering teams spend more cycles maintaining than innovating. Talent is wasted. Roadmaps slip. Budgets inflate.

For leaders, technical debt should be viewed as compounding interest. Every quarter, it grows heavier, silently eroding the organization’s ability to innovate. And like financial debt, it eventually forces tradeoffs you do not want to make.

The economics reinforce this point. According to research commissioned by Shopify and conducted by a leading independent consulting firm, total cost of ownership on Shopify can be up to 36 percent lower than competitors. That advantage does not come from marginal savings. It comes from eliminating entire categories of expense, including compliance, hosting, and security. Combined with Shopify’s extensive app and partner ecosystem, enterprises gain both flexibility and cost efficiency.

Outgrown the Homegrown ensures the migration retires debt rather than carries it forward, restoring engineering capacity to its rightful role: building the future.

Release Cycles That Kill Momentum In enterprise commerce, time to market is the ultimate measure of competitiveness. It determines whether you set the pace in your category or spend your resources reacting to others who do. When every campaign takes weeks of testing or every product launch is delayed by regression cycles, the business is not just slowed down. It is stalled.

Slow release cycles impose a ceiling on growth. They represent missed revenue, delayed innovation, and lost momentum. And momentum is one of the most valuable assets an organization can have. Once it slips, it is extraordinarily difficult to recover.

Modern platforms like Shopify restore market velocity. Upgrades are managed at the infrastructure level, reducing friction and freeing teams to focus on what creates value. Marketing and product teams gain autonomy through Shopify’s intuitive back-office UI, which enables them to launch products, build promotions, and respond to market opportunities without waiting on the development queue.

Custom stacks reverse this dynamic. They make even simple updates dependent on engineering resources already stretched thin by maintenance tasks. The result is a backlog that grows heavier each quarter while competitors move faster and capture share.

Customer Experience Cracks That Erode Trust

Customer experience is not a soft metric. A failed checkout, a subscription error, or a slow site is more than a technical glitch. To the customer, it signals that the brand cannot be relied upon.

The risk grows when new functionality is introduced. On custom platforms, even small updates can trigger regressions that ripple through the customer journey. Each new feature requires heavy testing, which slows down releases and increases the likelihood of missed issues..

At enterprise scale, these cracks multiply quickly. A small percentage of failed checkouts or subscription errors can translate into millions in lost revenue each year. Beyond the immediate loss, churn rises, retention weakens, and lifetime value erodes. Marketing spend is diluted because new customers are acquired only to replace those lost to experience failures.

quip faced this reality as their custom platform grew more fragile under the weight of new functionality. Customer experience problems were mounting. After replatforming to Shopify, they reduced those cases by 70%. The change did more than eliminate errors. It created confidence to test, launch, and scale new experiences without sacrificing reliability.

Trust is the most valuable currency in commerce. It takes years to build and only moments to break. Leaders who treat customer experience issues as minor defects underestimate their strategic impact. These are not isolated bugs. They are signals that the foundation of loyalty and revenue is under strain.

Rising Costs With No Clear Return

Rising costs are one of the loudest signals that a custom stack has outlived its usefulness. What once seemed efficient begins to drain resources in ways that are both visible and hidden. Infrastructure spend grows as traffic scales. Contractors and specialized support become permanent line items. Even minor updates require significant investment in testing and QA.

The issue is not just high spend, but a misaligned one. At the executive level this is more than a budgeting challenge. It is an opportunity cost at scale. Every million spent on infrastructure or custom upkeep is a million not invested in acquisition, retention, product development, or global expansion.

Shopify changes this equation. In 2024 alone, Shopify invested $1.4 billion in R&D dedicated to continuous platform development. For merchants this translates into direct access to international commerce capabilities, advanced B2B tools, the latest AI-driven features, and faster, more reliable checkout experiences. All of this comes without the burden of carrying development costs internally.

Competitors Moving Faster Than You

Every market opportunity has a window. A new channel, a seasonal surge, or a shift in customer behavior creates value only for the brands that can act quickly enough to seize it.

When competitors are first to launch, they do more than capture early revenue. They set the standard for what customers expect in your category. Once that expectation is established, your brand is no longer competing on equal terms.

Custom stacks amplify this disadvantage. Even minor functionality can take weeks of development, QA, and integration. By the time your team pushes live, the market has already moved forward and the opportunity has passed.

Shopify eliminates that drag. Its unified suite of tools allows merchants to automate repetitive tasks, launch faster, and direct resources toward growth rather than maintenance. That agility produces measurable outcomes: 

• Conversion rates up to 36 percent higher than competitor

• Customer acquisition costs cut by up to 50 percent with Shopify Audiences

• Average order values 15 percent higher with Shop Pay.

The impact compounds. Faster competitors are not only capturing revenue. They are running more experiments, learning more quickly, and scaling ideas while slower organizations are still deploying a single release. Over time, that learning advantage becomes a market advantage that is extremely difficult to close.

Claim Your Quiet

Noise is not harmless background static. It is the drag that slows every release, the cost that inflates every budget, the cracks that weaken every customer relationship. It is what keeps your best talent maintaining the past instead of building the future.
