How to Decide If You Should Build vs Buy Your Apps

When organizations evaluate the build vs buy decision, discussions often begin with software requirements and budget considerations. Which capabilities are required? Can an existing platform meet those requirements? Would custom development produce a better result?

A custom application can address a unique business need. An off-the-shelf platform can get teams up and running faster. The best choice depends on what you’re trying to accomplish, how quickly you need results, and whether you have the resources to support the application after launch.

What Does Build vs Buy Mean?

The build vs buy framework helps organizations determine whether they should:

Develop a custom application
Purchase an existing software solution
Combine both approaches

Building means creating software specifically for your organization’s requirements. Internal development teams, consulting partners, or a combination of both may be involved.

Buying means licensing a commercial product and configuring it to support business processes.

In practice, many companies do both. They purchase established software for common business functions and build custom applications where existing products fall short.

Why the Build vs Buy Decision Matters

Most companies are managing a mix of legacy systems, cloud applications, and a growing number of AI tools. Technology leaders are being asked to improve operational efficiency, support growth, strengthen security, and help teams work more effectively.

Those priorities often lead to questions about whether current applications can continue to support business requirements or whether new solutions are needed.

But software is only part of the decision. Build vs buy also affects hiring, implementation timelines, maintenance, security, and AI plans.

Organizations considering custom development should also think about talent availability. According to the U.S. Bureau of Labor Statistics (BLS), employment of software developers, quality assurance analysts, and testers is projected to grow 10% from 2025 to 2035, with about 106,100 openings projected annually.

When Building an Application Makes Sense

Custom development may be worth the additional time and investment when a business has requirements that cannot be addressed effectively through existing software.

Your Processes Are Highly Specialized

Most commercial software is designed around common business needs. When workflows are highly specialized, teams often end up creating workarounds or maintaining manual processes.

Custom software can be built around the way your teams already work, whether that’s driven by operational requirements, compliance obligations, or industry-specific processes.

This is common in industries such as healthcare, manufacturing, logistics, financial services, and life sciences.

The Application Supports a Core Business Function

Some applications support administrative functions. Others directly support customer service, product delivery, revenue generation, or day-to-day operations.

If an application sits at the center of a business process, building may be worth considering. The organization can determine how the application works, how it integrates with other systems, and how it evolves over time.

Existing Software Cannot Meet Requirements

Sometimes a commercial platform checks most of the boxes but misses a few requirements that are essential to the business.

When those gaps require extensive customization or manual workarounds, a custom application may be the better path.

You Have the Team to Support It

Building software is only the first phase of ownership.

Applications require updates, testing, monitoring, security management, user support, and ongoing improvements. Before choosing a build strategy, organizations should evaluate whether they have access to developers, architects, product managers, cybersecurity professionals, and other specialists who can support the application after launch.

The National Institute of Standards and Technology’s (NIST) Secure Software Development Framework recommends integrating secure development practices throughout the software development lifecycle to reduce vulnerabilities and improve software security.

When Buying Software Makes Sense

For many organizations, buying software is the fastest and most practical path forward.

You Need a Solution Quickly

Building an application can take months or years depending on its complexity.

When timelines are tight, buying software can eliminate a significant amount of development work. Teams can focus on deployment, adoption, and process improvements instead of creating a product from scratch.

The Function Is Common Across Most Businesses

Many business functions are largely the same regardless of industry. Payroll, HR, CRM, expense management, and collaboration tools already have established software options.

In those cases, developing a custom application may create additional cost and maintenance responsibilities without delivering a clear operational benefit.

Security Reviews Are a Priority

Security should be part of every build vs buy evaluation.

The Cybersecurity and Infrastructure Security Agency (CISA) recommends reviewing software suppliers’ development practices, cybersecurity transparency, vulnerability management processes, and software supply chain practices during acquisition decisions.

Organizations considering commercial software should understand how vendors manage security and whether those practices align with internal standards.

Internal Teams Are Focused Elsewhere

Technology teams are often responsible for infrastructure, application support, cloud environments, cybersecurity, data management, and AI projects.

Purchasing software can help reduce development workloads when internal resources are already committed to other priorities.

The Real Constraint Isn’t Always Technology

Many build vs buy discussions focus heavily on software features.

Execution deserves equal attention.

Custom applications require ownership, staffing, security oversight, budget commitment, testing processes, and ongoing maintenance. Commercial software still requires implementation, integrations, user training, change management, and administration.

Both approaches require people who can support the technology and help it deliver the intended results.

Before deciding whether to build or buy, organizations should assess whether they have the expertise necessary to implement, maintain, and improve the application over time.

Questions to Ask Before Deciding

Before choosing a direction, leaders should answer several key questions.

How Unique Are Our Requirements?

If an existing platform can satisfy most requirements through configuration, purchasing software may be the simplest option.

If major business requirements cannot be addressed without significant customization, building may make sense.

How Quickly Do We Need Results?

Required delivery dates should influence the decision.

A lengthy development cycle may not align with an immediate business need.

What Will Ownership Look Like Over the Next Several Years?

Initial costs are usually easy to estimate. Ongoing ownership is often harder.

The evaluation should include:

Maintenance
Support
Security
Infrastructure
Integrations
Administrative overhead
Future enhancements

Do We Have Access to the Right Talent?

The right software won’t help if you don’t have the expertise to build, support, and improve it.

Organizations should evaluate access to developers, architects, AI specialists, cybersecurity professionals, and product leaders before committing to a build strategy.

How Will AI Connect to the Application?

Organizations evaluating AI use cases should understand how AI tools will interact with business applications, workflows, and data sources.

Whether building or buying, it’s important to understand how the application fits into planned automation, analytics, and AI efforts.

Why Many Organizations Choose a Hybrid Approach

For many businesses, the answer isn’t completely build or completely buy.

A company might buy a CRM platform while building custom dashboards, workflow automations, customer portals, or AI-powered features around it.

This approach allows organizations to use established software where it makes sense while reserving development resources for requirements that are unique to the business.
