When to Build vs. When to Buy Software: A Practical Guide for Growing Portables Companies

Every growing company eventually faces the same question: Should we build our own software, or should we buy an existing system?

On the surface, building sounds attractive: Total control. Custom workflows. Built specifically for a specific business model.

But the real decision isn’t about preference. It’s about scale, economics, operational risk, and long-term ownership.

For most companies – especially small to mid-sized operational businesses – the smartest move is to buy.

→ The key is to buy the right kind of software.

Let’s break down why.

The Hidden Cost to Build Custom Software

When leaders say, “We’ll just build it internally,” they usually budget for development — not ownership.

Building software is not a one-time project; It’s an ongoing operational commitment.

Here’s what custom software actually requires:

  • Full-time or contract developers
  • Infrastructure and hosting
  • Security and compliance management
  • Maintenance and bug fixes
  • Integrations and API management
  • Documentation and training
  • Support staff
  • Redundancy, uptime monitoring, and backups
  • Ongoing product roadmap planning

Software is never “done.” It evolves. It breaks. It requires updates.

If a company isn’t operating at a revenue level of over $100M (and often significantly higher), building software means they are effectively funding a software company within their business.

That’s not a $30,000 decision. It’s a multi-million-dollar commitment over time.

The $20K–$30K Custom Build Trap

Many small and mid-sized companies are offered “custom systems” in the $20K–$30K range.

Here’s the reality: That price typically buys a prototype, not a long-term solution.

What companies often receive:

  • A minimally viable product
  • Limited scalability
  • Sparse documentation
  • One developer as a single point of failure
  • No dedicated support team
  • Ongoing change orders

Six to eighteen months later, many businesses find themselves:

  • Paying 3–4x the original quote
  • Missing critical features
  • Dependent on one contractor
  • Operating on fragile infrastructure

At that point, a switch is expensive – financially and emotionally. Leaders hesitate to abandon sunk costs, even when operational efficiency suffers.

When Enterprise Software Makes Sense

Large enterprise software providers offer real advantages:

  • Mature infrastructure
  • Strong uptime and security
  • Compliance handled
  • Large support organizations
  • Proven long-term viability

With enterprise software, portable companies buy something that already works at scale, but there are tradeoffs:

  • Limited flexibility
  • Expensive custom development
  • Slower roadmap responsiveness
  • Long support queues
  • Each customer is often just another account number

For standardized workflows and larger budgets, enterprise software can be a safe choice, however companies will need to advocate during implementation to ensure their needs are addressed.

Why Purpose-Built, Industry-Specific Software Often Wins

For many in the portables industry, the best balance is niche, purpose-built software from a stable mid-sized provider.

Not a one-person shop.
Not a faceless enterprise giant.
But a focused company built for unique workflows and needs.

Here’s why this model works:

1. Industry Expertise Reduces Friction

Purpose-built systems understand specific terminology, workflows, compliance realities, and operational constraints.

That reduces:

  • Customization costs
  • Implementation friction
  • Training time
  • Process disruption

Don’t adapt a business to software; use software that is already aligned to meet the unique needs of the portables business model.

2. Shared Development Lowers Long-Term Cost

With internal software builds, the company funds 100% of development.

With niche software, innovation costs are shared across the customer base.

That means:

  • Faster feature releases
  • Continuous improvement
  • Industry-driven enhancements
  • Lower per-customer cost of advancement

Portable and rental businesses that invest in software built for them benefit from collective momentum.

3. Gain Stability Without Bureaucracy

A healthy mid-sized software provider should have:

  • In-house developers
  • Dedicated customer support / customer success
  • Product management and roadmap planning
  • Multiple team members beyond sales
  • Industry credibility

This structure offers both responsiveness and reliability (without enterprise-level rigidity).

Operational Risk: The Question Most Leaders Don’t Ask

Software decisions are not just feature decisions. They are continuity decisions.

Ask the following questions. when making important decisions about software for portable storage, sanitation, containers, trailers, or modular space businesses:

  • Who answers the phone when something breaks at 5 AM?
  • Who patches security vulnerabilities?
  • Who monitors uptime?
  • Who manages backups?
  • Who trains new employees?

A mature software company has entire teams dedicated to these responsibilities.

A custom build typically does not.

Operational risk is often underestimated in build-versus-buy discussions, yet it’s one of the most critical variables.

When Custom Built Software Actually Makes Sense

There are legitimate scenarios where building is strategic:

  • $100M+ enterprise companies
  • Software is a core competitive differentiator
  • Ability and means to hire and retain a full internal development team
  • Off-the-shelf systems cannot support the model

Even then, many large companies choose to buy a strong core platform and layer integrations rather than build from scratch.

The Strategic Framework for Build vs. Buy Decisions

For most small to mid-sized operational companies, the hierarchy often looks like this:

  • Best Option:
    Purpose-built, industry-specific software from a stable mid-sized provider
  • Second Option:
    Large enterprise software (if workflows are standardized and the budget allows)
  • Last Resort:
    Custom build — unless there is enterprise-level scale and technical infrastructure in place

The goal is not just software. The goal is operational leverage, stability, and long-term return.

Choose a Partner, Not Just a Platform

The best software decisions are relational and strategic – not purely technical.

Look for a company that:

  • Understands the portables industry deeply
  • Invests in product evolution
  • Has the operational depth to support growth
  • Builds with customer feedback
  • Views customers as long-term partners

The right system shouldn’t just “run the business.”
It helps operate smarter, reduce friction, and scale confidently.

For growing companies, the right purpose-built platform will outperform a custom build in cost, speed, stability, and long-term ROI.

FAQ: Build vs Buy Software

Should a small business build or buy software?

Most small businesses should buy software rather than build it. Custom software requires ongoing development, security management, infrastructure, and support resources. Unless software is your core product and you have significant internal technical resources, buying a purpose-built platform is usually more cost-effective and less risky.

Building software may make sense if:

  • Your company generates $100M+ in revenue

  • Software is a core competitive advantage

  • Off-the-shelf platforms cannot support your model

  • You can fund a full-time internal development team long-term

Even then, many large companies buy a core system and customize around it.

Common risks include:

  • Underestimated long-term costs

  • Dependency on a single developer

  • Lack of dedicated support infrastructure

  • Security vulnerabilities

  • Scalability limitations

  • Delays in feature development

Software ownership is an ongoing operational commitment — not a one-time expense.

Enterprise software offers strong stability and infrastructure but can lack flexibility and responsiveness. Niche, purpose-built software often provides better industry alignment, faster implementation, and closer partnership — especially for specialized operational businesses.

Purpose-built software is designed specifically for a particular industry or operational model. It reflects real workflows, terminology, compliance needs, and reporting requirements, reducing customization costs and improving adoption.

Look for:

  • Industry expertise

  • In-house development team

  • Dedicated customer support

  • Clear product roadmap

  • Proven customer retention

  • Operational depth beyond sales

Software is a long-term partnership decision, not just a procurement decision.
