The Hidden Costs of DIY Integrations (and How to Avoid Them)

When vendors think about integrations, the first instinct is often to build them in-house. On the surface, this do-it-yourself (DIY) approach seems efficient and cost-effective: your engineers know your product, and you avoid paying for external tools or partners. But the reality is that DIY integrations carry hidden costs—measured in lost time, wasted resources, customer frustration, and missed opportunities.

In this article, we will unpack those hidden costs, highlight the risks for both vendors and consultants, and explain how Tavio helps avoid the DIY trap.

The true cost of DIY

DIY integrations demand significant engineering resources. Every new connector requires design, coding, testing, and deployment, often pulling developers away from core product innovation. The burden does not end there. APIs change constantly, authentication protocols evolve, and security updates are ongoing. That means DIY integrations must be monitored, patched, and re-tested continuously.

According to MuleSoft’s Connectivity Benchmark, 90 percent of IT leaders say integration projects take longer than expected and consume more resources than planned. This drain on developer time can delay feature releases, frustrate product teams, and slow down growth.

The support load is another hidden expense. When a homegrown integration fails, customer success teams absorb the fallout. Tickets spike, SLAs are threatened, and customer confidence erodes. Over time, the “savings” of DIY turn into higher costs and opportunity loss.

Instead of reinventing the wheel, vendors can lean on scalable solutions like the Tavio Platform, which separates integration building from deployment, reducing the ongoing maintenance burden.

Risks and missed opportunities

DIY integrations also expose vendors to risks that go beyond cost.

• Failure and downtime risk. When integrations break, the impact is immediate. According to Atlassian, citing Gartner, the average cost of IT downtime is $5,600 per minute. For many vendors, even short outages create significant financial and reputational damage.
  
• Security exposure. In-house integrations are often rushed to meet demand, leaving gaps in compliance, encryption, or auditability. This puts sensitive data at risk and exposes vendors to regulatory scrutiny.
  
• Missed speed-to-market opportunities. While internal teams struggle to build and maintain one or two integrations, competitors who adopt scalable infrastructure can deploy dozens. This leaves DIY vendors at a disadvantage in competitive sales cycles.
  

Instead of falling behind, vendors can explore Partnerships that accelerate ecosystem expansion and open new revenue channels.

Why consultants care

Consultants are often called in when vendors hit the wall with custom integrations. The problem is that DIY solutions tend to be brittle and one-off, making them hard to scale across clients. Every new customer engagement requires custom work, which slows delivery and reduces margin.

Tavio changes this equation. With the “build once, distribute many” model, consultants can design an integration once and deploy it across multiple clients with minimal rework. Centralized monitoring, intelligent versioning, and a library of ready-made Connectors give consultants leverage to serve more clients at scale. Instead of wrestling with one-off code, they can focus on strategic guidance and client outcomes.

An expert opinion

“Building integrations in-house might look efficient at first, but in reality it diverts resources, slows product innovation, and exposes vendors to risk. The smarter play is to leverage scalable integration infrastructure so you can focus on your core product.”

Putting it into practice

DIY integrations come with hidden costs: engineering hours drained, support teams overwhelmed, customer trust damaged, and competitive opportunities missed. Vendors who avoid these pitfalls position themselves to grow faster, reduce risk, and keep customers longer.

Tavio offers the infrastructure to do just that—empowering vendors and consultants to scale integrations with confidence, without the hidden costs.
