Introduction

Common mistakes hiring Ruby on Rails agency can lead to wasted time, higher costs, and poor project results. Whether you are developing a new web application or upgrading an existing platform, avoiding these pitfalls will help ensure your project’s success.

Ruby on Rails is still one of the most reliable frameworks in 2025, but choosing the wrong agency can derail your plans. In this guide, we’ll cover the common mistakes hiring Ruby on Rails agency and how to avoid them effectively.

Not Checking the Agency’s Rails-Specific Experience

Many agencies list Ruby on Rails as one of their capabilities, but their portfolio may be dominated by other technologies.
If Rails projects make up only a small fraction of their work, they might not have deep expertise.

How to Avoid:

  • Ask for Rails-specific case studies.
  • Verify experience with Rails 7 and modern practices like Hotwire, Turbo, and API-only mode.
  • Review their GitHub repositories and open-source contributions.

Overlooking Technical Fit – Common Mistakes Hiring Ruby on Rails Agency

Some agencies specialize in MVPs, while others excel at scaling enterprise-level apps. Choosing one without matching their expertise to your project stage can cause problems.

How to Avoid:

  • Match their skillset to your needs (e.g., scalability, performance optimization, or integrations).
  • Ask how they’ve handled database performance, caching, and background jobs in past projects.

Ignoring Communication and Project Management Style in a Rails Agency

A technically skilled agency can still fail if communication is slow or unclear. Misunderstandings lead to missed deadlines and increased costs.

How to Avoid:

  • Ensure they use transparent project tracking tools (Jira, Trello, Monday.com).
  • Request weekly or bi-weekly status updates.
  • Check if they provide a dedicated project manager.

Focusing Only on Price When Hiring a Ruby on Rails Agency

While budget is important, the cheapest agency may cut corners—resulting in buggy code, missed deadlines, or costly rewrites later.

How to Avoid:

  • Balance cost with quality and proven track record.
  • Consider total cost of ownership, not just initial quotes.
  • Ask for detailed proposals outlining deliverables.

Skipping Client References – Common Mistakes Hiring Ruby on Rails Agency

Relying solely on the agency’s marketing materials is risky. Past client feedback gives you insight into reliability, quality, and professionalism.

How to Avoid:

  • Contact at least two past clients directly.
  • Check Clutch.co, Upwork reviews, or LinkedIn recommendations.
  • Ask about post-launch support and how issues were handled.

Not Defining Clear Scope and Deliverables With a Ruby on Rails Agency

An undefined scope leads to scope creep, cost overruns, and delivery delays.

How to Avoid:

  • Create a detailed scope document before signing a contract.
  • Use a Statement of Work (SOW) to define features, timelines, and responsibilities.
  • Agree on change request procedures in advance.

Overlooking Post-Launch Support From Your Ruby on Rails Agency

Your relationship with the agency shouldn’t end at launch. Without proper maintenance and support, security vulnerabilities and bugs can pile up.

How to Avoid:

  • Ask about ongoing support plans.
  • Ensure they have a process for upgrading Rails versions and dependencies.
  • Clarify response times for critical issues.
