BigCommerce is a powerful platform for building and growing eCommerce stores. But to get the most out of it, you may need custom apps or integrations. That’s where BigCommerce app developers come in. Whether you’re building from scratch or improving your current setup, working with experienced developers can help your business scale.

However, many store owners make mistakes that cost them time, money, and missed opportunities. In this blog, we’ll walk you through the top 10 mistakes to avoid when working with BigCommerce app developers—so your project stays on track.

1. Not Defining Clear Requirements

One of the biggest mistakes is jumping into development without clearly defining what you need. Be specific about your goals, features, budget, and timeline. This helps BigCommerce app developers understand your vision and deliver what you actually want.

Tip: Create a simple document outlining the functionality you need and any specific challenges you're facing.

2. Choosing the Cheapest Option

We all want to save money, but hiring the cheapest developer isn’t always the best idea. Low-cost developers may lack the experience or skills needed for complex projects. This can lead to bugs, missed deadlines, or complete rewrites.

Instead, look for BigCommerce app developers USA who offer good value for your budget—not just the lowest price.

3. Ignoring Communication Skills

Great technical skills are important, but so is clear communication. If your developer doesn’t respond quickly or misunderstands your needs, your project could suffer.

Choose BigCommerce app developers who are responsive, ask questions, and provide regular updates.

4. Not Checking Their Portfolio

Would you hire a photographer without seeing their previous work? Probably not. The same goes for developers. Always check their past projects to see if they’ve built apps similar to what you need.

This is especially true if you’re hiring BigCommerce app developers USA for a US-based business. Look for industry experience and relevant case studies.

5. Skipping Contracts and Documentation

Verbal agreements may seem easy, but they can cause trouble later. Always use a written contract that outlines the scope of work, payment terms, deadlines, and ownership rights.

Good big commerce app developers will expect and respect this process. It protects both sides.

6. Failing to Plan for Post-Launch Support

Your app may work perfectly when launched—but what happens when something breaks or needs updating? Many store owners forget to plan for long-term support and maintenance.

Before hiring, ask the big commerce app developers if they offer post-launch support, bug fixes, or updates. It’s better to be safe than sorry.

7. Not Asking About Testing and Quality Assurance

Even the best developers can make mistakes. That’s why testing is essential. Don’t assume that everything will work perfectly right away.

Make sure your BigCommerce app developers have a clear QA process. Ask them how they test the app before going live and whether they offer a testing phase for you to try it out.

8. Underestimating Timelines

Building or customizing an app can take time—especially if it’s complex. Some clients expect results in a week, which often leads to disappointment.

A professional team of big commerce app developers will give you a realistic timeline. Trust their judgment and plan ahead for delays or changes.

9. Overloading the App with Features

It’s tempting to ask for every possible feature from the start. But too many features can slow down development, increase bugs, and confuse your users.

Instead, work with your BigCommerce app developers to prioritize the most important features first. You can always add more later.

10. Hiring Developers with No BigCommerce Experience

BigCommerce has its own system, tools, and limitations. Hiring general developers who’ve never worked with BigCommerce can lead to poor results or rework.

Always choose big commerce app developers who have proven experience on the platform. Better yet, go with BigCommerce app developers USA if you need someone who understands local market needs and business practices.

Final Thoughts

Working with the right BigCommerce app developers can make your store more powerful, scalable, and user-friendly. But making the wrong choices—or skipping important steps—can set your project back.

To avoid wasted time and frustration, focus on clear communication, realistic expectations, and experienced professionals. Especially for US-based businesses, hiring BigCommerce app developers USA ensures smoother collaboration and better results.

Avoid these common mistakes, and you’ll be well on your way to launching a successful BigCommerce app that helps your business grow.
