Certified BigCommerce Agency vs General Developer: What’s the Real Difference

If you're planning to build, migrate, or scale your eCommerce store on BigCommerce, you might be asking:

Should I hire a general developer or work with a certified BigCommerce agency?

At first glance, both seem capable of launching your online store. But when it comes to long-term performance, platform integrations, and business growth, the difference becomes clear.

This comprehensive guide breaks down what sets certified BigCommerce partners apart from general web developers and why that difference matters more than ever for your eCommerce success.

Why BigCommerce Certification Matters

Certified BigCommerce partners are vetted by the platform. They receive direct training, support, and access to platform updates before the general public. According to BigCommerce's official partner program, certified agencies must meet strict technical and business requirements.

At 1Center, our developers, project managers, and designers go through BigCommerce certification training, and we work on projects that align with BigCommerce's roadmap and architecture.

This certification process ensures that agencies understand:

• BigCommerce API limitations and best practices
• Stencil theme development for optimal performance
• Headless commerce implementation using modern frameworks
• B2B functionality and enterprise features
• Platform roadmap and upcoming changes

Where General Developers Fall Short

General developers may be skilled in coding, but without deep knowledge of BigCommerce platform specifics:

• API Implementation Issues: They might not use Storefront APIs properly, leading to performance problems
• Theme Development Gaps: They may skip setting up Stencil CLI for optimal theme performance
• Workaround Dependencies: They often rely on temporary fixes instead of scalable solutions
• Update Management: They miss platform updates or break functionality during upgrades
• Security Vulnerabilities: Lack of platform-specific security best practices

When Should You Choose a Certified Agency?

Choose a Certified BigCommerce Agency If:
