Common Mistakes Businesses Make When Hiring the Right Shopify & Shopify Plus Agency in Boston

• Prioritizing visual design over platform structure often leads to Shopify builds that look polished at launch but struggle to scale once integrations, traffic growth, or operational complexity increase.

• Overlooking how Shopify will integrate with existing systems such as ERP, CRM, or internal tools can create data gaps, manual work, and ongoing inefficiencies after launch.

• Selecting an agency without a defined post-launch support plan leaves teams unprepared for performance tuning, bug fixes, and ongoing improvements required to keep the store stable.

• Underestimating the complexity of Shopify Plus migrations, especially from legacy or enterprise platforms, can result in extended timelines, unexpected costs, and compromised data accuracy.

• Treating the Shopify project as a one-time build instead of a long-term platform limits flexibility and makes future enhancements harder and more expensive to implement.

• Failing to assess how an agency collaborates with internal teams can lead to communication gaps, misaligned expectations, and slower progress during critical development phases.
