What to Ask Before You Sign
Don’t jump into a contract because of a pretty portfolio. You need to ask hard questions. First, ask them for a list of stores they currently manage. Visit those sites. Are they fast? Do they work on your phone? If they look good but load slowly, walk away.
Second, ask about their internal staffing. Are they outsourcing your work to freelancers, or is there a dedicated team of in-house developers? Outsourcing can lead to fragmented code and security vulnerabilities. You want a team that takes ownership of your store’s architecture.
“Your agency should feel like an extension of your own team. If you feel like they are just reading from a script, find someone else.”
The True Cost of Scaling
Paying an agency is an investment, not an expense. When you hit a million dollars in monthly revenue, a 1% increase in conversion rate is worth ten thousand dollars a month. Think of your agency costs in that context. You aren’t just paying for code; you are paying for the prevention of lost revenue.
I suggest you prioritize agencies that offer long-term support. A one-off project is fine, but a platform like Shopify Plus changes constantly. You need a partner who watches the updates and keeps your store compliant and performant as the platform evolves.
Final Thoughts on Choosing Your Partner
You know your brand better than any agency does. Don’t let them steamroll your vision. Keep a close eye on the project roadmap and insist on regular updates. If a feature feels like it doesn’t align with your customer journey, push back.
Pick an agency that challenges your assumptions. If they agree with everything you say, they aren’t experts; they are just order-takers. The right agency will tell you when a specific feature will hurt your site speed or confuse your users. Trust the ones who are willing to say “no” to save you from your own bad ideas.
