How to Evaluate Your Shortlist
Your business has unique requirements. Before you sign a contract, demand to see a live case study of a store with similar order volume to yours. Do not just look at pretty homepages. Check their mobile checkout flow. Test how fast their search bar functions. If the agency cannot show you how they handled a specific technical roadblock, move on to the next candidate.
I suggest you also look for transparency in their billing. Agencies that provide vague hourly estimates usually create budget overruns. Insist on a fixed-price discovery phase. This phase helps you define exactly what you need before development begins. It protects your capital and sets clear expectations for both sides.
Critical Questions for Your Discovery Call
You need to grill your potential partners. Ask these questions
- Do you have experience with headless commerce migrations?
- How will you maintain site speed once we add our heavy media files?
- What is your protocol for handling third-party app conflicts?
- Can you provide three references from clients you have worked with for more than two years?
If they hesitate on any of these, you have your answer. A great agency will be proud of their long-term partnerships and their ability to keep a site fast after layers of apps are installed. Choose wisely. Your store is your most valuable asset.
