The single biggest mistake brands make is hiring an agency to be an order taker instead of a true strategic partner. It’s easy to fall into the trap of thinking you have the perfect plan and just need hands to execute it. The problem is, this completely neutralizes the value of an outside expert. You’re paying for expertise you’re explicitly telling them not to use. As agency owner Kelly Vaughn explained on Honest Ecommerce, the most successful brands she sees are the ones who know their goals but are open about needing help with the 'how.' You fix this by looking for a partner who can take your ideas and help you grow the business, not just someone to execute on what you want.
Another common misstep is letting a technology vendor introduce you to an agency. This usually happens when you’re evaluating a big software purchase, like a new ecommerce platform, and the salesperson offers a warm intro to a 'certified' agency partner. It feels safe and efficient, but it’s a trap. As the hosts of Future Commerce pointed out in their episode "The Battle for Originality," you're just inheriting the technology company's bias. The agency is incentivized to validate the tech, not to give you an impartial analysis of whether it’s the right solution for your business in the first place. You can avoid this entirely by having established a relationship with your agency first, letting them guide your tech stack decisions based on your business needs, not their partner roster.
A related mistake is hiring an agency that views every problem through the lens of its own specialty. On one Future Commerce episode, the hosts use a great analogy: a carpenter will try to solve every problem with woodwork. The same is true for agencies. A development shop will try to code its way out of every problem, and a performance marketing agency will always prescribe more ad spend. This happens because brands often diagnose their own problem and seek out a specialist for that fix, instead of presenting the business challenge and asking for a diagnosis. The cost is significant, you might end up with a custom-coded solution for a problem an off-the-shelf app could have fixed. As Nate Gunn of Wild Bird mentioned on The Bottom Line, you have to find partners that are more niche to your actual needs.
Finally, many brands bring a project mindset to an agency search when they should be looking for a program. A project has a start and end, and the agency is just a temporary resource. A program, which Jon Reily advocates for on Future Commerce, is about transforming the business, with the agency as a long-term partner in that evolution. It's the difference between asking 'can you build this landing page?' and 'how can we improve our conversion rate over the next year?'. Finding an agency that sees your success as their success is what a genuine partnership is all about.
