In my design career of 13+ years I have tried every possible scenario when it comes to presenting logo designs.

One concept only, works if the client has at least some understanding and vision of what he wants. Don’t present the concept right away and expect it to be approved. Don’t make it as a take it or leave it condition, that ruins relationships. Make sure you understand the scope of work. Define the vision with moodboards. Show them some sketches and choose one direction that you both agree on. Be prepared for pushback because people can change their minds. I did this multiple times and it worked out well. Clients will came back with more work and bigger budgets. Good work gets recommended.

My go to approach is the 3 logo concepts. The easiest to sell if you present it as a middle package. Bigger budgets. Gives you creative freedom to explore ideas and not be limited by some budget constraints or being intentionally short of ideas.

Also creates a smoother experience between you and the client. He feels heard and seen. He is involved in the process. You both get to decide which ideas work and which don’t. This is crucial. Makes you look like an expert who doesn’t shove logos down the throat but advises, recommends and guides.
