I've spent most of my career working with B2C companies. B2B was just a couple of projects here and there — until last year, when I joined a supply chain analytics company as a Product Designer.
One of my responsibilities is conducting user interviews. That alone has been one of the biggest learning curves of my career. Here's what I wish someone had told me before I started.
Your users are not excited about the product.
They're using it because their job requires it. That changes everything. You're not designing for delight — you're designing to get out of their way. Speed, clarity, and predictability. That's it.
The person who buys the product is rarely the person who uses it.
This one took me a while. In B2B there's almost always a gap between who made the purchase decision and who sits with the interface every single day. You have to design for the user — but you also need to understand the buyer. They're different people with different needs, and you'll have to navigate both at the same time.
Complexity isn't always a design failure.
How many times have you heard "simplify the process, reduce the clicks"? Sometimes the domain is just complex. Supply chain, finance, operations — these aren't simple problems. The job isn't to make it look simple. It's to make the complexity manageable. There's a real difference between those two things.
Users will teach you a vocabulary you didn't know you needed.
In my first user interviews I kept using the wrong words. Not wrong as in incorrect — wrong as in not how they think. B2B users have mental models built from years inside their industry. Learn their language before you try to design for their problems.
"Good enough" ships. Perfect doesn't.
B2B products live inside businesses that have deadlines, integrations, and real operational pressure. You will make peace with imperfection faster than you expect. That's not a failure of craft — it's the job.
If you're just starting in B2B, I hope this saves you at least one painful redesign. Still learning. Still iterating. That's B2B.
