You aren't wrong, but you’re underestimating the inertia of $10M+/year B2B distributors. There are thousands of these in traditional sectors (pipe manufacturing, HVAC, etc.) that rely on hyper-localized logistics and century-old workflows.
Buyer pressure will eventually force process updates, but it is a slow burn. The bottleneck is rarely the tech or the partner, it's the internal culture. The software moves fast, but the people deeply integrated into physical infrastructure move 10x slower than you'd expect.
