Cole's side
The catalog is not the channel
From the inside, a new listing is one more line in a very long list. What moves a vendor up that list isn't the listing. It's evidence that partners can sell it. Are partners actually buying it? Does it attach to something they already sell? Will the vendor show up with enablement, or expect someone else to do it? With proof, the marketplace works with you. Without it, you're inventory.
Ashley's side
Approval is a starting gun
For a small vendor, approval is the first time someone with real reach has said you're credible enough to sell next to everyone else. That's worth something. The mistake isn't celebrating. It's treating approval as the finish line. Her first 30 days after approval: name one owner for the listing, pick ten partners most likely to buy first and call them yourself, give sellers a one-page reason to bring you in, and decide how direct and marketplace deals get credited before the first conflict.
