B2B and wholesale
Price list
The price list is the part of a B2B catalog that decides what the buyer pays. It can be a percentage adjustment off the retail price or a fixed price per variant, and both forms can be mixed inside the same catalog.
Also called: pricing, wholesale price list, B2B pricing
The choice between a percentage and a fixed price looks minor and it decides how much maintenance the store costs you every season.
Percentage off retail
A discount applied on top of the retail price. When you raise B2C prices, the wholesale ones move with them. This is what I recommend by default: no list goes stale.
The problem shows up when margin is not uniform. If wholesale pays 40% less in one product family and 25% less in another, a single global percentage does not cover it and you either split the catalog or move to fixed prices.
Fixed price per variant
The price list written by hand, SKU by SKU. It gives total control and it has a cost: every B2C price change has to be replicated here, and if it is not, the wholesale buyer ends up paying more than the retail customer. I have seen that in production more than once.
My rule: percentage by default, fixed price only on the SKUs where the agreement with the customer forces it, and a price review on the calendar. If you mix them, write down somewhere which SKUs are fixed, because inside the admin they do not stand out at a glance.
What a price list is not
It is not the way to give every account its own price without Plus: catalogs are assigned per market, so the list reaches every company in that market. Per-account pricing needs Shopify Plus or a public app.
