When importing a product from the marketplace, you'll need to pick a sale price (the price you'll sell the product for). Crowdship can automatically assign a sale price to save time, using the preference set in your Product Settings.
Go here to choose your pricing preferences.
You can either markup your cost, or you can opt to use the suppliers Suggested Retail Price (SRP).
These settings can be overridden at the individual product level, and should be used to speed up product onboarding until you can fine tune your pricing.
