The Client Selection tool is an excellent feature to utilize which will save you a lot of time and the items and their respective colors will be chosen using this interface.
Instructions:
Once you have created a store, you can take advantage of this tool and better prepare for the product creation. Go to Stores, Select the store and then select Products on the left. You will see at the top, Clients selections tool and you can then click the button which will copy a link to your clipboard. Move to a new tab in your browser and paste the link just copied.
STEP 3 - Copy Link
When you click the link, you will be in an end-user catalog priced with a 40% margin - your potential sell price to your customer in the store.
STEP 4 - Search and select products one by one with the + button. Choose as many as you like, but remember your store subscription will limit you based on the plan chosen.
STEP 5 - View selected products at anytime in the cart. The link can be shared with anyone who would like to collaborate. Comments are a nice feature to allow special instructions to be added to products to assist in building them.
After products are added to this list, they will appear after refreshing in the Client List section where you first copied the link!
