Once you have created a product and added an offer or offers for that product you need to make it available to the Assemblies you supply.
First go to the 'Products' section of your account and make sure 'Stock' is selected. Search for the product you would like to make available and make sure the offer is set to 'available'. You can do this by turning the switch on next to the product so it goes green.
Click on the name of the product you would like to make available to an Assembly.
A menu will appear on the right hand side of your screen. On this menu you can select and deselect which Assemblies your product is available for by ticking or unticking the boxes.
To make a product unavailable for all Assemblies simply click the switch to the off position which is grey.
