You can create all of your suppliers in Simple Salon and then assign them to your products. Once you have done this you will be all set up for stock ordering and the process will work seamlessly.
Go to your Admin page, select the Lists tab, and choose Suppliers from the drop down menu.
Click New, fill out the Supplier Details on the right side panel and Save.
You will now see the supplier will be listed under your suppliers list.
Assigning your Suppliers to your Products
Still in Admin, head across to your Products tab. Under the Brand section, click one of the Brands.
In the Products For (Brand) section, Edit a product and on the right side panel choose the product's supplier from the Supplier drop down menu, and Save.
Now that you have assigned the right supplier to the right product, when you process product orders via Ordering the supplier will be automatically applied to the order form.
You can also enter in a Supplier Code if you have one.
