If you want to use a different supplier but your plan has reached the maximum number of suppliers, you'll first need to deactivate an existing supplier before you can connect the new one.
​
If you want to deactivate a supplier you need to do the following:

1. Delete all products, and wait for this to happen.

2. Look up the supplier on the 'browse supplier' page.

3. Deactivate the supplier by clicking the 'deactivate' button.
