Hello Chris,
There are limits to our multi account plan - for an account on a paid plan that has unlimited listings (which is then the primary account for that plan) you can have two sub accounts which would also have unlimited listings, however they have image hosting limited at 500MB per account; the sub accounts have no associated plan fees when on this plan.
Each account is wholly separate from the others, they each have their own unique log in and dashboard and there is no capacity to share listings or images between accounts. Based on what you have described here, you would need to have more than one primary account to accommodate your eBay accounts.
Please note that to set this up, you do need to contact us as the Multi Account Plan is not shown on the plan selection page. If you would like to try this please go ahead and set your primary account to Elite and set up two other accounts properly associated with the related eBay accounts and let us know the usernames of all of the accounts in a support case and that you are interested in this plan and our support team will be happy to assist you.
- Craig
