Short answer
Of course, but not on the Free Plan.
Here are the relevant quotes from our Terms of Service:
One person or legal entity may not maintain or use more than one Free Account. You must use a single Account for all monitors you manage through the Service. Using multiple Free Accounts (which allow only one monitor to be managed) to manage multiple monitors is not allowed.
If you use the Service to serve your own customers, you are obliged to inform Flipnode about the services you provide using the Service and to whom you provide them, along with any other information Flipnode may request. You may be asked to sign a partnership agreement to continue your business as above.
The Terms of Service apply in whole to (i) the Account Holder, (ii) users the Account Holder has provided access to the Account, and (iii) end-customers and end-users that may receive services through the Service indirectly by a 3rd Party acting as a Reseller or Partner.
Essentially, what that means is that you are very welcome to provide Yodeck-based services to your customers, but they must be on a paid account, even if they only use 1 Monitor. To do that, there are two options:
You (or your customer) should subscribe to the Monthly or Annual Plan for 1 (or more) screens using a credit card, as if the customer were buying directly from us.
You can contact us and get a Reseller Account (or White Label), which will allow you to resell the service to your customers. We will bill you (through an invoice), and you will bill your customers.
