oh really?

so im not alowed to offer a service?

Yes that is what i am doing, I offer an online service with invoices via email.

so do i list the item with free delivery? as because all handing of this service is done via emails with my customers

Nothing digitally delivered that means email or over the internet.

I see you have already listed your service.

Now im a little confused

I offer a service like a tax agent or lawn mowing company, Customers pay me for the service and i supply that service.

Please look at my ad that i have listed

You can sell a tangible service on eBay. 

The OPs service is a tangible service that is provided remotely.

Electronic delivery is another issue all together.

I am not sure of other policies that may impact on this type of service.

Sorry i think i should give more details

I supply a service for mobile phones

Although the customer can send me there phones for repair as i have done lots of in the past, I dont pysically need there device as all i require is screen shots sent to me via email.

This is far more cost effective and speedy then waiting for there phones to arrive via post.

Because i dont require postage this way i am wondering do i list this service as free postage or Electronic delivery?
