Custom Item description columns in SIM

[leswevocli]

I have decided to use authorize.net SIM API for a project, where client sells service and not a product. From SIM guide I found that item description has 

the following columns

      item, description, qty, taxable, unit price and item total. 

As we are selling only service, we don't need qty, taxable and unit total. 

Is it possible to remove those columns in SIM's Item description? and also is it possible to rename the column titles?

Don't believe so, unless there's some way to fake it using styles. You could, however, integrate with DPM instead of SIM - it uses largely the same mechanics, and you'd have total control over the layout of the form. Downside is you'd need to get an SSL certificate just so your customers aren't too scared to order (the form submits securely to Authorize.net, but if you don't have SSL of your own, it appears to be non-secure when they're filling out their info).
