I would suggest you to continue with this. There is another reason that is done - evaluation is done by engineers and purchase decisions needs finance. What you want to do is move the process upfront where the approvals are in place by the time the trial ends. This is why this is pretty standard practice - keep sending reminders every week and also the day before you are going to charge. I (an engineer) have gotten subscriptions for things that would never have gone through if I had to go through and file a report on why this should be bought. Also, not making a credit card mandatory for sign up will get you non-serious customers. You will need to have infrastructure costs to support a large number of these.
