During our all-important tax season, we have loads more uptime during our peak busy times relative to other providers we used.
Tim can give you the actual savings because he calculated it, on the uptime side. In the middle of tax season, we were down at least 2-3 hours every other week - so you can calculate the cost of that down time at an average of $150 per hour, per employee.
If you are on the fence about hiring Tim, I would say compare apples to apples, not apples to grapes - and that you ultimately get what you pay for. If IT isn’t critical to you then you should stay with the vendor you have now."
