Although it may be more attractive to hear, companies offering flat fees cannot be genuine. Data Recovery and auto repair services are similar and in case of the latter, as you know, it won’t be possible to offer a flat fee. The car repair professional cannot offer you services on a flat fee simply because he won’t be able to tell you the requirements of your case-which parts he will need and how much time he would have to spend. Similarly, in case of data recovery, it is not quite possible to offer services on a flat fee without analyzing the exact needs.
If, for instance, your case needs only a little repair then the company would charge you more than required. On the other hand, if your case is complicated enough, then the company will have to incur a loss. That is why it is impossible to offer genuine services on a flat fee.
