For the one's that are self-employed...
I wonder how you charge your clients for windows re-installation and backup/restore of their data.
I find this process to take AT LEAST 2.5 hour if done properly with all the office/utils/updates and such.
I'm asking this, Because sometimes it takes more than an hour just to copy the clients data (If he have multimedia files, Or you decide to clone his primary drive to be on the safe side).
I find it sometime not comfortable to charge the client for all the work I done, Since I charge by the hour.
I had this client which I've needed to install 2 new computers at his office 2 days ago.
I approximate the install/backup work of the 2 computers for a total of 7 hours, And because there was a problem with his office router while I was there, And because I was asked to update some software on other computers, I spent there a total of 12 hours..., Now 12 hours and 7 hours come to something like a 300$ difference in total cost....
What I did is, I've suggested the client to buy a bank of 10 hours when he gets a 15$ discount, And then He will pay less than actual cost.
But what do you do when things takes much longer than you've planned, And there wasn't any other faster way to get the job done ?
