Hello.

With my upcoming computer repair business, I will have some unique marketing strategies in place.

I hope to offer free initial analysis. Included with that is the policy that stipulates that we will not charge our clients until an issue is resolved.

What do you folks suggest I do to secure any money that we deserve once a problem is fixed?

What can stop a person from saying that a problem isn’t fixed, even though we may consider it fixed?

Hmm, that is a gray area in determining what constitues "fixed", and when making an offer like that (which is good initial marketing) it's pretty much fixed when the customer is satisfied.

After you make your free analysis, give the customer a quote of how much you think it'll cost to repair it based on supplies and time. Then, with their approval, go about the repair, and hopefully your quote was correct and the transaction runs smoothly.
