There are 2 scenarios, and both of them are bad.
A) You tell the client that you can solve their problem in 10 minutes.Why it’s bad: the client, having no notion of the time and investment needed to get so efficient, will often balk at being asked to pay “full price for a rushed job”.
B) You tell the client when the problem could be solved in 10-12 days.Why it’s bad: it requires creativity to devise a specific delay and stick with it. It also delays payment, postpones the client’s needs being met, and is just an unnecessary net loss for everybody involved.
Although I said both are bad, I prefer scenario B). Why? Science calls it the “Labor Illusion” People value things more when they (think) they see the work behind them.
In the spirit of “if a tree falls and nobody hears it” – “if the client is unable to see the true value of 10-minute service, and making it seem like it takes longer will make them appreciate it more, is it really an illusion?”

But is that dishonest? I would argue it isn’t. Honesty is the absence of lies, while truthfulness is actively making known the whole truth of the matter. Honesty is a mark of a professional, but truthfulness is mostly a step too far. American Bar Association agrees with this.
If your client respects you enough to pay full price for the 10 minutes, that’s ideal. If not, a little illusion will save you both from wasting time.
And if you don’t like that
I understand that, just beware of myopic clients. Maja Puškarić, a LinkedIn expert and personal branding coach, and I talked about a case where she chose to decline payment for a lot of work rather than be insulted by the client’s “negotiating offer”.
