Under promise and over deliver. Many successful businesses run with that model. It works surprisingly well.
Granted things can happen but if you don't start out with a promise based on the stars aligning you give yourself breathing room. Then if no problems arise you deliver early or on time. People rarely complain about faster service.
And honest communication is key. The truth is usually much easier to keep track of than multiple stories. Don't give estimates based on what you hope will happen. Nail down as much as you can. Flying by the seat of your pants is exhausting for everyone involved.
I've spent years employing this model and it has served me well. I give estimates, explain what they're based on, including any variables not under my direct control. I ANTICIPATE PROBLEMS. Then should a problem arise it doesn't seem like I'm making last minute excuses. I like nothing better than to get a job, do the job as expeditiously as I can and move on to the next one with predominantly happy customers in its wake.
I've seen what not doing it this way can do to a relationship. No thanks.
People always ask why in the world anyone would order a Carl Thompson that takes 3+ years to receive.
When I ordered my bass, he told me it would take 'about a million years' and I believed him... no exact timeframe, but the precedent set is that they take 3-5 years to get. Mine took under 3 years and I was ecstatic. 3 years is a crazy long time to wait for something, but it's what I signed up for, so there was no issue whatsoever.
Another builder told me I'd have my bass in 30 weeks, and it's now been a year an a half- THAT is frustrating. It'll be done in 2 weeks, done in 2 weeks, done in 2 weeks for 9 months now.
I've had the same issues come up with other small operations too, but unfortunately the way I see it is- musicians are quirky. We're artists. Unfortunately, the best artists happen to be the ones who build the most amazing products, have the poorest customer service, worst business plans, make the least money, and put the most heart into what they do. I've found that the more positive, reassuring, thankful, and understanding I am in these situations, the quicker and more thoroughly finished my products come. Plainly, if you want something off the shelf- it's out there, but if you want something special, you really have no choice but to put up with all the other baggage that comes along with it.
To quote Carl 'Wanna know how to get somewhere fast? Go slow.'
