This.

Ever notice when there’s a new building going up, and the building looks complete, after just a few months, but it doesn’t open its doors for another year?

That’s because all the “finish work,” like carpeting, drywall, painting/wallpaper, doors, etc., takes forever.

It also generally requires the most expensive employees.

That’s one reason a Mercedes costs three times as much as a Toyota. They seem to be fairly equivalent, but the Merc has a whole lot more “finish,” and that costs a lot.

Most folks find they can live without that extra polish, when they learn the cost. Toyotas are excellent vehicles, and have a reasonable cost.

So, a big part of commercial feasibility, is learning where the “sweet spot” lies, so the last 10% takes only 40% of the time, and the customer is happy.

For myself, I like to do “the full Monty,” and go for 90%, but it has been my experience that no one wants to pay for it.

So I do it for free.
