My builder uses Houzz Pro to plan the timeline and give detailed estimates and daily updates with photos of progress, and provide invoices at pre-agreed key points in the build. This made the whole experience much more efficient and stress-free.
An easy way to tell if the flooring was custom finished is to look closely to see if there are bevels between the planks. No bevels usually means custom on site finish. :-)
