Lyn sifus,

What I was mentioned to me recently:-
1. Site visit where we also let them know the main requirements/budget
2. ID comes out with rough quotation (ballpark figures) asks whether we are interested or not. ID offered to sketch on paper the rough design.
3. Make payment of 20%
4. They proceed with detailed 3D design (with one free redraw) and detailed quotation containing materials and exact figures
5. Make payment of 35% for materials
6. After certain progress performed on site, then subsequent payments of 35% will be made (split over 17.5%)
7. Then after site inspection - then make final 10%

Things excluded: no change to structure or architecture / no extention so no need permit from local council.

Normally what is the process like for dealing with interior designer. Is the above normal? And if you have any tips / tricks to dealing with them, it will be helpful too.
TQ
