Long ago I used to fight that Battle. Now I profit from it.
What you have to do is make the Distinction of Install Versus Product Placement.
I work closely with a local appliance store that I send 90% of my customers to.
All these Hi-End appliances are price Colluded. There are No significant discounts ....
They are very good at working with the builders & my self and they understand the importance of the service.
I do not receive any compensation other than that we refer each other. ( My own house was cost)
If they left the 48"Sub -Zero or Wolf range in the Garage, they know they will be back to put it in front of the Cabinet opening !
I do no Plumbing or Electric hook-ups.
Placement is getting the correct specs.
It has been the rare occasion that we have not been able to figure Specs out.
Most Important-Model # from the Appliance Dealer Invoice only !!
If it changes after plan Sign-offs,Change order fee $$ !
The Builder & or Homeowner are C/C in on all of this.
A Dropbox file is created as we gather the specs,also to making sure other trades have the specs for Plumbing & Electric.
Placement is drilling for supply lines and
leveling,securing the Appliance in it's opening.
A Chimney Hood Placement states that the ductwork shall be in the room for our connection. We do no exterior work- No siding or roofing.
A Dishwasher placement,$$.
A DW with Panels is,$$$...
A Fisher Paykel is $$$
A U-line ref is $$$ and it states that they Never line up flush with surrounding cabinetry!.
A 48" Range is $$$....
All these are separate invoice Line Items in QB that are part of our contract. Got about 2 dozen SKU's in QB under Appliance Placement. Makes for quick pricing.
These charges are explained that Pro appliances require Pro Placement and are separate from the cabinet install charges.
The attached pic of a commercial job,the appliance placement cost more the the cabinet install !
