From layout to quote: why the bill of materials should come from the drawing

Every store project follows the same path: someone draws the layout, someone turns the drawing into a bill of materials, and someone turns that list into a quote. None of these steps is the problem. The handoffs between them are.

Where errors get in

In most companies, each step uses a different tool. The layout lives in CAD, the bill of materials in a spreadsheet, and the quote in the ERP or yet another spreadsheet. As long as the project doesn't change, this works. But the project always changes.

The customer asks for one more gondola module. A wall dimension was wrong. The finish moved from white to graphite. Each change has to be repeated in three places, by different people, usually on a tight deadline. That's where the missing bolt, the end cap left out of the quote and the proposal sent with the previous revision come from.

One source

The alternative is to treat the drawing as the source of the information. Every part placed in the layout already knows what it is made of: components, quantities, codes and finishes. When a dimension changes, the list changes with it, and the quote is calculated from that list.

In practice, that means:

• Fast revisions. Changing a gondola's length recalculates its items without reopening spreadsheets.
• Less manual checking. The team checks rules and prices once, in the product setup, not in every project.
• The right information for each team. Sales gets the proposal, purchasing gets the list and production gets the manufacturing details, all from the same revision.

Where to start

Start with the product that generates the most revisions. Set up its rules — allowed combinations, dimension limits, finishes — and use that setup on the next projects. The payoff shows the first time a customer asks for a last-minute change and the quote goes out right on the same day.

That is exactly the path WBCcad was built to shorten.
