How do building-materials distributors automate the quoting process?

They swap manual, line-by-line data entry for software that reads the request, identifies each product, and matches it to the right SKU and price on its own — so the estimator reviews and approves instead of typing. A request comes in, the system extracts the items, matches them against your catalog (suggesting substitutes when something's out of stock), applies the right customer pricing, and produces a quote you can print, export, or push into your ERP. That's exactly what Quantity Supply does, with a person confirming the final quote.
