Vendor Consolidation & Procurement Support


In addition to our installation services, Cetus Solution also helps construction and property professionals simplify purchasing and reduce costs through strategic vendor consolidation.

We negotiate competitive pricing and provide superior customer service across key building categories including windows, doors, kitchens, roofing, siding, lumber, hardware, flooring, and more. By reducing the number of suppliers you manage, we help organizations increase buying power, streamline vendor relationships, and unlock meaningful savings through volume-based pricing and rebate opportunities.

With a structured, efficient approach and a focus on long-term partnerships, Cetus Solution makes procurement easier, more cost-effective, and more reliable for every project.
