Sinq

SINQ is a purpose-built, web-based platform designed to bring clarity, consistency, and collaboration to construction variation management. We provide a single, stand-alone solution that connects subcontractors, main contractors, and clients — allowing all project variations to be captured, reviewed, and agreed through one transparent portal. Whether you're on-site or in the office, SINQ ensures that every change is clearly documented, tracked in real-time, and fully visible to all parties. The result? Fewer disputes, faster approvals, and complete accountability from start to finish. SINQ — One Portal. No Disputes.
