About Siteline

Siteline builds billing and payment infrastructure for construction contractors and project-based businesses. The core problem: construction billing relies on manual invoicing and fragmented payment collection, leaving contractors waiting weeks to receive cash they've already earned. Siteline automates the entire billing-to-payment cycle, connecting job data, labor, materials, and subcontractor costs into accurate invoices that route to customers, then tracks payment status in real time. The company operates in the United States and Mexico, with a lean team split between engineering, sales, and support. Founded in 2019 and based in San Francisco, Siteline targets contractors at all scales—from single-operator crews to mid-market firms managing multiple concurrent projects.
