Siteline is billing and accounts receivable software built specifically for commercial subcontractors (trade contractors). It centralizes pay applications (including AIA G702/G703 progress billing), lien waivers, lien rights, compliance documents, change orders, collections, and A/R reporting in one workflow, replacing the spreadsheets, PDFs, and GC payment-portal logins that AP/AR teams juggle every month. Siteline integrates with construction accounting systems (Sage, Foundation, Viewpoint/Vista, Spectrum, QuickBooks, Acumatica, Sage Intacct, NetSuite, CMiC, and others) and with GC payment portals (Textura, GCPay, Procore Pay) so billing data flows without double entry. Founded in 2019 by Claire Wilson and Gloria Lin, backed by Menlo Ventures and First Round Capital; subcontractors have billed over $10B across 200,000+ projects on the platform. Siteline publishes no public developer API — integrations are managed connections rather than a self-serve API.
