SubPay is browser-based construction payment software for UK subcontractors, specialist contractors and small commercial teams. It connects contract payment rules, applications, Payment Notices, Pay Less Notices, deadlines, service evidence, deductions and receipts in one commercial record. Teams can reconcile payments and shortfalls, monitor retention and CIS deductions, review aged debt and cash flow, and export PDF or CSV records. A permanent free plan supports up to three active contracts without a card or trial clock.
