Freelancers stitch together five or more separate tools - one for invoices, one for contracts, one for proposals, one for project tracking, one for client communication - and still get stiffed on payments. The tools take a cut. The clients take their time. The freelancer takes the hit.

PayShield replaces that stack with one workspace and zero platform fees, and it is the only freelance OS built around the late-payment problem from day one - with free public tools for demand letters and statutory late-fee calculation under EU Directive 2011/7 and the UK Late Payment of Commercial Debts Act 1998.

The project is run by Damian Diaz, an independent engineer who got tired of watching friends and collaborators eat unpaid invoices. PayShield is built to be the tool he wished existed.
