Build a Client Portal with FlowFn

Agencies, consultancies, and B2B teams all hit the same wall: clients want a single place to check their projects, invoices, and files — and emailing PDFs back and forth doesn't scale. A client portal fixes it, but building multi-tenant auth (each client sees only their own data) usually means real engineering. In FlowFn it doesn't: end-user sign-in, per-client data scoping, and a polished portal page are features you assemble, not code you write.
