ChronoFlow helps agencies manage retainers without spreadsheets. Track time entries per client, sell prepaid hour packages, and see exactly how many hours remain with clear status indicators. Invite your team, control access with roles, and generate shareable reports for clients. Built as a multi-tenant app, each organization's data stays isolated. Stripe handles subscriptions and payments so billing stays predictable as you grow. Set start/end dates, track usage history, and renew in time fast.
