Flow

Flow is a modern invoicing platform built for freelancers, contractors, and small teams who bill by time, dates, or projects. It turns your real work into clear, professional invoices with support for time-based billing, date-range calculations, recurring schedules, CIS for UK construction, and VAT done right. With Flow, you move smoothly from work done → invoice sent → cash collected, all in a simple, fast interface that fits naturally into your daily workflow.
