Flow

Flow is an invoicing platform designed for freelancers, contractors, and small teams, focusing on time-based billing, project tracking, and automated payment reminders. It supports specific regulatory requirements for UK users, including CIS subcontractor invoicing, VAT handling, and HMRC compliance. The platform integrates with Stripe for direct payments and offers features like recurring invoices, late payment fees, and detailed cash flow reports. It also includes a companion app called Unaccountable for managing tax returns and expenditure.

Built specifically for UK freelancers with native CIS, HMRC, and GDPR compliance, reducing the need for separate accounting software for basic invoicing and tax preparation.
