About Flow

Flow is an invoicing service built for UK freelancers and small businesses. You pick a professional template, add a logo and brand colors, enter your own and your client's details and send the invoice with one click, and Flow follows up with automatic reminders. Stripe payment links let customers pay in their preferred way, and a payment tracker shows when money is coming in.

Further features include time-based invoicing, bills by date range or project and recurring schedules, automatic late payment fees, CIS invoicing for construction subcontractors under the Construction Industry Scheme and EU compliance features. The site lists HMRC, GDPR and ICO registration claims, a demo invoice, guides, weekly product updates and comparison pages. A companion app, Unaccountable, covers tax returns, expenses and income for self-employed people. The site says you can start free without a credit card and upgrade later, and it also promotes a lifetime VIP option with a one-time payment and no monthly or yearly fees.
