Invoice24/i24 is an online accounting and invoicing tool from i24 Limited for UK small businesses, sole traders, limited companies, and freelancers. Its positioning is clear: send invoices, manage expenses, prepare for VAT/MTD, and help users get ready for Making Tax Digital for Income Tax, which is being rolled out from April 6, 2026.
The disclosed features mainly target day-to-day operations for micro and small businesses. They include unlimited invoices and estimates, unlimited business creation, receipt photo capture, expense categorization, mileage tracking, cash-flow insights, Self Assessment preparation, CIS calculations and filing, deadline reminders, and automated payment follow-ups. For payments, users can add payment links to invoices and accept debit and credit card payments via Stripe; the site also mentions card and Klarna payable invoices. Multi-currency support covers 145+ currencies, but the terms also note that Invoice24 is not fully optimized for multi-currency collections. If you receive both USD and GBP, it recommends managing them through separate accounts. HMRC/MTD integration is included in the terms, but several places indicate that MTD submission or MTD for Income Tax features are still βcoming soon.β
In the pricing information, the Core plan is marked as Promo Free and includes unlimited invoices, expense management, CIS, cash-flow insights, customer support, and one free 45-minute onboarding session. The page also states that all prices are subject to 20% VAT, while the terms mention possible monthly, quarterly, and annual auto-renewing subscriptions, though full paid tiers are not disclosed. Support is a highlight: it offers real human product support, live chat, screen sharing, and phone support, along with video tutorials and jargon-free guides.
The strengths are its low barrier to entry, free unlimited invoicing, and design around UK tax scenarios, making it suitable for self-employed users and micro companies that want to quickly standardize invoicing and expense records. The downsides are that its core MTD capabilities are not fully live yet, and information is missing on team collaboration, role permissions, approvals, APIs, and enterprise-grade security certifications. Support for more complex charts of accounts, inventory, group finance, or localized tax requirements is also unclear.
It is better suited to freelancers, contractors, sole traders, and small limited companies operating in the UK, especially users who need invoicing, expense records, CIS, and future MTD preparation. The source text does not provide information on access from mainland China, so this remains unknown. Payments depend on Stripe, Apple/Google platforms, or bank card systems, so use by China-based entities may be limited by account availability, currency, and compliance requirements. If your main market is China, it is generally better to evaluate local finance, tax, and invoicing alternatives such as η¨ε, ιθΆ, η₯¨ι, and ηΎζδΊ.
