What is FreeAgent?
FreeAgent is UK-based cloud accounting software built for small businesses, freelancers, contractors and landlords. It brings invoicing, expenses, tax and reporting into one place and files directly to HMRC, taking the fear out of self-assessment and VAT for people who run their own business but aren't accountants.
What is FreeAgent?
FreeAgent handles the full money side of a small business: raising invoices and chasing payment, capturing expenses, tracking projects and time, connecting to your bank, and turning all of it into the tax returns HMRC expects. Because it's designed around UK tax rules, it can file Self-Assessment and VAT returns directly and is a recognised solution for Making Tax Digital (MTD).
Who it's for
FreeAgent is aimed at UK sole traders and freelancers, limited companies, contractors, and landlords, as well as the accountants and bookkeepers who support them. It's ideal for anyone who wants to stay on top of their books and file taxes correctly without hiring out every part of the process.
Key features
- Invoicing with automated reminders and online payment options
- Expense capture with AI-powered Smart Capture
- Self-Assessment and VAT returns filed directly to HMRC
- Making Tax Digital (MTD) for Income Tax compliance
- Integrated payroll with Real Time Information (RTI) submission
- 90-day cashflow forecasting
- Bank feeds via Open Banking
- Full mobile app access
Tax without the panic
FreeAgent's biggest draw is how it demystifies UK tax. As you invoice and record expenses through the year, it continuously works out what you'll owe, then lets you file Self-Assessment and VAT straight to HMRC when the time comes — no spreadsheets, no last-minute scramble, and full MTD compliance built in. For sole traders and small limited companies, that alone can replace a lot of accountant hours.
Everyday bookkeeping made simple
Open Banking bank feeds pull transactions in automatically, Smart Capture reads receipts so expenses log themselves, and 90-day cashflow forecasting shows what's coming so there are no nasty surprises. Invoices can be sent with automatic reminders and online payment links, helping small businesses get paid faster with less chasing.
Integrations and support
FreeAgent connects with tools like Dext and Amazon and other business services, and is backed by a UK-based human support team — a meaningful reassurance when the questions are about your own tax. It carries strong customer ratings and industry recognition for its ease of use.
Pricing
FreeAgent offers a genuinely free tier for customers who bank with NatWest, RBS, Ulster Bank or Mettle, and otherwise monthly plans roughly £5–£33 depending on whether you're a landlord, sole trader or limited company, often with introductory discounts. A 30-day free trial with no card required lets you try it first.
Payroll and projects
Beyond the books and tax, FreeAgent covers running a small operation day to day. Integrated payroll with RTI submission handles paying yourself or a small team and reports it to HMRC correctly, while project and time tracking let contractors and agencies see profitability per job and bill accurately. For a one-person company, having payroll, projects, invoicing and tax in a single tool removes a surprising amount of scattered admin.
Why choose FreeAgent
For a UK freelancer, contractor or small limited company, FreeAgent is one of the most reassuring ways to run the books and stay on the right side of HMRC. The combination of everyday bookkeeping, direct MTD-compliant filing, real UK support and (for some banks) a free plan makes it a standout choice for people who'd rather spend time on their business than on tax admin.
What is Invoice Ninja?
Invoice Ninja is free, open-source invoicing and billing software built for freelancers, consultants and small businesses that need to look professional and get paid faster. Trusted by more than 200,000 businesses and running since 2014, it bundles invoicing, online payments, quotes, time tracking and expense management into one platform you can use in the cloud or self-host on your own server.
What is Invoice Ninja?
Invoice Ninja lets you create polished, branded invoices in minutes and send them to clients who can pay directly from the invoice in a single click. Around that core it adds the surrounding workflow most small businesses juggle across several tools: quotes and proposals, recurring and auto-billing, a branded client portal, expense and vendor tracking, and project management with Kanban boards.
Who it's for
The platform is a natural fit for freelancers, contractors, designers, developers, consultants and accountants — anyone who bills clients and wants a dependable, low-cost way to manage the money side of the business. The generous free plan makes it especially attractive for solo operators and new businesses watching every expense.
Key features
- Professional invoicing with customizable templates
- One-click online payments from the invoice
- Recurring and automatic billing
- Quotes, proposals and e-signatures
- Time tracking and Kanban-style project management
- Expense and vendor management
- A branded client portal
- Bank and credit-card transaction import
- Multi-factor authentication and PCI-DSS compliance
Payments and integrations
Invoice Ninja accepts payments through a wide range of gateways including Stripe, PayPal, Square and GoCardless, so clients can pay however they prefer. It connects with more than 50 services — QuickBooks, Gmail, Slack, Mailchimp and hundreds more — via Zapier, Make and Pabbly, and its API and self-hosting options make it a favorite among technically minded users who want full control of their data.
Open source and self-hosting
Unlike most billing tools, Invoice Ninja is open source with a public GitHub repository, and it can be self-hosted for teams that want to own their infrastructure and data outright. That transparency is a large part of why developers and privacy-conscious businesses gravitate to it.
Pricing
The Free plan is genuinely free forever and covers the essentials for a small client list, with no credit card required. Paid tiers add more templates, clients and advanced features: Ninja Pro at around $14/month, Enterprise at around $18/month, and a Premium Business tier for larger operations. A 30-day money-back guarantee backs the paid plans.
Getting paid faster
The whole product is oriented around shortening the gap between sending an invoice and receiving the money. Auto-billing charges recurring clients on schedule, payment reminders chase overdue invoices for you, and the one-click pay experience removes the friction that makes clients delay. Because customers can pay by card, PayPal or direct debit straight from the invoice, there are fewer excuses and fewer late payments.
Security and reliability
Invoice Ninja takes the money side seriously, with multi-factor authentication to protect accounts and PCI-DSS compliance for card handling. Self-hosting adds another layer of assurance for businesses that would rather keep financial data entirely on their own infrastructure, and the open-source codebase means the security model is transparent and auditable rather than a black box.
Why choose Invoice Ninja
Invoice Ninja's pitch is simple: professional invoicing and full billing workflow without the subscription bloat. The combination of a real free tier, open-source transparency, self-hosting and one-click payments makes it one of the best-value ways for independent businesses to bill clients and get paid on time. For freelancers and small teams who resent paying a premium just to send an invoice, it is one of the strongest options on the market.
