Bonsai vs FreeAgent: Which Is Better in 2026?

Bonsai is an all-in-one business management platform built for freelancers, independent professionals and small agencies. It brings together the paperwork and money side of running a service business — proposals, contracts, invoicing, payments, time tracking, expenses and light accounting — into one connected system, so solo professionals can look polished and get paid without juggling a dozen tools.

Proposals and contracts

Bonsai helps freelancers win and formalise work with professional proposals and legally-informed contract templates. You can send a branded proposal, turn it into a contract, and collect an e-signature, all in one flow. Templates tailored to different services (design, writing, consulting, photography and more) save time and help protect both sides of the agreement — a common pain point for independents who'd rather not draft contracts from scratch.

Invoicing and payments

Invoicing is a core strength. Bonsai lets you create branded invoices, set up recurring or milestone billing, request deposits, and send automatic payment reminders so you spend less time chasing late payers. Clients can pay online by card or bank transfer, which speeds up cash flow. The system ties invoices to your projects, contracts and tracked time so billing is accurate and consistent.

Time tracking, expenses and taxes

Bonsai includes time tracking and task management to keep projects on schedule, plus expense tracking and reporting that make tax season far less painful. For many freelancers it becomes the financial hub of the business — showing income, expenses and profitability in one place, and helping set aside what's needed for taxes.

Who it's for

Bonsai is designed for freelancers, consultants, creatives and small agencies who want to run the administrative side of their business smoothly and professionally from a single app, rather than stitching together separate contract, invoicing and accounting tools. It's especially valued by those who want their client-facing documents to look sharp and their back office to stay organised.

For independent professionals who'd rather spend time on client work than on admin, Bonsai offers a cohesive, well-designed way to manage proposals, contracts, invoices and finances end to end.

Why freelancers choose Bonsai

Bonsai's biggest appeal is consolidation: instead of paying for and switching between a proposal tool, a contract app, an invoicing service and a spreadsheet for expenses, freelancers get it all in one cohesive platform where everything is connected. A proposal becomes a contract, which links to a project, which generates invoices based on tracked time — with expenses and tax estimates flowing alongside. This joined-up workflow saves time, reduces errors and makes a solo operator look genuinely professional to clients. For freelancers and small agencies who want their admin handled so they can focus on the work they were actually hired to do, Bonsai is a thoughtfully designed, all-in-one home for the business.

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.
