Both tools are built for freelancers. Both do project management, CRM, and time tracking. But they make completely different bets about what freelancers actually need — and which side you fall on matters.
I want to be upfront about something before this comparison goes any further: I built Flowboard, so I have an obvious stake in how this reads. I've tried to write this as honestly as I can — pointing out where Bonsai is genuinely better, not glossing over the places where Flowboard doesn't match it. If you want a tool that handles contracts and invoicing end-to-end, Bonsai might genuinely be the right answer for you. I'd rather tell you that than have you buy the wrong product.
With that said, here's the real comparison — from someone who has used both, spent 25 years managing web projects professionally, and built Flowboard specifically because of the gaps I kept running into.
Bonsai is a freelance business management platform that covers the full client lifecycle — from proposal to contract to invoice to payment. Its real strength is the pipeline it creates between those stages. You write a proposal, the client signs it, it becomes a contract, tracked hours flow into an invoice automatically. For freelancers who bill by the hour and run a lot of client engagements end-to-end, that flow is genuinely useful.
Pricing runs from $15/month on the Basic plan (which is quite limited — no invoicing, no proposals, no contracts) up to $25/month on Essentials, which is where most freelancers actually land. Annually that's $300 a year for the features most freelancers need. Over three years: $900, and counting.
Bonsai is cloud-only. Everything is on their servers. There's no offline mode — which matters more than it sounds when you're doing client calls in a coffee shop with unreliable WiFi, or working while travelling.
Flowboard is an offline-first project management and sales CRM tool. It does kanban project boards, a full sales pipeline, time tracking, client quotes, AI-powered insights, and revenue forecasts. It costs between £39 and £59 as a one-time payment with no subscription. It installs as a desktop app, works fully offline, and stores your data locally.
What Flowboard doesn't do: invoicing, contracts, or payments. It's not trying to replace your accounting software. It's trying to replace the combination of Trello/Asana (for project management) and a basic CRM (for sales tracking) — not your FreshBooks or your HelloSign.
That distinction is important, and it's the main thing that determines which tool is right for you.
Both tools cover project management, time tracking, a sales CRM pipeline, and client quotes/proposals. If you're comparing them on those four features alone, here's how they stack up honestly:
The pattern is clear. Bonsai wins on invoicing, contracts, and payments — the financial and legal side of freelancing. Flowboard wins on project management depth, CRM pipeline, and AI. Both do time tracking well. Neither product does everything.
This is the part of the comparison that I think matters most, and it's the reason Flowboard exists.
To get Bonsai's CRM pipeline feature, you need the Premium plan at $39/month ($29/month annual). That's $348 a year. Over three years, $1,044 — and you're still paying. Forever. The meter never stops.
Flowboard's Full plan is £59 once. That's it. Updates included. No anniversary charges. The cost of Bonsai Essential for one year ($300) is five times what Flowboard Full costs for a lifetime.
I'm not saying subscription software is always wrong — there are good arguments for it when the product requires ongoing server costs, support, and active development. But when the subscription model is applied to software that a solo freelancer uses locally on their own computer, you're essentially renting something you could own.
Bonsai is cloud-only. This means your project data, client information, deal history, and time logs all live on Bonsai's servers. If Bonsai goes down (it happens), you're locked out. If your internet is unreliable, you're locked out. If you're working on a plane, a train, or a client site with terrible WiFi, you're locked out.
There's also a privacy dimension that I don't think freelancers talk about enough. Your client list, deal values, win rates, revenue — that's sensitive business intelligence. It sits on a third-party server, subject to their privacy policies, their data practices, and their potential future decisions about what to do with it.
Flowboard stores everything locally in your browser's IndexedDB. The data literally never leaves your device unless you explicitly enable cloud backup. Even then, it's encrypted and you can export everything at any time.
For some freelancers this won't matter. For others — particularly those handling client information subject to NDAs, or those who've ever lost access to cloud software during a critical deadline — it matters a lot.
I said I'd be honest, so here it is.
If invoicing and contracts are the core of how you run your business, Bonsai is better for you. The proposal → contract → invoice flow in Bonsai is genuinely well-designed. The legal templates save real money compared to having a solicitor draft your own. The automated payment reminders are useful. The tax estimation feature (for US freelancers especially) is something Flowboard simply doesn't have.
If you regularly send five or more proposals a month and want each one to convert automatically into a signed contract and then an invoice without manual steps, Bonsai has that built in a way that Flowboard doesn't replicate. Flowboard creates quotes and proposals — but it stops there. Getting from quote to signed contract to invoice is outside its scope by design.
Bonsai is also more suitable for small teams with two or three people. Flowboard is built for one person running their own business. If you're collaborating with even a part-time assistant or a business partner, Bonsai's multi-user features are more developed.
Project management depth. Bonsai's project management — even the reviews from its own fans admit this — is "basic." Tasks and deadlines. Flowboard has a full kanban board with customisable stages, progress bars, priority tags, stale warnings, resource links, project health tracking, and AI-generated retrospectives when a project closes. If you're managing complex client projects with multiple stages and deliverables, Bonsai's project view will frustrate you.
The sales CRM. Bonsai's deals pipeline only appears on the Premium plan ($39/month). Even then, it's simpler than Flowboard's. Flowboard has win probability auto-calculation, follow-up reminders with email notifications, lead source tracking, revenue forecasts with AI commentary, and a dashboard that shows you your pipeline health at a glance. For freelancers where business development is a meaningful part of their week — chasing leads, sending proposals, following up — Flowboard's CRM is meaningfully better.
AI insights. Bonsai has none. Flowboard uses Claude AI to analyse your actual projects and deals and surface what needs attention. It's not a chatbot bolted on — it reads your pipeline, your projects, your stale deals, and tells you specifically what to do. After 25 years of managing digital projects, I can tell you that this kind of pattern recognition is the thing I always wanted a tool to do. Bonsai doesn't come close.
Privacy and offline. Already covered — but worth repeating. If data ownership matters to you, Flowboard wins outright.
Actually a reasonable option for some freelancers. Bonsai's Basic plan at $15/month covers invoicing, contracts, and time tracking. Flowboard handles project management, CRM, and AI insights. Together you'd be paying roughly $180/year plus a one-off £59 for a combination that covers almost everything.
That said, most freelancers I've spoken to find that they primarily need one or the other. If your business is built around winning clients and delivering complex projects, Flowboard covers the things you care about most. If it's built around getting contracts signed and invoices paid, Bonsai's pipeline is more relevant.
Bonsai is a well-made product with a loyal user base for good reason. If contracts, invoicing, and payment processing are central to how you run your freelance business, it's worth the subscription. The proposal-to-payment pipeline it creates is genuinely well-designed, and nothing in Flowboard replaces that.
Flowboard is the better choice if you want to own your tools outright, you need serious project management beyond basic task lists, you actively manage a sales pipeline, and you want AI that analyses your actual business rather than just formatting templates. The price difference over time isn't close — and for freelancers who already use dedicated invoicing software like FreshBooks or even just send invoices via their accountant, paying a subscription for Bonsai's invoicing feature on top is genuinely wasteful.
The question I'd ask yourself is simple: what's costing you the most time right now? If it's chasing invoices and getting contracts signed — look at Bonsai. If it's losing track of leads, managing complex projects, and having no visibility into your business performance — look at Flowboard.
Project management, sales CRM, time tracking, client quotes, and AI insights — in one offline desktop app. From £39 one-time, no subscription.
