BONSAI ALTERNATIVE
LockMargin vs Bonsai: Why I Switched After Paying $468 for One Year
Bonsai is beautiful — until you calculate the real cost. $468/year subscription + 2.9% transaction fees. LockMargin is $49 once. Zero fees. Local-first by default.

The Rental Reality — "Bonsai rents you access. You pay every month, your data lives on their servers, and the price can change whenever they decide. Stop paying — and you lose access to your own business history. That is the rental model."
The Ownership Alternative — "LockMargin is once. Your data lives on your machine, encrypted with AES-256-GCM, derived with Argon2id, stored in SQLite you can read with any tool. No account, no telemetry, no subscription. Export to JSON, CSV, PDF whenever you want — today or in ten years."
The Landlord Test
- Can you open your files without their software, their servers, or their permission?
- If you stopped paying tomorrow, how much of your business could you still run?
- Do you know exactly where your data is right now, physically?
- Can they change the terms — or the price — after you've built your business on it?
- If they shut down on Friday, what do you have on Monday?
With Bonsai, the answers are theirs. With LockMargin, they are yours.
Migration path
"Moving off Bonsai is honest work: export your clients and invoices (CSV or PDF), import what matters, run both for a month. Expect an afternoon of CSV cleanup, not a magic button."

The Hidden Costs Bonsai Does Not Advertise
I signed up for Bonsai thinking $39/month was reasonable. Then the real costs appeared:
Transaction Fees
Every time a client pays by card, Bonsai takes 2.9% + $0.30. On a $5,000 invoice, that's $175 in fees. LockMargin charges nothing — you keep 100%.
Upgrade Pressure
Bonsai's Starter plan ($25/mo) limits clients and projects. To unlock unlimited, you need Professional ($39/mo) or Business ($49/mo). Each tier adds features you might not need — but you pay for anyway.
Data Exfiltration Cost
If you stop paying, you lose access. Exporting all your data before cancellation is mandatory. With LockMargin, your SQLite database is on your machine. Pay once, access forever.

The Account Risk No One Talks About
Bonsai: Cloud Dependency
- Terms of Service violations can result in immediate suspension
- Data is hosted on Bonsai's servers — you cannot access it offline
- If Bonsai changes pricing or terms, you have no choice but to accept
- Export required before cancellation — if suspended, you may not get the chance
- Vlad S. from Kharkiv experienced this: "I work from trains, cafГ©s, and airports. Bonsai needed internet. LockMargin works everywhere."
LockMargin: Data Ownership
- No ToS can suspend your access — the file is on your machine
- Local-first by default — generate invoices on a train through rural Poland
- No pricing changes — you already paid $49, that's it forever
- No export needed — your data is already in a standard SQLite file you control
- Argon2id + AES-256-GCM means only you can read your data

Our TCO calculator uses the following methodology:
- Bonsai subscription: Monthly plan price Г— 36 months.

Does LockMargin have proposals and contracts like Bonsai?
LockMargin supports professional quotes and proposals via PDF export with custom branding. For contracts, you generate a PDF in LockMargin and send it through any free e-signature tool (DocuSign, SignRequest, or HelloSign). While not native e-signature, this keeps your contracts on your machine until you choose to share them.
What happens to my data if I stop paying Bonsai?
Your Bonsai account is suspended and you lose access to your invoices, contracts, and client data. You must export everything before cancelling. With LockMargin, you own your license forever. Your data lives in a single SQLite file on your computer. No subscription, no suspension, no surprises.
Is LockMargin really Local-first by default?
Yes. LockMargin is a desktop application that runs entirely on your computer. Your data is stored locally in an encrypted SQLite database. No cloud servers, no internet required for invoicing, no data leaves your machine unless you explicitly export a PDF or backup file.
Does LockMargin work for teams?
