LockMargin vs Bonsai: Honest Comparison for Freelancers
Bonsai costs $300–$948/year. LockMargin costs $49 once. Same invoicing, proposals, and contracts — with no transaction fees.
Bonsai is a popular all-in-one freelancer platform offering invoicing, proposals, contracts, and time tracking. It's well-designed — but the costs add up fast. At $25–$39/month plus 2.9% + $0.30 per credit card transaction, a freelancer billing $50K/year pays nearly $1,800 annually in combined subscription and fees.
LockMargin offers the same core features as a $49 one-time purchase, works 100% offline with AES-256-GCM encryption, and charges zero transaction fees. This comparison breaks down exactly where each tool wins and which one fits your freelance business.

Hidden Costs Breakdown
Here's what Bonsai doesn't advertise on their pricing page:
- Transaction fees: 2.9% + $0.30 per credit card payment. On a $5,000 invoice, that's $145.30 in fees.
- Plan limits: The Starter plan caps you at 3 active projects and 5 templates.
- Data lock-in: Your invoices, contracts, and client data live on Bonsai's servers. Export options exist, but you're dependent on their platform.
- Upgrade pressure: As your business grows, Bonsai pushes you to higher-tier plans with higher monthly costs.
LockMargin has no transaction fees, no plan limits, and no upgrade pressure. You buy it once and it's yours.
