SQUARE INVOICES ALTERNATIVE
LockMargin vs Square Invoices — Fee Trap | $49 Once
FreshBooks is beautiful, cloud-based invoicing — but at $19-60/month, you're renting software you could own. LockMargin is invoicing-first with time tracking, expenses, and recurring billing — all for $49 once, Local-first by default.
The Rental Reality — "Square Invoices 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 Square Invoices, the answers are theirs. With LockMargin, they are yours.
Migration path
"Moving off Square Invoices 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."
