What you need
- Get paid without the awkwardness
- Write an invoice in under a minute, send it the way your client actually talks to you, and see at a glance what’s paid and what’s overdue.
- Know what you’re owed and what to set aside
- Thistle Invoice shows what’s outstanding, and its tax jar estimates what to put aside. It’s an estimate, not tax advice.
- Keep a proper mileage record
- Thistle Miles is built to log work drives by itself and value them at your country’s official rate, so you aren’t reconstructing the year from memory.
- Keep your records yours
- There’s no account and no cloud. What you write stays on your iPhone.

- Is Thistle Invoice tax advice?
- No. It helps you create invoices and keep records. You’re responsible for what your invoices say and the tax you pay, and the tax jar is an estimate.
