The agency standard for simple billing.
Bill for campaigns and services with ease. Agency-grade invoices without the bloat.
"I built this because Excel was too fragile."
As a designer with ADHD, billing was always a chore. I’d spend 15min staring at Excel making sure I didn't accidentally corrupt my payment details.
I built invoicein30 for the solo founder or freelancer who just wants to get paid. I needed a tool that looked professional, met standards, and was impossible to "break."
I even consulted with a professional accountant to ensure the templates handle the core fields most European companies require.

Frequently Asked Questions
Is this for Marketing Agencies?
If you are a solo founder, freelancer, or micro-agency who hates wrestling with Excel and wants to look professional without the "enterprise" complexity, yes. If you are a corporation with 50 employees and complex inventory needs, this might be too simple for you.
How safe is my data?
100%. We are a software utility, not a data broker. Your client lists and presets are encrypted and stored in a secure database solely for your convenience. We never sell, share, or analyze your business data.
How is this better than Excel?
Excel is a calculator; invoicein30 is a workflow. We handle the currency formatting, the layout, the VAT logic, and the translations automatically. It is much harder here to accidentally "break" a cell and ruin your tax report.
How do I know if my invoice is compliant?
I consulted with a professional accountant to ensure invoicein30 supports the standard requirements for Latvian and EU billing (including Reverse Charge and mandatory footer clauses). However, the tool is flexible. You can easily add custom fields if your specific industry requires extra "fine print."
Honest Data Storage
We don't believe in "Free" apps that sell your data. We store your business details and settings in a secure database so you can access them anywhere and on the go. We use Supabase (PostgreSQL) for industry-standard encryption. Your financial details are your business. We just provide the tool to get paid.
