Invoice like a developer – with Meister Bill

As a developer, you hate bloated software, unnecessary clicks, and tools that waste your time. That's exactly why we built Meister Bill: a clean, focused invoicing tool that feels more like your IDE than traditional accounting software. Create legally compliant invoices in seconds – without the bureaucracy overhead.

Built for developers

Meister Bill strips away the bloat and gives you exactly what you need:

Clean, minimal interface – no clutter, no distractions
API-first design – integrate with your existing workflow (CRM, project management, time tracking)
Automated tax calculations for EU, US, and international clients
Multi-currency support – bill clients worldwide
Version control friendly – export your invoices as JSON or Markdown
Optional voice commands – because sometimes typing is overrated

Real-world examples

Whether you're a freelance developer, running a micro-SaaS, or building client projects – Meister Bill adapts to your workflow:

Freelance Project

"Invoice client Acme Corp for React dashboard development, 40 hours @ €120/hour, due in 14 days."

→ Automatically calculates €4,800, applies correct VAT based on client location, generates invoice number, sends PDF.

SaaS Subscription

Set up recurring invoices for your SaaS customers via API. When a customer upgrades from Starter ($29) to Pro ($99), automatically generate a prorated invoice.

→ Integrates with Stripe, Paddle, or your custom billing system.

Open Source Consulting

Track multiple small consulting gigs across different countries. Bill a US startup in USD, a German agency in EUR, and a UK client in GBP – all with correct tax handling.

→ Automatic currency conversion, tax compliance, and DATEV export for your accountant.

API-first for automation nerds

Why manually create invoices when you can automate them? Meister Bill offers a RESTful API that lets you:

Create invoices programmatically from your project management tools
Auto-generate monthly retainer invoices via cron jobs
Sync with your time tracking (Toggl, Harvest, Clockify) and bill automatically
Integrate invoice data into your custom dashboards or reporting tools

curl -X POST https://api.meister-bill.com/invoices \

  -H "Authorization: Bearer YOUR_API_KEY" \

  -d '{

    "customer_id": "uuid-123",

    "items": [{"description": "API Integration", "hours": 20, "rate": 150}]

}'
