About FastBill

FastBill has carved out a solid niche as an invoicing-first platform that bridges the gap between simple invoice generators and full accounting software. For service-based businesses—particularly agencies, consultants, and freelancers who bill by project or hourly rate—FastBill offers a streamlined workflow that prioritizes getting invoices out quickly and tracking payments efficiently. The platform includes time tracking capabilities, allowing you to log hours against projects and then convert those hours directly into invoices. This makes it particularly valuable for businesses that bill based on time spent rather than fixed project fees. While FastBill includes basic accounting features like expense tracking and banking sync, it's not as comprehensive as lexoffice or sevDesk for full bookkeeping. However, for businesses where invoicing is the primary concern and accounting can be handed off to a Steuerberater, FastBill provides a focused, efficient toolset without the complexity of full accounting software.

Flexible Pricing Plans

  • €9/month for Starter with basic invoicing
  • €24/month for Professional with time tracking
  • €54/month for Plus with team collaboration
  • No per-transaction fees, unlimited invoices

Streamlined Invoicing Workflow

For service businesses, FastBill prioritizes speed and efficiency. Create an invoice in under a minute from templates or past invoices, send to clients via email, track when it's opened and paid, and automatically send reminders for overdue payments. The time-to-invoice metric is critical for cash flow—FastBill excels here, helping you send invoices within hours of completing work.

Time Tracking and Project Invoicing

  • Track billable hours per project in app or browser extension
  • Convert logged hours directly to invoice line items
  • Hourly rate configuration per project or client
  • Generate timesheets for client documentation
  • Auto-calculate invoice totals from hours logged

Banking and Expense Features

  • Bank account sync for payment reconciliation
  • Automatic payment matching to invoices
  • Expense tracking for project profitability analysis
  • Multi-currency support (EUR, USD, GBP, etc.)
  • Stripe and PayPal integration for online payments

Market Positioning

FastBill vs. lexoffice vs. sevDesk: lexoffice is more comprehensive for accounting and tax compliance. sevDesk includes more CRM features. FastBill wins on simplicity and speed for invoicing-centric workflows. For agencies and consultants who hand off accounting to a Steuerberater, FastBill is the perfect lean tool. For businesses needing integrated accounting, lexoffice is better.
