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 Lexware Office 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.
