FastBill alternative
Billy vs. FastBill: what does the AI actually do for you?
FastBill is a solid German invoicing tool with receipt recognition (OCR) and VAT return preparation. Billy goes one step further: instead of just reading receipts, Billy's AI assistant creates your invoices, quotes and reminders itself — on request, in seconds.
Both start at €9 a month. The difference is whether the "automation" speeds up your typing (FastBill) or takes the work off your plate entirely (Billy).
Why freelancers switch from FastBill to Billy
FastBill's strengths are receipts and VAT prep. If your bottleneck is writing and chasing invoices, Billy solves exactly that.
- Invoice from a prompt: describe it instead of filling it in
- The AI assistant sends payment reminders and formal Mahnungen automatically
- Professionally designed templates with live preview
- Germany and Austria in one account
- Recurring invoices set up in one sentence — created and sent on schedule

When FastBill is the better choice
To be fair: if you want to collect receipts and prepare your VAT return in the same tool, FastBill covers that — Billy deliberately does not, focusing on invoices, quotes and dunning instead.
