Frequently asked questions
Is the invoice generator really free?
Yes, completely free and no sign-up. Fill in the form, preview the invoice and download it as a PDF. No credit card, no email required.
Are my invoices legally compliant?
The generator includes the mandatory details of a professional invoice (sequential number, dates, seller and client identity, line items, VAT, net and gross totals). Add your company registration number, and a VAT-exemption notice appears automatically when VAT is set to 0%.
How do I download my invoice as a PDF?
Click "Download as PDF": your browser's print dialog opens, choose "Save as PDF" as the destination. The invoice prints cleanly on its own, without the rest of the page.
Is my data stored anywhere?
No. Everything runs in your browser: nothing is sent to a server. Your details are only kept locally on your device so you don't have to retype them next time.
What if I need to invoice every week?
Filling in a form every time quickly gets repetitive. With Robi, you say "€500 invoice for Alice" and AI generates the compliant document in 30 seconds, sends it, chases late payers and collects via Stripe. The generator is great for one-off needs; Robi is for invoicing every day.
