The client receives a link in the form `https://yourdomain.com/factuur/[token]`. On that page they see:
- Your agency name, address and email (from agency settings)
- Client details
- Invoice number, invoice date and period
- Invoice lines with VAT breakdown
- Total amount
- A Print / Download button at the top
The token is a unique string that only you can generate — no one can guess or view invoices without the exact URL. The page also works on your whitelabel domain if you've configured one.
