To change the style of your PDF invoices:

1. Go to Settings → "Factuurontwerp" (invoice design)
2. Click "Genereer uit huisstijl" for a design in your own brand colour, or pick one of the style presets
3. Fine-tune the accent colour, paper tint, fonts, layout and footer text; the A4 preview updates live
4. Changes save automatically and apply to all new invoices, quotes and reminders

Tip: your logo and brand colour live under Settings → "Logo en kleur"; the design studio builds on them.

Tip: when you are viewing an invoice or quote, click Change design in the document preview header (or in the overflow menu on mobile) to jump straight to Factuurontwerp. After you finish editing, you return to the document you came from.
