Prompt given to every model
Z přiloženého dokladu vytěž údaje a vrať pouze JSON s těmito klíči:
supplier_name název dodavatele (přesně jak je na dokladu, včetně diakritiky a právní formy)
supplier_id IČO dodavatele
vat_id DIČ dodavatele
invoice_number číslo dokladu
payment_reference variabilní symbol
issue_date datum vystavení (YYYY-MM-DD)
tax_point_date datum uskutečnění zdanitelného plnění, DUZP (YYYY-MM-DD)
due_date datum splatnosti (YYYY-MM-DD)
net_by_rate základ daně podle sazeb DPH, např. {"21": 18450.00, "12": 1200.00}
vat_by_rate DPH podle sazeb, např. {"21": 3874.50}

Pravidla:
- Údaje odběratele nevracej, jen dodavatele.
- Pokud údaj na dokladu není, vrať null. Nic si nedomýšlej.
- Pokud doklad neobsahuje rozpis DPH (neplátce, zálohová faktura), vrať net_by_rate a vat_by_rate jako null.
- Částky jako čísla s desetinnou tečkou, bez oddělovačů tisíců a bez měny.
