2. Parties: Full details for sender and recipient
3. Items/Services: Descriptions, quantities, rates
4. Calculations: Tax rates, discounts, totals
5. Terms: Payment due date, validity period
6. Branding: Colors, style preferences, logo
7. Additional fields: PO numbers, project references, notes

Example Prompt Structure

"Create a [document type] #[number]
From: [company name and details]
To: [client name and details]
Items: [list with quantities and prices]
Tax: [rate and type]
Terms: [payment terms]
Style: [design preferences]"

Mode Selection

Ask your users before generating:

"Do you want fast & cheap, or high quality?"

Mode	Best For	Speed	Quality
max	Final client-facing invoices, branded documents	Slower	Highest
eco	Draft invoices, internal documents, bulk generation	Faster	Good

Error Handling
