Split bills v3

Workflow

1. Decide the input mode.
   • Structured JSON already known: pass the JSON directly.
   • Natural language in English or Bahasa Indonesia: pass the text directly.
   • Bill photo provided: pass the image as receiptImageDataUrl, receiptImageBase64, or receiptImageUrl. The skill will try OCR first, then run the same accounting engine on the extracted receipt lines.
2. Let scripts/split-bills.js be the single accounting engine.
3. Ask one short follow-up instead of guessing when people or item ownership are still missing.

Call run_js

Use these exact parameters:

• script name: index.html
• data: one of:
  • a JSON string, or
  • a plain-text multiline bill description

Supported JSON fields

• people: array of person names
• items: array of objects with:
  • name: string
  • amount: number
  • assignedTo: array of person names
• text: optional natural-language bill notes in English or Bahasa Indonesia
• ocrText or receiptText: optional receipt lines, either user-provided or produced by OCR
• receiptImageDataUrl, receiptImageBase64, receiptImageUrl: optional bill image inputs for OCR
• currency: optional ISO currency code, defaults to IDR
• language: optional en or id
• discountPercent, discountAmount
• servicePercent or serviceChargePercent
• serviceAmount or serviceChargeAmount
• taxPercent, taxAmount
• tipPercent, tipAmount
• rounding: optional rounding increment such as 500 or 1000
• paidBy: one person paid the full total
• payments: explicit per-person payments that must sum to the grand total

Supported text patterns

People

• people: Ayu, Budi, Citra
• orang: Ayu, Budi, Citra

Item lines with amount

• Ayu had nasi goreng 60000
• Ayu makan nasi goreng 60.000
• Budi and Citra shared sate 90000
• Budi dan Citra patungan sate 90.000
• Es teh 30000 for all
• Es teh 30.000 buat semua

OCR receipt lines

Use these when a bill photo was transcribed first:

• Nasi goreng 60000
• Sate 90000
• Es teh pitcher 30000
• Pajak 10%
• Service charge 5%
• Diskon 20000

Then optionally add ownership or payer lines:

• Ayu makan nasi goreng
• Budi dan Citra patungan sate
• Es teh pitcher buat semua
• Ayu bayar semua

Payment lines

• Ayu paid all
• Ayu bayar semua
• Budi paid 50000
• Budi bayar 50.000

Totals and adjustments

• Tax 10%
• Pajak 10%
• Tip 5%
• Discount 20000
• Diskon 20.000
• Voucher 10%
• Service charge 5%
• Biaya layanan 7,5%
• Round 500
• Pembulatan 1000

Important rules

• Use paidBy for the common one-payer case.
• Use payments when multiple people already paid.
• Do not provide both at once.
• Rounding is only a suggestion layer on top of exact accounting; totals must remain exact.
• Discounts are applied before service charge, tax, and tip.
• Service charge is added before tax and tip are calculated.
• For receipt OCR, preserve uncertainty instead of inventing values. Ask one short follow-up if the image text is still unclear.
