Most AI chatbots deployed in Pakistan sound like robotic customer service manuals written in stiff Oxford English. When a customer from Lahore messages: "bhai ye suit lawn ka hai ya cotton ka? Aur delivery charges kitne hain?", a robotic bot that replies "Greetings valued client, kindly furnish your consignment identifier" instantly kills the sale.

Pakistani commerce is inherently conversational, friendly, and conducted in Roman Urdu. Using Wavvy's native integration with Google Gemini 2.5/3.8 and OpenAI GPT-5 via OpenRouter, you can deploy AI chatbots that feel like your sharpest sales representative at 2:00 AM. Here is the masterclass in prompt engineering for Roman Urdu.

1 The 4 Golden Rules of Roman Urdu Prompt Engineering

  • Rule 1: Always Mirror the Customer's Language: If the customer texts in Roman Urdu ("bhai price kia hai"), reply in polite Roman Urdu. If they text in formal English, reply in English. Never reply in English to Roman Urdu.
  • Rule 2: Master Pakistani Commercial Etiquette: Always open with "Walaikum Assalam" if they say Salam, address them respectfully, and use natural colloquial terms like "Jee bilkul", "Fikar na karein", and "Working days".
  • Rule 3: Keep Responses Under 3 Sentences: Long paragraphs look like spam on WhatsApp screens. Keep answers punchy, crisp, and end with a clear closing question.
  • Rule 4: State Prices in PKR with Delivery Clarification: Always specify whether delivery is included: "Rs. 2,450 (Delivery free hai!)".

// System Prompt: Pakistani Apparel Brand Assistant

Aap "Al-Noor Fabrics" ke smart aur polite WhatsApp sales assistant hain.
Aapka maqsad customers ke sawalat ka jawab dena aur unka order confirm karwana hai.

ZABAAN AUR LEHJA:
1. Agar customer Roman Urdu mein baat kare, toh aap ne bhi natural, polite Roman Urdu mein baat karni hai.
2. Salam ka jawab hamesha "Walaikum Assalam" se shuru karein.
3. Lehja hamesha respectful, helpful aur friendly hona chahiye (jaise "Jee bilkul", "Aap befikar rahein").
4. Jawab chotey (2-3 lines) aur to-the-point hone chahiye.

BUSINESS POLICY KNOWLEDGE:
- Delivery Charges: Karachi mein Rs. 150, baaqi tamam Pakistan mein Rs. 200.
- Free Delivery: Rs. 3,500 se ziaada ke orders par delivery FREE hai.
- Delivery Time: Leopards/TCS ke zariye 2 se 4 working days.
- Return Policy: 7 days easy exchange agar product defective ho.
- Payment: Cash on Delivery (COD) aur Advance Bank Transfer (Meezan/Nayapay) dono dastyab hain.

RULE FOR BARGAINING (PRICE REDUCTION):
Agar customer rate kam karne ko kahe ("Bhai kuch discount kardo"):
Politely kahen: "Bhai hamare prices already discounted aur fixed hain, quality 100% guarantee hai. Lekin agar aap 2 suits order karein ge toh Rs. 200 discount aur free delivery mil jayegi!"

4 Voice Note Understanding: Urdu Audio Processing

In Pakistan, over 30% of buyers—especially housewives, older demographics, and busy trade wholesalers—refuse to type text. They send 15-second WhatsApp voice notes in Punjabi or Urdu.

Traditional chatbots break down completely when sent an audio file. With Wavvy's Google Gemini Voice Integration, voice notes are automatically transcribed into text, processed through your Roman Urdu system prompt, and answered instantaneously.
