🎟 Coupons (sirf owner): flat ₹ ya % code; rules — Valid From / Valid To, "Min Bill Amount (₹)", "Max total uses (0 = unlimited)", "Max uses per patient", "Max ₹ discount (cap for %, 0 = no cap)" aur "Redemption cap (% of bill)" (default 50% — ek coupon bill ka aadhe se zyada nahi kaatta). "Yearly Generator" ek saath bahut saare random flat-₹ code banata hai (CSV download). "Staff Report" batata hai kis staff ne coupon se kitna discount diya. Coupon box patient chart ke "New bill" drawer me nahi hai.
🎁 Gift Cards: becho = "Face value ₹", "Paid by (patient)", "Paid how", recipient naam / phone (WhatsApp par code), expiry (khaali = 1 saal); code GC-… se shuru. Redeem = code → "Look up" → "Use on whose bill?" patient → bill → "Amount to redeem" → "Redeem on bill"; bacha balance card par rehta hai. Mobile app me gift card sirf look up / redeem hota hai.
Fark: coupon = discount (paisa kam liya); gift card = pehle liya hua paisa, baad me bill me jama.
