SITUATION
Bill ₹1500 ka tha, patient ne ₹2000 diye (chhutta nahi liya) ya UPI me galti se zyada bhej diya.
OPTION 1 — ADVANCE: "Bill / Collect" → "Collect payment" me bill par ₹1500 aur "Add to advance" me ₹500 likho → "₹X received — record it". Bill ki row me due se zyada nahi likh sakte — app laal line dikhata hai aur Save band rakhta hai; extra hamesha "Add to advance" me hi jaata hai. ₹500 khate me jama rehta hai aur bill banne par sidebar ke "Apply to bill" se lagta hai. Patient ko batao aur receipt do.
OPTION 2 — WAPAS: extra usi waqt lauta do aur sirf ₹1500 darj karo (UPI me zyada aaya aur aapne extra wapas bhej diya to bhi sirf bill jitna, UTR ke saath). Chart me baad me refund karne ka button nahi hai, isliye jo bhi karo turant karo.
DHYAN
Cash me extra aaya aur na darj kiya na lautaya to Day End par cash zyada niklega.
