Lab ke saath desi khata system built-in hai — par sirf un vendors ke liye jo ORALAB lab se linked hain (vendor row par 🔬 ORALAB ✓ badge).
Khata dekhna:
- Sidebar → Practice → Lab → 'Lab Vendors' tab kholo.
- Linked lab ke saamne 📒 Khata button dabao — modal me Total billed, Total paid, Outstanding chips + poori ledger (date, type, ref, debit, credit, running balance) dikhti hai.
- Agar udhaari limit cross ho gayi to red warning dikhti hai: '⚠️ Udaari limit cross — ₹X baaki, sabse purana Y din' (credit-lock system).
Payment karna (zero gateway fees — paisa seedha lab ki UPI par):
- 💸 Pay button dabao (ya Khata modal me '💸 Pay karo — ₹X baaki').
- Amount daalo (outstanding pre-filled hota hai) — lab ki UPI ID + QR code + '📲 UPI app kholo' link dikhega. Phone se QR scan karke ya UPI ID par paise bhejo.
- Payment ke baad UTR/reference number daalo, mode chuno (UPI / bank transfer / cheque / cash / other) aur '✅ Maine bhej diya' dabao.
- Claim lab ke ORALAB Books inbox me jaata hai — lab confirm karte hi khata FIFO settle hota hai (purane invoice pehle). Claim status yahi modal me dikhta hai: ⏳ Lab confirm karega / ✅ Confirm — settle / ✗ Reject (reason ke saath).
Edge cases:
- Lab ne apni UPI ID set nahi ki? Modal bata dega — lab ko bolo ORALAB me Settings → Billing me UPI daale. Tab tak bank transfer karke reference daal sakte ho.
- Duplicate UTR server par dedup hota hai.
- Kisi bhi vendor (non-ORALAB bhi) ka monthly charges statement 📄 Statement button se milta hai — har case ki lab charge ek saath verify karo.
Mobile app me bhi same khata + pay flow hai (Lab Orders screen me Khata modal).
