LKG for Billing - Billing, hotel, clinic & pharmacy one app, multi-country tax

Hey Product Hunt! 👋 So excited to share LKG for Billing with you today — this is our full launch. 🚀 I built it because most small businesses end up running two or three tools — one for invoices, one for their front-of-house, and a third for their actual workflow. LKG bundles them all into one app, with proper regional tax baked in. 🧾 🌍 Multi-country tax — pick your region or define your own: - 🇮🇳 India GST · 🇬🇧 UK VAT · 🇺🇸 US Sales Tax · 🇸🇬 Singapore GST · 🇲🇾 Malaysia SST - 🧮 Auto tax split (CGST/SGST, State/Local, Sales/Service) - 📊 GSTR-1 / 3B reports; e-invoice portal integration coming soon 🩺 Clinic & Pharmacy module — for doctors, hospitals, and pharmacies: - 👥 Patient directory + consultation form with vitals, rich-text complaints and doctor's notes - 💊 Per-medicine dosage: Morning / Afternoon / Night, "Every N hours", before/after/with food, duration, and notes - ✅ Prescription → pharmacy approval flow that auto-creates an Invoice draft on approval - 📂 Patient detail page with full consultation history and a lab-reports / scans archive - ☁️ Document storage on Azure, S3, or local — your choice — with one-click Google Drive sync for offline-first clinics 🍽️ Hotel & restaurant module: - 🪑 Tables, kitchen dashboard, and order tracking - 📲 Take-order workflow built for the front of the house 📦 Plus everything you'd expect from a billing platform: - 🧾 Invoices, estimates, delivery challans, purchase orders, receivables, accounting - 🛒 Inventory with FIFO / LIFO / Weighted Average - 👤 Customer & product management - 🌐 29 languages - 💻 Web + offline desktop (Windows / Mac / Linux); 📱 fully responsive — every feature works in a mobile browser with adaptive rendering, no separate app needed - 🏢 Multi-tenant, multi-business - 👥 Multi-user included in every plan; 🐳 self-hosted and Docker available 🎁 Free 30-day trial, no credit card. Would love your feedback — especially from clinics, pharmacies, hotels, or anyone running a business across regions. What's missing for you? Drop a comment 💬
