GadgetOS is the offline-first operating system for Bangladeshi electronics and gadget shops — counter POS, serial/IMEI-tracked inventory, warranty + RMA, EMI instalment sales, trade-in/buyback intake, and Mushak 6.3 VAT receipts from one iPhone or iPad. SERIAL & IMEI TRACKING, UNIT BY UNIT Every phone, laptop and accessory unit is received with its serial/IMEI. Sell a specific unit, not just a quantity — warranty and RMA history stays attached to it. SPEC CATALOG BUILT IN Adopt phones, laptops and gadgets from the built-in electronics catalog — brand, model, variant (processor/RAM/storage), spec sheet and photos prefilled. WARRANTY + RMA, EMI Warranty terms print on the receipt; track claims from intake to resolution. Configure EMI tenures and record instalment plans at the counter. TRADE-IN / BUYBACK, DOCUMENTED Structured used-device intake with photos, seller KYC and phone verification — a clean paper trail for every used unit you buy. COUNTER POS THAT NEVER STOPS Ring up a sale even with the internet unplugged; sync resumes in the background when connection returns. MUSHAK 6.3 RECEIPTS OUT OF THE BOX Sequential sale numbers per branch per fiscal year (July–June), itemized VAT, BIN + TIN + Asia/Dhaka timestamp. Monthly NBR export in one tap. PAYMENTS Cash, bKash, Nagad and card — counter QR + trxID entry, merchant gateway credentials, monthly reconciliation. BENGALI FIRST Toggle Bengali/English instantly; receipts print in proper Bengali Unicode. PRIVACY & DATA Your store's data is scoped to your business with enforced per-tenant access controls, encrypted at rest and in transit. No third-party analytics.
