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.

• If a shop's web address is reused by a new shop, this phone never shows the previous shop's data.
• Home's date and today's totals now roll over at midnight (Bangladesh time) even if the app stays open.
• Quick quantity: tapping a product opens one sheet to pick the unit and how many. Its button shows the line total before you add, and you stay on search, with Undo and Edit just below it.
• Type a number before the product name ("3 …") to search with that quantity already filled in.
• Tapping a product already in the cart adds one more of the same unit; a long-press sets any quantity.
• Product tiles show stock and price in the unit a tap sells.
• A product with no stock is not added: receive stock first.
• Receipts: the printed slip (58 mm and 80 mm) and the A4 invoice show the customer's name when a customer is added to the sale, reprints included.
