Hey Product Hunt — I'm the maker of InvUltra. I built this for shop owners who lose a sale the moment Wi-Fi drops. The customer is at the counter, checkout spins, and the sale is gone. Most POS tools treat offline as a fallback. InvUltra writes the sale on the device first, then syncs when the connection comes back. It is one installable app for the counter and the back office: barcode checkout, hold orders, thermal receipts, inventory, purchase orders, invoices and quotes, customer balances, loyalty, register day-close, reports, and an activity log so the owner can see who changed a price, a discount, or stock. Who it is for: single shops on the Professional plan, and multi-store teams on Enterprise (branch stock, transfers, store-scoped reports). Try it: 7 days, every feature, no credit card. https://web.invultra.com/register I would love feedback from anyone who has run a counter on a bad connection. What breaks first for you when the internet drops — checkout, stock, or the end-of-day cash count?
