A POS that works at the counter, on the street, and offline. Every sale deducts inventory and invoices instantly.
Lumon's point of sale turns any tablet, phone, or computer into a register that's ready to sell. Built for shops, restaurants, pharmacies, and service businesses that need to charge in seconds without fighting the system. Every sale is tied to your inventory, your treasury, and your electronic invoicing.
Cash, card, SPEI or Transfer365 transfers, and split payments on a single ticket. Change, tips, and rounding are calculated automatically. You close the register with a balanced count.
The POS saves sales on the device when there's no connection and syncs them when the signal comes back. You never lose a sale because of the wifi. Ideal for street markets, fairs, and spots with unstable internet.
You hand over a printed or digital receipt on the spot and, if the customer asks for an invoice, you generate it from the same sale. In Mexico you stamp CFDI 4.0 with the SAT; in El Salvador you issue the DTE with Hacienda.
No double entry: when you charge, the product leaves inventory and the system warns you when something is about to run out. You sell by barcode, by search, or from quick buttons for your best sellers.
Manage several registers and stores with independent prices and inventories from one panel.
Apply BOGO, percentages, wholesale prices, and coupons right on the ticket.
Each seller logs in with their own user and their close-out stays separate and traceable.
Process returns and credit notes, putting the product back into inventory.
Leave sales on credit or tab with payments and WhatsApp reminders.
Connect a thermal printer, cash drawer, scale, and scanner without installing weird software.
Start charging today with a POS that deducts inventory and invoices on its own.
