Barcode POS for mini-marts
Barcode checkout for Ghana mini-marts: scan fast, MoMo on the sale, website from the same stock.
Scan the product the shelf already uses
Scanning on the POS in the browser, or on POS Desktop, is what moves a mini-mart queue. Typing the price at peak hour slows the line, and a slow line loses sales.
MoMo uses the same product list
Take MoMo on the sale the scan opened. Cash, MoMo, and card then close on one shift. If the MoMo prompt never reaches the POS, the drawer and the phone will show different numbers.
Pickup sells the scanned stock
Publish the same products to the website. When a pickup or rider order is done, that sale takes from the same stock the POS sells. Branch levels show whether another shop still has the product. Transfers between branches need internet.
Keep selling when the network is down
POS Desktop keeps cash sales, and MoMo you enter by hand, through a power cut, then uploads when the network is back. The POS in the browser and a live MoMo prompt need a connection. Do not edit the same product on two devices while the mart is offline.
