I build point-of-sale, attendance and operations systems that write every transaction to the device first — and reconcile with the server the moment the signal comes back.
One front door for eight apps at the UIR Faculty of Law — exam attendance, lecture registers, special classes, grades, student data and news publishing — at one address behind one login.

In Pekanbaru the internet can drop right in the middle of the dinner rush. A cloud cashier that refuses orders when the signal goes isn't malfunctioning — it was designed that way. So every POS I build writes the transaction to the device first and reconciles with the server when the line comes back.
My systems are currently in use at the UIR Faculty of Law and for dissertation research. The cashier, attendance and service projects I built independently — and they're ready to be adapted to your business.
