ZF System is a cloud-based management system for optical stores and optical labs. It integrates point-of-sale, service-order management, inventory control, credit and financing, electronic invoicing, and online sales — without local installation. The platform automates backups and updates. Service orders store prescription details, lens specifications, PD/DNP measurements, and order status from sale to delivery. Inventory tools include stock alerts and barcode labeling. The credit system supports customizable financing plans with automated reminders. Additional features include virtual try-on, mobile pupillary-distance measurement, receipt recognition via messaging apps, and synchronization of inventory and orders across e-commerce and social channels. ZF System integrates payment gateways, shipping providers, and AI customer-service tools, supporting single or multi-location optical stores.
