Our goal is to help independent stores keep selling and keep their records under their own control, even when the connection is unavailable.
Keep products, sales, stock, staff, and accounting records on the store device.
Move a catalog or full workspace with clear restore files when a device changes.
Build clearer sales, financial, payroll, and multi-store summaries without hiding local history.
Continue improving hardware setup, guided learning, staff workflows, and store-to-store tools.
