POS Software questions from Rio de Janeiro

Does Posnic handle ICMS in Brazil?

Posnic uses configurable tax groups, so ICMS rates are set once and applied automatically, with inclusive or exclusive pricing and tax-wise report summaries.

What hardware do I need to run Posnic in Rio de Janeiro?

Any Windows computer. Standard USB barcode scanners, thermal receipt printers, cash drawers, weighing scales and touch screens all work. Existing hardware from a previous system usually carries over.

Can I manage several stores in Brazil with Posnic?

Yes. Each store runs its own offline Posnic, and Posnic Cloud syncs them with branch-level access control and consolidated dashboards you can watch from anywhere.
