Service-specific questions
Can a POS system work across branches?
Yes. Branch, user, stock and reporting rules are designed from the operating model and connectivity conditions.
Can it work during internet outages?
Offline behavior is possible when explicitly designed with synchronization, conflict, security and recovery rules.
Do you support existing POS data migration?
Migration is assessed through data profiling, mapping, cleansing, reconciliation and rehearsal before cutover.
