What does “multi-tenant” actually mean here?
AtelierSuite runs as one carefully partitioned system rather than a separate copy per house. Every house — every tenant — has its own space inside it: its own staff, clients, commissions, cloth, diary, papers, invoices and settings.
The advantage of one system is that every house gets the same maintained, patched, backed-up software on the same day, instead of an ageing private copy nobody has looked at in a year. The obligation that comes with it is separation, and that is the part we treat as the product's foundation rather than a setting.
