Commercial groups
Invoice at the chain level, deliver at the store level.
When you work with a national chain, you deliver to several distinct stores but often invoice the central purchasing office. OstraOS models this structure with commercial groups, which gather a parent (the chain) and its children (the stores).
The "Bill to group" option
If the option is enabled on a store, its invoices and purchase orders automatically use the parent group's address and billing details — not the individual store's. Resolution is handled by OstraOS with no manual step.
Group-level credit notes
Commercial gestures negotiated at chain level (a global quarterly credit, for instance) can be entered directly at group level. They stay available to apply on any invoice from any store of the group.
Tip
If a client has no parent group, the "Bill to group" option is greyed out. No risk of enabling it by mistake.
