Your CFO needs a single revenue number; your accountants need country-specific books. Both views ship with Billing.
Consolidation currency
Pick a reporting currency at the tenant level (typically USD or EUR). Each entity's invoices convert at the FX rate stamped on the document — not at today's rate. That makes historical reports stable.
Eliminations
If two of your entities invoice each other (intercompany), the consolidated view subtracts those. Tag intercompany invoices on issue; the report does the math.
Statutory exports
Per-entity exports remain in the local format: CFDI XML pack for MX, NF-e batch for BR, Facturae bundle for ES. Your accountant gets what their software expects.
Segments
Slice the consolidated view by product line, billing entity, or currency. Useful for board reporting where you want "ARR in USD across all entities" but also "MX revenue YoY".
