Three entities, one Slack invoice
A retail group billed Slack through a single Hong Kong entity while seats lived in three subsidiaries. After Platform Billing Audit, they rebuilt the allocation key using workspace and channel ownership rather than headcount.
Outcome after two closes: clearer intercompany charges and fewer “why did IT grow?” emails. Limitation noted by their controller: the course did not automate the allocation — it only made the manual step defensible.
