AWS/GCP invoice breakdown spreadsheet and client margin model — "Unable to accurately price client enterprise deals due to blended hosting costs"
Why the manual spreadsheet breaks financial controls and how a deterministic workflow replaces it.
AWS and GCP invoices are broken down in a margin workbook that spreads hosting cost evenly across clients because usage tags are incomplete.
Enterprise deals are priced on blended hosting rates, so unprofitable tenants are signed and profitable ones subsidize them.
Cloud-cost telemetry ingestion that attributes compute, storage, and egress to tenant tags and posts client-level cost into the margin model.
Attribution assertion: invoice cost must equal the sum of tagged tenant usage plus an explicit untagged residual, or the allocation cannot post.
Three-stage comparison between manual workbook reconciliation and automated rule-based execution.
AWS and GCP invoices allocated evenly because tenant tags are missing.
Unprofitable tenants are signed because hosting cost was never attributed.
Compute, storage, and egress post to client tags with an explicit untagged residual.
Invoice cost equals tagged tenant usage plus an explicit residual, or the allocation does not post.
