Question & Answer
Question
Customer seeking clarity on how IBM Cloudability ingests Google Cloud Platform (GCP) billing data from BigQuery, specifically whether the ingestion occurs on a fixed daily schedule. The question arose while the customer was building automated reconciliation processes between their internal systems and Cloudability and observed small discrepancies even when applying a multi‑day delay to usage dates.
Cause
Cloudability documentation states that GCP billing data is ingested “up to 24 hours” after availability, but the customer needed to understand whether this implied a consistent daily ingestion time they could rely on. Without this clarity, their reconciliation jobs occasionally detected minor deltas in usage and cost figures, raising concerns about data accuracy.
The customer also noted that similar behavior had appeared across other cloud providers, suggesting this was not an isolated GCP-specific issue.
Answer
Cloudability’s ingestion of BigQuery-based detailed billing data does not run on a fixed clock-time schedule. Instead, ingestion depends on several upstream and downstream factors, including:
- Completion timing of the GCP export to BigQuery
- Discovery of new billing files
- Internal Cloudability processing jobs
- Cloud provider–side late adjustments or corrections
Because these steps are not time-synchronized, data for the same usage date may arrive at different times on different days. Additionally, cloud providers may retroactively adjust billing data after initial export, which can lead to small changes even days later.
The guidance:
- Do not plan reconciliation processes around a strict daily cut-off time
- Allow an appropriate reconciliation buffer when comparing datasets
- Expect minor deltas caused by provider-side corrections and normalization processes
- Distinguish clearly between usage date and ingestion completion time
This guidance applies not only to GCP but broadly across cloud providers such as AWS and Azure.
