Why Historical Revenue Metrics Can Change

Why past revenue numbers can change

Sometimes revenue numbers (like MRR or ARR) change even for past dates. This is normal and usually means the data is more accurate, not wrong.

The most common reasons

1. Data arrived late Some billing data comes in after the fact (for example, when a new billing system is connected or an old subscription is backfilled). When it arrives, past numbers update.

2. Data was corrected Subscriptions or payments may be fixed or edited later (in the billing system or in Bigdelta). When corrected data is synced, past revenue updates to match.

3. Data hadn’t synced yet Payments may exist in your billing system but haven’t synced to Bigdelta yet. Once they sync, Bigdelta updates past revenue using the original payment time.

4. Accounts were reorganized Customers may be merged, linked, or reclassified. Revenue may move between customers, even though total revenue stays the same.

Snapshots vs. live numbers

• Snapshots: what the number looked like at that moment (old exports or screenshots)

• Recomputed metrics: numbers recalculated using the latest data Bigdelta mainly shows recomputed, source-of-truth numbers, so they may differ from old snapshots.

What to remember

• Small historical changes are expected

• Changes usually mean better data quality

Key takeaway: Historical revenue numbers are living numbers. When they change, it usually means the data is more complete or corrected—not unreliable.
