Why numbers differ between Viewnex and the ad platform

• Sync timing — Viewnex refreshes on a schedule, so the last few hours can lag
• Attribution windows — platforms credit conversions over different periods
• Time zones — an ad account's reporting day may not match your local day
• Restatements — platforms revise recent figures after filtering invalid traffic

For accounting, always use the ad platform's own billing records as the source of truth for spend.
