Why numbers differ between Viewnex and the ad platform

Sync timing, attribution windows and time zones explain almost every mismatch.

3 min readUpdated August 21, 2026

  • 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.
