Reclass vs. correction

A reclass moves an amount between accounts (e.g., from Office Supplies to Software). A correction changes the amount. Document both with a memo so a reviewer can follow the trail.

Never edit closed periods

If you find an error in a closed month, book a correcting entry in the current period and disclose it. Editing closed books destroys audit history and credibility.

Materiality

Not every mistake is worth fixing. A $4 miscategorization on $200k of monthly expense is noise. Set a materiality threshold and stick to it.

Key takeaways

  • Reclasses move, corrections change amounts — document both.
  • Never edit closed periods; correct in current.
  • Set a materiality threshold to avoid busywork.
