What every sync guarantees
Section titled “What every sync guarantees”- No double posting — each day (or each POS sale) is recorded once, even if a sync runs twice.
- Balanced entries — every posting debits and credits equal amounts; the tax collected goes to the tax account and appears on your tax report.
- Reversible re-syncs — re-syncing a day reverses the earlier entry and posts a fresh one; nothing is edited in place.
- Period locks apply — a sync cannot post into a locked fiscal year.
