Confirming both sides agree.
WHY IT IS NECESSARY
Integrations fail partially, and silent divergence is the usual result.
WHAT TO RECONCILE
Counts Totals, where amounts are involved Specific records, by identifier
WHAT FREQUENCY TO CHOOSE
Often enough that divergence is found before it compounds.
WHAT TO COMPARE
The source's view against the destination's, for a period.
WHAT TO REPORT
Records present in one and not the other Records differing in content Totals that disagree
WHAT TO DO ABOUT EACH
Investigate before correcting.
WHY
Correcting without understanding repeats the fault.
WHAT TO AUTOMATE
The comparison and the report.
WHAT TO ALERT ON
Any discrepancy, if discrepancies should be impossible.
WHY THAT PHRASING MATTERS
Some integrations legitimately lag, and the threshold must reflect that.
WHAT TO BUILD
A way to reprocess a specific record.
WHY
It is what you will need at three in the morning.
WHAT TO KEEP
Enough history to compare back to whenever the problem started.
WHAT TO RECORD FOR EVERY TRANSFER
What was sent, when, and what the destination returned.
WHY
Reconciliation without that record is guesswork.
WHAT THIS MATTERS MOST FOR
Anything financial.
