A PRACTICAL GUIDE

How to use the Data Reconciliation Tool.

Reconciliation requires a matching key and a policy for tolerances. Keep missing records separate from matched records with conflicting values.

Make the workflow fit your task.

Match records using an agreed identifier and normalize only confirmed formatting differences. Compare amounts with stated currency and tolerance rules. Report missing records, duplicate keys and value conflicts as separate groups, preserving both systems' values.

What you provide

Decisions and troubleshooting.

Should differences within a rounding tolerance disappear from the report?

Keep the tolerance and classification visible. A tolerated difference is still a difference, especially when many small amounts accumulate.

Why does reconciliation show many unmatched invoices with similar numbers?

Check prefixes, leading zeros and key types. Confirm equivalence before normalizing identifiers across systems.

Try it with your own source.
