The problem

When two systems show different numbers, people stop trusting both. Most gaps have an ordinary cause, like a different date field, a hidden filter or a time zone. Data Validation finds it and shows what it ruled out.

What you get back

The verdict

Whether you can trust the Foureyes number for what you're using it for.

Gap table

Your number, the Foureyes number, the gap, the reason, and how sure it is: confirmed, likely, or not explained.

Shape of the gap

When and where the difference shows up.

Ruled out

Causes it checked that weren't the reason.

Next step

If it looks like a setup problem, a note you can send your Foureyes contact.

Unmatched records

CSV files of records on one side only, if you gave a list.

How it works

1

You give the number and where it came from. It asks up to four questions about the report, each with a default.

2

It pulls the same number from Foureyes, adding your report's filters one at a time.

3

If you gave a list, it matches record by record.

4

It checks the likely causes in order and tests its answer before reporting.

Try this first

Foureyes shows [number] internet leads for [store] last month, but our CRM shows [number]. Why?

Claude says what it will do and asks a few questions about your report, then returns a table of gaps with reasons.

More questions to ask

  • We're missing leads. Why?
  • Reconcile this customer list

Good to know

  • Accepts CSV, Excel, PDF and screenshots.
  • Compares your own data only.
  • Files of unmatched records contain real customer data.
  • It can't explain records Foureyes never received, but it can show the pattern for your Foureyes contact.

Test before you rely on it

Bring the report name and its filters. Most gaps come from there.
