Works with QuickBooks

Validate customer data inside QuickBooks

Check a customer's email, phone number and billing address on the QuickBooks record you already have open — one click, same tab. Catch the bad address before the invoice goes out, not when it comes back.

50 validations a month, free forever. No credit card.

Bad contact data costs you quietly

Nothing errors out. The invoice just never arrives, the reminder goes to a dead inbox, and the payment slips another month.

Invoices that come back

An undeliverable billing address is a payment delayed by weeks — and you find out from the returned envelope, not from your books.

Reminders that never arrive

A dead email address means your payment reminder was never read. The customer isn't ignoring you; they never got it.

Numbers you can't text

An SMS sent to a landline fails silently. No bounce, no warning, no reply — and no way to tell it apart from being ignored.

How it works

Client Validator is a Chrome extension. It reads the record on your screen — so there is no QuickBooks app to install, no API key to configure, and no admin involved.

1

Open a customer record

A customer, in the normal QuickBooks customer detail view.

2

Click the extension

It finds the email, phone and address fields on the page and reads them.

3

Read the result

Each field comes back verified, flagged, or corrected — with a confidence score.

What gets checked

One record, one validation — whether you fill one field or all three.

Email verification

  • Spam trap detection
  • Inbox full & bounce prevention
  • Invalid format & fake account detection
  • Accuracy confidence scoring

Phone validation

  • Caller ID lookup (US & Canada)
  • Carrier lookup (US & Canada)
  • Landline vs mobile for SMS/MMS
  • Format correction & cleansing

Address intelligence

  • USPS delivery-point verification (US)
  • Building-level verification in Canada & Australia
  • Residential vs commercial indicators
  • Deliverability confidence scoring

Questions

Do I need to install anything in QuickBooks?

No. Client Validator is a Chrome extension that reads the record displayed in your browser. There is no QuickBooks app to install, no API key to paste into QuickBooks, and no admin permission required.

Does it change my QuickBooks data?

No. It reads the fields on screen and reports back. Any correction is yours to apply — nothing is written to your records automatically.

What counts as one validation?

One record. Whether you check just the email or the email, phone and address together, that is a single validation. If every check fails on our side, the credit is refunded.

Which countries are covered?

Address validation covers the United States, Canada and Australia. Phone validation covers the United States and Canada. Email verification works worldwide.

Can I check a whole list at once?

Yes, on the Professional plan and above. Bulk validation takes a CSV export and returns the same checks across every row.

Does it work with other tools?

Yes. The extension reads how a page is structured rather than targeting one vendor, so it works across CRMs, schedulers and billing tools. QuickBooks is one of the platforms we test against directly.
