Which lender criteria changes should trigger an immediate routing review?

Credit, revenue, time in business, position, state, industry, funding range, product availability, and required document changes are material.

A changed negative-day, NSF, average-balance, or deposit-count tolerance can also alter an otherwise qualified file.

Submission email and portal changes matter operationally even when the buy box stays the same, because a file sent to the wrong place may never be reviewed.

What about a rate or term range change that does not affect basic eligibility?

Recheck pending comparisons and merchant expectations. It may not change eligibility, but it can change whether the proposed structure still fits.

The team should know the effective date and whether already submitted files are grandfathered.

A concise before-and-after note is much more useful than simply saying that guidelines were updated.

Keep the prior version and source. That prevents a later misunderstanding about which criteria applied when the file was submitted.

If the change is unclear, pause only the affected rule for manual confirmation instead of assuming every file is disqualified.

Review any change that can alter eligibility, structure, documentation, delivery, or the handling of an active submission.
