Update linked bank account

My payroll deposit failed. Update my linked bank account to the business account at First National, IBAN IT60X0542811101000000123456, account name Lumen Studio, and set it as the primary payout source before noon Thursday so the next payout goes to that account.

Before I switch the payout to the new bank, make the change low-risk: surface whether any pending payouts will still go to the old account, list the verification steps and expected hold time, and flag anything that could delay funds (mismatched account name, unverified microdeposits, or required ID).

I just added my business account at First National and set it as primary, but the next scheduled payout still lists the old account. I’m worried the payroll will hit the wrong account and cause a client refund or missed vendor payment. I don’t know if the new account needs verification or if there’s a hold. What likely caused this and what should I do now to ensure the upcoming payout goes to the new account?

Over the past year I’ve changed linked bank accounts three times and each change cost me a delayed payout or an extra reconciliation day. Where am I losing time—on verification steps, timing of payouts, or not scheduling changes—and what consistent habit or checklist should I adopt so switching accounts never risks missing a payroll or vendor settlement?
