How to Switch Business Bank Accounts
30-Day Migration Checklist + Multi-Account Setup

A careful migration takes 30 days from opening the new account to deactivating the old one. The first 7 days cover opening and testing the new account. Days 8-21 cover updating all payment integrations and accounting feeds. Days 22-30 cover recurring vendor payments. Day 30 schedules the old account closure 60 days forward -- giving you a two-month buffer to catch any payers or autopays that were missed in the initial sweep. Trying to do this in less than two weeks risks bounced ACH transactions, missed payroll runs, and disrupted Stripe payouts.

Several things can break if you close the old account before all payors and payees have switched. First, pending merchant services reversals and refunds may be issued to old card numbers and routed to the closed account -- creating a dispute resolution process. Second, some recurring billers (utilities, insurance, software subscriptions) take 1-2 billing cycles to update after you change the autopay details -- if the old account is closed, the ACH debit returns as insufficient funds and may trigger service interruptions or late fees. Third, 1099-K reporting mismatches can occur if Stripe or Amazon issues a 1099-K to your old account information.

In the Stripe Dashboard: Settings > Bank accounts > Add bank account. Verify the new account with microdeposits (2-3 business days) or instant verification via Plaid. Once verified, set it as the default payout account. Stripe will continue to pay out to your old account for any payouts already scheduled. After switching, monitor that the old account receives no new Stripe payouts. Keep the old account open for 60 days to catch any delayed reversals or refund credits.

Most sophisticated business owners benefit from 2-3 purpose-specific accounts. The Profit First methodology recommends 5 accounts: Income (all revenue lands here), Operating Expenses, Owner's Pay, Tax, and Profit. Relay's 20 sub-account architecture replicates this within a single banking relationship -- you get all the Profit First benefits without the complexity of managing five separate institutions. For businesses that use a traditional bank for cash handling plus a fintech for daily operations, two institutions is common and manageable. Beyond three institutions, the administrative overhead typically outweighs the marginal benefit.

For Gusto: go to Settings > Banking in your Gusto admin and update the bank account for both the payroll funding pull and any employee direct deposit return items. Gusto requires verification (microdeposits or instant verification) before switching the funding account. Make the change at least 5 business days before the next payroll date -- Gusto pulls funds 4 days before payroll for standard speed. For ADP: contact your ADP representative or use the self-service bank account update in your ADP portal. Allow 1 full payroll cycle for the change to propagate. Do not close the old account until you have confirmed at least 2 payroll runs have processed cleanly from the new account.

Profit First (developed by Mike Michalowicz) is a cash management method where you allocate incoming revenue to purpose-specific accounts immediately upon receipt, rather than tracking against a budget. The five core accounts: Income (100% of revenue), Operating Expenses (30-50% swept), Owner's Pay (15-35% swept), Tax Reserve (15-25% swept), and Profit (5-10% swept). The percentages are adjusted over time as the business grows. Relay's 20 sub-accounts within one login make Profit First implementation straightforward -- you set up each envelope and move money between them without logging into multiple banking portals.
