How do you switch banks without wrecking your books?
The clean way to switch banks is an overlap, not a cutover: open the new account and connect its feed first, move deposits and auto-payments over deliberately while both accounts run, reconcile the old account down to zero activity, and only then close it — with its final statement filed. The books treat it as two accounts with a handoff period, never a find-and-replace. Do it as an abrupt cutover instead, and you inherit broken feeds, orphaned auto-drafts, and a reconciliation gap right at the seam.
Investors hit this by choice — chasing better service or lending — and by force, when a bank gets acquired and accounts migrate on someone else's timeline. The playbook is the same either way; an acquisition just compresses it.
The overlap playbook
- Open new, connect first. New account opened, bank feed connected and proven, before anything moves. The new account is its own account in the books — never renamed over the old one, or both histories blur.
- Migrate the automatics on a list. Every deposit source (rents, platform payouts, tenant portals) and every auto-draft (mortgages, insurance, utilities, subscriptions) moves on a written checklist, checked off as each lands in the new account. The ones you forget are the ones that bounce.
- Run both, reconcile both. During the overlap — typically one to two statement cycles — both accounts reconcile monthly as usual. Transfers between old and new are transfers, not income or expense.
- Drain, verify, close. When the old account shows a full cycle of no activity, reconcile it one last time to a zero-drama final statement, download the statement history, and close it. Banks cut off online statement access fast after closure — pull the archive *before* the goodbye.
- Mark it, don't delete it. The old account stays in the chart of accounts, made inactive. Its history supports every past reconciliation and tax year; deleting or merging it vandalizes your own records.
When the bank is acquired out from under you
Acquisitions add three wrinkles: account numbers change (breaking feeds silently mid-month), statement archives move or vanish on the acquirer's schedule, and auto-drafts sometimes migrate themselves — or don't — without telling you. The moves that matter: download the complete statement archive the day the acquisition timeline is announced, treat the post-migration account as a new account in the books if the number changed, and audit the automatics list against the first post-migration statement line by line.
Why the seam is where books break
Almost every messy file we take on has a scar at a bank transition: a feed gap nobody backfilled, a month that never reconciled, an auto-payment that quietly failed and triggered late fees. The overlap period exists to make the seam boring. If the seam is already behind you and it's ragged, backfilling it from statements is standard catch-up work — statements are the backbone there too.
FAQ
How long should the overlap run?
One full statement cycle of zero activity on the old account is the finish line; for accounts with quarterly or annual drafts, keep a small balance parked until each has recurred once on the new account — that's how the forgotten ones surface.
Do I merge the old and new accounts in QuickBooks?
No. Two real-world accounts, two ledger accounts. Merging rewrites history and breaks every past reconciliation report. The old account goes inactive when it closes; its history stays.
What happens to the bank feed history when I close the account?
The feed stops, but booked transactions stay. What disappears is the *bank's* side — statement PDFs and login access. Download every statement before closing; you'll want them for taxes, audits, and any future catch-up.
My new bank's feed won't connect. Now what?
Run on statements until it does: enter or import from the monthly statement and reconcile normally. A missing feed is an inconvenience; an unreconciled month is a defect. (Feeds from smaller banks and credit unions misbehave regularly — the statement is always the truth anyway.)
