What the AI does with
your Fifth Third activity.
Connecting Fifth Third Bank isn't the finish line — it's the input. Here is what SuperBooks does with each transaction, and the one step that stays yours.
Every Fifth Third transaction syncs into SuperBooks through Plaid — read-only. We can see the money move; we can never move it.
Upload a receipt, then attach it to the Fifth Third transaction it belongs to. It stays linked from then on.
Each Fifth Third expense is sorted into a category you control, and the expenses-by-category report adds them up for your accountant.
Profit and loss, burn rate and runway are computed from your Fifth Third feed each time you open them, so they are never a month behind.
SuperBooks asks Plaid for up to 24 months of Fifth Third history the moment you connect — how much comes back is Fifth Third's call — so your first month starts with history already behind it.
Every currency,
kept as it happened.
Fifth Third posts in USD. Invoice a client in EUR or pay a vendor in GBP: each account, transaction and invoice keeps the currency it happened in, and your invoice totals convert to USD at the day's published rate.
One read-only link to set up.
Up to two years of history.
SuperBooks asks Plaid for up to 24 months of Fifth Third transactions and categorizes each one it is confident about.
We can't move your money.
That's by design.
Plaid handles authentication. We hold a read-only OAuth token and nothing else — your Fifth Third credentials never touch our servers.

Straight answers, each one true of SuperBooks as it ships today rather than as it is planned.
Does Fifth Third Bank work with Plaid?
Yes. Plaid's own institution page, listed as "Fifth Third Bank", shows it supported in the United States, for Assets, Auth, Balance, Transactions, checked 2026-09-27: https://plaid.com/institutions/fifth-third-bank/.
Can I connect Fifth Third Bank to QuickBooks or other accounting software?
SuperBooks has no QuickBooks connection: it is bookkeeping software itself, and it connects to Fifth Third through Plaid. To take those transactions into another tool, export them as a CSV: one file of the transactions you select, with a column naming the bank account each one came from.
Do I need a Fifth Third Bank API or developer key?
No. SuperBooks reaches Fifth Third through Plaid, read-only, and you connect with the Fifth Third login you already use, so there are no developer credentials to request from the bank. Your own data is then readable over the SuperBooks REST API, its TypeScript and Python SDKs, and its MCP server — on every plan.
How do I link my Fifth Third Bank business and personal accounts?
Sign in to Fifth Third through Plaid with the login that holds those accounts; SuperBooks then lists every account Plaid returns for it, and you choose which ones sync. All of them count as one bank connection on your plan. SuperBooks keeps one login per Plaid institution for each company — for Fifth Third, Plaid's "Fifth Third Bank" record — so connecting it again replaces that login instead of adding a second one. If your personal and business accounts sit under two separate logins there, only one of them can be connected at a time.
Does SuperBooks store my Fifth Third Bank login?
No. You sign in through Plaid — in Plaid's own window, or on Fifth Third's own site if Fifth Third uses OAuth — so your password goes to Plaid or Fifth Third, never to SuperBooks. The only credential SuperBooks holds is a read-only token for transactions and balances — it can never move money — and disconnecting Fifth Third revokes it.
How much Fifth Third Bank history comes across?
SuperBooks asks Plaid for up to 730 days — roughly two years — the first time you connect. How much of that actually arrives depends on what Fifth Third makes available through Plaid.
Does SuperBooks categorize Fifth Third Bank transactions automatically?
Yes, when it is confident. SuperBooks applies a category above a 0.7 confidence score; below that it writes nothing rather than guessing, so the Fifth Third transaction stays uncategorized in your list until you set it.
Can I export my Fifth Third Bank transactions?
Yes — your transactions export as a CSV on every plan and from every role, so you can hand Fifth Third activity to an accountant or load it into another tool whenever you want.
What does connecting Fifth Third Bank cost?
Nothing to start: the free plan includes 1 bank connection and takes no credit card. Starter raises that to 3 connections and Pro to 10.
