Build a new Treasury integration with Fifth Third BankBeta

This guide describes how to get started with Stripe Treasury using Fifth Third Bank.

Before you integrate

Test mode

You can request access to use test mode immediately. Test mode operates independently of any specific bank partner.

Before you create financial accounts in live mode for your Treasury integration, we recommend that you create test financial accounts in test mode. Test mode financial accounts can’t receive or send real money, and don’t generate a live account with real routing and account information, but are otherwise identical in configuration and functionality.

If you create an Account object in test mode and want to bypass onboarding requirements to test functionality, use POST /v1/accounts/{{CONNECTED_ACCOUNT_ID}} to provide test values that fulfill all the requirements.

Complete compliance reviews and update disclosures

To access Fifth Third in live mode, you must first submit evidence of the following to Stripe’s compliance team for approval:

• Any live or planned UX, or marketing that names a bank partner
• Any mentions of FDIC pass-through insurance eligibility
• UX including user balances with disclosures, bank statements, and transaction history

You must send previews of your planned updates using the Compliance Intake Form. After Stripe’s compliance team completes the review, we’ll grant you access to Fifth Third in live mode. Then, you can publish your approved disclosures.

You must follow all of the Treasury compliance guidelines, including regulatory receipts, complaints, and marketing guidelines.

Bank partner disclosures

You must include proper disclosures that funds are held with Fifth Third Bank. You must include disclosures on marketing assets, landing pages, other websites, dashboards, social media posts, or any other interface that references Stripe Treasury.

Make sure that your disclosure reads: “[Company Name] partners with Stripe Payments Company for money transmission services and account services with funds held at Fifth Third Bank, Member FDIC.”

FDIC pass-through insurance eligibility disclosures

In any place you reference FDIC pass-through insurance eligibility, you must accompany that text with the approved disclosure language from Fifth Third Bank:

“Stripe Treasury Accounts are eligible for FDIC pass-through deposit insurance if they meet certain requirements. The accounts are eligible only to the extent passthrough insurance is permitted by the rules and regulations of the FDIC, and if the requirements for pass-through insurance are satisfied. The FDIC insurance applies up to 250,000 USD per depositor, per financial institution, for deposits held in the same ownership capacity.”

Viewing multiple balances

If you plan to allow connected accounts to store multiple balances, you must display balances separately within any dashboard user interface or servicing communications disclosing balances.

Feature availability on Fifth Third Bank

The following Treasury features are available when integrating with Fifth Third Bank.

We will release the following features for Fifth Third Bank next:

• [December] Remote deposit capture for check deposit
• Platform financial account at Fifth Third Bank
• Create a CreditReversal

If you request a financial account Feature that hasn’t been released for Fifth Third Bank, Stripe returns the following error: “You cannot request {feature} on a financial account with bank fifth_third”.

Get started with Treasury

You can use the existing Treasury documentation to guide your integration. You can use the same APIs with your Fifth Third financial account. Below is a list of expected differences with Fifth Third Bank.

1. You receive a platform financial account at Fifth Third Bank.

2. Outbound transfers sent using wire or ACH from a Fifth Third financial account have later cutoff times than today’s transfers sent with Evolve.

1. Stripe Payouts sent from the payments balance will arrive into a Fifth Third financial account faster than today’s payouts into an external bank account or an Evolve financial account.

There might be additional near-term differences while we build Fifth Third Bank to parity with Evolve. For example.

1. Received debits: Until the end of January 2025, you can only receive debits up to 500,000 USD per transaction. If an external party originates a debit for an amount exceeding 500,000 USD, Stripe originates a return with the R29 ACH return code. You won’t see any impact to your balance, and the received debit won’t appear in your transaction list. When we remove this limit, we’ll notify all platforms that have gone live with Fifth Third.
2. DebitReversals and CreditReversals: You must create a DebitReversal within 24 hours; we’ll extend this window in the coming months.
