FAQs

How do payment companies profit from float?

When customers hold balances in payment apps (PayPal, Cash App, Venmo) or when funds are in transit through a payment network, the company holds those funds in interest-bearing accounts. At scale — billions in aggregate customer balances — even short-duration interest at 4–5% generates hundreds of millions in annual revenue. This 'float income' is increasingly disclosed as a key revenue line in fintech financial statements.

What is check kiting and why is it illegal?

Check kiting is fraud that exploits check float by writing checks between accounts at different banks before funds clear, artificially inflating available balances. It exploits the delay between check deposit and the issuing bank's debit. With electronic check clearing drastically reducing float, kiting is less viable and increasingly detected by bank fraud systems.

How has Same-Day ACH affected float management?

Same-Day ACH (launched 2016) dramatically reduced both disbursement and collection float for ACH transactions from 1–2 business days to same-day settlement. For merchants, this means faster access to customer payments. For accounts payable, it means less opportunity to delay disbursements. Real-time payment networks (RTP, FedNow) have reduced float to seconds.

Float refers to the money that exists temporarily due to delays in processing payments — the period between when a payment is initiated (check written, ACH initiated, wire sent) and when the funds are actually moved from the payer's account or credited to the payee's account. Float creates a situation where the same money appears to exist in two places simultaneously.

There are two types from opposite perspectives: disbursement float (also called negative float or payment float) is the time after a business writes a check or initiates a payment but before it clears — during this window, the funds remain in the payer's account earning interest or covering other needs. Collection float (positive float) is the delay between when a payment is received (check deposited) and when funds become available for use.

Historically, check float was a major source of value for large companies. By timing payment issuance carefully and managing a portfolio of outstanding checks (a practice called 'playing the float'), treasury teams could keep millions in their accounts longer. The Check 21 Act (2004) and the subsequent rise of electronic payments dramatically reduced check float as check imaging and electronic clearing shortened clearing times from days to hours.

In fintech, float is a significant business model element. When a payment platform holds customer funds during transaction processing — even for seconds or hours across millions of transactions — the aggregate 'float' earns interest that can be material. PayPal historically held $15–25 billion in customer balances, generating substantial interest income. Square Cash App and other payment apps similarly benefit from float on stored balances.

For merchants, reducing collection float (getting paid faster) improves cash flow. Same-Day ACH, real-time payments (RTP network), and instant card settlement options have reduced collection float from days to hours for many payment types.
