Also called: E-Check, ECA, electronic check, electronic check acceptance
What an eCheck is
An eCheck is a payment authorized from a customer’s bank account and sent through the Automated Clearing House (ACH) network. The customer provides bank account details and permission for a one-time or recurring debit. The payment draws on available bank funds, not a credit line.
An eCheck is one kind of ACH payment. Direct deposit and other bank transfers also use ACH, but they are not all eChecks. The term ECA, or Electronic Check Acceptance, can also describe a service that converts a paper check into an electronic transaction. Confirm which service a provider means before comparing prices.
An eCheck can lower payment costs, but a returned debit still leaves you chasing the money.
How an eCheck moves
You collect the customer’s authorization and bank details, then submit the debit through your payment provider. ACH sends the payment instruction between financial institutions in batches. ACH does not process on weekends or bank holidays, so a payment submitted late in the week does not move like an instant card authorization.
The customer’s payment processing and the money arriving in your business account are separate steps. Your funding schedule is set during underwriting. Build that timing into cash-flow planning, especially when you use eChecks for payroll, large invoices or recurring bills.
How a flat fee changes by payment size
| $20 payment, $0.50 fee | 2.5% of sale (illustrative) |
|---|---|
| $500 payment, $0.50 fee | 0.1% of sale (illustrative) |
The fee and payment amounts are illustrative. Your provider sets your actual eCheck pricing.
What eChecks mean for your costs
There is no single standard eCheck fee. Providers set their own pricing, which can include a per-payment charge, a percentage, or fees for returned payments and additional services. Compare the full charge, not just a quoted rate, and check whether recurring payments or bank-account verification add separate costs.
A flat fee weighs more heavily on a small payment than a large one. For example, a $0.50 fee on a $20 payment equals 2.5% of the sale, while the same fee on a $500 payment equals 0.1% (illustrative). Compare eCheck pricing with your card costs using your actual payment sizes and return history.
Returns and payment risk
An eCheck can be returned for insufficient funds, incorrect account details or an unauthorized debit. As of 2026, most ACH returns must come back within two banking days. Consumer unauthorized-debit returns can come back up to 60 calendar days after settlement. A return can leave you without the sale proceeds and add a provider fee.
Keep a record of the customer’s authorization, the amount and any recurring schedule. Review returned-payment notices promptly, and reconcile the original debit against your bank deposits so a returned payment does not remain recorded as collected revenue.
What you can actually change
- Compare full pricing. Find the eCheck transaction charge, returned-payment fee and any monthly or verification fees. Calculate the cost using your average payment size.
- Save authorization records. Keep the customer’s permission, payment amount and recurring schedule together. This helps you investigate an unauthorized-debit claim or a disputed recurring charge.
- Reconcile returns. Match ACH return notices to your sales and bank deposits. Remove returned payments from collected revenue and follow up before relying on those funds.
Frequently asked questions
Is an eCheck the same as ACH?
No. An eCheck is one type of ACH payment, usually a debit authorized from a customer’s bank account. ACH also carries other payment types, including direct deposit, so not every ACH transaction is an eCheck.
How long does an eCheck take to reach my account?
ACH processing happens in banking days, not weekends or bank holidays. The date your business receives the funds depends on the funding schedule established during underwriting, so use that schedule rather than assuming the debit date is the deposit date.
How much does it cost to accept an eCheck?
There is no universal eCheck rate. Providers set their pricing, and fees can include a transaction charge or a fee for a returned payment. Compare every eCheck charge with your actual payment sizes and card costs.
Can a customer reverse an eCheck?
An ACH debit can be returned, including when a consumer reports an unauthorized debit. As of 2026, consumer unauthorized-debit returns can come back up to 60 calendar days after settlement. Keep authorization records and monitor return notices.
