What it means
The mechanics are simple from the payer's side. They supply their bank account number and routing number, authorise the merchant to collect a stated amount, and the merchant's bank sends a debit instruction through the automated clearing network to the payer's bank.
No cheque is written, signed, posted or deposited, but the funds move between the same two accounts. The reason businesses care is cost.
Card acceptance is priced as a percentage of the transaction plus a small fixed fee, so a large payment costs a lot to accept, while an electronic check is usually priced as a flat fee of a few tens of cents regardless of size. For any business collecting high-value recurring payments, the difference is substantial.
The trade-off is speed and finality. Card authorisations are close to instant while electronic checks settle over one to three business days, and unlike a card authorisation there is no upfront guarantee that the funds exist.
Payments can be returned for insufficient funds or a closed account days after they appeared to succeed. Risk management therefore looks different.
Merchants use account validation services, hold higher-risk orders until settlement clears, and monitor their return rate closely because clearing networks impose thresholds above which a merchant can lose access. Returns also carry a fee, which has to be built into the cost comparison.
The common variants are worth distinguishing. A converted cheque is a paper cheque scanned and processed electronically, a web-initiated debit is one authorised online, and a telephone-initiated debit is authorised verbally, and each carries slightly different authorisation and record-keeping obligations.
In everyday business language all three tend to be called an electronic check.
In practice
Real-world examples.
Example
A commercial landlord collects monthly rents averaging $4,500 from 200 tenants. Moving from card payments to electronic checks removes well over $200,000 a year in processing fees, and the landlord passes part of the saving back as a small discount to encourage the switch.
Example
A software vendor bills annual subscriptions of $12,000. Card acceptance would cost roughly $300 per renewal, so the vendor offers electronic check as the default on invoices above $2,000 and reserves cards for smaller monthly plans.
Example
A veterinary equipment distributor experiences a spike in returned payments after a customer's account is closed without notice. It introduces bank account validation at order entry and its return rate falls back below 0.5% within a quarter.
Formula
Calculation
Net Saving = (Card Cost per Transaction - Electronic Check Cost per Transaction) x Volume - Return Costs
A wholesaler collects 6,000 payments a month, averaging $850 each. Its card processor charges 2.5% plus $0.30, so a typical transaction costs ($850 x 0.025) + $0.30 = $21.25 + $0.30 = $21.55, and the monthly card cost is 6,000 x $21.55 = $129,300.
Its bank prices electronic checks at a flat $0.45 each, so the same volume costs 6,000 x $0.45 = $2,700 a month. The gross saving is $129,300 - $2,700 = $126,600.
Returns must be netted off. At a return rate of 0.8%, 6,000 x 0.008 = 48 payments come back each month at a $5 return fee, costing 48 x $5 = $240. The net monthly saving is $126,600 - $240 = $126,360, or $1,516,320 over a year, which is why high-ticket business-to-business sellers push customers away from cards.Case study
Seen in the real world.
Cobalt Ridge Wholesale is an invented distributor used here as an illustrative example. It processed 6,000 customer payments a month averaging $850, almost all on commercial cards, at a blended cost of 2.5% plus $0.30 per transaction, which came to $129,300 a month.
The finance director calculated that the same volume through electronic checks at $0.45 each would cost $2,700, a gross saving of $126,600 a month. Even after allowing for a 0.8% return rate at a $5 fee per return, which added $240, the net saving was $126,360 a month or $1,516,320 a year.
The change was not free of friction. About a fifth of customers preferred cards for the rebate they earned, so Cobalt Ridge offered a 0.5% early settlement discount on electronic check payments, which cost less than the card fees it replaced and converted most of the holdouts. It also added account validation at order entry after two returns from closed accounts, and now reviews its return rate monthly alongside its days sales outstanding.
Watch out
Common mistakes.
- Assuming an electronic check clears instantly like a card authorisation. Settlement usually takes one to three business days and a payment can still be returned after it appears to have succeeded.
- Comparing costs on the fee alone. Return fees, validation service charges and the working capital cost of slower settlement all belong in the comparison.
- Ignoring the return rate until the bank raises it. Clearing networks set thresholds and a merchant that breaches them can have its facility withdrawn at short notice.
Questions
People also ask.
Is an electronic check the same as a wire transfer?
No, a wire is a same-day push payment initiated by the payer and is generally irreversible, whereas an electronic check is a lower-cost pull payment that can be returned.
Do I need written authorisation from the customer?
You need a recorded authorisation appropriate to the channel, which may be an online tick box, a signed mandate or a recorded call, and it must be retained for the period the network rules require.
Why do large business-to-business sellers prefer them?
Because the flat per-item price means the cost of accepting a $50,000 payment is the same as accepting a $500 one, which is not true of card acceptance.
