The Cheapest Way to Accept Card Payments (2026)

Our verdict

Bank transfer is normally cheaper than accepting a card because it can avoid percentage-based processing fees. When a customer needs to pay by card, compare the effective rate for your typical transaction—not just the advertised headline rate—and treat InvoiceSonic as the invoice layer rather than a card processor.

When you are ready to create the document, use the free invoice generator; for saved clients and repeat workflows, explore the InvoiceSonic invoicing app.

How we compared the options

This comparison considers total processing cost, settlement method, regional availability, client friction and how each payment rail connects to a proper invoice. Percentage fees are separated from the cost of creating the invoice itself.

Every card payment you accept takes a slice off the top. On a $50,000 year that is somewhere between $750 and $1,750 gone — for the privilege of being paid for work you already did. This is a straight comparison of what each option charges, and an honest answer to the question underneath it: whether you need to accept cards at all.

What each option actually costs

Rates below are the standard published rates for in-country online payments. Card-not-present, international cards and currency conversion all cost more.

1. Bank transfer — genuinely free, everywhere

The default for business-to-business payments in every market we serve, and it costs nothing at either end. The real cost is friction: account numbers get mistyped and "I'll do it tonight" turns into three weeks. Both are fixable by putting the details somewhere the client cannot miss them. The free invoice generator lays out BSB and account number, sort code, routing number or IBAN in the right format for your country.

2. PayID — the Australian answer

Instant Osko transfer to a phone number, email address or ABN, with the money in your account in about a minute and no fee at either end. If you invoice Australian clients and are not offering PayID, you are paying a processor for something the banks do free. Details go on the invoice the same way — see the PayID invoice template.

3. Zelle — the US equivalent

Bank-to-bank, no fee, usually minutes. The catch is that Zelle has no invoicing layer at all, so the request arrives with no record of what it was for. Send a proper invoice alongside it: how to use Zelle for business covers the limits and the bookkeeping problem.

4. Venmo business — cheapest of the card-style rails

At 1.9% + $0.10, Venmo undercuts Square, Stripe and PayPal meaningfully, and for a certain kind of client it is the only thing they will reliably use. Worth it when the alternative is not being paid. See Venmo for business.

5. Square and Stripe — pay for the convenience

Both sit around 2.9% + $0.30. You are buying instant acceptance, a hosted checkout and dispute handling. That is a real product, and for retail or high-volume card work it earns its keep. For a tradie sending eight invoices a month it is an expensive way to avoid asking for a bank transfer. Stripe's fees explained in full.

6. PayPal invoicing — the most expensive of the mainstream options

Up to 3.49% plus a fixed fee, and the highest of the common rails. It is also the most widely recognised, which is why people keep using it. If you invoice through PayPal out of habit rather than client demand, that habit costs real money.

So what is actually cheapest?

Not accepting cards. For most sole traders, contractors and freelancers, the cheapest setup is: bank transfer or PayID/Zelle as the default on every invoice, with one card-style rail available for the clients who insist. That keeps the processor out of 90% of your revenue instead of all of it.

Work out your own number with the payment fee calculator — put in what you invoice a month and it shows what each rail costs you a year.

Making it easy for the client

The reason people default to cards is that bank transfer feels like homework. It stops feeling that way when the invoice does the work: correct account fields for the country, the reference pre-filled, and a clear "how to pay" block. That is what InvoiceSonic does — we make invoicing software and we do not take a percentage of your payments, because we are not a payment processor. Whatever you use, put the free rails on the invoice first.

Compare the cost on a real sale

Advertised percentages do not show the whole cost when a provider also charges a fixed fee, monthly subscription, hardware cost, cross-border markup or chargeback fee. Test providers using the transaction sizes and monthly volume your business actually processes. The payment fee calculator converts the percentage and fixed component into a comparable effective cost.

Also compare settlement speed, refund handling and reconciliation reports. A slightly cheaper rate can cost more operationally if payouts combine transactions without clear references or if customers cannot use their preferred method.

Recheck the decision as volume changes

The cheapest provider at low volume may not remain cheapest after transaction count, average invoice size or international sales change. Compare a representative month at least periodically and include refunds, disputes and hardware. Keep the payment option that customers actually complete, not merely the one with the lowest headline rate.

Negotiate from evidence

Keep several months of processed volume, average transaction value, refund rate and card mix. Providers can evaluate real usage more accurately than an optimistic forecast. Ask which charges are negotiable and whether a lower rate introduces a contract, monthly minimum or different settlement terms.

Document the comparison and repeat it after a material change. The goal is not switching constantly; it is knowing that the current method remains economical for the invoices the business actually sends.
