Square Invoice Fees: Why 3.3% + 30c Costs More Than Tap

As read on Square’s fees page on November 13, 2026, Square lists 2.6% plus 15 cents for a card taken in person and 3.3% plus 30 cents for online sales and invoices. On a $150 sale that is $4.05 in person and $5.25 as an invoice, so the same sale costs $1.20 more once it is billed by invoice. This guide lays Square’s four listed rates side by side, prices four sale sizes each way, explains why an invoice is priced like an online sale, and shows where pass-through pricing changes the picture.

The short answer

An invoice is priced like an online sale, not like a tap. As read on Square’s fees page on November 13, 2026, online sales and invoices share one line: 3.3% plus 30 cents. Check Square’s own page for today’s price.
Our arithmetic: the invoice price is 0.7% of the sale plus 15 cents higher than the in-person price. That is $0.50 on $50, $1.20 on $150, $3.65 on $500 and $17.65 on $2,500.
The 30 cents hurts small invoices most. The all-in rate is 3.90% on a $50 invoice and 3.31% on $2,500.
Pass-through can change the picture. NPS’s 2026 pricing study is a model, built by a processor that sells pass-through pricing, so treat it as a reason to get a quote, not proof of your savings.
Take the in-person rate when the customer is with you. Send the invoice when they are not.

Square’s four listed rates, side by side

Square’s fees page, as read on November 13, 2026, lists four card prices that matter to a small business. Each is a percentage of the sale plus a fixed amount on every payment.

Tap, dip or swipe: 2.6% plus 15 cents.
Online sales or invoices: 3.3% plus 30 cents.
Online API: 2.9% plus 30 cents.
Manual entry or card on file: 3.5% plus 15 cents.

In-person vs invoice

Same sale, different fee

Listed rate: Card in person (tap, dip or swipe)2.6% + 15¢; Invoice or online sale3.3% + 30¢
Fee on $150 sale: Card in person (tap, dip or swipe)$4.05 (2.70%); Invoice or online sale$5.25 (3.50%)
Fee on $500 sale: Card in person (tap, dip or swipe)$13.15 (2.63%); Invoice or online sale$16.80 (3.36%)

Take the in-person rate when the customer is with you. Send the invoice when they are not.

Our arithmetic from Square’s listed rates as read on November 13, 2026; not a promise about your account.

Square changes its prices from time to time, and some accounts have custom terms. Open Square’s fees page and your own account’s fee settings before you rely on any number here. Every Square figure in this guide is the one we read on November 13, 2026.

Read the list the way a buyer would. The cheapest line is the one for a card in your hand. The most expensive percentage is the line for typing in a card number or charging a saved card. Invoices sit in the middle on percentage and at the top on the fixed part, since 30 cents is double the 15 cents charged in person.

What the same sale costs four ways (our arithmetic)

This is made-up math to show the method, not a promise about your account. We took Square’s listed rates as read on November 13, 2026, and worked out one sale at four sizes. We checked each result with a calculator script.

$50 sale: in person $1.45 (2.90%), online API $1.75 (3.50%), invoice $1.95 (3.90%), manual or card on file $1.90 (3.80%).
$150 sale: in person $4.05 (2.70%), online API $4.65 (3.10%), invoice $5.25 (3.50%), manual or card on file $5.40 (3.60%).
$500 sale: in person $13.15 (2.63%), online API $14.80 (2.96%), invoice $16.80 (3.36%), manual or card on file $17.65 (3.53%).
$2,500 sale: in person $65.15 (2.61%), online API $72.80 (2.91%), invoice $82.80 (3.31%), manual or card on file $87.65 (3.51%).

Fee by sale size

Invoice fees grow with the sale

Sale size	In-person fee	Invoice fee
$50	$1.45 (2.90%)	$1.95 (3.90%)
$150	$4.05 (2.70%)	$5.25 (3.50%)
$500	$13.15 (2.63%)	$16.80 (3.36%)
$2,500	$65.15 (2.61%)	$82.80 (3.31%)

Made-up math to show the method, not a promise about your account.

Three things stand out. First, the gap between an invoice and a card in hand grows with the sale, because the extra 0.7% is a percentage: it is $0.50 on $50 and $17.65 on $2,500. Second, the 30 cents matters most on small sales, which is why the invoice rate is 3.90% at $50 and falls toward 3.3% as the sale grows. Third, the online API price (2.9% plus 30 cents) is cheaper than the invoice price at every size above. Check with Square how the online API price applies to your account.

Why an invoice is priced like an online sale

Square’s fees page lists invoices on the same line as online sales. It is a flat-rate price, which means one headline price for the payment whichever card the customer uses. An invoice is a payment where the customer is not standing at your counter with a card. They open a link, type a card number into a form and pay. That is how an online sale works too, so Square gives it the online price.

The effect is plain: the same $150 job costs $4.05 when you tap a card and $5.25 when you send a bill. If a customer is at your shop, a tap or dip is the listed cheaper way to collect. If they are across town, the invoice is the convenient way, and the extra $1.20 is the price of that convenience.

The other listed prices give you the same lesson in a different shape. A manually entered card or a card on file is 3.5% plus 15 cents, which is $5.40 on $150, against $5.25 for an invoice. Typing a card number in costs about the same as, or a little more than, sending a bill, so there is no listed shortcut that makes a remote payment cheap.

What it adds up to over a year

One sale looks small. Over a year it does not. Here is the arithmetic for a service business, again made-up math to show the method.

100 invoices a month at $150 is $15,000 collected. At 3.3% plus 30 cents, the invoice fees are $525.00 a month, or $6,300.00 a year. The same 100 sales taken in person at 2.6% plus 15 cents would be $405.00 a month, or $4,860.00 a year. The difference is $120.00 a month, or $1,440.00 a year.
$50,000 a month at a $150 ticket is about 333 invoices a month. Square’s invoice price on that volume is about $1,750.00 a month, or $21,000.00 a year. In person, it would be about $1,350.00 a month. The difference is about $4,800.00 a year.

You will not collect every sale in person, and you should not try to. The point is to know what the convenience of billing costs you, so you can decide which jobs to bill and which to take on the spot.

Where pass-through pricing changes the picture

Square is a flat-rate processor. Interchange pass-through, also called interchange-plus, is a different model: you pay the real card-network cost of each payment plus one markup written in your agreement. NPS explains the models in its guide to where flat-rate fees actually go, and its main comparison guide covers the whole field.

The pricing study, “The Flat-Rate Tax” (2026 Edition), was written by Allen Kopelman, the CEO of NPS. It is a cost model built from published rate schedules, not a survey, and NPS sells pass-through, so we are not neutral. For businesses selling online or by invoice, the model finds pass-through costs 19% to 31% less than flat rate across average tickets from $15 to $2,500. Interchange varies by card type, business and commercial cards can cost more, and Level 2 and Level 3 data can lower them.

This is our arithmetic, applying the study’s range to Square’s 3.3% plus 30 cents invoice price. It is a picture of the model, not a quote and not a promise.

$50 invoice: Square lists $1.95. At 19% to 31% less, the model gives about $1.35 to $1.58.
$150 invoice: Square lists $5.25. At 19% to 31% less, the model gives about $3.62 to $4.25.
$500 invoice: Square lists $16.80. At 19% to 31% less, the model gives about $11.59 to $13.61.
$2,500 invoice: Square lists $82.80. At 19% to 31% less, the model gives about $57.13 to $67.07.

The study also gives one yearly example: $50,000 a month in invoices at a $150 average ticket keeps about $6,100 a year in the model. Your own number depends on your card mix, so the only figure that settles the question is the one on your own statement.

Debit is part of why. Interchange on debit cards from large banks is capped at 0.05% of the sale plus 21 cents, with a 1 cent fraud adjustment. A flat rate charges its full price on those cards anyway. The cap does not apply to debit cards from small banks, and NPS has a post on whether the debit cap applies to small-bank cards.

When Square’s flat rate can still be the right call

Do not leave a tool that works because a fee looks high on paper. The study itself says flat rate can still win in some cases:

Very small tickets taken in person, around $15 and under.
A brand-new business with very low volume.
A business that sends only a few invoices a month, where the yearly difference is small and switching costs time.

Switching deserves a look when your yearly invoice fees are a real number and a good share of your sales are billed rather than tapped.

How to work out your own invoice cost in ten minutes

Export a month of Square sales. Split them into in-person payments and invoices, and add up the dollars and the number of payments in each.
Find the fee total. Divide the fees by the dollars collected for each group. That is your effective rate.
Compare to the listed prices. If your invoice rate is near 3.5% at a $150 average, you are paying about what Square’s listed prices imply. If it is higher, look for manual-entry and card-on-file payments.
Multiply by twelve. The yearly figure is the one that changes decisions.
Get one written quote and compare line by line. Ask for the markup, the monthly fee, the gateway fee, the statement fee, any invoice fee and the contract terms.

Questions to ask any processor before you move

What is the markup over interchange, in writing, and is it fixed?
Is there any fee just for sending an invoice or a payment link?
What do keyed or card-on-file payments cost?
Are there monthly, gateway, statement or PCI fees?
Can I see a sample statement that shows each fee on its own line?

If an answer is “it depends,” ask on what. A clear answer lets you do the arithmetic above yourself.

Before you switch

Ask any processor these five questions

What is the markup over interchange, in writing, and is it fixed?
Is there any fee just for sending an invoice or a payment link?
What do keyed or card-on-file payments cost?
Are there monthly, gateway, statement or PCI fees?
Can I see a sample statement that shows each fee on its own line?

Frequently asked questions

What does Square charge for an invoice?

As read on Square’s fees page on November 13, 2026, online sales and invoices are listed at 3.3% plus 30 cents. In-person payments by tap, dip or swipe are listed at 2.6% plus 15 cents. Check Square’s own fees page for today’s prices.

How much more is an invoice than an in-person sale?

Our arithmetic from Square’s listed rates: the gap is 0.7% of the sale plus 15 cents. On $150 that is $1.20, on $500 it is $3.65, and on $2,500 it is $17.65. It is made-up math to show the method, not a promise about your account.

Can I pay the lower in-person rate on an invoice?

Not by the listed prices. Square’s fees page, as read on November 13, 2026, puts invoices on the same line as online sales. The 2.6% plus 15 cents rate is listed for tap, dip or swipe. If a customer is standing in front of you, taking the card in person is the listed cheaper route. Ask Square how your own account is charged.

Is a card on file or manually entered card cheaper than an invoice?

Per the fees page as read on November 13, 2026, manual entry or card on file is 3.5% plus 15 cents. Our arithmetic: that is $5.40 on $150 against $5.25 for an invoice, so it is a little more on larger sales and a little less on small ones. On $50 it is $1.90 against $1.95.

Can a pass-through processor beat Square’s invoice price?

Often, in our study’s model, which finds interchange pass-through costs 19% to 31% less than flat rate for online and invoice sales across $15 to $2,500 tickets. It is a model from a processor that sells pass-through pricing, so test it against your own statement.

What is the study’s one yearly example?

$50,000 a month in invoices at a $150 average ticket keeps about $6,100 a year in the model. Your result depends on your card mix and fees, so ask for a quote rather than relying on the example.
