Invoice payments are the place where a flat-rate card setup tends to cost the most, because of the prices the study quotes: Square charges a higher rate for invoices than for in-person payments, and Stripe adds an Invoicing fee on top of its card price. A QuickBooks Payments alternative with lower invoice fees usually has three parts: card pricing that shows the real costs, ACH bank payments as a second option, and a connection that keeps QuickBooks and your payments in step so you do not retype anything. This guide explains each part, lists the fee lines to look for on QuickBooks Payments or any provider, and shows what our 2026 pricing study found for invoices, with its limits.
The short answer
- Invoices are where the gap is widest. In NPS’s 2026 pricing study, a model, invoice sellers paid 19% to 31% less on interchange pass-through than on flat rate.
- Card pricing is only one lever. ACH bank payments and extra card data on business sales can lower the bill further.
- Check the lines that are not the rate. Instant deposits, invoice-specific rates, keyed rates, recurring billing and monthly fees can each add up.
- Keep QuickBooks in sync. A cheaper rate is not a saving if someone has to enter every payment by hand.
- Read the provider’s own current pricing page. We do not quote QuickBooks Payments prices on this page, because they change.

Why invoice payments cost more than counter payments
A card tapped at a counter is a different kind of transaction from a card entered on a payment page after an invoice arrives in an email. In the published pricing that NPS’s study collected, Square charges a higher rate for invoices than for in-person payments, and Stripe adds a separate Invoicing charge on top.
NPS’s 2026 pricing study quotes this pattern from published pricing, accessed in October 2026. Stripe’s own pricing page, read on November 13, 2026, lists an Invoicing fee of 0.4% on each paid invoice, on top of its 2.9% plus 30 cents card rate, and charges 0.5% more for manually entered cards. Square charges 3.3% plus 30 cents for invoices, against 2.6% plus 15 cents for in-person payments and 3.5% plus 15 cents for keyed or card-on-file payments. The study did not model QuickBooks Payments, and we are not stating its rates here. The numbers above show the pattern, not what you pay.
That pattern is why the question “how can I lower my invoice fees?” has a different answer from “how can I lower my store fees?” Look at your invoices separately from your in-person sales.
Where invoice costs hide
When you add up what an invoice really costs you, look in five places.
- The card rate for invoices. It may differ from the rate for in-person payments, and from the rate for cards you type in yourself.
- ACH fees. A bank-to-bank payment has its own price, often a flat or capped amount rather than a percentage.
- Speed charges. Fees for getting your money sooner than the standard schedule.
- Recurring and partial payments. Whether deposits, installments and repeating invoices cost extra.
- Software and seats. A monthly fee, extra fees per user, and the cost of any tool that connects payments to your accounting.
NPS’s page on how much you are really paying Stripe, Square, PayPal or QuickBooks describes how we work out the true total from about 90 days of dashboard data. You can do a first pass yourself with the steps below.
The fee lines to look for on QuickBooks Payments, or any provider
Open the provider’s current pricing page and your last few payout reports, and write down each line.
- Card rate for invoices paid online. The percentage and any fixed amount.
- Card rate for cards you key in. This applies when you type a customer’s card number from a phone call.
- Card rate for swiped or tapped cards. It matters only if you also take payments in person.
- ACH rate. Per transaction, as a percentage, with or without a cap, and the failed-payment charge.
- Speed fees. The cost of faster deposits.
- Monthly and per-user fees. What is included and what is extra.
- Volume discounts. The monthly volume at which the rate changes, and how you qualify.
- Dispute fees. What a chargeback costs, and whether it is returned if you win.
- Payout schedule and holds. How many days until deposit, and when funds can be held.
- Tie to your accounting software. Whether you can use a different processor and still keep the two-way sync with QuickBooks.
Before You Switch
Questions to ask any payment provider
- Ask for the card rate for invoices paid online, including any percentage and fixed amount
- Ask for the ACH rate: per transaction, percentage, cap, and failed-payment charge
- Ask whether the QuickBooks sync is two-way and covers invoices, customers, items and payments
- Ask whether Level 2 and Level 3 line-item data is passed automatically and how to confirm payments qualified
- Ask what happens to saved payment methods and what customers must re-enter
- Ask about speed fees, monthly fees, per-user fees and volume discounts
The last line is the key to an alternative. NPS built a QuickBooks Payments cost calculator where you can enter your own numbers.
What our 2026 pricing study found for invoices
NPS published a pricing study in 2026 that compares flat-rate pricing with interchange pass-through pricing. Two cautions come first. It is a model built on published rate schedules, not a survey of real businesses, and it was written by a processor that sells pass-through pricing.
Within the model, businesses selling by invoice or online paid 19% to 31% less in processing costs on pass-through than on flat rate, across average tickets from $15 to $2,500. For one example, a business collecting $50,000 a month through invoices at a $150 average ticket kept about $6,100 a year by moving from flat rate to pass-through. That is the model’s output with its stated inputs, not a promise, and the study says your statement determines your actual cost. Its invoice flat-rate benchmark was 3.3% plus 30 cents.
The study explains why invoices showed the biggest gap. Many small businesses pay invoices with a debit card. Federal rules cap the fee on debit cards from large banks at 0.05% of the sale plus 21 cents, with a 1 cent fraud adjustment, while flat-rate pricing charges the same percentage on a debit card as on a premium rewards card. Debit cards from smaller banks are exempt from the cap and cost more, and the model assumed 35% of debit volume came from those exempt cards. It assumed that debit makes up 25% of card payments at a $150 ticket and 22% at $300.
The study also says plainly that business and commercial cards carry higher interchange, which narrows the gap, and that extra data on those payments can lower it again. The model included business cards in its invoice credit assumption, set at 2.30% plus 10 cents blended. So if most of your customers pay with business credit cards, expect a smaller gap than if they pay with debit.
Put ACH next to cards
ACH is a bank-to-bank payment. NPS’s guidance is that ACH transfers typically have much lower flat fees than percentage-based card processing, and that it is often harder for a customer to reverse than a card. That makes it attractive for large and recurring invoices. The tradeoffs are that it takes longer to settle than a card and that a payment can fail if the account has too little money in it.
A common approach is to make ACH the default on the invoice and keep cards as an option for customers who want them. Whatever you choose, ask each provider how ACH is priced, how long it takes, and what a failed payment costs. NPS explains how this works in the ACH optimization guide.
Extra data on business cards: Level 2 and Level 3
If you sell to other businesses, some of your customers pay with corporate or purchasing cards. Sending extra details with those payments, such as tax and line-item data, can qualify them for lower interchange. These details are called Level 2 and Level 3 data. NPS’s pricing models guide describes them as reduced interchange rates, up to 1% less, for business-to-business and business-to-government merchants who provide the enhanced data.
This only helps if your invoicing system actually sends the data. Ask any provider whether it passes line-item data automatically and how you can check that your payments qualified. Ask your provider what data the card networks require on each transaction, because generic or repeated placeholder values may not qualify. We cover the details in Level 2 and Level 3 processing.
Keeping QuickBooks in sync
A cheaper rate does not help if your bookkeeper retypes every payment. Look at how a payment tool connects to QuickBooks Online before you compare prices. The words “integration” and “sync” cover a wide range, so ask these questions.
- Is the sync one-way or two-way? Can you create an invoice in either place, and does it appear in the other?
- Do customer records and items stay matched, or only the payment?
- When a customer pays, does the invoice close in QuickBooks automatically?
- How are fees and deposits recorded, so that your bank deposit matches your books?
- Are partial payments, deposits, credits and refunds handled?
- Do you pay extra per user?
NPS describes its Smart Invoicing (the NPSONE and ClickBillR platform) as a two-way sync with QuickBooks Online that covers invoices, customers, items and payments. It says the platform supports cards and ACH, payment links with your own branding, a customer portal, automated follow-ups, Level 2 and Level 3 data and unlimited user seats. We do not state that fee here. Read the details in our Smart Invoicing and QuickBooks hub and the QuickBooks payment integration guide, and ask for a demo with your own invoice.
How to compare using your own invoices
Here is a method that works with any provider.
- Export 12 months, or at least 90 days, of paid invoices and the fees that were taken from each.
- Split them by payment method: card, ACH, check, other.
- For card payments, split again by how the payment was taken: online invoice, keyed in, in person.
- Add up total card fees and divide by total card sales to get the effective rate. NPS’s guide to reading your merchant statement shows how.
- Give each provider the same set of transactions and ask them to price all of them, not an average.
Here is a hypothetical to show the arithmetic. Say you collect $40,000 a month by invoice and pay $1,320 in fees. Your effective rate is 3.3%. A quote that comes to $1,120 on the same invoices is $200 a month lower, or $2,400 a year. This is made-up math to show the method, not a promise. Your payment mix decides the real number.

Switching without disturbing your receivables
- Handle open invoices first. Decide whether open invoices stay on the old system until paid, or whether new links are sent. Do not leave customers with a dead link.
- Ask what happens to saved payment methods. Ask each provider whether cards or bank accounts already on file can move, and what customers must re-enter.
- Move recurring schedules carefully. List every repeating invoice, its date and its amount, and compare them after the move.
- Test with one real invoice. Pay it, check the QuickBooks entry and check the deposit.
- Tell your customers. A short note saying the payment page may look different avoids confused calls.
- Keep the old setup for a short overlap until the new one has paid out to your bank.
When staying put is the better answer
Staying may be right if your volume is low, if the savings are only a few dollars a month, or if you value having payments and accounting from one company above everything else. If most of your customers pay by business credit card and you cannot send line-item data, the gap will be smaller. We would rather say that than sell you a move that does not pay.

Who wrote this, and where NPS fits
Nationwide Payment Systems (NPS) publishes this guide. We are a payments company, in business since 2001, and we sell merchant accounts and the Smart Invoicing platform, so we are not neutral. We offer interchange-plus (cost-plus) and simplified pricing, and we do not publish one universal rate. You can browse our payments guides, or contact our team for a second opinion on a quote or a sample comparison on your own invoices.
We are not the right fit for everyone. If your payments are small and occasional, a bundled tool inside your accounting software may be all you need. We do not quote competitors’ current prices, because those change. Read each provider’s own pricing page.
Bottom line
Lower invoice fees come from three things: card pricing that shows the real costs, ACH as a second option, and a clean two-way connection to QuickBooks so no one retypes payments. In NPS’s 2026 pricing study, a model, invoices showed the widest gap between flat rate and pass-through, but business cards narrow that gap and your own mix decides your result. Read QuickBooks Payments’ own current pricing page, export your invoices, and compare line by line. If you want a second opinion, contact our team, and if staying put is the better answer for you, we will say so.
Frequently asked questions
Is there a QuickBooks Payments alternative with lower invoice fees?
Often, but it depends on your payment mix. Check the card rate for invoices, ACH pricing, speed fees and monthly fees, and ask for a quote on the same invoices you actually collected. In NPS’s 2026 pricing study, a model, invoice sellers paid 19% to 31% less on pass-through than on flat rate.
Can I keep QuickBooks if I change payment providers?
It depends on the provider. Ask whether the connection is two-way, whether invoices, customers and items stay matched, and how deposits and fees are recorded. NPS describes a two-way sync with QuickBooks Online in its Smart Invoicing platform.
Is ACH cheaper than cards for invoices?
NPS guidance says ACH transfers typically carry much lower flat fees than percentage-based card processing. It settles more slowly and can fail if the account lacks funds, so ask each provider about pricing, timing and failed-payment charges.
What are Level 2 and Level 3 data?
They are extra transaction details, such as tax and line items, that can qualify business, purchasing and government card payments for lower interchange. They help only if your invoicing system sends accurate data on each payment.
Do business credit cards change the savings?
Yes. The NPS 2026 pricing study says business and commercial cards carry higher interchange, which narrows the gap between flat rate and pass-through. Debit cards from large banks, which are capped, widen it.
How do I find out my real invoice cost?
Export 12 months or at least 90 days of paid invoices and fees, split them by payment method, and divide card fees by card sales to get your effective rate. NPS offers a free statement review, with no obligation to switch.
