Payment processing fees are the most negotiable cost most businesses never negotiate. They get skimmed off every transaction before the money lands in your account, and at scale they add up to a number that exceeds what most companies spend on software, rent, or customer support. The playbook for reducing them has barely changed in two decades.
This guide covers seven practical ways to evaluate payment costs. Compare each option against your transaction mix, customer preferences, and integration requirements.
What Payment Processing Fees Actually Cost You
Most US businesses pay one of a handful of headline rates:
- Stripe: 2.9% + $0.30 per online card transaction
- Square: 2.6% + $0.10 in person, 2.9% + $0.30 online
- PayPal: 3.49% + $0.49 standard checkout
- Adyen: interchange++ pricing, typically landing in the 2 to 3% band after card scheme and acquirer markups
- Modern crypto and stablecoin processors: generally 1 to 2%
At $1,000,000 in monthly volume, that's $29,000 to $35,000 per month going to card processors before you account for chargebacks, FX, or holds. For a business with thin margins, that's the difference between profitable and not.
The fee itself is not one number. It is a stack of three components:
- Interchange: the fee paid to the bank that issued the card. The largest component, set by Visa and Mastercard, non-negotiable.
- Scheme fees: charged by the card networks for using their rails.
- Processor markup: what your processor (Stripe, Square, Adyen, PayPal) adds on top.
You cannot reduce interchange or scheme fees. You can only reduce the processor markup, change which interchange tier your transactions land in, or switch to rails that do not use this stack at all.
Seven Strategies to Reduce Your Payment Processing Fees
1. Negotiate with your current processor
If you process more than $50,000 per month, your processor will negotiate. Most merchants never ask. Send your processor a request for a rate review, attach a summary of competing offers, and ask specifically for a reduction in the processor markup (not interchange, which is fixed). Realistic outcomes range from 5 to 25 basis points off, depending on volume and risk profile. For a $1M per month business, 15 bps is $1,500 per month, or $18,000 per year.
The catch: rates only go down when you ask. A processor that will not move on price at $1M per month is signaling that you are paying for something else, usually risk underwriting or premium service.
2. Switch from flat-rate to interchange-plus pricing
Flat-rate pricing (Stripe's 2.9% + $0.30, Square's 2.6% + $0.10) is simple but hides the markup. Interchange-plus pricing breaks it apart: you pay the actual interchange that day, plus a clearly stated markup (for example, 0.3% + $0.10).
For businesses with a card mix weighted toward debit, regulated cards, or lower-interchange categories, interchange-plus typically saves 30 to 80 basis points. For businesses with rewards-card-heavy customers, it can be more expensive. Run your last three months of transactions through an interchange calculator before switching.
3. Steer customers to lower-cost payment methods
ACH and bank transfers cost a fraction of card processing, often $0.25 to $1.00 per transaction with no percentage component. For high-value B2B transactions ($500 or more), steering customers to ACH instead of card can save 90% or more of the fee.
Steering is mostly about defaults: which option appears first at checkout, whether you require ACH above a threshold, whether you offer a small incentive for non-card payment. SaaS businesses with annual contracts and B2B suppliers benefit the most. Consumer e-commerce checkouts struggle to steer effectively because card defaults are entrenched.
4. Surcharge or offer a cash discount
In most US states you can legally pass card processing fees onto the customer by adding a surcharge, or offering a discount for non-card payment. Rules vary by state and by card network (Visa and Mastercard have specific disclosure and cap requirements).
When done correctly, surcharging removes the fee entirely from your P&L. It also reduces conversion: some percentage of customers will abandon at checkout. Most businesses that surcharge net out ahead, but the gain is split between fee savings and conversion loss. Best for repeat-buyer businesses where the relationship absorbs the friction.
5. Reduce chargebacks
Every chargeback costs $15 to $25 in fees on top of the lost transaction, and high chargeback ratios trigger penalty pricing or termination from your processor. For a business doing 5,000 transactions a month with a 1% chargeback rate, that's $750 to $1,250 per month in chargeback fees alone, plus the lost revenue from those orders.
Common prevention strategies: clear billing descriptors so customers recognize the charge, proactive shipping confirmations, fraud filters like Stripe Radar or Signifyd, and 3D Secure on high-risk transactions. Most businesses can cut chargeback rate by 50 to 70% with a focused effort.
6. Accept stablecoins and bitcoin
Stablecoin and bitcoin payments settle without the card scheme stack. There is no interchange, no scheme fee, no chargeback. The infrastructure looks different (a payment processor like Amboss instead of a card acquirer), but the effect on cost is direct.
For global businesses, stablecoin payments also remove FX fees and the days-long settlement delay that comes with cross-border card processing. Settlement is in seconds. The catch is customer demand: you need a customer base willing to pay this way. For exchanges, wallets, marketplaces, and global SaaS, the share is growing.
7. Compare a proposal built around your business
Ask providers to quote against the same payment volume, transaction sizes, currencies, and settlement requirements. Include integration and operating costs in the comparison.
Amboss Payments provides Bitcoin and stablecoin payment acceptance through an API. Pricing is agreed individually around your business requirements. You do not need to deploy capital into a yield product to accept payments.
To evaluate costs, talk to our team and compare your proposal with the total fees on your current processing statements. Any savings depend on the agreed terms and the volume customers choose to pay through each method.

Frequently Asked Questions
What is the average payment processing fee?
For US businesses accepting cards online, the average effective rate lands between 2.5% and 3.5% of transaction volume once interchange, scheme fees, and processor markup are combined. Flat-rate processors like Stripe, Square, and PayPal typically sit at the high end. Interchange-plus pricing can land lower for businesses with the right card mix. Crypto and stablecoin processors generally run between 1% and 2%.
Can you negotiate credit card processing fees?
Yes, but the negotiation only applies to the processor markup, not the interchange or scheme fees set by Visa and Mastercard. Most processors will negotiate with merchants doing $50,000 per month or more in volume. Realistic savings range from 5 to 25 basis points off the markup. Bring competing offers and ask specifically for a rate review.
What is interchange-plus pricing?
Interchange-plus is a pricing model where the processor passes the actual interchange and scheme fees through at cost, then adds a clearly stated markup on top (for example, 0.3% + $0.10 per transaction). It contrasts with flat-rate pricing, where the processor bundles everything into one number (for example, 2.9% + $0.30). For businesses with a card mix tilted toward lower-cost interchange categories, interchange-plus typically saves money. For businesses with rewards-card-heavy customers, it can be more expensive.
How much can you save by switching processors?
For most businesses doing $250,000 per month or more in card volume, switching from a flat-rate processor to interchange-plus saves 30 to 80 basis points, or roughly $750 to $2,000 per month at that volume. Switching to stablecoin or bitcoin rails (where customer demand exists) typically saves 100 to 200 basis points. The largest savings come from changing the rail entirely, not from changing the processor on the same rail.
Can you reduce payment processing fees below the sticker rate?
Evaluate your total cost, including processing, currency conversion, settlement, refunds, and operating expenses. Amboss provides tailored commercial terms; compare your proposal against your current payment mix rather than assuming a universal rate or savings percentage.
