Best Payment Processing and Financing for Auto Parts Sellers
Nine payment, financing and fraud options for parts sellers, judged on high-ticket orders, wrong-fit chargebacks and PCI.
A parts store takes payments that a T-shirt shop never sees: a $3,800 long travel kit, a set of 37 inch tires on new wheels, a crate engine shipped by freight. The payment setup has to take cards at a fair rate, let a buyer spread a big build over months, stop the stolen card before a turbo kit ships, and survive the chargeback that follows a part that did not fit.
This guide covers the payment, financing and fraud tools parts sellers ask us about most, who each one fits and where each one falls short. Our integration partners are listed first, and every one of them gets the same honest pros and cons as the option that is not a partner. Fees come from each provider’s own website, read on October 14, 2026. Where a provider does not publish pricing, we say so. Rates change, so confirm them before you sign.
How to choose payments for an auto parts store
Generic payment reviews compare rates and stop. Parts sellers should check six things.
- Published rates. A rate you can read lets you price a $2,000 order before it happens. Quoted pricing is not bad, but get it in writing.
- Financing for every credit profile. Big builds sell better with monthly payments. Prime lenders decline some buyers; a second provider can catch them.
- Fraud screening on high-value orders. Stolen cards go after expensive, easy-to-resell parts. You want scoring and a review queue, not only a yes or no from the bank.
- Chargeback cost and tools. Compare dispute fees and how evidence is submitted. In this industry many disputes start as a part that did not fit.
- PCI scope. Hosted, tokenized card fields keep card numbers off your server. That keeps your setup PCI-aligned and your yearly paperwork smaller.
- Wallets on mobile. Apple Pay and Google Pay remove typing from a phone checkout, where many parts shoppers start.
Nine payment, financing and fraud options for parts sellers
The first eight are Web Shop Manager integration partners, listed first and grouped by job: card processing, financing, wallets, then fraud. Signifyd, which is not a partner, comes last. Each partner links to its integration page on our site.
1. Stripe
Stripe processes cards, digital wallets and other payment methods through one account. Its US pricing page lists 2.9% + 30¢ per successful domestic card transaction, plus 1.5% for international cards and 1% when currency conversion is needed. A dispute costs $15, and responding to one costs another $15 that Stripe returns if you win. There are no setup or monthly fees. Radar, Stripe’s fraud screening, is listed from $0.05 per screened transaction or from $10 a month on a plan. Card fields are hosted and tokenized, so card numbers do not pass through your web server.
Who it fits: parts sellers who want cards, Apple Pay, Google Pay and fraud screening on one account, with rates they can read before they sign up.
Where it falls short: the flat rate applies to a $4,000 suspension kit the same way it applies to a $40 filter, so large tickets cost real money unless you negotiate. Like other payment aggregators, Stripe can review an account or hold funds when volume or ticket size jumps, which can catch a growing parts store during its busy season. See the Stripe integration with Web Shop Manager.
2. PayPal
PayPal lets shoppers pay with a PayPal account, cards, or Pay Later, and it can also process cards on your own checkout. Its US merchant fee page, last updated October 1, 2026, lists 3.49% + $0.49 for PayPal Checkout, 2.99% + $0.49 for standard card payments, 2.89% + $0.29 for advanced card payments and 4.99% + $0.49 for Pay Later. Chargebacks cost $20, disputes $15 (or $30 under its high volume dispute fee), and international transactions add 1.5%.
Who it fits: stores where first-time buyers hesitate to type a card number into a site they have never heard of. A PayPal button is familiar, and Pay Later gives a buyer a way to split a mid-size order.
Where it falls short: PayPal Checkout and Pay Later carry the highest published percentages on this list. Buyers can open a dispute in PayPal instead of asking you for a return, so a part that did not fit can reach you as a claim before it reaches you as an email. See the PayPal integration with Web Shop Manager.
3. Authorize.Net
Authorize.Net is a payment gateway owned by Visa. Its pricing page lists two plans at $25 a month: All-in-One at 2.9% + 30¢ per transaction, or Gateway Only at 10¢ per transaction plus a 10¢ daily batch fee for merchants who already have a merchant account. There is no setup fee, the Advanced Fraud Detection Suite is included in both plans, and card chargebacks are listed at $0 (eCheck chargebacks are $25).
Who it fits: parts businesses that already have a merchant account through their bank, wholesale sellers who take eChecks, and stores that want configurable fraud filters without a separate fraud bill.
Where it falls short: the $25 monthly fee is charged whether you process ten orders or ten thousand. On Gateway Only you are dealing with two companies, the gateway and your processor, and each has its own fees and statements. See the Authorize.Net integration with Web Shop Manager.
4. Affirm
Affirm offers buy now, pay later financing at checkout. Its site lists Pay in 4 at 0% APR and monthly installment plans with rates from 0% to 36% APR based on credit and subject to an eligibility check. Affirm says options depend on the purchase amount and may vary by merchant. Merchant fees are not published on its site; you get them in a quote.
Who it fits: high-ticket builds where the buyer has good credit and would rather pay for a lift kit, wheels and tires over a year than put it all on one card.
Where it falls short: approval depends on the shopper’s credit, so a share of applicants will be declined or offered a shorter plan. Because merchant pricing is quoted, you cannot compare its cost against card processing until you ask. See the Affirm integration with Web Shop Manager.
5. PayTomorrow
PayTomorrow is a financing platform used by automotive, wheel and tire sellers. It describes itself as a waterfall: one application is passed to several lenders, so prime, near-prime and nonprime shoppers can each get an offer. In July 2024 it added Katapult’s lease-to-own option to that waterfall. Rates and merchant fees are not published on its site.
Who it fits: wheel, tire and accessory sellers whose buyers include people a prime lender would decline. Pairing PayTomorrow with Affirm covers more of your buyers than either alone.
Where it falls short: lease-to-own costs the buyer more than the cash price, and buyers do not always read the terms. Make sure your product pages and order emails explain that the shopper is entering a lease or loan with a third party, not a store discount. See the PayTomorrow integration with Web Shop Manager.
6. Apple Pay
Apple Pay is a wallet, not a processor: Apple tells merchants to turn it on through their payment provider. Each payment is approved with Face ID, Touch ID or a passcode, and Apple says merchants do not receive the shopper’s actual card number. Your processor’s normal rate applies to Apple Pay orders.
Who it fits: any store with real mobile traffic. A shopper buying brake pads from a phone in the garage can pay without typing a card number or a shipping address.
Where it falls short: it only appears for shoppers on Apple devices and supported browsers, and it does nothing for financing or fraud review on its own. It also depends on your processor supporting it. See the Apple Pay integration with Web Shop Manager.
7. Google Pay
Google Pay works the same way on Android and Chrome. When a shopper picks a saved card, Google returns a payment token to your checkout and your processor charges it. Google publishes a list of supported processors and gateways. Your processor’s normal rate applies.
Who it fits: stores with a large share of Android shoppers.
Where it falls short: like Apple Pay, it is a faster way to pay through your existing processor, not a separate way to lower fees, finance an order or stop fraud. See the Google Pay integration with Web Shop Manager.
8. Kount
Kount, an Equifax company, screens orders for payment fraud and offers dispute and chargeback management that pulls card brand alerts into one dashboard. When we checked on October 14, 2026, kount.com redirected to Equifax’s identity and fraud pages. Pricing is not published.
Who it fits: parts sellers with enough high-value order volume that manual review no longer keeps up, and who want fraud scoring and chargeback alerts from one vendor.
Where it falls short: it is priced by quote and sold to businesses of some size, so a small store may get more from the fraud tools already included with Stripe or Authorize.Net. Rules need tuning: a strict setup will decline legitimate orders shipping to a shop or installer instead of the billing address. See the Kount integration with Web Shop Manager.
9. Signifyd
Signifyd is not a Web Shop Manager partner. It is a fraud and chargeback service that takes on the fraud risk itself: Signifyd says that if an order it approved turns out to be fraud, it covers the loss. It also lists chargeback recovery services. Pricing is not published on its home page.
Who it fits: sellers who want a third party to carry the fraud loss on approved high-value orders rather than tune rules themselves.
Where it falls short: there is no Web Shop Manager integration today, so ask how it would connect to your checkout before you sign. Read which dispute reasons that coverage includes; a wrong-fit return that becomes a chargeback is usually not fraud.
Financing high-ticket builds
A shopper pricing a leveling kit, wheels and tires for a half-ton truck can easily reach $3,000. Showing a monthly figure on the product page often keeps that shopper from closing the tab. Three habits help.
- Layer your financing. Offer a prime lender such as Affirm, and a waterfall such as PayTomorrow for shoppers who are declined, so one credit decision does not end the sale.
- Show it where the decision happens. Put the monthly estimate on product pages above a price you choose, not only in the checkout payment step.
- Explain the terms plainly. State that financing is provided by a third party, and say when a plan is a lease, so the buyer is not surprised by the total.
Fraud on high-value orders
A typical fraud order in this industry looks like this: a new account buys a $2,400 turbo kit with overnight shipping, the billing address is in one state, the ship-to is a freight forwarder in another, and the email address was created last week. Any one of those signals can be innocent. Together they are worth a hold.
- Check address (AVS) and card code (CVV) results on every order, and decline or review mismatches above a dollar amount you set.
- Score orders with a fraud tool: Stripe Radar, Authorize.Net’s Advanced Fraud Detection Suite, Kount, or a service such as Signifyd that covers the loss on fraud orders it approved.
- Keep a review queue for orders over your threshold, and call the buyer before you ship when something does not add up.
- Require a signature on delivery for expensive parts, so you have proof of delivery if the cardholder disputes the charge.
Chargebacks from wrong-fit returns
Many parts chargebacks are not fraud. A buyer orders a tonneau cover for the wrong bed length, the cover does not fit, and instead of asking for a return the buyer disputes the charge as “not as described.” You pay the dispute fee whether or not the part comes back.
- Confirm fitment before checkout. Year, make and model lookup plus qualifier questions, such as bed length or engine, cut the orders that turn into disputes.
- Show the return policy on the product page and in the order confirmation, and answer return requests fast. A buyer who gets a quick reply is less likely to call the bank.
- Save the vehicle the shopper selected with the order. If a dispute comes in, that record and the product’s listed fitment are your evidence.
If fitment is the root cause, PartsLogic Smart Search adds fitment-aware search to Web Shop Manager stores and to Shopify and BigCommerce stores.
PCI: keep card numbers off your server
PCI DSS is the card industry’s security standard, and it applies to any store that takes cards. The simplest way to keep your part of it small is to never handle card numbers yourself. Hosted, tokenized payment fields from Stripe, PayPal or Authorize.Net, and wallet payments through Apple Pay and Google Pay, send card data straight to the processor. Your store only sees a token.
That keeps your checkout PCI-aligned, but it does not make a store compliant on its own. You still complete a yearly self-assessment questionnaire, keep admin logins protected, and keep the rest of the site patched. Your processor can tell you which questionnaire applies to you. On Web Shop Manager, the Stripe integration tokenizes card data in the checkout, so card numbers do not touch the store’s server.
Frequently asked questions
What is the best payment processor for an auto parts store?
There is no single best one. Stripe and Authorize.Net both publish 2.9% + 30 cents card pricing in the US, Stripe with no monthly fee and Authorize.Net with a $25 monthly fee that includes fraud filters. Most parts stores pair one card processor with PayPal, Apple Pay and Google Pay, and add financing if they sell high-ticket parts.
How can I offer financing on wheels, tires and lift kits?
Add a buy now, pay later or financing provider at checkout. Affirm offers Pay in 4 and monthly plans to shoppers who pass its credit check. PayTomorrow sends one application to several lenders, including lease-to-own, so near-prime and nonprime shoppers can get an offer too. Many parts sellers offer both.
How do I reduce fraud on high-value parts orders?
Check address and card verification results, screen orders with a fraud tool such as Stripe Radar, the Authorize.Net fraud filters or Kount, and hold orders above a set value for review when billing and shipping do not match or the address is a freight forwarder. Require a signature on delivery for expensive parts.
How do I keep wrong-fit returns from turning into chargebacks?
Confirm fitment before checkout with year, make and model search and qualifier questions, show the return policy on the product page, and answer return requests quickly. Keep the vehicle the shopper selected with the order, because it is useful evidence if a dispute is filed.
Am I PCI compliant if I use Stripe or PayPal?
Hosted, tokenized payment fields keep card numbers off your servers, which shrinks how much of your business PCI rules apply to. It does not remove them. You are still responsible for your own PCI self-assessment each year, and your processor can tell you which questionnaire applies to you.
Do Apple Pay and Google Pay cost extra?
Apple and Google do not publish a separate merchant fee for their wallets. Wallet payments run through your card processor at its normal rate, so the cost is the same as a card payment through that processor.
