Integrating Payments With Shop Management Software (Tekmetric, Shopmonkey, Mitchell 1)

Auto repair shop software payments work best when the card terminal, text-to-pay links and your shop management system share one record, so every payment lands on the right repair order without anyone retyping it. Tekmetric, Shopmonkey and Mitchell 1 each offer a built-in or partner payment option, and the convenience is real. The question worth asking is what that convenience costs you, and how to check it before you sign.

What "integrated payments" means for an auto shop

In a non-integrated shop, the service writer rings up the total in the shop management system, then keys the same amount into a separate card terminal. Someone matches the two at the end of the day. When the numbers don't line up, because of a typo, a split payment or a deposit taken on a different day, that someone spends time hunting it down.

With integrated payments, the shop system sends the amount to the terminal or the payment link, and the approval comes back and posts to the repair order on its own. The practical benefits are:

• No double entry. The amount is never retyped, so you don't get a $1,250 ticket charged as $125.
• Deposits and partial payments stay with the job. A parts deposit taken by text on Tuesday shows up against the same repair order when the car is picked up Friday.
• Cleaner books. Payments, fees and refunds can sync to QuickBooks or other accounting software instead of being entered by hand.
• Fewer card numbers floating around. When customers pay on a terminal or a hosted link, your staff doesn't handle raw card data, which helps with PCI.

Our complete guide to credit card processing for auto repair shops covers the full payment picture. This post focuses on the software side: what each major platform offers and how to evaluate it.

How Tekmetric, Shopmonkey and Mitchell 1 handle payments

All three platforms want to process your cards, because payments are a meaningful revenue line for shop software companies. Here's what each one says publicly, based on their own product pages and announcements.

Tekmetric Payments

Tekmetric's payment product (formerly marketed as Tekmerchant) is described on its site as a fully integrated system built on Stripe infrastructure, with fraud screening through Stripe Radar. Its support documentation describes taking card-present payments on a terminal from the Payments tab of the repair order, keying card-not-present payments, and sharing an invoice by text or email for text-to-pay. Tekmetric says payments tie to repair orders, invoices and customer records, that refunds and disputes are handled inside the software, and that it offers next-day funding, with daily, weekly or monthly payout schedules and instant payouts for some shops. Consumer financing is available through Affirm, Klarna and Sunbit. Tekmetric confirms there are transaction fees but asks shops to book a demo to review rates.

Shopmonkey Payments

Shopmonkey Payments is also powered by Stripe. Stripe's customer story says Shopmonkey runs on Stripe Connect and uses Stripe Terminal card readers. Shopmonkey's quick start guide lists card readers with contactless payments, text and email invoices, built-in surcharging, Sunbit and Affirm financing, and integration with over 30 accounting packages. It says there are no monthly fees to accept payments, that you pay per transaction, and that most payouts arrive within two business days, with instant payouts available. The same guide is blunt about risk: shops are liable for losses when stolen card credentials are used, and disputed amounts can be deducted from future payouts. Stripe's write-up notes that Shopmonkey offers interchange-plus pricing to enterprise and high-volume customers, which tells you pricing is negotiable at some volume.

Mitchell 1 Manager SE and 360 Payments

Mitchell 1 took a partner route. In March 2025 it announced an integration between Manager SE and 360 Payments, listing text-to-pay (including after-hours vehicle pickup), consumer financing, PCI compliance support, business capital and a checkout that combines receipts, digital signatures and repair orders. Mitchell 1 has also integrated with other processors over the years. Pricing isn't published; shops sign up through 360 Payments.

Features and terms change, so treat this table as a starting point and confirm the details in writing with each vendor.

The real cost question: convenience vs. rate

Integration doesn't change the biggest piece of your processing cost. Interchange, the fee paid to the bank that issued the card, is set by Visa, Mastercard and the other networks, and it's the same whether the payment runs through your shop software or a standalone terminal. What varies is the markup your processor adds and how it's structured.

That's where bundled software payments deserve a closer look. Many software-embedded processors quote a blended or flat percentage. That's simple to understand, but on large repair tickets a few tenths of a percent adds up quickly. Here's a worked example using round numbers, not any vendor's actual rate:

We walk through flat-rate and pass-through pricing in detail in interchange-plus vs. flat-rate pricing. The short version: interchange-plus shows you the real wholesale cost and the processor's markup as separate numbers, which makes it much easier to tell whether you're getting a fair deal. Shopmonkey's own case study says interchange-plus is offered to high-volume customers, so it's reasonable to ask any software vendor whether it's available to you.

How the payment is taken matters too

Integration makes it easy to send text-to-pay links, and that's useful when a customer isn't at the shop. But a link is a card-not-present payment, which carries higher interchange than a chip or tap at the counter. If your team starts texting links to customers who are standing at the desk, your costs creep up. Our post on text-to-pay for auto shops explains when links make sense and when to dip the card.

Fleet and commercial cards

If you service fleet vehicles, check whether the integrated processor can pass the line-item data that commercial card rates depend on. Visa's Commercial Enhanced Data Program now ties its best commercial-card interchange to detailed transaction data, and a repair order already holds the parts and labor lines. Whether that data actually reaches the processor depends on the integration. Our fleet card processing guide covers WEX, Voyager and Corpay cards and the data rules in more depth.

Questions to ask before you switch on integrated payments

Before you sign a payments agreement through your shop software, get clear answers to these questions, ideally in writing:

• What is the pricing model? Flat rate, tiered or interchange-plus? Is interchange-plus available at your volume?
• What are all the fees? Per-transaction, monthly, PCI, chargeback, terminal rental or purchase, instant payout and early termination fees.
• Who is the processor and who holds the merchant agreement? Is it the software company, a payment facilitator or a separate acquirer?
• Can I use my own processor? If you'd rather keep your current merchant account, ask whether the software supports an outside processor and what features you lose.
• How fast is funding, and what does faster cost? Compare standard payout timing with any instant-payout fee.
• How are chargebacks handled? Who manages disputes, what does each cost, and can funds be held or deducted from payouts?
• Is the contract tied to the software subscription? If you leave the payment program, does your software price change, or vice versa?
• Do you support surcharging or cash discounting, and is it compliant? Ask how the system handles state rules, debit cards and notices.

The answer to "Can I use my own processor?" varies by platform and can change. Some systems strongly favor their own payment product, and some partner with outside processors. If your preferred processor isn't supported, you can still run a standalone terminal, but you give up hands-free posting to the repair order. Weigh that labor against the rate difference.

Surcharging through shop software: the Colorado angle

Several shop platforms now include built-in surcharging, and Shopmonkey lists it as a payment feature. A software toggle doesn't make a surcharge legal, though. Card network rules still apply: surcharges are for credit cards only, not debit, and they come with disclosure and notice requirements. State law can be stricter.

In Colorado, C.R.S. § 5-2-212 caps a credit card surcharge at 2% of the transaction or the merchant's actual processing cost, whichever is less, and requires a specific posted notice. If your software's default surcharge is set higher than 2%, a Colorado shop needs to change it. Our guide to auto repair credit card fees walks through the math on whether a surcharge or a better rate saves you more. This is general information, not legal advice; check current rules for your state.

How to decide: integrated, standalone or both

For most shops, integrated payments are worth having, because the time saved on posting and reconciliation is real and the error reduction protects your margins. The mistake is accepting the bundled rate without comparing it. A simple process:

1. Pull your last three processing statements and calculate your current effective rate: total fees divided by total card volume. Most statements list total fees in a summary box near the top.
2. Get a written quote from your software vendor's payment program, including every fee, not just the headline percentage.
3. Model both options on your actual volume and card mix, including large tickets, fleet cards and how many payments come by text link.
4. Put a dollar value on the time saved. If integration saves your office manager several hours a week, count it.
5. Check the exit terms before you sign, so you can change processors later without losing your software.
