A guest post by CelereTech — Managed IT for growing SMBs
The ClickWerxs team recently published a checklist on how to vet a payment processor the way you vet an MSP. It's one of the clearest frameworks we've seen for holding payments vendors to the same standard as any other mission-critical infrastructure vendor, and it maps closely to how CelereTech approaches IT due diligence with our own clients.
The reason that framework works: payments and managed IT are not separate vendor categories. They share infrastructure, they share risk, and when one fails, the other usually takes the blame.
This post covers the other side of that relationship — why your payment processing reliability depends, more than most business owners realize, on the health of the IT environment running underneath it.
1. Payments run on IT infrastructure, not beside it
When a payment terminal goes offline, the first call usually goes to the processor. When a hosted payment page throws an error, it goes to the web host. When a chargeback spike appears after a fraud event, the conversation starts with the bank.
IT rarely enters the picture. Which is a problem, because IT is often where it actually started.
Here's how payment systems actually sit inside a typical SMB environment:
- The terminal or POS device is a network endpoint, managed or unmanaged, on your local LAN or Wi-Fi.
- Hosted payment forms depend on browsers and operating systems that need to be current, uncompromised, and not intercepted by malware.
- Payment APIs in CRM and accounting platforms authenticate through identity credentials that live in your Microsoft 365 or Google Workspace environment.
- Recurring billing tools send and receive data through cloud services that depend on your network DNS, firewall rules, and endpoint configuration.
Your processor can have interchange-plus pricing, next-day funding, strong chargeback support, and clean uptime SLAs. Your payments operation can still fail if the IT layer underneath it is unmanaged.
2. The three IT failure modes that break payment operations
We see three failure categories come up most often in payment and revenue disruptions for SMB clients.
Unmanaged endpoints
Any device that touches a payment workflow is an endpoint: a front-desk PC running your POS, a laptop that logs into your billing platform, a phone used for card-present transactions. Unmanaged endpoints running outdated software, without endpoint detection and response (EDR), are the most common entry point for the malware and credential theft that leads to payment fraud.
The ClickWerxs checklist raises PCI scope as a key question to ask your processor. That's the right question. What it can't cover is the IT-side answer: your PCI scope gets smaller when your processor uses tokenization and hosted payment forms, but it never reaches zero. The SAQ you fill out still asks whether your endpoints are protected, patched, and monitored. If your MSP can't confirm that, your PCI self-assessment has a gap regardless of what your processor provides.
Identity and access no one is watching
Payment platforms, CRMs, billing portals, and banking integrations are all protected by credentials. In most SMBs, those credentials live in a Microsoft 365 or Google Workspace tenant that's never had a full identity audit — no conditional access policies, no MFA enforcement across every account, no one checking whether former employees still have active logins.
A compromised credential doesn't look like an IT incident at first. It looks like an unauthorized transaction, an unexpected ACH transfer, or a spike in declined payments after an attacker tests stolen card data against your billing system. By the time it's flagged as a security event, the damage is already in the chargeback queue.
Network instability and connectivity gaps
The ClickWerxs framework asks about processor uptime over the last 12 months, a question almost no SMB thinks to ask. There's a parallel question worth asking about your own network: what was your uptime last year?
Consumer-grade routers on business networks, unmonitored internet circuits with no failover, DNS configurations untouched since the building was first set up — these are routine findings in SMB IT environments. Any of them can produce payment processing outages that look, from the outside, like a processor problem. We've walked clients through post-mortems on terminal connectivity issues that turned out to be a $40 router that should have been replaced three years earlier.
3. PCI compliance is a shared responsibility, and the IT half is often missed
This is where the liability becomes concrete.
A good processor will reduce your PCI scope through tokenization, point-to-point encryption (P2PE), and hosted payment pages. This shifts a significant chunk of the technical compliance burden onto the processor's infrastructure and shrinks the self-assessment questionnaire you need to complete each year.
It doesn't eliminate your IT-side obligations. Even under the most favorable SAQ-A scenario — where your only cardholder data environment touchpoint is a fully outsourced hosted payment page — you still have to:
- Maintain secure, up-to-date systems on any device that could access or influence the payment flow
- Ensure your network doesn't expose cardholder data in transit through misconfigured DNS or unencrypted traffic
- Control access to payment-adjacent systems with strong authentication and access logging
- Maintain a documented incident response plan that covers payment-related data exposure
Most SMBs in the SAQ-A or SAQ-A-EP category are handling the processor side reasonably well, especially if they've followed the kind of guidance ClickWerxs provides on choosing a processor with strong technical controls. The IT side is where the gaps show up.
Your MSP should be able to tell you which SAQ type your current IT configuration supports and what would need to change as your payment volume or product mix grows. If that conversation hasn't happened, it's overdue.
4. Business continuity means revenue continuity
Most IT business continuity planning is about data backup, disaster recovery, and restoring operations after a failure. Those are the right things to plan for. They're not the whole picture.
Revenue continuity — the ability to keep invoicing, collecting payment, and accessing transaction history during a disruption — depends on layers a traditional recovery plan doesn't cover:
- Can your team access your billing and payment platform if your primary office is unavailable?
- If your primary internet circuit goes down, does your payment terminal have a failover path?
- If your Microsoft 365 environment is hit by ransomware, how long before your team can authenticate into your payment portal?
- If you need to switch processors in an emergency, do you have documented access to your transaction history and recurring billing data?
That last question connects directly to the ClickWerxs framework, specifically the due diligence points around data portability and exit terms. The ability to migrate away from a processor quickly matters most in an emergency. That migration goes faster when your IT environment is documented, your credentials are managed, and your team isn't dependent on a single location.
Ransomware is still the most common and most financially damaging cyber threat facing SMBs. It can lock an organization out of every local system at once. Businesses with managed IT environments typically recover in hours to days. Without managed IT, that window stretches to days or weeks — when recovery happens at all. You don't get that revenue back.
5. What managed IT should actually cover
If you're evaluating an MSP, or taking a harder look at the one you already have, here's what adequate coverage looks like when payment processing is mission-critical.
Every device that touches a payment workflow should be enrolled in a managed endpoint platform, running current OS and application patches, and protected by an EDR solution that detects behavioral threats — not just known malware signatures.
MFA should be enforced on every account, with conditional access policies that block authentication from unmanaged or high-risk devices. Access reviews should happen regularly — not just offboarding, but periodic audits of vendors and contractors too.
Network hardware should be business-grade with monitored uptime. Where payment volume warrants it, a secondary internet circuit or LTE failover should keep terminals online when the primary circuit fails.
Backups should be encrypted, off-site, and tested on a quarterly schedule. The recovery sequence should explicitly include restoring access to payment and billing platforms — not just file servers.
Security awareness training should cover payment fraud scenarios specifically: fake vendor emails, invoice manipulation, and social engineering targeting billing staff. Generic phishing simulations miss the threat pattern that actually hits payment operations.
Finally, someone should own a current inventory of every device and every service account, reviewed at least quarterly. That inventory is the foundation of both PCI compliance and ransomware recovery. Without it, you're guessing.
If your MSP can't describe specifically how they're covering each of these areas, you have the same kind of gap in your IT vendor evaluation that the ClickWerxs checklist is designed to help you close on the payments side.
Evaluate both sides
The ClickWerxs 10-point payment processor checklist applies real vendor evaluation discipline to a part of the business most SMBs assess casually. The same discipline — asking for uptime numbers, reading exit terms, finding out what support looks like at 7pm on a Saturday — applies to every vendor running mission-critical infrastructure for your business.
Your MSP belongs on that list. They share infrastructure and risk with your payment processor. A gap in either one creates exposure in both.
