Why Payment System Downtime Can Hurt Your Business (and How to Prevent It)

Why Payment System Downtime Can Hurt Your Business (and How to Prevent It)
By alphacardprocess July 14, 2025

Downtime of the payment gateway can potentially harm your business by inducing lost sales, enraging customers, and ruining your reputation. At a time when customers want instant and easy payments, an outage will shift them to your competitor. For this reason, one has to find out why downtime occurs and make decisions to avoid it, ensuring your revenue and confidence remain steady among customers.

How Payment Gateway Works

A payment gateway processes online transactions securely by encrypting customers’ data and transferring this data to the acquiring bank, which triggers authorisation from the cardholder’s issuing bank. After being validated, the gateway notifies the company to complete the purchase. Funds are deposited into the merchant account at the end-of-day. The system keeps payments quick, secure, and reliable, allowing businesses to process transactions efficiently without disrupting customers’ data.

Causes of Payment Systems Failures?

Payment error

Payment gateways and payment systems can fall behind for a number of reasons that directly impact businesses, ranging from lost sales to reduced customer trust. Technical failures like server crashes, software bugs, or network connectivity issues can tarnish service instantly. Scheduled maintenance and system upgrading, can fix these issues temporarily, even if it’s inevitable to prevent it altogether, but ensuring regular maintenance can ensure the downtown occurs in scheduled time. 

Cyber attacks or suspected fraud attempts can result in the temporary closure of providers as a precautionary action. High transaction volumes during busy periods, such as festive seasons or massive sales events, can cause system overload and result in delay or downtime. Payment gateways also include third parties like banks, hosting companies, or Internet services, and failure of any of these partners will impact the payment system.

Finally, data centre issues—resulting from equipment malfunctioning, electrical outages, or natural calamities—will also interrupt payment services. This shows how complex infrastructure management is important for smooth online payments.

Minimizing Payment Gateway Failure Risks

Payment gateway failure threatens serious risks to online ventures by initiating transaction delays and customer discontent, this is why several methods need to be implemented to minimize risks of payment downtown. Several new payment trends and alternative payment methods facilitate diversion of payment transactions through a standby system in the event of failure of the main system, facilitating business continuity with no hiccups. Checking and monitoring of hardware, software, and network facilitate the identification of faults early and fault correction prior to faults developing into major issues. 

Proper fraud protection through employee training and maintenance of systems avoids the payment systems from being the subject of an attack that may cause outages. Choosing a reliable payment provider with a solid track record and rapid support offers an added level of protection. Finally, gaining visibility into maintenance windows allows companies to forecast and warn clients, avoiding downtime during unavoidable hours.

How to Manage Payment Gateway Outages Effectively

No company is entirely free from the likelihood of payment gateway failure, even with stringent security controls in place, and hence, there should be a good response plan ready. During an outage, the companies must tell customers in simple English what is happening, apologize for the disruption, and provide an opinion on when the situation will be rectified. Remaining in regular contact with the payment provider is also important in order to figure out what is happening, urge an expedient resolution, and discover any potential workarounds. 

Having alternative payment mechanisms available, such as another gateway or manual payments, avoids transactions being locked up in the event of one system being offline. After an outage, businesses need to look at what failed, how the response was carried out, and what can be done to better plan and manage the customer more efficiently in the future. Communication, backup facilities, and continuous improvement all serve to reduce the effect of an outage.

The Cost of Payment Downtime to Finance

Businesses financial impact

Payment system outages are costly to businesses in a variety of ways. The most readily apparent is lost revenue. For instance, if a bank handles 120 transactions a second, with an average value of $85 a transaction, and has 210 minutes of downtime, it may lose over $128 million in transactions and incur approximately $3.2 million in merchant fees alone. Aside from lost sales, downtime also affects cash flow for those companies doing business online, which require continuous high-volume transactions to pay their suppliers and fund day-to-day costs. 

Companies can be forced to pay these deficits in cash through credit. Disturbances also incur compensation costs when companies give refunds or discounts to upset customers, and technical recovery costs to fix the problem and improve security. Maybe worst of all is reputation damage, customers expect smooth payment processing, and any hitch will spread rapidly on social media, eroding trust and creating a bad reputation that lasts long past systems recover.

Major Example of Payment Downtime

High-profile payment outages highlight the cost of downtime. For example, in the 2018 Visa outage, close to 5 million payments were declined in Europe over a period of 10 hours, infuriating millions of customers. Such events typically break the customers’ confidence to the extent that it becomes harder and more expensive for businesses to regain customers’ loyalty and win new customers. Affecting merchants can spend more on customer service and pay, as well as advertising, to regain trust. 

Another example is during 2023, a global Square outage caused many U.S. businesses to resort to taking payments in cash, slowing sales and disrupting operations. A similar global IT breakdown in July 2024 shut down payment systems worldwide due to a cyberattack, and many organizations were not equipped to process payments manually. These examples show that, besides technology solutions, organizations should also have well-established business continuity planning, good communication practices, and investment in more secure payment systems to protect both revenue and image when things go wrong.

How to Reduce Downtime in a Small Business

For small businesses, time out of commission is expensive, but dangers may be kept at bay with proper planning. An excellent place to begin is migrating vital tools and information to safe cloud-based environments, normally constructed with high availability and defense in mind. Planning for regular hardware and software avoids systems from becoming creaky. Recognizing that small businesses are high-value attack points for cybercrime means accepting regular data backups, which are best performed automatically and in the cloud.

Having a well-established business continuity and disaster recovery (BCDR) plan means everyone understands what to do in case of an outage; maintain hard copies during emergencies. Having service-level agreements (SLAs) with clients and suppliers helps to set expectations. In the case of internet reliability, having an alternative method like a cellular hotspot can keep businesses online even at the time of any downtime.

Identify single points of failure on a regular basis and create responses to threats. A valid professional risk assessment can uncover latent weaknesses and recommend enhancements. Lastly, verify if your vendor has industry compliance standards on an ongoing basis to provide an added safety and reliability function. All these steps collectively can assist small businesses in being ready and recovering quickly.

Downtime Costs

Downtime expenses range by company size and the number of hours systems are down. Statista indicates most companies polled, 25% put the server per-hour value of downtime between $301,000 and $400,000. IDC approximated infrastructure failure for Fortune 1000 to cost up to $100,000 an hour, with unplanned annual downtime losses up to $2.5 billion. For SMEs, in an Infrascale survey, it was discovered that while 10% of them are losing more than $50,000 per hour in downtime expenses, the majority of them had $10,000 and $40,000 per hour of downtime expenses. Even minutes of downtime tend to cost very quickly, and any business should plan and insure for downtime risk.

How to Calculate the Cost of Business Downtime

If one understands the actual cost of downtime, it can go even further to show just how priceless a BDR plan is. To determine it, start with lost revenue—find out how much business your company tends to bring in each week or each month, and calculate how much you’ll lose each hour when the systems are down. Next, add lost productivity by counting up hourly pay and calculating how much work can’t be done during downtime.

Insert the cost to recover, which can include fixing or replacing malfunctioning hardware, replacing lost data, and any periodic cost of the downtime. Finally, include reputational loss, customer dissatisfaction, and the longer-term cost of lost confidence.

With these numbers at hand, insert them into the formula:

Cost of Downtime (per hour) = Lost Revenue + Lost Productivity + Cost to Recover + Cost of Intangibles

This simple calculation puts quantifiable figures on the possibility of downtime and makes the argument for BDR planning in advance more transparent to everyone. 

Types of Downtime

Downtime is generally of two types: planned and unplanned. Planned downtime is planned ahead, usually during weekends or off-peak times, and does not interfere with business as usual. It could be for updates, patching the software, or testing. Being established and planned, planned downtime does not damage business but rather keeps systems in running order by addressing issues before they become more severe consequences.

Unintended downtime comes suddenly and unexpectedly, most of the time as a result of technical issues, human mistakes, cyberattacks, or even natural disasters. The downtime may be greatly felt in business operations and result in lost revenues and consumer trust. Although it cannot always be prevented, an effective business continuity plan and systems for backup can reduce its impact and serve in any way possible during unforeseen disruptions.

Other Costs and Downtime Effects

Aside from outright monetary loss, downtime causes several business-critical effects. It is likely to lead to lost productivity as workers are not able to use state-of-the-art equipment or machinery and have to sit idle until processes become available again. Downtime can also lead to missed business opportunities when customers cannot access products or get immediate support, leading them to seek alternatives. 

One downtime can damage a brand’s reputation and make the company appear unreliable, with accompanying negative comments and eroding customer trust. Downtime will also increase the stakes in terms of data loss; outages or attacks by surprise can cause corruption or leakage of sensitive data, resulting in security weaknesses that attackers can exploit. All these aggregated effects illustrate why short downtimes take a long-term toll on operations and reputation.

Strategies to Monitor Downtime

Downtime can strike any business at any moment, which makes preparation very essential. Preparing a disaster recovery plan and using a quality BCDR solution ensures services remain uninterrupted. Upgrading to the latest software, installing security patches, and backing up data on a regular basis keep systems protected and recover data in no time. 

Monitoring software helps to catch issues early, and the chances of catastrophic failure are reduced. Since human error is also one of the major causes of downtime, adherence to IT policy and training staff to recognize cyber threats becomes vital. All these steps can go a long way in restricting downtime and protecting your business from interruption and loss of finances.

Conclusion

Payment system downtime can equate to enormous losses in finances and loss of customer trust. But best practices like new software installations, deployment of backup systems, training of employees, and advanced planning can allow companies to manage risks and respond to outages more effectively while maintaining business and customer satisfaction.
