Why payment failures are costing more than you think

Written by Antom | Jun 26, 2025 2:24:59 AM

Payment failures are often shrugged off as technical blips. One retry, maybe two, and then it’s dismissed. But scratch beneath the surface, and a more complex picture emerges. Each failed attempt to process a payment can create a ripple effect across your entire financial operation. Missed revenue, fragmented reconciliation, and inflated operating costs don’t show up in a single line item, but they show up nonetheless. According to Pymnts Intelligence Report, across industries payment rejection rates can reach double digits so it doesn’t take long to chip away at margins. When the payment process breaks down, everyone loses—merchant, customer, and payment processor alike.

Key takeaways

  • Payment failures are more than just tech glitches—they're hidden revenue drains.
  • In some industries payment failure rates reach double digit percentages.
  • Key impacts include bank fees, manual rework, delayed cash flow, and lost sales.
  • Common causes range from bad data to legacy infrastructure and cross-border friction.
  • CFOs are addressing these with smarter validation, automation, and real-time processing.
  • Metrics like STP rates and revenue leakage help quantify the problem.
  • Antom supports merchants in making payment operations more resilient and efficient.

Beyond fees: what's really driving the losses?

The true cost of failed payments lies in the hidden, often overlooked friction:

  • Bank rejection fees: Each bounced payment carries a cost.
  • Manual exception handling: Teams spend time troubleshooting instead of focusing on analysis.
  • Delayed cash flow: Funds stuck in error states can disrupt liquidity.
  • Lost sales: Customers abandon carts after soft declines or give up after failed attempts.
  • Revenue leakage: Missed takings can amount to as much as for 8-11% of revenue depending on the industry.
  • Subscription drop-offs: Missed recurring payments due to expired cards or insufficient funds often result in involuntary churn.
  • Credit card rejections: Declines from card networks disrupt both user experience and merchant income.

Multiply these impacts across your transaction base, and they stop being marginal.

The silent killer: operational drag and staff strain

Every failed payment means another exception to manage. For finance teams already juggling month-end close and compliance reporting, chasing down failed transactions slows everything. Straight-through processing (STP) rates drop, reconciliation cycles stretch, and staff burnout creeps in. Operational inefficiency isn’t just a nuisance; it adds cost. It lowers trust. And over time, it makes you less responsive to both customers and suppliers.

What's causing all this?

Here’s where many businesses get tripped up:

  • Outdated or incorrect data: Mistyped IBANs, expired cards, and invalid account numbers cause automatic rejections.
  • Currency mismatches: Sending USD to a local currency account can trigger a block, especially with bank-specific rules.
  • Bank-specific quirks: Domestic clearing rules and regional routing preferences often go unnoticed until they cause a failure.
  • Soft declines: Temporary holds from the issuing bank due to fraud suspicion or spending limits.
  • Legacy infrastructure: Systems not built for modern transaction volumes and real-time authorisation can become choke points.
  • Cross-border friction: Issues multiply across jurisdictions. Payment networks may not interoperate cleanly. Local schemes might have requirements you’re unaware of.
  • Insufficient funds: A leading cause of failed payments, particularly with recurring payments where balances fluctuate.
  • Payment gateway errors: Inconsistent uptime and technical mismatches between systems can delay or block the payment process.

The result? Higher payment failure rates and operational strain that scales with volume.

Quantifying the fallout: metrics that matter

Understanding where the cost is hiding requires more than a single report:

What to track

  • Straight-through processing (STP) rate: This is your cleanest indicator of efficiency. If it falls below 90%, investigate immediately.
  • Cost per failed payment: Add up the direct fees, internal processing hours, and impact on customer support.
  • Revenue leakage: Estimate missed conversions linked to failed transactions. Segment by geography or payment method for insights.
  • Customer churn correlation: Look at the overlap between payment failure and churn. Even small overlaps can represent lost life time value (LTV).
  • Retry volumes: Track how often customers or systems retry payments. High retry rates suggest preventable friction.

Surface these insights regularly. Patterns here often reveal systemic issues that can’t be spotted on a daily dashboard.

Fixing the flow: modern strategies that work

1. Data validation tools

Use account verification and bank detail formatting checks to catch issues before they cascade into failures. Enriching payee data—down to bank-specific rules—saves both time and money. Valid payment details mean fewer delays and less manual correction.

2. Payment retry strategies

Set up automated retry logic that spaces out attempts and adapts timing to optimise success. Use machine learning to target retries only where the likelihood of recovery is high. For subscriptions or multiple payment attempts, smarter retry logic prevents customer churn.

3. Real-time alerts and notifications

Deploy real-time alerts to flag when a transaction fails, allowing rapid action. Alerting both internal teams and customers helps resolve payment issues while intent is still high. Timely nudges can prompt users to update their payment information before disruption occurs.

4. Pre-flight checks

Run proactive diagnostics before submitting a payment to reduce rejection. These checks assess routing, account validity, and transaction limits to avoid errors altogether.

5. Real-time payment methods

Consider shifting from card payments to real-time online payments for repeat and high-value transactions. These provide more control, fewer intermediaries, and lower failure risk. Alternative payment methods can also improve acceptance rates in specific markets.

6. Real-time processing

Speed isn’t just about convenience—it limits the window for failure. Real-time systems provide immediate visibility and faster reconciliation, enabling teams to step in before issues compound. This makes the entire payment process more transparent and resilient.

Antom works closely with merchants to implement these strategies—helping validate payment data, reduce retries, and integrate smarter routing logic. With tools designed to fit into your existing systems, Antom simplifies what can otherwise become a patchwork of manual fixes. Whether you're refining a payment gateway or replacing your payment processor, the goal is smoother flow and stronger recovery.

Looking ahead: turning risk into financial advantage

Failed payment costs don’t have to be accepted as normal. Tighter controls and smarter routing can recapture value you never thought was gone. Payment operations, once seen as backend plumbing, are becoming levers for revenue integrity and cost discipline.

Forward-looking teams are reframing payments as a financial performance driver. Every transaction is a moment to protect margins, preserve relationships, and retain revenue. When equipped with reliable data and responsive tools, finance teams can anticipate failure patterns, accelerate reconciliation, and reduce payment friction.

Modern CFOs are building payments into broader planning cycles—aligning payment strategies with cash management, risk exposure, and customer experience metrics. What once operated on the sidelines now sits close to centre-stage. With better tools and smarter strategies, the gains are there for the taking.

What forward-thinking CFOs are doing

The most effective finance leaders are not waiting for another failed batch to prompt action. They’re benchmarking STP rates, cutting cross-border transaction costs with local acquiring setups, and implementing data hygiene protocols. Some are deploying AI-assisted reconciliation to match payments faster, others are driving down retries with machine-learned risk scoring. Industry reports from McKinsey and Capgemini underscore this trend: payment operations are now viewed as strategic assets.

CFO checklist: key actions to take

  • Review STP rate monthly and investigate any dip below 90%
  • Identify top reasons for payment failures using internal and acquirer data
  • Audit existing billing retry logic and evaluate automation effectiveness
  • Integrate account and routing validation into onboarding and payout processes
  • Assess the impact of payment failure on churn and lifetime value
  • Evaluate feasibility of shifting recurring or high-value payments to A2A
  • Align payment data reporting with reconciliation and cash flow planning
  • Partner with payment providers offering proactive optimisation tools
