Thousands of small businesses across the United States found themselves scrambling for new payment processing solutions following Bank of America's transition to Fiserv merchant services in 2018, a corporate restructuring that left many retailers without the ability to accept credit card payments for weeks or months.
The disruption began when Bank of America completed its acquisition of merchant services operations and transitioned existing accounts to Fiserv, a major financial technology company. The administrative overhaul, while intended to streamline operations, created significant barriers for merchants seeking to maintain their payment processing capabilities.
"We went from having a functioning merchant account to being told we needed to reapply through an entirely new system," said Maria Rodriguez, owner of a small restaurant in Phoenix. "The paperwork was overwhelming, and we couldn't process cards for three weeks while waiting for approval."

Industry analysts report that the transition affected approximately 50,000 merchant accounts nationwide. Many businesses faced lengthy re-underwriting processes, enhanced documentation requirements, and stricter approval criteria under the new Fiserv framework.
Complex Approval Process Creates Bottlenecks
The new merchant application process under Fiserv required extensive financial documentation, including tax returns, bank statements, and detailed business plans. Many existing merchants who had maintained accounts in good standing for years suddenly found themselves treated as new applicants.
"The due diligence requirements were far more stringent than what we had experienced previously," explained David Chen, a payment processing consultant who assisted dozens of affected businesses. "Merchants had to provide documentation dating back three years, even for established relationships."

The enhanced screening process was designed to reduce fraud and chargebacks, but it created significant delays. Average approval times extended from days to several weeks, leaving businesses unable to process electronic payments during the interim period.
Small Businesses Bear the Brunt
Small and medium-sized enterprises were disproportionately affected by the transition. Many lacked the resources to navigate the complex application process or provide the extensive documentation required by Fiserv's underwriting standards.
Restaurant owners, retail shops, and service providers reported lost sales during the transition period. Some businesses were forced to operate on a cash-only basis, while others sought alternative payment processors, often at higher rates and with less favourable terms.

"For a small business, losing the ability to accept credit cards is devastating," said Jennifer Walsh, executive director of the National Small Business Association. "Many of these merchants had excellent payment histories but were caught up in administrative changes beyond their control."
Industry Response and Ongoing Challenges
Fiserv representatives acknowledged the transition challenges but emphasized the long-term benefits of their enhanced risk management systems. The company implemented expedited review processes for existing Bank of America merchant clients and established dedicated support teams to handle the backlog.
However, many merchants continued to face difficulties well into 2019. Some reported recurring issues with account maintenance, unexpected fee structures, and communication gaps between Bank of America relationship managers and Fiserv technical support teams.
The merchant services industry has since adapted to more rigorous compliance standards, but the 2018 transition serves as a cautionary tale about the potential consequences of large-scale operational changes in payment processing infrastructure.
For businesses still experiencing challenges with their merchant accounts, industry experts recommend working with experienced payment processing consultants and maintaining comprehensive financial documentation to navigate the approval process more effectively.
