Merchant Solutions Average Transactions per Second measures Fiserv's disclosed average merchant transaction throughput.
Fiserv disclosed about 10,000 average merchant transactions per second across its merchant franchise.
Why it matters
Average transaction throughput provides an operating-scale view that complements annual GPV and merchant-location counts.
Investor caution
Throughput is a processing-scale metric, not a revenue measure, and transaction mix and value can vary materially across channels and merchants.

Part of the Merchant Solutions Operating Economics
Connect business-line revenue mix, segment growth and operating profitability, global payment volume, merchant footprint, Clover scale, and transaction throughput to understand merchant-solutions economics.
How the model fits together
- Business-line revenue mix: Small Business, Enterprise, and Processing revenue decompose Fiserv's Merchant segment into its principal operating lines. Small Business includes Clover and related acquiring, software, and value-added services; Enterprise spans large-client omnichannel commerce; Processing serves financial institutions, joint ventures, and resellers. These are issuer-defined business lines, not standardized peer segments.
- Merchant scale and throughput: Global GPV shows payment-value scale, with card and other payment volume separating the disclosed mix. SMB locations and Clover merchants show installed-base reach, while average transactions per second and peak transactions-per-second capability show processing throughput. GPV is not revenue, merchant counts are not interchangeable with locations, and peak throughput is disclosed capacity rather than sustained utilization.
- Segment growth and profitability: Merchant segment revenue and revenue growth establish the top-line trajectory, while operating income and operating margin show reported profitability and operating-margin change shows year-over-year leverage. Fiserv attributed the 2025 margin decline primarily to higher distribution-partner payments and data-processing costs, while reported operating income also benefited from an $89 million merchant-contract gain.
