Segment Reporting [Abstract]

Schedule of Reconciliation of Consolidated Net Income

The table below provides the significant expenses that are regularly provided to our CODM for our one segment, the required disclosable amounts that are included in consolidated net income, and a reconciliation to consolidated net income. In 2025, we have broken out acquisition-related costs as a separate line item, rather than including them in 'Other segment items'. Prior period amounts have been reclassified to conform with the current year presentation.

We expect to continue to generate a large percentage of our future revenue from our significant customers. There are inherent risks whenever a large percentage of total revenue is concentrated with a limited number of customers. Should a significant customer: (i) terminate or fail to renew their contracts with us, in whole or in part for any reason; (ii) significantly reduce the number of customer accounts processed on our solutions, the price paid for our services, or the scope of services that we provide; or (iii) experience financial or operating difficulties, it could have a material adverse effect on our financial position and results of operations.
