Debit_card_assumptions_FY25_.pdf

This is a debit card transaction assumptions document for fiscal year 2025 prepared for the County of San Mateo Treasurer-Tax Collector's Office in support of a Merchant Credit Card Services procurement. The document presents historical transaction data across multiple county departments and agencies, including the Public Health Laboratory, Mobile Clinic, County Recorder offices, Parks Marina, Edison Clinics, and VRS Catering Connection. The data compares transaction volumes and sales values between August 2024 and March 2025, calculating monthly and annual averages to project expected payment processing activity. The assumptions presented establish a baseline for evaluating vendor proposals and understanding the scope of merchant card services required across county operations, with the service contract targeted to commence December 1, 2025, and extend through November 30, 2028.

Based on historical transaction analysis, the document indicates aggregate annual debit card transaction volumes of approximately 10,218 transactions generating $461,520 in annual sales across all participating county departments. The grand totals reflect combined monthly averages of 851.5 transactions valued at $38,460, with the San Mateo County Recorder Special operations representing the largest transaction volume at 281.5 monthly transactions averaging $14,625.71 in sales. These assumptions provide the quantitative foundation for the county's request for proposals, enabling potential vendors to assess processing requirements, fee structures, and service capacity needed to support county payment operations across multiple locations and departments during the proposed three-year contract term.
