MASD1001 Daily MAS Detail Export
The MASD1001 file is a Merchant Accounting System (MAS) daily detail report. It provides a row-per-fee-line breakdown of all fees and charges assessed against each merchant for a given settlement day across four categories: Card Brand Fees, Interchange, Individual Plan, and Discount. This is the primary file for daily fee reconciliation and margin analysis.

Cross-reference Interchange rows against the card brands' published interchange tables to verify correct program qualification. Compare daily totals with the monthly MASM1001 to confirm period-end accuracy.

Common Mistakes
- Summing
Incomeacross all rows without deductingExpense— always useTotal(Income − Expense) for net margin calculations. - Expecting
NumberandAmountto be populated on standard fee rows — these columns are0and0.00for assessment and interchange lines; useSalesNumber/SalesAmountinstead. - Confusing
Discountrows with0.00values as errors — when the discount is bundled into theIndividual Planrows,Discountlines legitimately carry zero values. - Not cross-referencing
Interchangeprogram names against card network tables — incorrect interchange qualification results in a different fee code than expected. - Comparing daily MASD1001 totals directly to monthly statements — use the MASM1001 monthly file for period-end reconciliation.
