Transaction Matching Algorithms & Core Logic
Architecting deterministic rule engines, probabilistic scoring models, and multi-to-multi settlement matching algorithms.
Multi-Pass Deterministic Matching Pipeline
A high-performance matching pipeline executes hierarchical matching passes: Pass 1 matches exact unique reference IDs (UETR, trace number, order ID) and exact amounts; Pass 2 matches normalized account numbers, transaction types, and amounts within a +/- 2 day window; Pass 3 evaluates grouped batch sums for 1:N settlements.
Handling Complex 1:N and N:M Batch Cardinality
Payment processors bundle hundreds of payments into single net bank deposits. The matching algorithm must execute subset-sum and knapsack optimization logic to group internal transaction subsets that match the target lump sum, accounting for processing fee deductions.
Algorithmic Precision with the NAYA Proof Engine
The NAYA Proof Engine executes high-speed matching across complex multi-rail datasets, pairing deterministic precision with automated exception isolation, achieving up to 99% match accuracy and reducing manual review workloads.
Frequently Asked Questions
Common questions about this topic
QWhat is "Bundling" in transaction matching?
Bundling occurs when a payment processor aggregates a day's worth of sales into a single payout to your bank account. The matching engine must "unbundle" this by using the settlement report from the processor to reconcile the lump sum against individual sales orders.
QHow do you prevent False Positives?
By using "Cascading Logic." The system prioritizes high-fidelity matches (Unique ID) first. Only if that fails does it attempt lower-fidelity matches (Amount + Date). This hierarchy prevents a generic $50 transaction from being matched to the wrong user.
