High Volume Transaction Matching: The Engine Behind Reconciliation
For enterprise companies, fintechs, and retailers, "data volume" is the enemy of the finance team. When you are processing millions of transactions a month, Excel crashes, and standard ERP modules choke. The solution isn't more people; it's a dedicated high volume transaction matching engine. This post explains the technology that makes automated reconciliation possible at scale.
Why Volume Breaks Traditional Tools
Standard matching tools rely on simple logic: "Does Column A = Column B?" This works for 1,000 rows. But at 1,000,000 rows, three problems emerge:
- Performance: Queries time out or take hours to run.
- Complexity: The number of potential "false positive" matches increases exponentially.
- Data Drift: By the time the data is loaded and matched, it's already outdated.
The Power of "Many-to-Many" Logic
The hallmark of a true enterprise-grade matching engine is its ability to handle complex relationships.
One-to-One: Easy. One payment of $100 matches one invoice of $100.
One-to-Many: One bank deposit of $5,000 matches 50 invoices of $100.
Many-to-Many: This is the hardest. Three partial payments (totaling $3,000) match a bundle of 15 invoices (totaling $3,000). Only advanced algorithms can solve this puzzle without human intervention.
How Reconwizz Handles the Load
Reconwizz uses a proprietary in-memory matching engine designed for speed.
1. Parallel Processing
Instead of processing rows sequentially, our engine splits the dataset into chunks and processes them simultaneously. This allows us to match 1 million transactions in under 2 minutes.
2. Multi-Pass Logic
We don't just try once. The engine runs multiple "passes."
Pass 1: Exact Match (Reference ID + Amount).
Pass 2: Fuzzy Match (Date +/- 1 Day + Amount).
Pass 3: AI Probability Match (Suggesting matches based on historical patterns).
Scalability for Growth
Don't let your back office become the bottleneck for your business growth.
Whether you are launching a new product line or acquiring a competitor, you need a reconciliation tool that scales with you. Reconwizz provides the horsepower to handle infinite transaction growth without adding headcount.
