CreditCardCategoryMismatch: Expense Classifier
Automatically detects when credit card transactions are miscategorized by banks, helping personal finance enthusiasts and accountants catch tax deductions and budget tracking errors.
The Problem
Credit card issuers often miscategorize transactions (e.g., marking a hardware store purchase as 'General Merchandise' instead of 'Home Improvement'), causing users to lose track of deductible expenses, misallocate budgets, and miss cashback category bonuses. Existing tools like YNAB and Mint rely on manual rules or poor ML, leaving systematic misclassification invisible.
Target Audience
Self-employed professionals, small business owners doing personal accounting, and detail-oriented individuals optimizing tax deductions and rewards.
Why Now?
Tax season friction is annual, AI classification is now fast/cheap enough to run retroactively, and recent interest in tax optimization (crypto losses, home office) makes deduction capture valuable.
What's Missing
Banks optimize categories for their own rewards programs, not user accuracy. No third party audits the mismatch and highlights lost deductions or cashback.
