Categorization Rules

What Are Categorization Rules?

Expert plan feature: Categorization rules are available on the Expert plan.

Rules let you define automatic categorization based on merchant name patterns. When a transaction's merchant name matches a rule's pattern, it is automatically assigned the specified category and subcategory.

How Rules Work

Rules are applied before AI categorization during the upload process:

1. Your rules are checked first (in priority order)
2. Learned merchant patterns from your previous corrections
3. AI categorization as a fallback

This means your rules always take precedence over AI suggestions.

Creating a Rule

1. Go to Rules in the sidebar
2. Click Add Rule
3. Enter a merchant pattern (substring match, case-insensitive)
4. Select a category and optionally a subcategory
5. Optionally add tags to auto-apply
6. Set the priority (lower number = higher priority)

Example Rules

Managing Rules

• Edit: Change the pattern, category, or priority
• Toggle active/inactive: Temporarily disable a rule without deleting it
• Reorder: Change priority by dragging rules up or down
• Delete: Remove a rule permanently

Merchant Patterns (Automatic)

In addition to your explicit rules, WonderFunds automatically learns merchant patterns from your corrections. When you change a transaction's category, WonderFunds remembers the merchant name and applies the same category next time.

These learned patterns have a confidence score that increases with each confirmation.
