Choose Expense Categories That Stay Useful

Diagnostic goal: Design a small, stable category set that supports search and review without pretending to replace accounting advice.

Identify the failure before changing the record

For users cleaning up inconsistent expense labels, the target is to balance reporting usefulness with review simplicity. First determine whether the source is weak, the extracted value is uncertain, the document belongs to another transaction or the workflow context is missing. Correcting a field before identifying the cause can hide the evidence needed to prevent the same error.

Diagnostic 1: Start from the decisions users need to make

• Expected evidence: Each category has a clear meaning.
• Failure to rule out: Creating a category for every merchant.
• Resolution: Compare the untouched source with the structured record and document the smallest supported correction.

Diagnostic 2: Keep category names distinct and understandable

• Expected evidence: Reviewers apply the same vocabulary.
• Failure to rule out: Using overlapping names.
• Resolution: Compare the untouched source with the structured record and document the smallest supported correction.

Diagnostic 3: Create an exception category for genuine uncertainty

• Expected evidence: Uncertain items remain visible.
• Failure to rule out: Treating categories as final tax treatment.
• Resolution: Compare the untouched source with the structured record and document the smallest supported correction.
