Building a Personal Accounting App Instead of Using Paid Tools

After designing with tools like Claude, the author created a personal accounting app. It classifies transactions and leaves ambiguous items in a review queue.

How it works

  1. They made a broad plan with ChatGPT, refined it with Claude, and checked missing parts with Codex.
  2. They built and operated an app that imports bank transactions and classifies them by category.
  3. User corrections are saved as rules for future classifications.

Results

The author uses this app to organize transactions for a small business.

Notes

They found connecting to bank data challenging. The app's records are also reviewed by a professional.

Example prompt · Claude

Please create a local ledger app that separates and manages personal expenses and business transactions.

Input: My operating system [environment], sample transactions [CSV], account and classification criteria [list], required reports [items]. First, review the format of the current data and the fields needed for the ledger, then write an implementation plan. Leave any unclear accounting criteria as questions for clarification.

Implement, in order: importing transactions, suggesting classifications, human review, and search/summary screens. Separate personal and business records, and leave low-confidence classifications in a review queue. When I correct a classification, make it possible to see what rule was saved for future transactions.

For connecting to bank data, first check which services are actually available and what permissions are needed. The initial version should work with the provided sample, and prepare original transactions, edit history, and backup/restore methods. Do not include tax filing or fund transfers in this task.

Deliverables: a working app, instructions for importing data, classification rules and validation results. Test with duplicate transactions, canceled transactions, mixed personal/business items, and ambiguous classifications, and compare input totals with report totals.
