Invoice Tax-ID Checker
Bulk-verify invoice titles and tax IDs against the standard list. Flags mismatches and duplicates in seconds.
The problem
Hundreds of e-invoices a month with typo titles, wrong tax IDs, or duplicates. Eye-balling is slow and miss-prone.
The solution approach
A local tool. Import the invoice file + the company standard-title sheet; auto-flag mismatches and duplicates for batch return.
What you will end up with
- Import both Excel files; results in seconds.
- Red = title/tax-ID mismatch; orange = duplicate; green = ok.
- Click a row to see the exact diff highlighted.
- One-click export of the issue list with suggested actions.

[Goal]
Batch-compare invoice titles and tax IDs to a master sheet; surface mismatches and duplicates.
[Platform & Stack]
- Windows + macOS desktop; Electron + React + TypeScript; SheetJS
[Core Features]
1. Two import slots: invoice details and master title sheet. Auto-detect headers; user confirms via dropdown.
2. Rules: exact-match title + exact-match tax ID = pass; any mismatch = red; duplicate invoice number = orange.
3. Group results by status; click a row to see a per-character diff.
4. Top summary: passed / mismatched / duplicated / total.
5. "Export issues" button with a "suggested action" column.
[Visual Style]
- Light background, white cards, radius 16, generous whitespace.
- Primary button muted dark; secondary light gray.
- Follows system dark mode; system fonts.
[Robustness]
- All data stays on the local machine. Offline.
- Autosave; 7-day rolling backups.
- Friendly messages on bad input, never raw stack traces.
