Show HN: Tally – check a spreadsheet's numbers against their source, in-browser
3 hours ago
- Tally independently recomputes every figure from source data and shows which numbers match or mismatch with exact row proof.
- Users can drop a file or connect a Google Sheet; Tally marks each figure as verified or not with the underlying rows as receipts.
- Tally offers automated re-verification: it re-pulls connected sheets daily/weekly and alerts when data changes or figures stop tying out.
- Every verification generates a shareable 'Verified' link that lets recipients click any figure to see the source rows.
- A real example: Tally caught a $3,450 overstatement in a landscaping business's revenue report caused by a double-counted job.
- Tally can now reconcile reports against QuickBooks (read-only) and identifies mismatches with exact documents as proof.
