Totals you can trace back to the receipt.

Budgets and transactions become a live Univer workbook. Every total is re-checked to the cent whenever a cell changes, and every figure links back to the rows it came from.

How it works
Built on Univer Sheets

The workbook is a real, editable spreadsheet. ProofLine checks its totals separately, to the cent.

Hover or tap a piece of the wheel

Four parts, and only one of them certifies the numbers.

The spreadsheet is for editing. The cent engine is for checking. Ant Ling only writes words, and every figure in those words comes from a checked total.

  • Univer Sheets

    The editable workbook. Cells, formulas, charts and saved versions run on Univer’s spreadsheet engine.

  • Cent engine

    Recalculates every total in whole cents from the source rows, separately from the spreadsheet formulas.

  • Your approval

    An edit puts totals on hold until they re-check. Deleting or moving rows keeps them on hold until a fresh import.

  • Ant Ling

    Drafts the report wording from checked totals only. Every figure is inserted by the cent engine.
