CellSource

Finally, professional audit workflows for Mac and the Web.

CellSource is the lightweight evidence engine designed for modern accountants and auditors. Stop manually typing numbers from PDFs or taking vague screenshots that get lost in your workpapers. With CellSource, every number you bring into Excel keeps a permanent digital link back to its exact location in the source document.

Key Features:

• Click-to-Reference: Open any PDF in the sidebar, select a number or text, and instantly drop it into your active Excel cell.
• Instant Traceback: Reviewing a workpaper? Just click the cell, and CellSource automatically re-opens the PDF and scrolls exactly to the source snip.
• Cross-Platform Native: Works perfectly on Excel for Mac, Excel on the Web, and Windows. No remote desktops or clunky virtualization required.
• Privacy by Design: Your client data stays yours. CellSource processes documents locally in your browser—files are not uploaded to our servers.

Perfect for:

• Vouching and Tick-and-Tie
• Financial Statement Verification
• Invoice Processing
• Tax Workpaper Preparation

Note: CellSource requires a free account to sync evidence.
