Redaction

Redact documents before buyers see them

Early in a sale you often need to share a contract without the customer's name, or a payroll file without the people. Stowbill lets you draw black boxes on a PDF and gives data room guests the redacted copy only. Your team keeps the original.

How redaction works

  • Open a PDF in your files and choose Redact.
  • Drag a box over each name, figure or clause to hide. You can work across every page.
  • Save. Stowbill builds a redacted copy and stores it next to the original.
  • Guests in the data room see and download the redacted copy. Your own team still opens the original.

The hidden text is really gone

A common mistake is to draw a black rectangle over text in a PDF editor. The words are still in the file, and anyone can copy them out. Stowbill avoids this by turning each page of the redacted copy into an image with the boxes burnt in. There is no text layer left to copy or search.

The price of that safety is that guests cannot search or select text in a redacted document.

A new version cannot slip past the redaction

If someone uploads a new version of a document that was redacted before, Stowbill holds the new version back from guests until a person redacts it again or confirms that it needs no redaction. Buyers keep seeing the last redacted version in the meantime.

What it does not do

Not built yet: single sign-on (SSO), page-by-page time analytics, AI features, accounting and email integrations, and a mobile app. Stowbill does not hold SOC 2 or ISO 27001 certification today.

  • Redaction is for PDFs. Convert Word or Excel files to PDF first.
  • There is no automatic search-and-redact for names or patterns yet. A person draws each box.
  • Removing a redaction later is done by sharing the original as a new step, for example once a bidder is preferred.

Questions

Can a buyer recover the text under a redaction?

No. Each page of the redacted copy is an image with the black boxes burnt in, so the hidden words are not in the file.

Does the firm keep the original?

Yes. The original stays in your files with its version history. Only data room guests are given the redacted copy.

Which files can be redacted?

PDFs. Save Word, Excel or PowerPoint files as PDF first.

Is redaction charged separately?

No. It is part of the data room on the Advisory and Firm plans.
