Free tick marks & calculator tapes for Adobe Acrobat
The Debits plug-in gives you tick marks, workpaper stamps, sign-offs, a calculator tape, bookmarks and cross-reference links right inside Acrobat. Free, with no account and no trial clock.
Windows 10 or 11 · Adobe Acrobat Standard or Pro (Adobe Reader can't run plug-ins) · No sign-up
Everything you tick and tie with — at no cost.
No account, no license key and no time limit. Every mark is saved as a standard PDF annotation, so anyone who opens the file sees it.
Tick marks, stamps & sign-offs
40 tick marks — standard symbols, tax and audit codes (F, XF, TB, PY, GL…) and review flags — plus 10 workpaper stamps like Footed, Agreed, Traced to balance and Prepared by client. Add up to 24 of your own. Sign off as preparer, reviewer, manager or partner with your initials and the date.
A calculator tape on the page
A 10-key adding machine inside Acrobat. Select figures on the PDF to add them, label each line, subtotal, cross-foot against a figure on the page, export to CSV — then stamp the tape onto the workpaper as the audit trail of your arithmetic.
Markup
Highlight, underline, strike through, text boxes, sticky notes, arrows, rectangles, circles and freehand ink — in the colours you choose.
Bookmarks & cross-references
Bookmark a page, or build a workpaper index that bookmarks every page in one click. Link a figure on the return to its supporting schedule so a reviewer jumps straight to it.

Questions
Is the Debits plug-in really free?
Yes. The review tools — tick marks, stamps, sign-offs, markup, the calculator tape, bookmarks and cross-references — are free with no account and no time limit. Workpapers and sending a return for e-signature are part of a Debits plan, which you can start on a 7-day free trial.
Do I need a Debits account?
No. Install the plug-in and the review tools work straight away, even offline. You only sign in if you want Workpapers or to send a document for e-signature.
Does it work with Adobe Reader?
No. Adobe Reader can't run plug-ins, so you need Adobe Acrobat Standard or Pro. The installer checks for it.
Does it work on a Mac?
Not yet. The plug-in runs on Windows 10 and 11 with Acrobat Standard or Pro.
Will people without the plug-in see my tick marks?
Yes. Every mark, stamp, sign-off and tape is saved as a standard PDF annotation, so it shows in any PDF viewer, including Acrobat Reader.
Do my PDFs get uploaded anywhere?
No. The review tools work on your computer and never upload your documents. The plug-in counts how often each tool is used — counts only, never document content — and only sends those counts if you sign in to Debits.
Can I make my own tick marks?
Yes. Alongside the 40 built-in tick marks and 10 workpaper stamps, you can add up to 24 custom marks of your own.
