FAQ

Questions we get asked

Are these tools really free?

Yes. There is no signup, trial or usage limit. They're free tools from Pyalm, which also makes Pyalm Books accounting software.

Is client data uploaded anywhere?

No. Every tool on this page reads and processes your data in your own browser. You can verify this by disconnecting from the internet after the page loads — the tools still work.

Can I use the results in audit working papers?

The tools support the mechanics — sample sizes, matching, totals, exports. Methodology, judgement and conclusions remain yours; each tool notes its method and assumptions so you can document them.

Do these replace audit software?

They cover common, repeatable checks for small and mid-sized engagements and internal reviews. Firms with large populations or complex audits will still need dedicated audit software.

Can I suggest a tool?

Yes — email hi@pyalm.com with the check you currently do by hand. Several tools here started as exactly that kind of request.
