What it does

What Sauna does for payroll specialists

01
Validate pay inputs
Sauna pulls hours, PTO, and changes into Gusto against the schedule, drafts the exception list for missing punches, unapproved overtime, or new-hire gaps, and holds the run until they clear.
02
Build the pre-run audit
It compares this run to last in Google Sheets line by line, flags every employee whose net pay swings beyond a threshold, and shows the reason before you commit the run.
03
Reconcile and report
Sauna ties the payroll totals back to the GL in QuickBooks, drafts the funding and tax-liability summary, and flags any account that doesn't reconcile.
04
Answer pay questions
It reads the employee's message, pulls their pay stub and the relevant earning or deduction, and drafts a clear explanation, ready for you to send.

Ask in chat. It does the work.

Sauna shows up where you already work — the web app, Slack, email, iMessage, and Superhuman. It reads what it needs, does the task, and comes back with the draft for your approval.

Good to know

Questions, answered.

Will it run payroll without me?

No. It validates inputs, builds the audit, and surfaces exceptions, but the run is committed by you. Nothing pays out until you approve the pre-run audit.

Can it catch a pay error before it goes out?

Yes. The pre-run audit compares every employee to the prior period and flags net-pay swings, missing approvals, and unreconciled totals with the reason, so errors surface before the run, not after.
