What it does

What Sauna does for accounts receivable specialists

01
Build the aging report
Sauna pulls open invoices from QuickBooks, builds the AR aging in Google Sheets by customer and bucket, and ranks accounts by overdue balance and days past due.
02
Draft dunning emails
It writes the right reminder for each bucket — friendly at 30, firmer at 60, final notice at 90 — pulling invoice numbers and amounts, and holds them for your review in Gmail.
03
Apply and reconcile payments
Sauna matches incoming Stripe payments to open invoices, drafts the cash application, and flags short payments or unapplied amounts for you to resolve.
04
Summarize disputes
It reads the customer's email thread, pulls the disputed invoice and any credit memos, and drafts a dispute summary so you can decide on a credit or escalation.

Good to know

Questions, answered.

Will it email customers without me seeing it?

No. Every collection email is drafted and waits in your queue. You approve the tone and the timing before anything reaches a customer.

Can it misapply a payment?

It matches payments to open invoices by amount and reference and shows each match. Anything it can't tie cleanly — short pays, overpayments, unapplied cash — it flags for you instead of forcing a match.
