The same four steps a part-time AR assistant does each week, from the report you already run.
Export A/R Aging Detail from QuickBooks Online or Desktop as CSV or Excel. Map the columns once; the next upload maps itself.
The aging has no addresses, so paste a customer and email list. Anyone without one is listed to call, never emailed.
See every email of the first batch before it goes. After that, reminders go on weekdays from 8:00 your time.
Total past due and the change since last week, the top customers, promises coming due, and who needs a call.
One plain email per customer, signed with your company name. Replies go straight to your inbox. The 60 and 90-day notices are firmer, never rude, and you can rewrite each one.

No. You export the A/R Aging Detail report as CSV or Excel and upload it. You map the columns once and it remembers them. Upload a fresh export whenever you like.
From your next aging upload (an invoice that is gone is marked paid, a smaller balance is logged as a partial payment) or when you mark it paid. It does not watch your bank or read replies; replies go to your inbox.
The aging report has none, so you paste a customer and email list once. Customers without an email are never sent anything and are listed so you can call them.
The first batch waits for you to review it and press Send. After that, reminders go out on weekdays from 8:00 your time, at most one email a day to each customer. Every email has a link that stops our emails to that address.
The reminders stop and the customer appears in your Monday summary as needing a call. It does not phone anyone or add late fees.
Up to 150 customers and 1,500 open invoices on one report. Each customer gets at most one email a day, listing every invoice that is due a reminder.
Yes. The free sample shows an aging report bucketed by days past due and the exact email each customer would get, and you can run your own export through it.
Reminders and the Monday summary stop. Your uploads, customer emails and the invoice log are kept for 30 days after cancelling, then deleted, and you get an email with the date. Subscribe again before then and everything is as you left it.
