Find overdue invoices in Slack and draft the reminders

To get an overdue invoices report in Slack, mention @Glad and ask: "which QuickBooks invoices are more than 30 days overdue? Give me a CSV." Glad reads your receivables, groups them by customer, attaches the file in the thread, and can save a reminder draft for each customer in your Gmail. For this job Glad only reads and drafts. Every email send waits for your yes, one by one.

How to chase overdue invoices with Glad

1
Connect your own QuickBooks account, plus Stripe and Gmail if you use them.
Glad sees what your QuickBooks permissions let you see, nothing more.
2
Ask in a channel Glad already belongs to, or invite it to a private finance channel so the numbers stay with the people who need them.
3
Ask for the list with an age cutoff and the format you want, such as a CSV or totals by age bucket.
4
Open the drafts in Gmail and edit them.
To send one, tell Glad which; it asks for your yes before each email goes out.

Asks first

Send an email, send a draft, reply to a thread

Slack: the report arrives as a reply, or as a CSV, text or Markdown file in your thread.

Other ways to do this

The manual way is the A/R aging report in QuickBooks, then one reminder at a time from your inbox.

QuickBooks has its own assistant for the chasing part. Intuit's help article says you can "Let your Payments AI remind your customers to pay invoices that aren't paid by the due date," and that it "suggests a specific schedule for invoice reminders, which you can review before approving." There is a catch on reach: "The Payments AI is only available to customers in the US that are subscribed to Essentials, Plus, Advanced, and Intuit Enterprise Suite."

For alerts in Slack, Zapier's QuickBooks and Slack page lists ready-made automations such as "Send Slack messages for new invoices in QuickBooks Online" and "Send Slack channel messages for due invoices in QuickBooks".

Where they are better: if you want reminders to go out on a schedule, or a Slack alert the moment an invoice falls due, QuickBooks Payments AI or a Zapier automation does that, and Glad does not. Glad fits when someone asks a question in the moment: who owes what, has this customer paid in Stripe, draft the reminders so I can check them first.

Limits

You need your own QuickBooks connection, plus Stripe and Gmail for those parts. Glad reads only what your own permissions allow.
No timer. Glad will not alert you the day an invoice turns overdue, and it will not send monthly reminders. No scheduled jobs yet. They are planned.
Glad reports what your books say. It does not reconcile bank data, and it is not accounting advice.
This job is read and draft only. Glad does not record payments, refund or charge anyone as part of it.

Questions

How do I see overdue invoices in Slack?

Mention @Glad in a channel it is in and ask which invoices are overdue past a cutoff. Glad reads QuickBooks through your connection and replies with the list, and a CSV if you ask for one.

Can AI chase unpaid invoices for me?

Glad drafts the reminders in your Gmail and sends only what you approve, one email at a time. If you want reminders sent on a schedule, QuickBooks Payments AI does that for eligible US plans.

Can QuickBooks send overdue reminders automatically?

Yes, for some accounts. Intuit says Payments AI suggests a reminder schedule you review and approve, and it is available in the US on Essentials, Plus, Advanced and Intuit Enterprise Suite.

Can I check a customer's Stripe payments from Slack?

Yes. Ask Glad whether a customer has paid in a given period. It searches Stripe customers, charges and invoices through your connection and answers in the thread.

Can I export the overdue list as a spreadsheet?

Yes, as a CSV. Name the columns you want, such as customer, invoice number, due date, days overdue and balance, and Glad attaches the file in the thread.

Does Glad check for overdue invoices every month on its own?

No. Glad has no scheduled jobs yet; they are planned. Ask at the start of the month and the report comes back in the thread.
