An invoice follow-up assistant that keeps receivables moving
An AI invoice follow-up assistant checks which invoices are overdue, works out how late each one is, and drafts a reminder to match: a gentle nudge at a few days late, a firmer note for a repeat delay. It keeps up the receivables habit most small businesses mean to keep and rarely do, which is checking who owes what and saying something early.
You set the rule once, such as flagging anything more than seven days overdue, and your operator runs the check on the schedule you choose.
What you hand off
An invoice follow-up instruction usually covers:
- Checking your invoicing or accounting records on a schedule and finding anything past its due date
- Grouping overdue invoices by age, such as 1 to 7 days, 8 to 30 days, and 30-plus
- Drafting a reminder whose tone matches the delay: a light nudge early, a more direct note the longer it goes unpaid
- Citing the invoice number, amount and due date in each reminder
- Flagging a client who’s been late more than once or twice in a row
- Keeping a running list of everything still open, sorted by how overdue it is
A weekly run, worked through
Say Sam runs a small consultancy and tells their operator: “Every Monday, check which invoices are more than seven days overdue and send a polite reminder. If the same client is late twice in a row, flag it to me instead of sending automatically.”
On a normal Monday, the operator checks Sam’s invoicing records and finds two overdue invoices: Acme Inc at nine days late and Thornquist Ventures at eleven. Neither client has been late before. It drafts a short reminder for each with the invoice number, amount and original due date, written to assume an oversight. Both drafts land in Sam’s morning brief for approval, since anything sent to a client in Sam’s name waits for a yes. Sam approves both on their phone, and they go out within the hour.
Three weeks later, Thornquist Ventures is late again, the second time in a row. The operator drafts no reminder this time. It flags the invoice to Sam with the payment history: two late payments in the last month, both settled within a week of the reminder. Sam decides to call Thornquist Ventures and tells the operator to hold that invoice out of the standing rule until the call happens.
Acme pays before the following Monday’s check. Once Sam’s records show the payment, the invoice drops off the overdue list and no further reminder is drafted.
What stays with you
Checking records, sorting overdue invoices and drafting reminders need no sign-off, since none of it reaches a client or changes anything outside your operator’s workspace. Sending a reminder waits for you by default, because it puts a message in front of a client in your name. Changing payment terms, adding a late fee or writing off part of an invoice always waits for you as well.
If you send the same reminder for the same kind of invoice often, such as a standard first notice at seven days, you can pre-approve that case so it sends without a review. A second reminder, a repeat late payer or a client you’ve marked as sensitive still comes to you.
Setting it up
- Connect the invoicing or accounting record your operator should check.
- Give it the standing order: the overdue threshold, the age groups, and the tone for each stage.
- Set your approval rules: which reminders go out pre-approved and which always need your review.
- Tell it what counts as a repeat late payer and what happens when one comes up, such as a direct flag to you or a firmer note.
From then on it keeps the overdue list current, dropping invoices as they’re paid and adding new ones as they cross your threshold.
