For a lot of small businesses, the work isn't the hard part. Getting paid for it is. Invoices go out days after the job because nobody had time to build them, and reminders go out late, or not at all, because chasing clients is awkward and easy to put off. This module covers how the Invoicing Agent and the Payment Chaser take both jobs off your plate.
How common late payment is
In Intuit QuickBooks' 2025 survey of around 2,487 U.S. small businesses (0–100 employees, January 2025), 56% said they were owed money from unpaid invoices, averaging $17,500 per business, and 47% had a portion of their invoices overdue by more than 30 days (QuickBooks Small Business Late Payments Report, 2025). Those are averages across many businesses, not a prediction for yours, but they show how normal it is to have real money tied up in late invoices.
Invoices out the same day
The Invoicing Agent builds invoices from the records you already keep: tracked hours for hourly work, completed phases for lump-sum work. When a phase closes, or every Friday for hourly clients, it drafts the invoice, checks it against the estimate, sends it, and syncs it to your books. Anything unusual, such as hours well over the estimate, waits for your review instead of going out.
Polite reminders that escalate
The Payment Chaser checks for overdue invoices every weekday and sends reminders on a schedule you set. A common pattern:
- A few days before the due date: a friendly heads-up with the invoice attached.
- Just after the due date: a polite note that it's now due, with a pay-now link.
- Around 30 days late: a firmer reminder that asks the client to confirm a payment date.
- Around 60 days late: this one comes to you first. A final notice is a relationship decision, not a routine task.
Every reminder includes a pay-now link so paying takes one click. When the money lands, the agent marks the invoice paid in your accounting software and stops the reminders, so no client gets chased for something they've already paid.
When to involve you
Chasing invoices is routine. Disputes aren't. Set the agent to stop and hand the conversation to you when a client questions the amount, mentions a problem with the work, asks for a payment plan, or replies with anything other than a payment date. Consistent reminders can help, but they aren't a guarantee that a client will pay sooner. What automation does guarantee is that no invoice gets forgotten and you're not the one sending the awkward emails.

A Payment Chaser sends every reminder on schedule, with a pay-now link, and only brings you in when a client pushes back. It can't promise a client pays sooner, but it takes the chasing off your plate and makes sure no late invoice gets forgotten.
Results are illustrative and based only on your inputs. Cash in late invoices = late invoices per month × average value × average days late ÷ 30. For context, in Intuit QuickBooks' survey of around 2,487 U.S. small businesses (January 2025), 56% reported being owed money from unpaid invoices, averaging $17,500 per business, and 47% had a portion of invoices overdue more than 30 days (QuickBooks Small Business Late Payments Report, 2025). Those are survey averages, not a prediction for your business.
