The Problem

Every service business has them — the clients who are a month late, then six weeks, then you stop counting. Chasing them is uncomfortable, time-consuming, and almost always inconsistent. You send a reminder when you remember to, skip it when you're busy, and write off the amount when it gets too awkward to bring up again.

The deeper problem is that most owners treat every late invoice the same way — one generic "just a reminder" email to the client who's always two weeks behind and the client who's never missed a payment in three years. That's the wrong tone for both of them, and it doesn't get results from either.

The real cost

Industry research consistently shows that invoices more than 90 days overdue are collected less than 25% of the time. Every week you wait to follow up, your odds of getting paid drop. Most small business owners are losing thousands of dollars annually — not because clients won't pay, but because the follow-up never happened.

How invoice-chase Works

The invoice-chase skill connects to your QuickBooks AR aging report and your PayPal settlements, cross-references them to identify who has genuinely not paid (vs. who paid through a channel you haven't reconciled yet), and then does something no generic invoicing tool does: it scores each customer.

The biggest win

Tone-matched reminders sent to every overdue customer — firm with repeat late-payers, gentle with good ones — without you writing a single word. Your best clients get the treatment they deserve. Your problem clients get the message they need.

Who This Is For

This skill delivers the highest value for business owners who invoice clients directly — rather than taking payment at the point of sale. If any of the following describes you, invoice-chase will likely become one of your most-used workflows:

📋
Service businesses with recurring client invoices — consultants, agencies, accountants, lawyers, contractors. You invoice the same clients month after month and the relationship matters.
📅
B2B businesses with net-30 or net-60 payment terms — you extend credit to clients and rely on those payments arriving on time to cover your own obligations.
Any owner spending more than an hour a week on AR follow-up — that time is better spent on revenue-generating work. Invoice-chase handles the follow-up so you don't have to.

What You Actually Get

After invoice-chase runs, you receive an approval summary showing every overdue invoice, the customer's payment score, the draft reminder Claude has written, and the channel it will use to send. You review the table, make any edits you want, and approve with a single click.

Nothing sends without your say-so. If you want to hold a reminder for a client you know is having a hard month, you can. If you want to tighten the language on a repeat offender, you can do that too. The skill does the heavy lifting — the judgment stays with you.

A note on tone

The tone-matching is based on actual payment history, not assumptions. A client who has paid on time for two years and is three weeks late for the first time gets a gentle, relationship-preserving reminder. A client who has been 60+ days late three times in the past year gets a firm, professional message that makes the urgency clear. Claude knows the difference — because your QuickBooks data does.

The SmartDesk AI Advantage

You could use a standard invoicing tool to send automated reminders — most of them offer it. But they send the same template to everyone, on a fixed schedule, regardless of the customer relationship or payment history. The result is reminders that feel cold to your best clients and toothless to your worst ones.

SmartDesk AI connects invoice-chase to your actual QuickBooks data and payment history, configures the scoring criteria for your specific client mix, and ensures the output sounds like you — not like a billing department template. William A. Green Jr. sets this up personally during your onboarding session and tunes it to your business before you ever see a draft.

The difference between a tool and a system is configuration. Invoice-chase comes pre-built. SmartDesk AI makes it work for your business.
