What are late invoices really costing you?
Every invoice that's paid three weeks late is money you've already earned but can't spend, plus someone's hours every week writing "just following up" emails. Put in your own numbers and see the cash stuck overdue right now, what chasing it costs in a year, and how fast automating the chase pays back.

How the math works
- Late invoices per month = invoices sent × the share paid late.
- Cash stuck overdue = late invoices per month × average amount × (average days late ÷ 30). It's the steady-state balance: late invoices keep arriving while the older ones sit unpaid.
- Chasing cost per year = hours per week × hourly cost × 52.
- Financing cost = cash stuck overdue × line of credit APR. Zero if you leave the APR at 0.
- Total = chasing cost + financing cost. Payback = $3,500 ÷ the monthly total. It assumes the automated chase takes over the reminders and shortens the float, so treat it as the upper bound.
- These are your numbers, not industry averages.
An invoice-chase lane that runs by itself
I set up one workflow in the tools you already pay for: a friendly reminder on day 3, a firmer one on day 7, a final notice on day 14, each with a payment link, and anything still open gets escalated to you with the customer's history. Payments sync back to QuickBooks, Xero or your CRM so nobody gets chased after they've paid. $3,500 once, live in 7–10 days.

Questions
What does the automated invoice chase actually do?
It watches your invoicing tool for anything past due, sends reminders in your voice on a schedule (day 3, 7 and 14 by default), includes a payment link every time, and stops the moment a payment lands. Anything still unpaid after the last notice is escalated to you with the history, so the awkward call is the only part you still do.
Do I need to switch invoicing software?
No. It runs inside QuickBooks, Xero, FreshBooks, Jobber, Stripe or whatever already sends your invoices, using their reminders, email and payment links. If your tool truly can't do it, I'll tell you before you pay.
Why count the cash stuck overdue if I eventually get paid?
Because you can't spend it while you wait. It's money you've already earned that's covering your customer's cash flow instead of yours. If you borrow to bridge the gap, the APR line turns that into a real dollar cost; if you don't, it's still capital you can't put to work.
Where do the default numbers come from?
They're editable starting points for a small service business, not statistics. Replace every one with your own numbers; the result only means something with yours.
